Ok, the place where I took my X28 to get a gear swap said that everything went well and sounds good, but he said that there is a vibration now around 80-90mph. I bought a new set of richmonds 3.73 and he purchased a new install kit with new bearings and races. What could be the problem? I need advice before I go to get it, all help will be greatly appreciated!!!!!!:soapbox

take it back, show them.

Dunno if you have a LT1 or LS1, could be the drive shaft, or u joints, but since the rear was just touched, I would speak to the installer 1st, and dont wait.

I haven't even picked it up yet, what could be the problems, he just did a gear swap.

Check u joints on the DS an balance of unit, maybe even a tire could be out of round.

there are alot of things it could be, but im trying to keep it in perspective.
