So I go to the stealership today to get my oil changed and they tell me that my front diff is leaking. They said I don't need to replace it immediately but they recommend that I do. My question to everyone is does anybody know about an aftermarket front diff that is better and/or cheaper than the stock front diff.

No aftermarket front diff available. 2004-2005 had a weaker case and half shafts that tended to pull out resulting in leak around seals at flanges where CVs bolt to front diff. The front diff was improved 2006+. Sometimes they also develop pinion seal leak, which can be fixed fairly easily. Where is it leaking?

It looks like the leak is coming from wear the CV bolts to the differential. Any idea if its just a seal I need replaced or if the whole diff needs to be replaced. The dealership told me the whole diff needs to be replaced but I don't know if I believe them.

It typically leaks around the CV flange because the half shaft pulls out. The half shaft is held in place only by a clip that rides in a groove on the inner end of the half shaft inside the diff. When the shaft pulls out, it can sometimes be pushed back into place, but sometimes it damages the seal and/or the splines on the inner end of the shaft. They redesigned the diff for 2006+ to make it more difficult for the half shaft to pull out.

That's probably what's wrong with it. The leak looks like it's coming from right around where the CV goes into the differential. Is there anyway to get that problem fixed without replacing the whole differential?

Toward the end of that thread, there is a post by a mechanic about rebuilding the old diff using the upgraded parts. That requires a skilled mechanic, a substantial amount of work, and still leaves you with the older weaker case.

Looks like I'll just have to cough up the money to get a new one when this one eventually goes out.
