I picked up a 1985 Toyota Motorhome up here in BC, Canada that has the bad 5 lug rear axle . It has the 22RE engine with 90,000Km.
Luckily I came just across a 1987 Toyota motorhome 58,000 miles that the owners were going to be a rebuild but they gave up on it. It has the 6 lugs axle (see attached pics). It has a different V6 engine.
My questions are:
1) Would the different engine impact the driveshaft or any other connections for the rear axle swap?
2) What measurements should I take to make sure the new axle fits? Is it just the width between the leaf springs?
3) Should I swap out the front axle as well?
