This is my first time making a post on this site.  I have a work in progress 85 CJ-7 with a beefed up 350 on 33". The axles are stock AMC 20 and Dana 30 wide track. I recently blew out the rear end and am looking to upgrade.  I came accross some fairly new front and rear 44s off a wrecked TJ Rubicon for a great price. They include rotors and calipers as well.

My questions are as follows: (Please feel free to answer anything you can; or add suggestions, I am open to anything)

1) Will this be a fairly clean swap other than modifying mounting brackets and suspension tabs?

2) Will the TJ 44s be the same width as my stock wide track axles?

3) What all will I need to replace or modify to make this work?  

Thanks in advance for any of your thoughts.

The most glaring issues would be the width and the t-case front output.

Your CJ has an axle width of about 56" and the TJ axle width is 60.5". The TJ has the front differential on the driver's side and the CJ Dana 300 t-case's front output is on the passenger's side. Dana 300 flip kits cost about $500. Or use a different t-case/tranny combo. Not many options for the CJ trannys when it comes to different t-cases.

Also, the Rubicon axles also have flange pinion yokes instead of u-joint yokes, so you'll have to get different yokes or different drive shafts.

The Rubicon lockers also require a low psi air source for operation. I think it's around 5 psi.

Get a Scout 2 Dana 44 Rear end ,about 1/2 wider but Same bolt pattern as CJ.
you will have to weld on new spring pads.
