artwigwa Posted August 21, 2018 Share Posted August 21, 2018 (edited) Evening all.. so I'm rebuilding the axel on my 1988 rear drum braked 90 and on fitting the wheel bearing kit there is a oil seal FRC8222 in the box. If correct this outer seal runs on the outer hub seal spacer (pics below if uploaded correct) BUT some fitting guides state the seal is not needed on a 90" I is confused Can anyone confirm if I should or shouldn't this, FR8222. Thanks. Edited August 21, 2018 by artwigwa Added a thanks Quote Link to comment Share on other sites More sharing options...

artwigwa Posted August 30, 2018 Author Share Posted August 30, 2018 Ok. The 90 is not used off road so I'll probably leave out this seal out, any potential probs in leaving the seal out? Thanks Quote Link to comment Share on other sites More sharing options...
miketomcat Posted August 30, 2018 Share Posted August 30, 2018 Leaving the seal out will allow axle oil to lubricate the wheel bearing. The good news is generally the bearings last longer like this. The bad news is like this there is only one seal keeping the oil in the axle so any play will lead to a leak. Either way will work there is nothing wrong with two seals and grease lubrication or one seal and oil lubrication. Mike Quote Link to comment Share on other sites More sharing options...

Mike The seal being asked about here is the outer hub seal, the one just behind the drive flange not the stub axle seal. Which brings me question, what does the lip on the stub axle seal actually press on to form a seal? Is the reinstall order first the outer bearing, then the hub spacer in the 2nd photo, then a nut, then a larger washer locking tab, finished with a 2nd locking nut?
