Vibration at 120km's.

[Bilzner]

Hello fellow Chevy owners, Awesome club!.

I have a 1995 GMC Yukon. I just recently got both U-Joints and rear and front seals replaced because of a leak. I thought that this would fix the problem of vibration, but it didn't work. I took the truck back and they balanced the drive shaft which seemed to work a little better although a vibration remains at the speed of 120 km's per hour. I would overlook this vibration but it is horribly annoying.

Could anyone help me out with this? suggestions? What other things should I look at? Please help, any reply would be humbly appreciated.

A fellow Yukon enthusiast.

sorry, too lazy to look that up in MPH. :-)

Was about to say that you shouldn't expect it to be smooth going 120!

Did you do any gear swaps? Usually a swap to 3:73 or 4:10 will require new drive shafts. Does it feel like a drivetrain issue, or could it be in the front end?

Have you looked into things like wheels and tires? Alignment, etc?
