that makes sense...the extended lip runs on the back of the stub axle...haynes says."make sure the sealing lip is facing inwards"..very confusing,,,,,maybe thats not the sealing lip haynes is refering to....or does he mean inwards towrds the center of the vehicle..thx for the tip anyway gruntus..as for running the bearings in the axle oil.although the lube would be probably be good enough, how can you be sure that the bearings are running in sufficient oil?...also, because the brakes are so close to that seal they becaome more vulnerable than when using the grease and the stub axle seal.....nick
