I am bumping this thread as my clunk is getting worse over time. Its getting to a point where I wince every time I hear it because I am expecting something from my car to be laying in the road.

For those that have replaced said bearing, how has this worked for you?

Man I had everything changed on mine except the drive shaft. New diff, all mounts and bearing. Even the motor mounts! Still thumped and cluncked terrible. If I lifted some when shifting(smg) it would help.

Is there anyway to check the CSB without removing everything?

I dont think so. The heat shield is covering about 90% of the driveshaft and its components. You can visually inspect the Guibo/CV joint of the driveshaft but you would need to remove the heat shield to be able to see the U joint/CSB

Mine has a low frequency subwoofer like thump if I'm in 1st gear and push in the clutch pedal quickly. Then it thumps again as I let it out and it loads the driveline again. Does this sound like CSB or something else?

Anyone in the Orlando area want to help me diagnose it? I haven't had much faith in repair shops lately.

Just had the car looked at on a lift and the front diff bushing is bad. It's soft as jello. Can't wait to get it fixed.

I just replaced Diff and diff mounts, entire brand new drive shaft(comes with center bearing), and flex disc. Pulled out of the shop and sure enough clunkedy clunk clunk.

My clunk was ridiculous before i changed everything now it is moderate. You probably have something worn.
