Front diff is leaking on my truck...damn

[buckshotbarlow]

Ok, 2002 chevy 2500hd w/duramax and the front diff, driver side is leaking...I think the seal is gone...any idea on how much it costs? Gotta get the book out and see what kind of oil it takes so i can top it off...sigh, just got my damn arcadia fixed, and now this...

Takes standard 75w90 for the front.

Mine has been leaking for a few years. I top off the fluid twice a year and call it good. I have been told the "new" seal will leak just as bad and the cost is $600 or so.

Wish I had read that sooner....

I wouldn't recommend letting it get too low, from experience the bearing behind that seal is a bitch to change.

that sucks. Hope you get it taken care of. if it isn't too terrible I would just top it off and check it at each fill up. carry some extra oil in the truck.

The seal is under $50 and takes 15 minutes to change if it's really your diff seal that's leaky. If its a pinion seal it's a little harder to do.

That pinion seal can be fun fun fun.

Watch out for the transfer case on that truck. Apparently there is a flaw at the rear seal of the transfer case where a clip breaks and the shaft wears into the housing. It cost me around $2400 for the parts and labor. It is a fairly common problem on these trucks. They usually go out around 100K-140K miles.

Had the same leak on my 1500. it was like 400 bucks at the dealer. The wacky diff case supposedly needs a special tool. Haynes book said take out the diff and have it serviced by someone with the tool. Look online and see if you want to try it. The seal is almost free, getting in the right spot is expensive.
