#161 of 164 virbration issue
Oct 07, 2010 (11:46 am)
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?
