`96 ZR2 - bad bearing or CV

I noticed a clunking sound in my `96 ZR2 a little while back when making sharp turns. I think it is either a bad front wheel bearing or possibly a CV joint going out.

Is it possible to change just the wheel bearings (like on older Chevys), or do you have to replace a whole sealed 'bearing assembly' that costs mucho $$$?

When replacing a CV joint, does the whole half shaft from the front differential to wheel has to be replaced?

Hopefully it's just a loose shock or something else minor, but I'll know for sure after I do an inspection this weekend.

Thanks for any help - this IFS stuff is way different from what I'm use to working on.

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!

Re: `96 ZR2 - bad bearing or CV

Well, I checked it out a little bit this past weekend. I don't think it's a loose shock and when I grabbed onto the CV joint and gave it a few good yanks, it still felt pretty tight (no play in the u-joint). It was getting dark and I didn't have time to jack up the front end to spin the wheel to see if a bearing is coming apart.

I'm going to tear into it this week some time - I REALLY hope it's not anything major, but I have that nagging feeling that it's a bad bearing... I hope I'm wrong!
