2003 DII, 112k, also have 3 amigos on + brake light on the dash.

What initially looked like excessive break dust buildup on my right rear wheel, appears to be gear oil?? from the rear differential? (there is no brake fluid leaking)

So, since I couldn't find anyone with the same problem in previous postings, I thought id ask, is my guess right and what needs to be done to repair it? Whole new hub? bearings? seal?

I am driving about 250 miles back to school tonight so I'm planning on topping it off with some gear oil from advance if I don't hear otherwise. Thanks for taking a second to check this out!

The actual problem is the drive shaft oil seal / "O" ring has gone.

Does not need anything except a new seal fitting, how ever, if the brake pads are heavily contaminated with oil I would personally replace them to while its all off.

Obviously the hub and drive shaft need to come off / out to do it, but its not a really big job. "If" there is any movement / wear in the bearing / hub assy, then a good time to replace that as well, but they are costly !! so if there is no wear then no need to bother

This will give you an insite to the hub removal, its for the front, but more or less the same for the rear

I had the same problem a few months ago, I think I had water in my diff. I replaced the hub O-rings, drained and refilled diff with heavier gear oil and put in some lucas hub oil.

 

Check your axle breather tube to see if it is clogged.
If it is the pressure that builds up inside the diff will blow out the weakest link, a weak seal for example.
It might not leak if there were no pressure, but because there is it will leak.
So check that, it is easy to do, just remove it from the axle and put it to your lips and blow through it, if you cant then it is clogged and needs to be replaced.
If it is the seal then club it.

 

ok i'm going out to look for the breather tube now, but I was unable to find the mentioned hub seals online. Any idea where to grab one of those?

thanks so much for all the help guys..

Air is flowin, so that's not the problem unfortunately.. I'm going to order this o-ring for a buck, I think its what I need. No play in hub whatsoever, and I'm just gonna blast the brakes with cleaner.

Order 2, if you do need to replace the hub then you will already have the gasket.

 

Ordered 2 o-rings today.

So, to install the one in question, I pull the wheel, pull the hub with the 4 bolts holding it on, then do I pull the driveshaft? or can I pull the old ring and press the new immediately after removing the hub

thanks again guys!

 

I do not know.
