new 5.13 leaking diff fluid
 

wondering if anyone has any ideas
we installed 5.13 a few weeks ago, install went smoothly
got g2 aluminum diff covers too
got home after first night little oil spots under the diffs
started noticing this more often
also noticed the driver wheel well is covered with diff oil

well we did the break in didnt change the diffs but changed the fluid
800 miles later pulled the diffs re rtv'ed them with high temp rtv(red stuff) added som diff oil to the front it was low
the rear is no longer leaking but the front it from the breather tube, like wheel well is covered, front driver lower control arm...
any ideas?

most likely.....front is overfull. i doesn't take much to make it puke out the breather.

pull the fill plug and let the excess oil drain out.

+1 I did the same thing, overfilled the front diff:naw:

i dont think its overful
we out 1 and half bottles in with what didnt make it from the bottle makes about 1.4 which is what it says to put in

:dontknow2::dontknow2::dontknow2:

Same here ....my G2 gears did the same. After changing fluid no more leaks. I think it was over filled. By the way I love my 4.88s! No noise or problems after 1500 miles.

x3.. i overfilled my front with my arb's, and it was spewing for a week and i let some out. ran right down driver side like u said, onto fender liner, frame, control arm, and the lovely cat which made for a geat smell while driving. my breather goes up to the top of the cowel on driver side where the hood seals in the corner. i would say keep letting a lil out till it doesnt come out anymore.
