Re: `96 ZR2 - bad bearing or CV
You have to replace the whole sealed assembly, much like a FWD car, usually $100 and up each side. It sounds like a Cv or other drivetrain problem, though. I've never priced a CV shaft for a ZR-2, but probably they're more expensive than an S-10 one($75 reman Limited lifetime warr @ AutoZone). Usually its cheaper, and less labor-intensive to just replace the whole assembly than to try and replace 1 joint or 1 boot, and get everything back in the same place so it'll be balanced. I hope that its just something minor, thats easy to fix! Good luck!
