Front pumpkin leaking grease/oil...

[IH POWER]

Any help on why my front pumpkin is leaking oil/grease? Went out and moved my truck and there was a puddle of sludge under it.

Are you sure it's your pumpkin? Oil leaking from the motor can cover the differential and make it appear that the pumpkin is leaking.

No Im sure. It left a pile of it and its too sludgy to be engine oil. And it stinks like gear oil too

Check your lift pump, and valve covers, thats where I found my oil leaks, and by the time they ran down the hot engine, frame, etc. collecting dust and dirt and grime on the way down, it gave me the same feeling, worth a looking at.

Well, clean off the pumpkin and figure out exactly where it's coming from.

IT's either coming out the pinion seal/axle seals or the diff cover/pumpkin clean it all off really good, then watch for the leak...park over some cardboard and you can see where the drips come from fairly quick...

seems to be leaking out from the left side of it where the left axle slides into the pumpkin. Like in between the spring shackles and the pumpkin.

Sounds to me that the axle seal is gone, means pulling both axles undoing drive shaft and the bolts retaining the pumpkin in place...removing pumpkin, then carrier then seals and replace...IIRC. Good time to drill out a hole on bottom of pumpkin and add a pipe plug for future drain/fill maintenance.

Have fun...it's messy!

and to add to what riot said,,you HAVE to remove the pumpkin,,to get the seals in.. they come in,from the inside!!!! you will need a L O N G pipe,,and a socket,,to hammer the seals in place.. you want them going in STRAIGHT!!!

Two options/opinions....long pipe and socket approach or long redi thread rod and large washers and draw it in if you can that way....both work...both can be a summer time near the lake or ocean..front property too...

Seems like a complicated job. Not too sure on how to take the pumpkin off. Do you mean just take the cover off of it? And why do I have to pull both axles if only the left one is leaking

what is this pumpkin you guys speak of?

Are you sure your breather is not plugged? When they are plugged, they create stress on the seals.

Is it the spindle seal i need to replace or the shaft seal?
