Anyone know how hot a rear axle can get? The cover on that 3.73/posi/disc axle is pretty rusted, and I'll swap on my chrome one from my current axle.

Problem is, my current cover doesn't have a magnet, and I didn't really care- but this other axle has a posi. I want to take the magnet off of the posi's cover, and put it on mine. I imagine the magnet won't move much, but GM puts that epoxy around the magnet anyway. I'd like to do the same (epoxy it on my current cover)- any suggestions on epoxy?

I'm thinking of using JB Weld- sound good? Or would the axle get too hot? I mean the stuff can fix an engine block, would the axle get hotter than that?

Or better yet, is there a magnetic fill plug available for the diff? Or wouldn't that cut it (too small of a magnet)?

Thanks!

The rear shouldn't get any hotter than 250º, and should usually stay alot cooler than that.

There's no particular reason why the magnet has to be in or on the cover. Why not just get a big one, and stick it to the bottom of the housing just inside of the cover? A good strong one would surely stay put there.

Thanks, I didn't think about that angle. I suppose I have to search now for a strong magnet! Have you seen those ones from Eastwood Company? They make long rectangle magnets, meant to drop into your oil filter. I think they sell a pack of 6 for $10.. those might not be strong enough to hold tho. Guess I have to search the internet for magnets!
