Hey Gang - '99 FRC track car, stock rear differential. I've got a leaking left axle seal, and was planning on simply replacing the seal - but have found up/down play on stub as it goes into the left side cover. If I take the cover off, is there a bearing / bushing I can replace to make the play go away - or am I looking at a deeper issue where the diff will need to come out and be taken apart?

Brief video of play:

I've got a race this coming Sat & Sun and am hoping there is a reasonably easy fix, as I've got other systems apart for maintenance as it is.

Pull the axle and look at it, drain the fluid and look for metal.

Found this awesome, long-running thread:

One of the first couple pictures shows a needle bearing in the main housing that supports the left side CV shaft. I'm guessing that if that was worn I'd get some slop at the seal. I wonder how much corresponding wear there would be on the shaft...

It may require some exploration - but, (to refine the original question) does anyone know if this needle bearing can be changed in the car?
