I have a 2002 Suburban with 190k miles. It hasn't happened very much but after coming off the highway to a stop ill do an easy acceleration and it'll have a rough vibration. Once I let off the accelerator it'll go away. I've checked the u joints and they have no play and the transmission was just rebuilt. I changed the rear end fluid about 5k miles ago before this ever happened and the old fluid was clean. It also vibrates a little at high speed about 70mph and higher. Any help or suggestions would be great thanks.

 

Check transmission, and engine mounts

 

Tires and suspension is a possibility.

 

tires and ujoints are the first place to start and easiest to rule out. the ujoints have no play but did you check for a seized ujoint? to do this remove the driveshaft and move the yolks by hand...everything should move smoothly with no binding.

where do you feel the vibration....driveshafts transmit through the body. front tires through the steering wheel, rear tires through the body.

 

I have brand new tires, I've had the front and rear drive shaft off and checked them. Suspension is all good. I haven't even thought about checking the engine and transmission mounts I'll check there next and left you guys know what I figure out. Thanks for all your help!

 

Its definitely a vibration through the body so I'm assuming it's in the drive trian
