He's got a lot of issues with it. It's making constant noise and "banging" when cornering, and he's been told repairs will cost $2,500.00 (a '94 Rodeo is only worth about $3,200 or so). I actually don't know all the details, but he couldn't explain it well because he doesn't do a lot much mechanically. Since the problem seems to be with the diff itself I can't imagine I can fix it.

I did tell him he should try some other shops, since most shops just look up Isuzu part numbers and price a job with those horrendous prices instead of looking up generic D44 parts (been there before) but he's turning this Rodeo into his 3rd vehicle/camping/off-roading toy, so he does want to go as cheap as possible.

An axle from pull-n-save (if they happen to have a Rodeo -- haven't seen many) is only like $52 and you can check the condition of the car it came off of.

Although Curtis did point out some good issues, an axle is something I've never worried about going to a junk yard for.
