Just swap the cv buckets from driver's side to passenger side and vis versa. Your axles should be ok.

what type of noise?

scraping? clunking?

I'm getting a scraping/creaking/light-grinding noise from my rear halfshafts (sounds like). Only at neutral throttle. Under positive or negative load, no noise. Cornering loads subdue the noise as well. Almost sounds like a halfshaft lightly grinding on a sway bar.

It doesn't make the noise all the time, but seems to be doing it more so here lately (despite my hopes of it going away!).

I'll be bringing the car into my work to have a look in a bit, anything in particular I should be looking for?

Thanks!

Reminds me of the sound my wheel bearings made when they started going bad. Scraping sound that would go away in corners...it turned into a screetch after I ignored it for a couple more weeks.

Yea, Negcamber, "grinding" sounds more like wheel bearings than CV joints.

Thanks for the input!

I got under the car earlier this evening, and it seems like it might be diff output bearings (I made another thread about it)

I could grab the inner cv joint and move it up and down a bit, thought it must be the CV, but then I noticed that the diff output flange moving relative to the diff, up/down maybe ~.015" and visibly wiggling (top of flange in/out, bottom out/in). Both sides, left a little more.

I'll investigate wheel bearings tomorrow. When I tried to rock the wheels back when I first noticed the scrapy noises last month there didn't seem to be any play.

I drive like a grandma on the street, but of course drove the bejeezus out of it at the track this year. 10 track days worth.

Thanks again, additional thoughts/commentary/advice appreciated!
