ok i have a 2000 Limited Tahoe. I have a shaking in the rear of the Tahoe. i have put new wheels and tires, new shocks and it is still shaking. Nobody can tell me what the problem is? So any help would be great!!!

Thanks

 

When does it shake?

 

It starts around 50. it is very little but when you get to 60 it gets worse and then at 70 it bad!!! I mean so bad its almost like the truck is going to come apart.

 

Get that thing up on a Floor Jack (single point of lift under diff) and put it in gear.
Look at the wheels (round/wobble/balance) check the drive shaft for straight and maybe a clip is missing out of the rear U-Joint.

 

Is it worse when you accelerate?

 

i put it up on a life today and wheels are walking a little on the rear tires? It only shakes bad at 60-70.

 

rear u joint is fine and tight. The tires walk like i said. The drive shaft looks good.

 

What do you mean by "walk" ?

 

they are wobbling a little but not bad.
