I was thinking of buying a 95 to 2000 era 4runner, thinking toyota is a can't miss.
Found many in my area, mn. All ads mentioned new tires brakes rotors etc.
I thought that unusual so I googled. Found vibration issue.
I've read 100's of complaints from most veh. With 50k to 200k miles. The issue
Seems to cover at least 15yrs. Of 4runners.
Now I know most owners don't do prevent. Maint. Like grease wheel bearings etc.
But this seemed more than that.
A lot of owners had firestone tires. Some replaced more then once. Many went
With diff. Manuf. Name brand ie. Goodyr. Etc. Same prob.
A bad lot of tires from same comp. Maybe but not so many different ones with
Tire separation bulging etc.
What caught me was the severity. These virations are shaking the suspension and
Related parts so much they prematurly wearout and cause accidents.
I wonder about or if toyota went cheap to save money per unit.
I wonder if the spindles and axels and hence their bearings are under sized for the
Weight of the vehicle. If the bearings are cheap and with 16 and 17 inch wheels
And off road tires the road vibrations from the tires wobbles the bearings
Then all the related suspension fails. Wheel hub seals fail which caused brake failure. I wonder if the shocks are undersized for the veh. As well.
These issues are in the tacoma and camery as well.
Those are both much lighter vehs. Then a 4runner and no way are parts
If toyota saves 5cents on 1 part used 4 times in a million or more veh.
You do the math.
Would be interested to know what you find out or your thoughts on my
#161 of 169 virbration issue

I was thinking of buying a 4runner.
I did some googling.
If I had a vibrating veh. I wouldn't drive it much till it got fixed.
The 100's of complaints I've read none were good out comes before accidents.
Normal cars require front wheels be repacked every few yrs or more freq.
Dep. On conditions. If bearings or spindles are worn replace them.
A bigger rig 4runner might be anually or so.
Tires are supposed to be higher qual. Then they were 50yrs ago.
Tire tread separation bulging etc. Not acceptable.
Most front end align. Shops have an electric motor with a
Rubber wheel attached.
They jack your car up wheels off the ground and use the elecric motor
To spin your wheels up to speed. If you have wheel issues it should find it.
Dyno shops can test the veh. Performance at all speeds with the hood up
And drive wheels spinning under all types of loads.
If you have tires with a large counter weight or combination of,
Over 1.5 to 2.0 oz. Get another tire there is probably a defect in it.
I want to get a toyota but not with these serious issues
If I helped your issue post what you tried. Maybe it will sway me

you really need to check your u-joint. I have the same vibration problem at 70mph. visual looking at the u-joint and shaking the drive shaft, but seem to look and feel tight and a few months of continue driving I heard scrapting noise - come and go. I re-check and notice that the u-joint has a bad metal seal ( near the transmission output side. I replaced it, but the vibration was still there, but at 60 mph this time. I took it for a wheel alignment because it was drifting and my new tire is balling unevenly. It still vibrate after the alignment. I was upset and decided to change the rear u-join bearing near the rear differential out too. This time I check to make sure that my shaft and joint are assemble correctly and it was. I also decided to change the rear differential fluid this time. I used 80w90 gear oil . The old fluid look dark compare to the new. I geased the end of spline shaft and it's mating part well and connected it back to the transmission and the other end to the rear differential. This is my wife car. I didn't test drive it after a week I re-assemble the shaft. She did most of the driving and she does not take the vehicle on the freeway. if she did, she wouldn't know anything even if the tire come off. I have re-built the engine twice - thanks to her. Anyway, I took it on the freeway today and notice that the vibration was gone. i tested at 80mph and no vibration.
Conclusion: changed u-joints (front and rear), gear fluid did it.
I fixed 4runner error code 71 (egr system check engine) It was annoying, but I finally fixed it by replacing the modulador. A stupid piece of round plastice device with vacumm port and cost almost $300 at the dealer, but I stoleone from one of the vehicle at the junk way and it worked.

I am having the same issue. Did replacing the U joint and bearing fix the issue?

Did you check rear driveline for straight and balance after accident if not I would check there!
#165 of 169 Vibe when coasting @ fwy speeds
Jul 08, 2013 (6:28 pm)
2000 4Runner SR5 2wd
Original owner, 200k miles
Brakes done a month ago
Just replaced all 4 tires + struts & shocks
Goodrich Rugged Trail T/A P265/70R16
Had serious vibe problems at 60 > 80 before this work.
Mostly went away but first fwy speeds today and still have have a pretty noticeable vibe at the same speeds when I coast.
From what I've read here it sounds like my first step is to have the U joints checked.
Any other recommendations?

Determine the where the vibration is coming from. If you feel it at the front, check your tire balance, re- balance if neccessary. Check your control arm bushing and steering linkage. If it come from under where driver is then i would say it is the universal joint. You have to remove to inspect or replace. When it on the truck it feel tight because it lock to the rear differential and the transmission.

If the vibration is only occurring when you coast and not when accelerating slightly, then the problem is very likely U joints. The drive angle of the rear axle changes depending on how much power you put through the axle. Any change in power changes the pinion angle (relative to the driveshaft) and if the U joints are worn, they will not turn smoothly - hence the vibration.
BTW, tire and other wheel end related vibrations will be there no matter what you do to the accelerator.

Thanks much for the quick replies!
I'll check the areas you recommend

I have an 07 4Runner, Limited, V6, 89,000 miles on it - the vehicle doesn't have ANY problem, no vibrations, no buzzing. The only thing I would change is that I don't like the leather seats and I wish I had got the V8 because I want to buy a small camper.
