Ok so my 04 Rubicon rear axle is leaking at the drivers side seal and the yoke mechanic wants 125 just to do the axle seal ... I can do the yoke but dont have a press for the axle shaft bearing and ring... I've been told that the seal will wear a groove in the shaft and the new seal will leak ...is this true and should i replace the shaft as it has 315000 miles... rearend was rebuilt 4 months ago and been leaking ever since... had words with the shop so I cant take it back there

Try sliding the axle shaft out and smearing a thin layer of Mopar RTV, Permatex Gear Oil RTV, or Permatex Ultra Black RTV (in that order) around the outer edge of the seal. Clean the opening to the axle tube where the seal seats before sliding things back together.

If you have been considering upgrading to chromoly shafts, the shafts already come with pressed on bearings and seals. Not cheap though, but one of the easiest upgrades to do

Where would I get the shaft as extreme terain says theirs is just the shaft without bearings or seal or flange ...has to be purchased as a kit seperately

These would have the bearings and seals, and are considered to be a very high quality shaft by many site users:
I bought and installed these and it was relatively straightforward. Hardest part was reassembling the parking brakes

Here is a moderately cheaper brand that also has fans on this site:
(I have no experience with these myself)

Revolution Gear axle shaft kits come pre-assembled, everything pressed into place, and ready to install.

But for now, yes the RTV should be uncured for the above suggestion.

Guessing that's per side
