Alright here's the deal I have an 08 gsr with 51k. My rear differential locked up so I ended up buying a used one. I installed it and brought it to dealer and they bled the whole system now when I'm driving and hammer on the gas the whole car vibrates but under normal acceleration it doesn't vibrate at all. It also vibrates even worse when I get about 60-65 mph. The tires were mounted and balanced two weeks before all of this and none of this happened. I tried turning drive shaft in all four bolt patterns and still does it, all the joints are stiff. If anyone has any clue as to where I should go from here that be a lot of help .

 

Bump anyone
