I had a 3" lift put on my 02 Taco and now I am getting a vibrating feeling when my truck is decelerating to about 25mph. I think it might be my drive shaft going to the rear diff. Is this caused by the angle of the drive shaft? If it is how would I correct the angle to eliminate the vibrations. I have had an alignment and I cannot think of any other reason for the vibrations other than drive shaft angles. Any help would be most appreciative.

 

I am having the same problem so hopefully someone will help us out.

 

Did you install a diff spacer along with the lift? Do you see much grease splatter coming out of your CV boots?

 

I have a prerunner so no I did not install a diff drop. I am pretty sure it is comong from the rear.

 

did you try lubricating the driveshaft?

 

I do have a diff drop kit installed and I did grease the drive shaft very well. I have not noticed any grease splatter coming from the cv boots.

 

You may have to shim the the rear to get the proper pinion angle. http://www.4x4wire.com/toyota/tech/driveline/
