8.25 swap into 86 M body

[white86fifth]

I just bought a chrysler 8.25 rear end from a jeep to swap into my 86 fifth ave and get rid of the 7.25. I’ve pulled the shafts already and everything looked fairly clean inside. I’m going to cut all the mounting stuff off soon. Anyone here done the swap? any suggestions or tips? thanks for your time.

You're going to have to have the perches relocated and maybe even the axle cut down. At that rate you should have started with a Ford 8.8 with disc breaks.

Do you have an axle shop anywhere near you? Easiest is to take both the new and old axles and tell them to match the dimensions and shaft angle.

What do you mean cut down? Like the axle is too wide? I already planned on cutting off all mounts

Cherokee 8.25 is only 1/2 inch wider than the late M/ J body one, according to the the Jeep forums

With both axles there it's worth measuring to be sure.

In total, so 1/4" per side? That really isn't that bad.

I think the peaches are supposed to be at 44 inches, they came with 3.07, 3.55 or 4.10 gears, and 29 spline axels.
