Suggest to remove cover and replace gasket with Permatex Gasket Maker Silicone. Fully clean and dry apply a 1/4 bead on cover and bolt down to 20 ft lbs. go around several times to compress silicone. Let silicone cure 30 minutes then refill.
Well, at this point, you're probably overdue for a fluid change anyway. Drain the rear differential, take the cover off, clean the surfaces, make a new gasket out of red RTV silicon (Here's how: run a bead all the way around the inner surface. Put on the differential cover, all the bolts, and then pull the cover back about a quarter of an inch. Let it dry. It is now a self-made gasket that will actually crush and hold tighter than if it is simply squashed in while wet.), refill the differential, and you should be good to go. A little oversimplified, but still, main steps!
The cover gasket is silicone and is not designed to be serviced without removing the differential assembly.You will need to remove axles , driveshaft , and maybe the spare tire to get differential out.
put flat pan under the housing remove the bolts holding the cover usually 10 or 12 (1/2 or #12 metric) bolts? allow the rear end grease to drain... then scape off the old gasket clean with brake cleaner spray install either new gasket or form one with oil resistant silicone put the cover back on , dont refill the fliud for at least 12 hours if using silicone. Also check the front driveshaft rear end yoke seal....they sometimes leak making the illusion of a rear end pan cover leak...if that is leaking you remove the shaft carefully...remove the large yoke retaining nut, replace the press in seal...be sure retaining yoke nut is properly torqued when reinstalling .
The axle needs to be removed to replace the seal behind the flange.this is not expensive but requires opening the rearend cover.So you will also need a gasket for the differential and some new gearlube.
