The route the diff oil takes is out of the end of the axle casing past the joke "oil scroll" (of course if you do a lot of reversing, it completely defeats it anyway) and into the hub. Here it gets whirled by centrifugal force (or is it centripetal?) out through the gasket between the flanges of bearing carrier and hub. This is because the flanges are no longer flat and a piece of paper does not seal very well. Years ago the racers started using "instant gasket" and everyone should use it as well. If there is a lot of oil, it will also get through the bearing and a worn-out lip seal operating on a worn-out axle onto the back of the bearing carrier from where it is also whirled onto the brakes. The splines of the half-shaft do not completely fill the splines in the hub, so that is another escape route which leads to oil running down the wheel spokes. Hubs used to have grease nipples, and one theory was that by filling the hub with the right sort of grease, the oil would be kept at bay. Nowadays a lot of people fit shielded bearings (keep grease in and brake dust out) but this does not completely solve the problem. By far the best method is to stop the oil getting out of the axle in the first place using a lip seal. The Ozzies did this by crudely welding a piece of tubing to hold a seal onto the old hub nut, Phil Marino made (makes? - how is Phil these days?) slotted nuts (i.e. the wrong sort) with seals, and here in Olde England I make proper hexagon nuts with lip seals incorporated. One little snag is the half-shaft splines which will not give a very good running surface. Phil solved this by selling everybody his tapered half-shafts, whereas I supply little sleeves which glue over the splines (but you can have tapered, i.e. splineless, shafts if you wish) [quote] Steve Rankin wrote: I have a problem with diff oil getting thru the rear wheel brg to the brake drums on my TC.

Very new, as I have yet to drive one ever! However, that is about to change by this weekend I hope. My pal Rod Ptak, who owns a TC, a couple of L types, a B since new, and is also a recent newbie to this list is attending Silverstone, and I believe will be ferreting out some of you.He would be pleased I'm sure, to bring me back a couple of nuts and sleeves, and probably a couple for himself, and I'm sure could pay you on my behalf. Hope you can undertake this challenge!!
