How to fix slack in differential?
 

I have a lot of slack in my rear diff. Does anyone here know if it can be tightened?

Speak to David at API, not sure if the slack can be removed though.

Yeah the backlash can be adjusted but I don't know if it's recommended to adjust it yourself unless you know what you're doing. I fixed my lsd (new discs) but didn't touch the backlash preload (which was ok in tolerance anyway).

The repair manual describes how to do it though.

Does anyone have a link for that manual?
