Rear disc brake conversions?
Ok I am well aware you can buy a tremendously overpriced kit to achieve disc brakes on an XJ...also aware that with some work you can use ZJ d35 disc brakes on an 8.25...but i was at work the other day and had a Liberty on my lift for an oil change/ multi-point inspection and i realized that they have an 8.25 with disc brakes...
Can we use disc brakes off a liberty and swap it right onto our xj's???

I saw a writeup on that a while back, can't remember where. I bet a Google search would turn it up though. It looked like an easy enough swap.

Liberty disk brakes are a direct swap to a factory 8.25. It`s the same axle except how it`s sprung. you do need the 2003 and newer. I checked on parts from the dealer and it was more than I paid for my 2000 XJ. not may in the wreckers yet but the ones I have found will not part out the brakes from the whole axle. Soooo.... i found a D35 ZJ with disc brakes for $50. I think grinding out the backing plate with a dremel tool is worth $500 that they want for the whole axle.

I did the swap from a grand cherokee... took me 10 minutes to "modify" the backing plates. Super easy swap. And, parts are a dime a dozen at pull-a-parts

Im in the process of doing the conversion 
stupid diff gears wouldnt spin today so got nothing accomplished...Should finish 2m...Got my parts off a d35 grand cherokee tho...I believe years 94-98? Cheaper this route imo....all you need is 10$ backing plate from JY and local parts store sells rotors for 25$ and calipers 28$ each brand new liftetime warranty !
