Does anyone know off the top of their heads if a 87 rear axle will fit on a 89 4x4 both with 22r(e) engines? I was going to do an entire swap but the guy told me it was a 89 and when I got there, I found out it was a 87. I read around and could not find a definite answer.

 

Yep. Both IFS axles out of a 4cyl. As long as they're both 22re and not 3vze or 22ret, you'll be just fine. Or if it was elocked you'd have to do some modding.

 

As long as they are the same gearing it won't matter. 4cyl and 6 cyl all use the same axle housing (except pre-IFS, but 3rd is still the same). The only difference is 2 pinion vs. 4 pinion. I have a welded 4 cyl for a trail spare, and it fits fine in my 4Runner with the 3slow.

 

Will it be easier to swap the 3rd's or the whole axle? I am going to pick it up in a minute. Anyone know how long it will take to do either job? I would rather keep the axle on my truck to keep my brakes, bearings, etc. I would also like to know the difficulty of each job. Thanks for the help...
