4EAT Front diff installation

Post by Lorilover »

Overhauled my 4EAT front diff and now I have groan while driving. Sounds like the crown gear and the pinion is not meshing properly.

I was hoping to find some advice/tips on how to properly set the gears up when installing the diff assembly.

BTW- I've done extensive searching on this specific topic but no clear details on gear setup found.

vehicle is a '94 Legacy SS.

Did you set the backlash properly when reinstalling the diff?

I tried setting the backlash with the diff on the car after the fact. I did not realise the backlash was that important.

The service manual outlines that backlash is set by rotating the retainers by the CV shaft splines.

I was hoping to get away with doing it on the car instead of removing trans again. Anyone tried this with the trans in the car. :roll:
