I have a Moser 12 bolt that was originally under a ls1 car. I've since had the spacer installed to deal with the lt1 brakes. It seems to me though that I am getting axle bearing gease all over the passenger rear wheel? What can be causing this?

more details on the spacer? wheel spacer? what is it exactly?

probably an axle seal

Its a little spacer between the bearing and the hub area to cut down on the brakes rubbing.

Here is a link to directions showing the spacer:

So if it is the axle seal, what could cause that? Bearings have maybe 3k on them, probably less.

defective seal, you may have damaged it when installing the spacer, incorrect seal (i have gotten mis-boxed seals a number of times)

I installed brand new bearings when I put the spacers on, from Moser. Never have been able to remove the bearings without them exploding or having to be cut off. That has been interesting, they really don't want to come off those retention collars.

Any other possibilities? Or its likely I just somehow got a defective seal? That is kind of disappointing when the pair of bearings runs you like $90 shipped or whatever it cost me.

The kick there afterwards is even after springing for new bearings so I could install the spacer, on occassion the driverside still rubs!

Where is the Seal located? From the diagram its in the Axle Tube behind the Bearing?

The seals are on the bearing itself on both sides.

Same Bearings I have on my 9"..is there an inner Axle Seal that goes behind the Bearing in the Tube?

Did not see any seals on either side axle tubes. That is the thing too, its not gear fluid, it is grease, so just kind of wondering if there is anything that can cause bearing seal failure?

X2 on the inner seals on the 9". My bearings are the same style as the ones in the pic the OP has and the plastic seal between the inner and outer races went to hell with about 1000 miles on them, allowing the grease from the bearings to leak out and destroyed the bearings. I picked up a new set at NAPA and had a shop press them on. Havent had any problems with those ones yet but only time will tell.
