New Caprice - Discussion forums

Just got a 2012 9C3 V6 car on GovDeals. Nice interior, a little rough on the outside. Only disappointment is a mysterious clunk in the rear end on step-off. Might be good excuse to get a LSD installed. Third zeta car after an SS and a G8. They just go down the road so well.

Welcome!

Welcome! Post some pics. First time I've heard of a 9c3 with a V6.

Maybe it's your driveshaft?! U-Joints are cheaper than a rear end. I have a factory 2013 LSD (2.93) with less than 60K miles I'd sell for 100 bucks. I put in a 3.27 from a Camaro. Either way, enjoy! These are great "rides".
Welcome and enjoy the incredibly deep resources available on this forum!

The V-6 Caprices use a smaller flange on the pinion than the V-8’s. You will need to measure what have and make sure you are getting the correct differential if it is the culprit. The u-joint is staked in and I don’t think it is replaceable by the average mechanic shop. Should be able to check for slop at the u-joint to eliminate it as the cause.

Hey All, Thanks for the replies. It was the carrier bearing on the drive shaft. Mystery solved

Thank you for posting the fix. Folks on Facebook aren’t good about posting the fix.
