It is possible to get the u-joint replaced by a good drive line shop. I had mine replaced about a year ago. I needed a new carrier bearing, and it turned out that the u-joint was bad. They replaced the joint, carrier bearing and mount, and balanced the shaft for about $220? I had already replace my flex discs with the original German made discs, so I did not have to replace them. I had prior issues with the Dorman discs, but it may have been due to the u-joint/carrier bearing issue. The German made discs seemed like they had better reinforcement around the bolt holes than the Dorman units, but they are about 100 instead of the 65 for the Dorman units. I believe the German units are what GM is selling now.
You will also want to check the pilot bushings on each end of the shaft. They also probably contributed to the short life of the Dorman discs as well.

 

Thank you so much! When a simple differential seal turned into a carrier bearing and drive shaft coupler replacement, I got scared. I never have worked on driveshafts.. I got the shaft out and was worried I couldn't do it, almost gave into towing it to a shop. I have new found confidence.

My caddy will be on the road again soon.

Hi.
I've an 2005 Cadillac SRX AWD and I search the part number for the drive shaft carrier bearing.
But it's not easy. Impossible to find on websites...
Can you help me ? Maybe it's the same for CTS, STS, SRX ?

Thanks.

 

I installed new carrier barring I didn't mark the driveshaft where the 2 come apart I put everything back together and now its vibrating around 30mph what should I do any help would be greatly appreciated

Assuming the vibration is coming from the union between the shaft and differential, you could disconnect it and rotate the unit one bolt CW or CCW (and take notes on which way you moved, marking the new config with a paint pen). Then retest. If the vibration is gone you are finished. If not, repeat (and mark the new location each time) until it goes away. The repeated markings will tell you which orientations you already tested, in case something disrupts you and you forget (been there!)

 

Great writeup! Replace that Center support bearing, both Driveshaft couplers, Rear differential front bushing and top off the Transmission fluid. Then your clunk will be gone!
