Cadillac CTS-V - Noise in rear question

Hey guys I just picked up an '04 V and was wondering what this noise could be. When shifting I heard a thump coming from the rear. Am I not shifting correctly, or could it be something else. Car has 80k on the clock and is bone stock. Thanks!

You need a new differential bushing.

It's best to go aftermarket because the new OEM bushings don't last very long.

Order the bushing and block from creative steel and you should be good for a while.

The install sucks, but its worth it and itll cure your problem. I just did it. Part of it is how you shift as well though. With the CS bushing in there, now I can hear the bolt holding the bushing in place make a click sound if the shifts arent perfect. Its part of the V character.
