Up

So, I thought my Old Car's differential was making lots of noise and needed to be rebuilt. So, I tackled this project. The ring & pinion is from Weir Performance, as they are the only place I found a 4.30 set. The rest of the parts were from Toyota. This is not a project for the feint of heart. It took many iterations of measuring, taking it apart, adjusting shims, putting it back together, measuring, etc. A press is required. These photos are a summary, and don't show how many times I took it apart and put it back together. I would guess I did that more than 20 times.
First step: remove the diff from the car Remove the back cover After removing the c..press out the pinion Dirty parts
