I did remove the ABS sensors, but not the pin. I'll try again this weekend. At least I have the re-useable gasket now.

Axles, bearings and Motorcraft axle seals were new about 10k miles ago. I Auto-Cross my Marauder, so that gear lube is getting thrown side to side. Should I apply a little RTV on the outside of the bearing to seal it against the axle housing?
