1993 Isuzu Trooper rear axle

Ok first off you will need to pull off the rear cover and see what kind of rear end you have. You either have a C-Clip rear axle or you have a rear axle with a bearing pressed onto the axle. The first is easy to replace. You jack up the rig and put it on tack stands. Remove the tire from the axle to be replaced. You then remove the rear cover and then you will see a center pin and on one side of that center pin is a lock pin bolt that you need to remove and then remove the center pin. Now you remove the brake caliper and rear rotor. Now push the axle in and remove the C-Clip on the inside on the end of the axle and pull the axle out.
Now if you have the other type of rear end then you need to jack up the side you need to replace and then remove the tire and the caliper and rotor. Then you will see 4 bolt or nuts remove them and pull the axle out then you will need to have a bearing pressed onto the new axle and replace it.
