Leaking Rear Differential

[JDeere7296]

Hey Guys,

Is it normal to have some oil seeping out around the seal on the pumpkin of the differential. Its not enough oil to drip, but is stays wet around there. Do I need to replace the seal and if so what causes this to happen, I only have 32,000 miles on the truck? The diff. is the G80 with 3.73 gears on a 2500 LD 4x4.

Thanks for your help.

Personally, I would not worry about it. You could check all of the bolts too and make sure they are still snug.

Yeah, I did tighten the bolts about 2 weeks ago and they were not snug all the way. I cleaned all the oil off of the diff. but I checked today and new oil has shown up, so I do not know. Maybe seal was bad to begin with. If it does not get anyworse maybe I will leave it alone.

Thanks for the help Snoman.

I would check your level just to be safe. It should be fine though. By not having the bolts tight it may have caused the seal to snafu a bit. Hence why it's still seeping out. Do you by chance jack it up by the pumpkin?

[JDeere7296]

No, I don't think I have ever placed a jack there, I usually put it closer to the wheel on the axle. Maybe you right, the seal maybe warped just enough to continue leaking. I will check level this weekend. Thanks for the help.

I use the pumpkin to lift the truck all of the time and have never had a problem. I would replace the gasket and change the oil though. It can never hurt, however, it always helps to do PM.
