Leaky rear diff drain plugs?

[bamnq6]

Hello all!

Long time since I've been around these parts but I've got a new query for y'all!

I swapped the fluids in both diffs about a year ago and I've developed a slow weep at BOTH the drain and fill plugs on the rear diff cover. Like 4-5 drips a week (tells ya how often she get's driven). Just last week I changed the oil and figured I'd check how much had leaked... and added about 2 oz of fluid. I'm not overly worried, but I'd rather not stain the driveway with 3/4 of my vehicles...

Both the drain and fill plugs were torqued to spec (20ish ft-lbs?) and still weepy... any advice? I'm sure it's the drain plugs and not axle / driveshaft seals.

Thanks in advance!

I normally put teflon tape around the plugs.

Lincoln I do that as well. OP make sure you have enough in there, my '05 workshop manual calls for an 8oz overfill through the ABS sensor port after filling to bottom of fill plug. YMMV

Yep that.

Thanks for your help all-

I hadn't added the extra 8 oz, but I don't think my Haynes recommended that. I'll ask at the dealership when I pick up new fluid.
