Drive shaft u-joint: vibration still not fixed?
The vehicle: 3rd Gen, '99 SR5
Mileage: 90K
The Problem: Vibration when going freeway speeds; 50+ mph (feels like its driving over a washboard)
Diagnosis: Worn front U-Joint
The Fix: Replaced front U-joint
I've recently had some serious vibration coming from my Runner, most noticeably from the drive train. I had my mechanic look the truck over, and determined that the front u-joint was bad. I had it replaced, but after taking the vehicle back onto the freeway on the ride home, there is still a slight vibration present. Not as noticeable, but still present. I will be taking it back in tommorrow, but i was hoping I could get some ideas as to what else I should have him look at (or perhaps i should have a dealer look it over instead?). Any help appreciated!

Make sure the driveshaft is put back on the same orientation before removal. I had the same thing happen to me after I installed my rear air locker. Found out that the driveshafts are balanced and should be installed exactly prior to removal.
