I own a 2001 Grand Cherokee Laredo 4.0 I6. Problems I’ve run into that seem to be common with the 4.0 I6 WJ: -Brake light housing bad connection (causes brake lights to go haywire while running lights are on) -Window regulator failure (always keep wedges for windows on deck) -Calipers tend to warp rotors (causes death wobbles only when braking) -Radiator leak causing overheating (plastic top hose intake cracks) -Cylinder 3 misfire (caused by heat soak) -Struts fail (struts under hood and tailgate fail) -Knocking noise from transmission (flex plate and torque converter bolts come loose and make knocking noise) -A/C doors get messed up -Valve cover gasket oil leak -Body Control module failure (running lights flicker, horn honks, displays flicker, etc.) -Side mirrors get loose and fold too easily (can be pushed close by wind) -PCM failure (power control module fails causing car to stall while driving or idling/will not start) -Transmission fluid leak -Carbon build up in throttle body (just needs cleaning) -Hose to pcv dry rotted (easy fix) -Water pooling up in passenger floorboard (AC condensation drain gets clogged, clean line with a wire) -Cam shaft position sensor failure (can also cause misfire) -Door skin panel clips break easily (I have a burning hate for those clips) -Brake dust covers ABS sensor causing ABS light -OEM Front door 6X9 Speakers blow out easily That is about all I have run into over a long time of owning a WJ. Quick tip: if you have a OBD II scanner that isn’t picking up codes always check the onboard scanner, start with key in off position then turn it to the start position without cranking, repeat 2 more times and this will tell you all the codes.

[@tophersupreme5573]

I have a 2004 with 301000 miles and I've only a few issues. Best automotive purchase I ever made.

[@jasonprince8655]

2004, 4.7L, 197k and I have had only the rust issue. Living in Salt belt, so I will have rust issues with any vehicle.

[@Kanakid]

2004 was the best year of the WJ. I have one with 200,000 miles it still runs great. High Output motor.

[@DL-by8el]

What engine and what gas milage.

[@FromSaultoPaul]

AWESOME. I just bought one from a friend but now ex-friend. He raised the offer price just before I bought it by $300. Oh well, it was a 04 Grand Limited WJ with 145,000 ml. He had the big package of the 4.7L. He had a cover for it but parked it and never used the cover. So far it is tires, a battery and power steering pump. Hopefully no more problems with it as I got for 1/3 book price. WHAT A BLESSING.

[@ascendantrobin3230]

@@FromSaultoPaul its an awesome jeep! i have yet to sit in a car that has seats as comfortable as the leather WJ seats! I6 or V8 are both great engines and are reliable when you perform routine maintenance and keep them from overheating, they can run easily to 250,000miles

[@brandanbouchez8412]

You didn't say anything about all the broken wires in the door jambs

[@idahospyder1620]

I've had to fix the drivrs side a few times.

[@jasnonya3005]

That's most often the ground wire in my case

[@THEDRIVINGPROFESSOR]

[@ascendantrobin3230]

haha i thought i was the only one thinking of that!! 🤣 yep, rewired the driver door wire boot too many times!

[@wbball15]

AMEN

[@ericstathis67]

I have an 04 limited as well as an 18 cherokee trailhawk and the WJ is still my daily driver. I put over 200k on it myself after I bought it in 05. Over the years I've had plenty of issues: thermostat, new radiator, starter, alternator, FIVE window regulators, rebuilt front diff, new crankshaft, front cd player eject broke and no clock or radio display. Also a few batteries, brake jobs and tires and tons of light bulbs. There is also a gremlin which will turn on the rear lights that won't turn off unless u drive forward. Original exhaust, although the hanger broke a few times. It also leaks oil like a civ having said all that, it runs great, has a perfect driving position, excellent vision all the way around and it's a blast to drive. I love it!!

[@charlesknight5140]

Gotta love those Gremlins. LoL have a Blessed day

[@digitaldreamer5481]

I replaced my thermostat with a cheap one from the local auto parts store and noticed that it didn’t have the small circulation hole near the top like the old one, reside in the warm climate of Hawaii. So I put the new thermostat in place to mark where I was going to drill a small hole towards the top. I used a 7/64 drill bit and made my circulation hole, then did the install. While I was at it, I replace the coolant sensor, which is easier to replace outside the vehicle. The whole job took me about 35 minutes and has been working great for almost a year now. Great video! 5 Stars in my book. I love my Jeep!

[@pronmaster09]

This is actually very interesting I've owned 4 of these guys for over 8 years now and I only get the seals issue. super interesting! They are super reliable, and I haven't had your specific problems, and on top of it the jeeps are way easier to work on than modern cars. but great video very interesting to learn what people get into working on these things, also great topic with the rear control arm that was a great touch.

[@derekwillbanks5645]

My favorite problem on these jeeps is the door jam wires that break and cause all sorts of wierd electrical gremlins.

[@g.cosper8306]

Drivers window got stuck halfway up AND after turning off the vehicle it wouldn't start. One mech told me it was up in the engine area because he used his jump starter to avoid the interlock and the car started; estimate 300 bucks for parts alone. After research, I cut open the boot holding the wiring between the drivers door and the engine compartment, found a broken wire and fixed it with a band-aid. Did go get the proper wire bridge that day and has been fixed for the past 5 months for $12.

[@joeyhdz3435]

great explanation my friend! of everything... very humble, great job! keep up the good work .

[@francescobailey101]

I have a 2003 Jeep Grand Cherokee 4WD exactly like the one in the video and I've had it for 7 years now. It's still the most reliable car I've ever had but the issues he described are very accurate because I'm currenting having differential problems which is not cheap.

[@rustyshackelford4613]

My brother warned me about that, exactly how expensive is it ?

[@lostbooks2918]

$750 cheapest usually over $1000

[@jsavage9134]

The blend door is simple though, get you some hvac tape and change it yourself every year, it’s more annoying than anything!

[@baconstrips6260]

Thats a 2004 WJ in the video not a 2003.

[@tinysampson8832]

I have an 2004 I'm second owner n I've had a few issues but watching this I think my thermostat is sticking. No differential trouble yet. 200000 plus miles

Very helpful info. Thank you very much. I love to watch your videos.

[@wincatalcala6258]

Love your channel, very informative. Keep it up!

[@Bulletz4Breakfast13]

You should add the door harness wires breaking from normal use of the front doors, causing power windows, power locks, power mirrors to fail. In some cases a ground wire in door can cause issues with ECU that controls the fuel trim and other things

[@fatherof3792]

What's the fuel trim? Found broken wires in Driver's door and all of a sudden it won't stay on...

[@stevencharlton7801]

2003 4.7L HO Overland, owned for 15 years now. Blend doors was the only one I have encountered. 3 times. Eventually had them welded open so only warm air comes through. AC in UK is hardly an issue. Other than that, best motor I have ever owned. Nice vid.

[@lyndseyhunter9244]

Steve I'm in the UK! You sound like someone who knows a bit about these jeeps. I could really do with some advice on mine as no one has any knowledge on it as they don't know older 4x4s

[@darrena.247]

Excellent video. Thank You.

[@dantee323]

Very helpful. My front diff is leaking and this helped me realize how to fix it

[@davidwarnick]

The extra added problem fit my 2004 Grand Cherokee to a "T"! Drove far too many miles before I found the problem, but once fixed, my Jeep runs like brand new!

[@juliorosas-cortes424]

I’m about to go look at one, I took notes! Thanks.

[@henrypetersen4133]

Window regulators: If you live in a hot area like central CA, the plastic in the window regulators break easily. Here's what to do to avoid breakage, when you roll the windows all the way up, release the cable tension by momentarily pushing the "down" on the window switch. When lowering the window all the way, push the up on the switch to release the cable tension. You can thank me later.

Nice! I'm in the process of picking up a 01 Laredo with the 4.0 as a project. Seems mechanically sound save for a head gasket (relatively easy fix) but it does run with a miss due the gasket bleeding compression between 5 and 6

I got tools to help me work on the Jeep now (jack stands, floor jack, and a creeper) so I can better work on it. Pretty soon I'll be replacing the power steering pump, oil pressure sensor, the thermostat and possibly the water pump.

Had a 2001 4.7 limited, worst car we have ever owned! Failed once every one or two months. Sometimes the key wouldn’t even turn, and all you heard was that typical chrysler ding ding ding sound, which brings me really bad memories.

[@manbearpig2164]

This is a ridiculous video, jeeps last longer that most vehicles, these so called problems happen to other vehicles all the time

[@654Crossman]

@@negrokrilinful the first 4.7s were kind of crappy. It was the first DOHC V8 used in a jeep. It had aluminum heads like the previous 5.2s. The first 4.7s had a bad tendency of overheating and causing catastrophic damage, quickly. However, I have seen later 4.7s and even old rebuilt ones that have lasted well over 200,000 miles. I prefer my ZJ over the WJs, but they are still fairly easy and cheap to fix...

Good video. I love the WJ series Grand Cherokees. I have 2 2004 WJs, one with the inline 6, the other one is a special edition with the 4.7 V8 all time 4WD. I have had to replace the window regulator on the special edition and I had to do new seals on rear differential, axels, ball joints on the 6 cylinder. Over all these are great vehicles for where I live (Colorado) and would probably buy another one if it was in good shape with lower miles. So much more comfortable than the XJ.

Great video, but i would like to hear if a job is hard or easy and whether its cheap or not to get repaired. Really adds to my purchase descisions. :)

[@OutnBacker]

The first two issues are almost a given with Chrysler. Have been for the last 50 years. Poor wiring, poor grounding, poor attention to details and low bidding of parts. Broken locks, windows, gauges, etc. Most of the other items are pretty much in the box for all vehicles. Chrysler always had great engines, differentials and transmissions. Heck , the rear end in the Jeep Cherokee from 1985 til the end had the same dif as the 1964 Doge Dart/Plymouth Valiant. Nobody ever complained about that. But we sure complained about that window that didn't work or the door locks that failed.

Literally bought a 2000 WJ Limited at auction for $4,402 last week. Probably the same day you posted this video~

[@12345gizzmo]

You didn't mention the most serious problems ones with 0331 heads cracking between 3/4 cylinder and piston skirts breaking off and the wiring in the driver's door shorting out or breaking causing your security system to go off every time you put the key in to unlock the door

[@1AAuto]

+lynn hurd Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c

[@justinhappel9169]

My horn honks every time I unlock with the key. Good to know why. Lol

[@chasermalloy7406]

Well the heads cracking is most commonly cause by incorrect maintenance of the cooling system. Doesn't matter how many warnings there are in manuals or stickers in the engine bay, people don't bleed the system properly after refill. "the air works itself out " is the common cry. Well it doesn't in many engines. That's why bleeding is essential. The other thing people can't get through their heads is that when a modern car overheats you STOP. Oh, we're only 8 miles from the mechanic or it's only 7 miles back home..it'll be ok. Well it WON'T be ok. Even an expensive tow is a lot cheaper than a new engine. Use your heads and you won't crack your heads.

[@toddrhine7648]

Do you have a video on the 1st Generation Grand Cherokee 1993. Would be great as I know many that have them to this day.

[@edgardorojas4693]

I have a 2000 Jeep Grand Cherokee 4.7 Liter Limited. I changed all four oxygen sensors and I still have the same issue. The issue is that sometimes it stalls on me and sometimes when I hit the gas it starts ti jerk and makes a loud noise while I’m pushing on the gas. Once I let go of the gas after a few seconds it goes back to normal and drives ok. However it does it every day while I drive. Sometimes when I turn it on I can hear the idle go up and down and sometimes it shuts down the engine. I thought it was the TPS but after searching on KZbin it doesn’t give me all of the Simpson’s that a vehicle have when it has a bad TPS. Thanks for talking about the top five issues. I know I have a bad blend door on my Jeep. I have to fight with it until it finally blows either cold in summer or hot in winter. I hope to hear from you, thanks, Ed.

[@elenasjuanlove47]

That video nailed it. I'd love help researching a problem I'm having with that exact same jeep. The front axle loses power randomly when in 4 low. I can leave an email address if need be.

[@TheShift1313]

I've owned a 99 wj since 05 and I've had to do most of the things on your list. Blend door sucked! Here are some of the things that have happened to mine. Blend door. Window reg on drivers door. Window lock out switch( sometimes the rear drivers side window goes down by itself). The auto climate resistor pack connector melted. Overhead console constantly says hood open even though this car has no hood switch. Early brake systems have the brake clip rubs on hub. Crank sensor on the back on the motor. "Distributor" went Radiator tank cracked Rear axle seals are a constant pain Rear upper link rusted out. Rear lower links rusted out. And the big one. #6 piston cracked! Yup. 120k. Probably the most annoying thing is the alarm. If your ignition switch starts going your auto lights might randomly come on when parked. The alarm will not let you lock the car with the key or open with the key or the alarm will go off. Mine is a 99 with 4.0. With the v8 tease and d44 varilock rear cause of the factory towing pack.

[@lordofwar9638]

Idk how they narrowed it down to 5… I was constantly wrenching on my WJ. 😂 Still loved it tho.

[@MikeBrownRehobothBeach]

My 1999 has all those problems and more :) Latest issue is a phantom load that drains the battery and a drivers side door key that no longer opens the door. It goes in the hole, will turn left and right, but won't unlock the door. Battery is dead, so key fob won't unlock the door either. Had to figure out how to pop the hood with a long pole, then recharge battery, then could use the key fob to unlock. What a pain.

[@jimr6121]

Lets be sure if you have the 4.7 V8 ANY TIME YOU DRAIN THE COOLANT read the label on the radiator covering. You must blead the engine or you can drop some valve guides on one of the heads.

[@kevinm5177]

Loved my 2000 GC. But the 4.7 had a bad head design that is prone to cracking. It was an awesome engine for power but it wasn’t worth it to just do the heads or drop in a new motor.

[@654Crossman]

I did a swap with a couple 4.7s. I talked to the engine shop that did the rebuild, and they told me exactly why these first 4.7s were prone to catastrophic damage. The thing that kills 99% of these engines, is overheating. And of course with aluminum heads like the older 5.2l, it is prone to even more damage, when overheated. With that being said, the average rebuild is $2k-$3k, where I'm from. That's still cheaper than a brand new car and guarantees you at least another 200,000 miles, as long as you take care of it.

[@xXDarthBagginsXx]

Brake master just went out on my '01 - already replaced a radiator, rad fan, fan relay (the one hidden behind the bumper cover), waterpump, thermostat, coil packs, upper and lower rad hoses, and the valve cover gasket. Dreading the day I have to replace the heatercore

I have had a 1st generation 1995 gc and it was awesome. Best jeep off road and so reliable. I bought it for $600 and in 10 years i only had to replace battery twice and brakes once. I now have had a 2004, 2000, and now a 1999. The 00 and 04 lasted each one summer before everything started breaking. The 99 has blinker and tail light issues but other than that it has been ok. Nothing beats a 1st gen 1995 with a 2" lift from factory and the only jeep with true part time 4wd and true 4wd low. Look it up. Made it amazing off road.

[@theretrobro]

I Have a 2015 dodge journey nice to see they still haven't figured out the blend door actuator problem

[@johnneumann1080]

The window regulator on WJ is cable driven and usually the plastic guides break. The Blend doors that bind are only the Dual Zone heater systems. This is what the Blend door sub assy was releasd for.

I’ve changed out the differential transfer case lubricant and made sure as used the Mopar specified stuff that matches the tag on the case. It didn’t seem to help, at least immediately. Will it take time or could it be something else. Thanks

Leaking rear axle at the pinion and inside left tire so i have to top it up with oil once in a while. also the abs warning light is on. Oh almost forgot a small leak at the transfer case also. I have resent changed alternator, thermostat and did a AC pump bypass

[@codyburg3tt]

Got a 1999 grand Cherokee limited 4.7 yesterday it runs great but I was told it will randomly shut off and start back up 15-20 minutes later if you have anything you could suggest that would be great. (I was thinking either something getting hot or a fuel air ratio problem)

Was hoping maybe my problem was one. Got an 01 with the 4.0. Misfire is my issue. Starting up cold, it works great. Most of the time it works great starting warm. However, occasionally it will misfire and run like crap on startup. Only until I get moving, then it smooths out. Also, if I leave it running while hooking up to tow, doing a lockout, jumpstart (roadside/off-roas recovery) for more than 5 minutes, sometimes it misfires when leaving for a few seconds. Seems to be pretty much #3 cylinder. I've changed the coil pack and plugs.

I’m considering a Grand Cherokee Overland (2002 to 2004) with the 4.7L H.O. Engine. I plan to tow about 4,000 pounds. Any thoughts?

I have a 2016 jc sport and have had the window thermostat and the heat/cold air problems. But my check engine light goes on and off often. Ill hit a bump it comes on, I hit another bump it goes off..idk

2003 GC Overland 4.7 .. Had the blend door issue twice. Replaced 3 window regulators (both rear windows and drivers window twice). Rear axle seals replaced. For the last 2 years I have been fighting seized brake calipers. All wheels have had seized calipers that had to be replaced with fronts being done twice. Replacement calipers were under warranty but still why?? I think it is the material the pistons are made of .. shrugs. Currently have to replace rear seal on transfer case but no hurry. I use mine mostly in the winter now. Was my daily driver for work until this year. Other than the rockers rusting out (Ontario salt for winter) it has been fairly good vehicle. You definitely want to be able to do the work yourself if you own a Jeep.

I had a '02 with the 4.7 HO for 270k miles until it got hit by a drunk driver... replaced one window motor, radiator, heater core, thermostat, and a starter besides the usual battery, brakes, etc..

[@chasermalloy7406]

Exactly same as my 02 overland

What causes front end differential deflection? I have wheel hop when I first take off and I can feel a slight vibration when driving at low speed? Does it need to be rebuilt?

Hi there, how do you do fuel adjustments, richer or poorer...

I replaced almost everything in my 2002 4.0 6 cylinder engine for under about $400, so I won’t have any problems later on once I got to 165,000k. Replaced radiator, all hoses, 😂water pump, alternator, starter, battery, coil pack clutch fan and electric fan, ac compressor along with a few $10 engine sensors. Parts are so cheap. I just put 4 tires on it and it’s got 245,000k. Doesn’t smoke doesn’t burn oil doesn’t knock or tick. I drive this daily around town and best deal I’ve had outta owning 40 plus vehicles. . Paid $1600 for it. I’ve got tvs in seat head rests and an Xbox hooked up for football tailgating. 😂

So I used to own a 95 jeep grand cherokee that would randomly stall out. Replaced a sensor and it ran fine. Now I have a 02 grand cherokee and it's starting to do the same thing would it be the same issue or something else? Don't want to replace parts if not needed.

No mention of the notorious 4.0 clatter. The top bolt on the water pump oxidizing to the point of being impossible to remove. Fuel injector bodies cracking. And steering stabilizers losing their charge causing the death wobble. Other than that, good vid.

Looking under that rusted out POS sure makes me glad I live in Texas. A 20 year old WJ will still look almost new with no rust what so ever.

We have a 2001 Jeep Grand Laredo with 153,000 miles on it. It had oil leaks and suspension problems. Five thousand dollars later it is mint except for the power steering hose needing to be change due to slow leak. The only problem is that my niece is afraid of it because it has a high center which scares her because she feels it sways a little. I guess we'll have to lower it now.

Why is a bad thermostat a Jeep 2nd gen issue and not a tstat mfr issue affecting many different vehicles?

Greetings from Styria, I am totally enthusiastic about you and your tips and advice👌👍💪. I have a concern and don't know what to do next with my jeep grand cherokee 4.7l v8 built in 2000. It only runs on 7 cylinders. The eighth cylinder doesn't like. I have the ..... Fällercot P0208 .... I have new injectors, new spark plugs, new ignition coils. AND it still runs restlessly and against the fällercot P0208. The spark plugs have sparks, the injectors also work and inject gasoline, what else can I do ?????. Thank you in advance. Greetings from Daniel Förster from Krennach

How expensive is it to replace the rear A arm and the supports below it? Is this something the home mechanic should attempt?

[@dannydisanto1008]
