hmm... I guess I just need to do some looking around.

This has been very helpful everyone, I needed a little real world experience here. unfortunately the only trailer place remotely local to me I *hate* to deal with due to their markup.. I mean, they had a GN ball I needed in stock for $250 but I ordered it from an RV place for $95 and waited a week, same thing for trailer fenders, I would hate to see their cost for an axle

looks like theres some deals on 7000-7500 axles for around 400
on the other hand I could buy and strip 5200lb ones from utility trailers.. there plentiful in this area.
more MH axles go for $75 ea. but I would rather try n do it right.

have some thinking to do on it I guess.

 

Check out this axle tech from Bill Vista on Pirate4x4. He may have some answers as to how you can repair or rebuild your existing axles. Lots of part numbers.

The spindles on 2 of the 3 axles are stripped.. thats the issue, so they need replacing.

Then, Dexter and others sell hub kits. You can re-make the axles if you like. I expect that doing so will cost more than replacements, however.
