04 4.0 Explorer XLT. I take good care and keep it well maintained. Never lets me down. I feel two things are true; 1.) If you take care of something and replace things as necessary- you maximize its lifetime. 2.) You can say anything has common issues and obsessively focus on them, or just fix them- because nothing in life is a 100% guarantee.

[@jeffmchenry6348]

Definitely fire up a fatty before working on Exploder's, I find it helps while I curse the engineering flaws.

[@robw5318]

I have a '04 Mountaineer and it had many of these problems after 130k miles. I will look into the other problems that you mentioned because I'm sure that they will be next. Thank you for the valuable info. Great post.

[@Loglakeliving]

Great Video! I have a 2003 Ford Exploder 4x4 with 214,000 miles. You nailed most of the maintenance issues we have had with this vehicle. Although no engine or timing issues as yet we Replaced transmission at 194k miles. I would add a few...the extremely difficult diy parking brake assembly, the easy repair cruise control brake pressure sensor, lift gate cracks and hinge replacement, plastic vacuum hose assemblies under the hood which of course crack. Etc. etc.....HOWEVER, did I mention we have 214k miles. Likely near $50k to replace so I will keep saving a $600+ payment with my Ford Exploder!!

[@wyattoneable]

My brother owned a 2001 Ford Explorer and he had terrible problems with overheating, slipping transmission and rattles, leaks...it was the worst vehicle he ever owned. Your doing a great service by pointing out some issues on that dude.

[@maggiewagmore8778]

Somewhere along the line, Ford replaced the plastic timing chain guides with metal, after so many complaints about plastic disintegrating and ending up in the engine. I have a 2010 4x4, which I was told has the metal guides. Mine was a company lease, with 200k mostly highway miles. It does run and shift great. Turned-in company leases can be a good value, as they have usually been well-maintained and haven't been subjected to the wear and tear of in-town driving. You're right about the thermostat housing. Mine is leaking a bit, so I need to get after it. Coolant sitting on top of the engine block is another sign of this issue. Easy fix. And you're right about the wheel bearings, too. You're also right about the shifter issue. I would just add that there is a pin in the mechanism that moves in and out, allowing the shifter to either move or lock in place...activated by the brake pedal solenoid. I assumed the little circuit board in the white plastic case was the cause of my problem, when it was actually the pin that had broken inside the shifter (it is attached to the actual lever). When it breaks at the attachment point it can work it's way out and won't retract...locking the shifter in park (and not allowing you to remove the key from the ignition..and draining your battery). I'm not aware of a good fix for this, short of replacing the entire shifter console unit. I pushed the pin back in, and for now it shifts fine. This won't last, but at least I know what the problem is when it happens again. With removal of 2 screws, one can lift the console cover enough to push the pin back in. Mine has been fine for several weeks now after doing this. I like my 2010. It's in great shape. It's quiet inside and runs smoothly... but there is some strange engineering going on with these Explorers. Lots of plastic in places where metal would have meant better reliability. I have a 1999 4Runner 4x4 with 338k on it. Runs like a Swiss watch and the build quality is far superior. I'd drive it to California tomorrow. I wouldn't feel so confident in my Explorer.

[@boobalew]

I just finished doing my own Chain/Guide installation on the 4.0L SOHC and have named my Explorer "The Car From Hell"!

[@mumbles552]

My '02 explorer has the 4.6 V-8 which are famous for leaking oil around the oil filter adapter which bolts onto the side of the block. Being a 4x4 with power steering, there was no way to get at the bolts holding it on so i had to drop the front differential to change the leaky gasket. While it was out, i resealed the diff and replaced the U joints, tie rod ends, front struts, CV joints and stub axles, rotors, calipers and pads, sway bar bushings, and anything else which needed it. Once it was all back together, I did the rear axle including new clutches in the locking rear end. It's like a new vehicle again with 378k on the clock! Oh yeah, to replace the front driveshaft seal in the transfer case, I had to drop the transfer case and split it to get at the seal. It's a labor of love.

[@davidhoulden5791]

Very happy with my 09 4.6L. No issues other than the wheel bearings as mentioned.

[@vegasfordguy]

My 2004 Explorer has 130,000 miles on it currently. So far everything has been rock solid except for the front wheel bearings which are just starting to rumble. I ordered a set of Moog replacements and will replace them soon. Many of these problems are lack of maintenance related issues. I have no leaks or wet spots around the rear diff, actually no leaks anywhere at all. I did have to replace the thermostat housing around 100,000 miles. Super easy and open access. I change all of the fluids regularly. Engine oil, trans fluid, transfer case, rear diff, coolant, power steering and brake fluid. I usually chang the engine oil every 8k with 5-w30 mobile 1 synthetic or whatever synthetic is on sale. I always make sure to use an OEM Motorcraft oil filter. I do a transmission pan drop and fill with filter every 30,000 miles and only use OEM Motorcraft Mercon V trans fluid. For the front and rear diffs I use fully synthetic 80/140 gear oil and the transfer case gets Mercon trans fluid. Never use Mercon V in the transfer case. Oh yeah, original brake rotors all around and not warped. I'm easy on my brakes and use the O/D overdrive off for engine braking whenever I'm going down a steep hill to conserve the brake pads. Especially when towing.

The 5.0 litre V8 on the 2000 model has been really solid. Always runs, never had a check engine light. If you have a light foot you can get over 20 mpg. Step on it and you will get about 18.

Let me know if you want to sell it

[@northdakotaham1752]

@@jeff-wv8te I now have 235k miles on that Explorer and the rear brakes are in need of replacement. All highway miles. Those are original pads from new. The emergency brake cable must have been hanging up as those brake shoes are entirely gone. (Rear disks with built in shoes for the emergency brake). Not sure how that happened as i never, ever use the emergency brake. The passenger side rear axle seal was also leaking oil into the brake. Other side ok. So I have it all apart and have all the new parts including new brake cables. Will be replacing both axle seals while it's apart. I have a 2010 Explorer 4.6 V8 that I drive while the old one is being repaired.

Good truck except door and window controls and dome light (door ajar) electric always messes up after 100k miles so i just rewire switches as theu ware out.

[@kuaekid]

We had problems with the Air Conditioner. When the vacuum lines get brittle and break it prevents airflow control for the main and lower vents keeping the air on the windshield only. Also, the EGR vacuum lines and A/C vacuum control lines are controlled by a check valve. If it fails it's an easy, inexpensive fix some mechanics won't tell you about.

[@trappy77]

I have two Explorers and an Aviator, 2003 Explorer awd 4.0 190,000 have owned this 5 years and 50,000 miles have replaced brakes only and one front axle. Plus regular maintenance, oil changes transmission fluid. Currently needs axle seal replaced and upper control arms front due to rust, but all joints are solid. 2004 Explorer 4wd 4.0 has 309,000 has been well maintained bought used recently. have all maintenance records. plus what I have done 4 wheel bearings were replaced brakes all around 3 times. 8 sets of tires. Rear differential has been resealed two times. It is getting timing chain slap now, probably needs engine pulled out and timing done. burns no oil shifts great. Transfer case shift motor has failed two times. fuel pressure monitoring sensor failed before. All electrical switches in both Explorers work windows work never had the doors apart. no issues. all options work as designed The 2003 aviator 2wd 4.6 v8 181,000 has had a bad water pump in the past needs a wheel bearing runs and drives great. power steering pump is noisy. annoyingly the paint has worn off lots of buttons inside and some switches need replaced. door ajar switch failed on driver door needs replaced.

[@chadharmon5716]

Dave Allen first and second generation explorers are much better than these shit boxes

[@dannyl2598]

Thanks Tim. We have the same one as the gray one. We had to have the rear end replaced under warranty and again later because according to Ford, if all four tires are not EXACTLY the same circumference, it will destroy the rear end. It apparently locks both wheels together because it thinks you need better traction. This is a problem when you are trying to back out of a parking space. It can also try to force it in to four wheel drive a 65 Miles per hour. BTW, we also experienced most of the other things you talked about. On the other hand it now has 290 K miles on it.

I own a 2004 Explore watching your video is déjà vu everything that you discussed in your video I've already had a problem with I replaced on my vehicle. The thermostat housing leaked on vacation we barely made it to the repair shop, matter fact we had it towed did not want to overheat the engine. The transmission has been rebuilt, the differential has been rebuilt, all for struts replaced. And here's one for the books, the harmonic balance blew a part, lucky the fan belt could ride on the metal part just enough to safely get us to a shop. Also upper control arm bushings wore out, Ford only supplies it with a new control arm. I got 119,000 miles, and my mechanic says you know after hundred thousand miles you start having trouble, I told him no problem. All these problems I have with my car all happened between 30 and 80,000 miles.

2004 4.0 here. I have 200k+ miles. Issues I have had is the thermostat housing twice, trailing arms twice, EGR valve, front & rear wheel bearings, muffler+rear tailpipe above rear end+ clamp before muffler rusted in pieces. Just did intake gasket, valve cover gaskets, EGR valve, coilpack, wires & plugs. Improved performance now but problem that I still have is rough idle. I am guessing probably a vacuum leak somewhere. I know idler pulley is making noise. Oh and another thing is charging system light flickers on & off & beeping over & over again driving you nuts going down the road. I just seen people talk about the plug on the alternator doesn't make the best of connection so you have to tweak the prongs a lil. I will do that tomorrow. But as for a vacuum leaks have you seen any common issues that I may want to look at for the rough idle?

Thanks for the video, Tim - you played the Exploder's greatest (s)hits! I've had an `03 since new and have had to deal with most of these issues now that it's got 125k on the clock. In fairness, though, it wasn't until the last year or two that I've had to do anything except routine maintenance on it. I'd say they're built to be traded in before 100k, as that seems to be when you need to decide if you want another car payment or the pay-as-it-breaks plan. Being an Exploder owner who wrenches his own ride, I skipped the roscoe and opted for the fatty - my back might hurt and my knuckles may be bloody, but damnit, I'm still laughin. lol

Other issues on the 4.6L V8- Sway bar bushings and end links. Don’t buy MOOG - lasted 3 months. Go with Napa. Radiator, heater hose, electric fan, O2 sensor and wiring. Just to name a few.

I've replaced a few of the thermostat housings. Ha! shift lock solenoids, quite a few stories on those like one towed from another shop where the frustrated mechanic apparently used brute force when it stalled in traffic and broke the whole assembly. (Exploder, isn't that correct? I've been calling them that for years). There is an actual slot in the lower cover where you can push a key up in to release it.

My 97 Mercury Mountaineer with 5.0L engine is a keeper. Check engine light has been on for 5 years, but the manager at Tires Plus told me to ignore it. The odometer has been stuck at 125K miles for 10 years. I only drive ~6K/yr. It takes a 7" round air filter, not the square one. Except for the driver's seat, it's in mint condition.

I have a 97' as well and thats why I'm here but I'm curious to know common issues with our year and model. If you find any or know of any, comment it here and let me know! Trying to keep it in good condition. My odometer stopped reading as well haha!

[@billkrause4585]

I had a lot of problems with warped rotors in the front, but after putting on those High Performance Slotted Rotor that resolved those problems. I do get a noise from the left front wheel when turning it sharply to the left in residential intersections. It might be from rubbing the engine splash pads. I don't know.

[@rodp878]

I bought a used 03 4.0.....and I've had it for 2 years it's nice and drives like new....only thing I've done was change the front wheel hubs.....I'd drive it to California from Florida with no worries.....gotta maintain y'all's vehicle's especially changing the oil on time and replacing oil filter with a good one or the oil passages get gunked up causing oil not to circulate promptly on startup which will give you timing chain noise at start that will eventually break the guide's......but if you already have the noise at start but goes away a short time later......you can hold accelerator to the floor and crank a few times till you get oil pressure then start normally and your timing chain won't slap

[@daveware4117]

You got yourself a solid vehicle especially for work or something to work on. That 302 is still pretty sought after interns of how strong it is and how long it’ll last. I got a 99 with the 5.0 20 years and just under 190k miles still holds strong. I’m thinking to start upgrades the engine and work my way through the truck.

[@ackscratchers6648]

Hey I have a 08 mountaineer. With codes p0171 and p0174. Bank 1 and 2 are lean I suspect a vacuum leak. And I found a very corroded hose to the right of the throttle body going into the manifold do you know what that is called?

[@joshuamoore24_7]

My 1996 Ford explorer Eddie Bauer Edition 4.0 2wd Automatic kept snapping pioneer flexplates. I looked online no hp aftermarket flexplates. A couple years after abandoning the truck I had problems with a different Ford I bought a 2000 Escort SE. The flexplates broke on it also I replaced, then the new one bent. Finally I called Pioneer the flexplates company a couple of times. The flexplates in both vehicles were 1/16" steel. Finally I found out Pioneer doesn't heat treat the flexplates. That's one reason they break easier. So I heat tempered the one I put in the Ford escort and it never broke but the ignition switch in the steering column caught fire and burned the dash up and steering column. Now I am saving up for another vehicle. The third one in six years. I am not buying a Ford next time.

[@adamxenon829]

Did you buy OEM parts?

[@atpdx]

On my 05 the heater hose, the one with the tee that goes back to the rear heater core, ruptured on a hot day. This was sort of a pain to fix because not only did the Ford factory CD rom not mention anything about this hose except that when you're removing the engine you need to take the heater hose out. The Haynes manual had no mention of it either, so I basically just had to unscrew the clamps on the 3 ends of the hose configuration, take the whole thing to AutoZone and find the same guage hose and plastic tee piece and just build a clone of it. There's no replacement part, just get the hose and the tee and make sure your clamps are tight as shit. Another stupid issue is that the duct that directs cabin airflow from defrost position to the front vents is connected to an actuator by a shitty, highly breakable piece of plastic. When this breaks it leaves the duct in a weird position and the vent pressure is heavily reduced. Unless you connect the duct to the actuator by either removing the entire front dash or removing the glove box and squeezing into the side of the dash - you'll have virtually no air blowing out of the vents. A quick fix would be to shove something under the duct to hold it up or down so that there's no air leakage but to really fix it you need to skillfully drill a hole into the duct where the plastic broke off and ziptie that to the actuator.

[@vegasfordguy]

Also about the K&N, from personal experience I don't care for them. I've never had the oil getting onto the MAF before since I don't over oil it. However I have seen micro dust getting through the element. I'd stick with OEM, just my preference and this is for all vehicles.

Changing the fluid on a high milage transmission is a hot lead enema!!! Flushing the trans is even worse! That fresh trans fluid will do soooo much damage to the seals etc that you will have absolute trans failure in 500 to 1000 miles! CONGRATULATIONS!!!

[@moonshadow9178]

Thats an exception,not the rule. These cars are notoriously unreliable

[@STBRetired1]

Apparently they don't have annual vehicle safety and emissions tests required where you're from.

[@JM811Cars]

@@dexterlovejoy2855 that is completely untrue... if you think changing the fluid will cause damage, the transmission is already damaged and is being masked by metal particulates in trashed fluid. If a transmission is maintained and fluid is changed regularly, changing it with high miles won't hurt anything.

[@dexterlovejoy2855]

@@JM811Cars you obviously have never had a high mile transmission. If you've been changing the fluid every 20K, you won't have the adverse effects as much. This is why mechanics will recommend drawing out a quart and adding a quart if you really feel its dark tranny fluid. Even then, just because it's dark doesn't mean it's dirty or burnt. Just discoloration from old seals. It doesn't effect the performance of the fluid. This is where jackasses go full blown idiot and do a fluid change. VERY EXPENSIVE MISTAKE!!! Just because you believe it's ok to do this doesn't make you right!

I have a 2000 Mountaineer and had brake shoes and rotars replaced and on my way home there was a mild dip in the road (65mph) and all of a sudden the front end started shaking like crazy, i de-accelerated and at 50 mph it settled down. I have no idea what is wrong with it. I called my mechanic he said no clue but then called me back and said "DON"T DRIVE IT" have it towed in the morning, so i had it towed the same night to the shop who done the work and he said everything under the front end looks good and everything is tight. Another opinion from the tow truck driver said the tie rod(I have photos of both sides) on the passenger side was in bad shape(my mechanic said)nothing is wrong with my tie rods. He did say the rack & pinion is leaking a little bit but nothing is wrong with it and he said he drove it down the road at 70 mph and there was no shaking. So, for my own peace of mind i am having the inner and outer tie rods replaced, have it aligned and hope for the best. Any idea what you think it may be? Thanks, Ruby
