Changing Gear Ratio Rockwell Diffs - DIY Job?

Lining what up? They come out one way they go in one way! I’ve used everything from a forklift to an engine puller. Just a lot of dang work without proper equipment! But it can be done and has by many unshaded no tree in Texas wanna be mechanics!

 

The only trouble I see is the fact that they are so heavy and odd shaped.

What about the yokes? The nuts are very tight.

 

My remand came with yokes!

 

Back yoke on Thur shaft I use one inch air gun!

 

Labor is cheap compared to the cost of the reman diffs. Pay a shop that knows what they are doing to stuff them. Screw it up and have to do it again and you will wish you had.

 

Your so very right, and warranty against oil leaks and everything else! But he said he was looking to do it so just trying to help!

 

One time only, changed a front diff on dump truck side of the road. Used the bed to lift it.

I can rebuild diffs. Why dont I? Because the time it takes to order and assemble new parts. Get remans from a reputable shop. Swapping them can be done in a parking lot by a monkey. Why pay for someone else to do that? Biggest thing is cleaning the housing to perfection and might as well do wheel seals even of they ain't leaking. Heck a every day engine crane makes it simple.
