2004-2007 Cadillac CTS-V General Discussion Discussion, Differential Install in Cadillac CTS-V Series Forum - 2004 - 2007; So I am going to replace my diff soon and I am wondering if it is an easy swap? I ...
The diff swap really isn't that big of a deal. Take your time if its the first time doing it. I did mine about 2 weeks ago and it would have been done in a day if I hadn't run into a couple headaches. Listed to Rand49er and make sure to have the write-up on hand. In the write up he mentions a 21mm Gearwrench. INVALUABLE! Also, I overlooked the breather valve which is the freakin reason it took me two days to do the install. The local dealers were closed and its a dealer only item.
Did the swap in my driveway with the car on jackstands. No "special" tools really to speak of.
Very straight forward. You don't need to remove the upper ball joints to get the axles out of the hubs and if you can't find a 21mm gear wrench, get a 13/16 gear wrench as it's essentially the same size but easier to find. I've had axles out several times and removed my diff once. I could do it in about 4 hours now, while laying on a garage floor.
My diff has developed clunk on top of clunk, and is whining loud. So I pulled the trigger and I am a new proud owner of Jims steel differential
No more clunk, no more worries, no more waiting for someone to come up with a solution that works like factory.
ohhhh, and no more money!
Wow, the Steel Diff.
I could have used one of those.
I just had my diff completely rebuilt by RPM Motors because it had a clutch pack problem and then somehow developed a whine after the diff bushing install.
Definetly let us know how that Steel Diff turns out.
Can it really eliminate all clunking?
