'90 XJ Rear with "issues" - What is the best option?

I have a '90 XJ that has what I think is a bad bearing (low drone sound).  I am trying to figure the best option.  I have an '89 XJ that I am parting out for the repairs, but the '90 has ABS brakes.  Here are the options as I see it....

1.  Repair the existing rear
2.  Replace the rear with the one from the '89 and either disable the ABS or retrofit the ABS (if possible).  Can I do either?
3.  Replace with "better axle".  What would be a good fit without alot of headache?

I don't have a ton of experience with swapping a rear, but I can work thru it.  I also have a pretty good salvage yard for upgrades.

The Jeep is stock now, but I have a 4.5 lift in the wings after I get it mechanically sound.

Any advise??

if you wheel your jeep i wouldnt even mess with keeping the abs, you dont want your brakes to pulse on a steep slick hill

Any articles or tips on getting rid of the ABS?  That is actually my prefered route to go.  If this is the case, should I swap the other Dana for the '89?
