So I just replaced my balljoints in both sides a couple of weeks ago and replaced o-rings and wheel seals at the same time. Came out after work today and there's diff fluid leaking out the en of the axle housing on the drivers side. Any suggestions on fixing this?

 

unfortunatly when you slid the axle out and then back in, you may have damaged the inner seal.... which sucks
you will need to take it all back apart including the front cover, remove the diff and replace the seals.
and you might as well replace both while you have it opened up

OR
it just could be seeping out and not a big deal..but not likely

i usually grease the end of the axle where the seal rides and the splines, helps it slide over the lip of the seal without damage.

let us know how it turns out

 

So there's a seal internal to the diff? If so, can the seals be replaced without taking the gears out of the diff?

 

Does anyone have part numbers for these seals and possibly a diagram of location and placement.

 

There was a thread on this yesterday ,let me see if I can find it
