Oil Leak From Front Diff

[tacker]

Does anyone know where the most common point to check for a front diff that leaks oil only when it is hot.

Not one drop when cold just after the diff heats up then it pours out.

Check the oil level first....might be overfull, although if the breather tube is connected correctly that shouldn't happen. If it is a leak, there are 3 places - front cover, output (drive) shaft seal or input shaft seal. That assumes of course that the housing isn't cracked or somthing unusual like that. Best thing to do is to totally degrease and clean the area, run it for a few k's and then check for the source of the leak.

do you have the breather line that runs right up to underneath the plenum attached?

Have had trouble with both diffs breathing, but never with real leaks
