Should you buy a 4th Gen Toyota 4Runner? 2003-2009 Common Problems

A Toyota Master Diagnostic Technician shares common problems that you should look for when buying or owning a 4th generation Toyota 4Runner between 2003-2009 model years.
So Should you buy a 4th Gen Toyota 4Runner? In this video We'll go over some of the common issues I see with this awesome truck that you should know about if you own one or looking to buy one.
Here are some helpful videos for Toyota 4Runner owners :

• Toyota Trucks Sealed T...
5th Generation 4Runner common problems:
• 2010-2020 Toyota 4Runn...
Toyota 4runner Technical Review Series:
• 4Runner Technical Review
We'll follow my channel's format for common problems broken into sections.
First we'll cover some common issues with the engine. The 4Runner in this generation had 2 possible engine options in most markets. The 4.0L 1GR-FE V6 and the 4.7L 2UZ-FE V8 engine. Although those engines are solid options they do have some issues that are common.
Then the Transmission of the 4Runner. 2 Possible options, The 4 speed and the 5 speed. Both are very solid transmissions with very few minor issues. Make sure you replace your 4th generation 4Runner transmission fluid every 60,000 miles or 6 years so you won't have to worry about the transmission filter.
I'll also cover common issues with the 4WD system. Make sure you use your 4WD frequently as instructed by the owner's manual. This alone will prevent many of the issues.
I'll also cover items on Chassis, Body and Electrical. Including issues with suspension and a common knocking noise that is very simple and inexpensive to fix. Brakes are generally good on this truck however rust does affect them which is a theme with this truck.
Lastly we'll have the frame rust conversation. This is possibly the biggest problem with this truck. One that can basically mechanically total this truck. Be very careful when shopping for one. Do NOT buy a 4runner that's rusty. And always under coat the frame to protect it from rust.

I have a 2004 Toyota 4-Runner 4.7 L V8 with over 380,000 miles. I have always serviced it at 5-8K miles and always used full synthetic oil. Changed the timing belt and ATF per schedule. Only had one minor problem in18 years and had to replace the passenger side CV joint. A great AWD vehicle with 4WD features. Best vehicle I've ever owned!

[@gonefishing5434]

I have a 2004 Sport Edition with the 4.7 V8 and have not had any issues. I am the original owner and have run Mobil One 5-30 full synthetic with 3-4 K mile oil changes or every 6 months. Last few years only put maybe 2 K miles per year for fishing pulling a 3K lb boat. 181,000 miles 90% Freeway. Live in the wet side of Oregon and salt is not an issue. Also, time belts as scheduled. I will never sell this rig. 71 years old and it will last me until I make the final transition. I love this rig! Drives tight, not one rattle. I ONLY buy Toyota products since the late 70's

I've spent less than $500 on repairs in 17 years, because I follow ALL service schedules and never abuse it. I love your channel. Thanks for all you've helped us with.

[@trentonclark3689]

Adding to it: If you end up having to replace front calipers, go with 5th gen calipers (less prone to seizing up). For this, you will have to have 17" wheels to clear the calipers. Also, if having to replace CV axles, consider buying used OEM axles from a 5th gen 4runner or a GX460 (can get some nice used ones with ultra low miles on them for fairly cheap) - the newer CV axles also have an extra rib or two on the engine side that allows more flex and is less prone to ripping. Look out for leaks from the transfer case actuator as well (black box on the back/bottom of the transfer case) - transfer case has to be removed and split, but the little o-ring that is the culprit is only $6. Just do your research if you are a DIYer and these 4th gens are pretty straightforward to diagnose and maintain!

Change your rear differential breather valve, they rust and collect dirt easily causing them to not function as well which can cause your rear axle seals to blow out from pressure building up. I change mine every few years, takes two seconds and costs maybe $7 top!

[@thaloszapispapos715]

I have a coworker who owned a 2006 4Runner 4.0L V6 up until 2019. The only reason my coworker got rid of it is due to suspension and water pump issues. My coworker thought the estimate from the dealer and the local repair shop was sky high fix. The SUV was traded in for a new RX 350. After a few days of driving it went to the Lexus dealer asking for the 4runner back and was told the SUV was in the process of being sold. To this day the coworker still lives with the remorse of trading in the 4Runner and mentioned to me it would've been cheaper to repair it instead of making monthly payments now.

[@jamesrebbechi4471]

Ouch !!! Unfortunately we car people can get led by our emotions and temporary self affirming biases at the time and make crap later regretful decisions. I still regret & miss my very first car, a 1967 HR Holden wagon my grandparents toiled hard and long to pay for and look after for 15 years before proudly handing to me which I stupidly traded on a V8 Torana SLR and debt only 12 months later.

As always, amazing video. Our family's 07 4Runner has 355,000 km on it. The one thing I like about these generation 4runners is that you can run them full time four-wheel drive because they have torsen differentials (on all trim levels). 5th generation 4runners only have torsen differentials on the limited models, the only trim level with full time 4wd. We also have a GX470 with 212,000 miles... They're absolutely incredible

[@russmt4181]

I took my 2006 with the 4.7 v8 and 220,000 miles to my local dealer in billings and told the service manager I wanted timing belt, water pump, and tensioner and all idlers replaced. I never asked him to cut corners, told him I wanted it done right. I show up and all they changed was the belt and pump. I asked why and I was told the tech thought they looked "pretty good" . I told him it damn well better last another 100,000 miles. If I wanted a shade tree job done I would have taken it to a shade tree shop and paid a lot less.

[@amiddle3317]

Wow, this video is spot on! I have an 06 4runner v6 4wd with 210k and finally there is a detailed video about these trucks! Another thing to note: I have the limited with the 18” alloy wheels. I also live in Chicago. 16 years of road salt destroyed these wheels. They cracked and rusted badly, and wouldn’t hold air for more than two days. Finally got new wheels and life is good again. Just like all other 4runner rust problems, wash the salt off the frame as soon as possible when it gets above freezing. And DON’T FORGET THE WHEELS

I have a 2008 Sport Edition 4WD Runner and whenever I come to a stop and release the brake to drive again I get a clunk and bump feeling coming from under the truck… I replaced the driveshaft u-joints and greased them and the transmission fluid is changed according to the dealers suggestions… What could be causing this?

I've had 4 of these all 2003...nothing but tires brakes batteries and oil changes and over 300k on each and still going!

No headgasket issues?

Thank you for sharing your wealth of knowledge with us. I recently purchased a 2003 v8 4runner limited. It runs great and moves through snow like a champ. I live in a rusty area, and the bottom has been undercoated in the past but most of the frame seems solid (after a tap test), however the notorious rust spot behind the second crossmember on one side is rotted out, side and bottom, should I repair it or is it a waste of time? (I plan to use a lanolin based oil undercoating going forward).

Hi! You could reinforce it if that’s the only spot

Love the video just bought a 2007 V8

Love your channel

[@BobMarley-pm1xb]

Great review. Just subbed and GBU you and yours too

[@michaelmagaruh7767]

Love your videos, watched before buying my 4Runner. I have a 2007 T4R SE V8, getting a P0420 code. Starting with the O2 sensors, do you know if this will fix it or will I have to replace the catalytic converter? Thanks!

Love the red on that 4th gen

[@BassMan-wr3lq]

Yours is CLEAN 👌 honestly I'd be down to buy it a year from now

My sisters 08 with v6 developed a weird problem. Trans fluid was wicking through the harness and contaminated the drivers side AFR sensor. There was trans fluid in the AFR connector and in the connecors at the PCM. Had to take the pan off and replace the harness in the transmission. Also had the sway bar noises but unfortunately even with heat and penetrant spray, still broke one of tbe welded nuts in the frame. That turned into a fun time. Also replaced many front calipers and the line that connects to them. Yes its a salt belt truck😃

great video, coming from an '07 owner I learned a lot

My mom had a 2007 4runner sr5 4x4 and she has had it since 2007, never had one problem besides maintenance stuff like ball joints, oil, regular fluids, and the seals for all the doors started leaking so we replaced that, we lived in Arkansas and the road is rough, you have huge boulders sticking out, huge pot holes, creeks and everything, we were rough on it, im suprised it lasted, her 2014 rav4 tire fell off on that road lmfao. The 4runner did good, never had bad issues.

That's the sad part of of here in Northern Indiana. Highway crews are very salt happy in the winter and I have seen soooo many body on frame vehicles that are mechanically sound and otherwise pristine condition that have to be parted out because the frames are rotted to the point they are no longer safe from all the corrosive salt. I really wish Toyota never got rid of the V8 in the 4Runner, understand why they did, but it really made it and even more capable vehicle.

[@itsme6026]

When you own a body on frame vehicle you really have to Maintain it. That means washing off the salt as early as possible in the spring. Inspect, clean off rust, and coat underside with POR15. Most drivers care only for their paint & hardly look under. It’s called neglect

[@steved0603]

That's, AMD, were now seriously considering an '08 we found that's a lifelong Southern vehicle, one owner and zero accidents. Good to know that's one of the better years! Love the ending, as that's something I would do, too. 😅🤣😂

Thank you and God bless and keep you too.
