It's hard to say if your ARB would fit into his rear axle Lorie since the two of you could/probably have different rear axle types. What is your rear axle type (Dana 35 or Dana 44) and what is his axle type (Dana 35 or Chrysler 8.25"). A Dana 35 differential cover is perfectly oval & an 8.25 is a little flatter on the top & bottom. They'd have to be the same for your ARB to fit his rear axle.

ARB is case specific.. so if he has the same axle then it should fit. however most 99 cherokees I have come across have the 8.25 axle. Which is a decent axle.. 29 splines upgrade to alloy for about 200 bucks and run 35's locked on it. (have one in my cherokee)
