Thanks | | | | | Joined: Feb 2016 Posts: 1,841 'Bolter | | 'Bolter Joined: Feb 2016 Posts: 1,841 | I think you are talking about the gasket between the hub and axle shaft, if the metal is in good shape I would clean all mating surfaces with brake cleaner and use some non-hardening gasket sealer with the original gaskets. Mine were not metal, I made new ones with a medium weight gasket material.

I have the gasket material to make them, however was curious if new were available. | | | | | Joined: Feb 2004 Posts: 28,674 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 28,674 | The best axle "gaskets" are soft metal, either copper or aluminum, and need to be coated with a non-hardening gasket sealer. If there is any movement at all between the axle and the hub, even a few thousandths, a paper gasket will be damaged and start leaking. Bigger full-floater rear hubs have tapered metal cones that grip the bolts tightly and fit into corresponding tapered holes in the axle flange to prevent any movement. 3/4 and 1 ton rear axles usually don't have them, but the OEM bolts have an unthreaded shank under the head that's a very close fit to the holes in the flange.

If assembled with a non-hardening cement, they seal pretty well. I have sources for the military style axle gasket. Do you have measurements from your gasket...maybe they are the same? | | |
