I found the instructions here for the fuel filter but haven't found any for the front and rear axles. Does anyone have a link to instructions for this? If not, what is the general procedure?

 

Place drain pan under diff.

Start removing bolts from the bottom up. Only loosen the top bolts a few turns.

Slowly pull on the bottom of the cover to let lube out.

When the majority of the lube is out remove the top bolts and take cover off.

I then clean everything up with brake cleaner and wipe it down.

Let it air out for 5-10 minutes for the brake cleaner to evaporate.

Replace the cover and bolts, no new gasket is needed.

Tighten the bolts in a cross pattern working your way around the cover. Be easy, they will break if you tighten them to the recommend torque in the FSM.

Fill with fluid.

 

First step I would have is to clean off the exterior of the diffs before doing anything. Great story on here is a guy that didn't do that, and of course, got sand in his diffs. Spent hours cleaning it out...
