Greetings fellow caddy fans, I’ve been reading on forums for a couple of years and finally decided to jump in. Great info here has helped me keep my cts running like a champ. I had the dreaded clunk/thump from my differential until last weekend when I put in a rev shift bushing, drives like it did when I bought it and I am a happy man once again(although a certain neighborhood kid in a Lexus gs400 is not). Next I will be changing the driveshaft center support bearing and guibos to get rid of the last 5% driveline lash that the diff bushing didn’t fix. I am also looking at 1st gen CTS-Vs now and hopefully will be stepping up to the big boys soon. Thanks to all of you for being here and being so generous with your knowledge and experience.
