Yep, what he said. 84-86 Trooper, 87s *MIGHT* have the right parts but some of them also had axles more like an 88 trooper which will not fit in the LUV housings. (Technically, the front of an 88 should fit the back of a LUV, but forget I said that just for simplicity sake.

) The front is fairly involved to remove with all the IFS stuff, but the back just pull the four bolts to the bearing holders and then the axles slide right out. The 3rd member unbolts and comes out all together. Alternatively, you can probably take the whole rear axle, leafsprings brakes and all.
