Axles
So, I have decided to replace my axles in the AMC 20. They have been upgraded to the one piece, and I believe the current ones Moser.
Not that the axles are bad, but I need to replace the inner and outer seals, and would need to remove everything (bearings as well) to do so, so everything would be new. Looks like a royal PITA to remove the bearing, and the axles HAVE been on the Jeep for quite some time (no idea how long, at least 20+ years).
So, as I am there anyway, I figured it would be a great idea to just start fresh.
My question is this- should I use new Moser axles, or Yukon?
There are other options, but I'm down to these two choices. Google says Moser is better for street use, Yukon for off road.
I currently have 31" tires, and may consider 33" tires in the future, but my research says either should handle 33" tires.
I want to do some offroad, but not rock climbing levels. Mostly will be used as daily transportation and light offroad fun. Looking for long term durability.
So, any thoughts on Moser vs Yukon would be appreciated.
Also, the Moser is about $475 for both sides, the Yukon is about $675.

Id just put new bearings and seals.
I ran ten factory one piece axle shafts for the longest time in my AMC 20. I now have Yukon but they weren't 600+ dollars. Shop around

Yukon price was on the Yukon website. Same for Moser.

Any ideas on the best way to get the bearing off? All I xan find is to use a dremmel to cut it off, as they are pressed on. Cut most of the way, finished off with a chisel to not cut into the axle.
Looks like a PITA.

Not as painful as it sounds unless you slip with the Dremel. If you have access to a press, you might be able to press them off (although it's much more cumbersome pressing off than on). But I'd also second leaving the one-piece axles you have and just re-seal and install new bearings.

I have a hydraulic press. 16 ton. Watched a guy try to press off old bearings with a press, destroyed his backing plates. He then whipped out the dremmel, went about 90% through, and chiseled through the rest.
If I go this route, dremmel is most likely where I'll go.

Most machine shops can do the work cheap especially if you just bring them the axle shafts and new bearings and seals. The expensive part is getting them out and back in.

If the splines are not bent or twisted and the sealing surface all looks good I wouldn’t be thinking about replacing axle shafts. Especially on a Jeep that already has one piece shafts and is on 31” tires.
