Re: Changing fluid in Rear Differential
so you have the 14 bolt locking diff . this in the glove box sticker label should indicate G80 this is the dff. code for the locking differential.
on the diff fill area should be a tag which gives you the oil required. should be 75-90 wt synthetic oil.
when replacing this fluid / gear oil remove the rear cover and clean the metal sludge out. also the cover magnet needs to be cleaned . use paint thinner mineral spirits to clean this .
use form a gasket with a thin paper gasket place on cover let dry for 45 min then install. fill to 1/2 inch below the fill hole.
make sure the venting tube to diff is not restricted.
oil should be brown in color if gray its in need of replacing/cleaning out.
