I have a chance of getting a TJ D44 with 4.56 gears and an ARB fitted. XJ D44s are not available in the UK, the only 44 equipped Jeeps sold were the TJ, WJ and a few FSJs. I have to consider doing something soon as the D35 rear end in my '92 4.0L now needs rebuilding and I need to regear anyway as it's on 3.07 gears which makes it hard work on the highway with the 31" tires. I was going to swap in a non C-clip 35 with 4.11s from an '87 2.5L XJ and throw in an Aussie locker or similar. If the TJ D44 isn't too narrow andt there aren't too many other potential problems I reckon it could be a good deal. I am anticipating having to cut off the coil spring and track bar mounts, weld on perches for the leaf springs and shorten the driveshaft to fit it to the XJ but was wondering if any of you guys had tried it before.
