Voldad Posted July 8, 2020 Share Posted July 8, 2020 I usually deal with Chevys so am not familiar with the ever popular 9” Ford rearend which is similar to my 8” rearend. It looks to me like there is a seal between the available lube in the differential and the axle bearing. Also, since the bearing is pressed onto the axle, I can’t pack it with grease. How do these bearings survive without lubricant? Thanks, Bill Link to comment Share on other sites More sharing options...
Bloo Posted July 8, 2020 Share Posted July 8, 2020 Ford bearings (on the 9 inch anyway, and I think the 8") are sealed and lubed for life. If there is a problem you replace. There usually isn't, but after all these years I would consider replacing them if I had them out. If the seal leaks not only does the bearing get wet, but so do the brakes..... 1 Link to comment Share on other sites More sharing options...
