If it is the WJ Dana44A then yes it swaps right over. Not sure about the U joint size between the two though

Ok i found the WJ means newer model 99+ the swap is dana 44 from a 2000 cherokee into a 2002 grand cherokee laredo that has a bent dana 35 in it. Both are 3.73 gear ratio

The A stands for aluminum. The Dana 44A has an aluminum housing. It is NOT a typical Dana 44. And parts are not interchangeable between the Dana 44 and the Dana 44A.
