Rear end clunking

[UKXK189]

I think my 10 bolt is rapidly failing on me. I get alot of clunking from the rear, not just on turns anymore, but also straightline, under acceleration and coasting. Am I correct in assuming it's the 10 bolt, or could it be something else?

The 10 bolts are generally junk, so it wouldn't be surprising if yours was dying

I'd check your u-joints, torque arm, rear end bushings, & tranny mount (if it's an M6), before throwing in the towel on the rear end.

Shop just called, it was bad pinion bearings, and some broken gear teeth. They say it's all fixed and there is no more rear end noise, if that's true, not bad for 100 bucks.
