I've got an 8 3/4 rear and I need to repack the axle bearings. What's the best method to make sure they are greased well?
Plus the FSM DOES instruct you to grease the bearings... so you're wise to do it!I assume you're talking about the factory style tapered bearings and not the "green style" sealed units... I use a "grease needle" on my grease gun and poke it into the end of the cage and pump the cavity full between each roller. Then spin the bearing a couple of times and repeat. After it's in and running, like Locomotion said; they're lubed by the gear oil. I just like to grease them on assembly because my stuff tends to sit around a while before it gets used...
Yes the inner seal should keep the differential gear oil from getting to the bearings, if you have the axles out you can also use the needle to grease the bearingsYes, OEM tapered bearings are what I have. I thought the inner axle seal keeps diff fluid out of the bearing and they are only lubricated by wheel bearing grease?
Yeah, I misspoke in my first post- senior moment having just done a friend's "Brand X" rear... No excuses. Regardless, pack 'em. I like to use the needle if the bearings are already pressed on- the "palmful of grease" is tough to do on a mounted bearing. Or maybe I'm just lame...Bearings are sealed against the diff fluid with an oil seal. Grease with normal packing procedures (grease palm of hand and scrape it in there like your frosting a cake).

Nope! They get greased.You don't pack them. The OEM type axle bearings are oiled from the rear end fluid. Make sure you fill the rear end to the proper level with quality gear oil. Then there are the sealed type bearings that have the lube self contained.
That’s correct. KimYes, OEM tapered bearings are what I have. I thought the inner axle seal keeps diff fluid out of the bearing and they are only lubricated by wheel bearing grease?
If they were dry or new , we just worked/poured a little rear end grease in them ,they are lubed by the diff grease , thats why their are seals outside them ----------That’s correct. Kim
How does the axle lube get past the inner seal?If they were dry or new , we just worked/poured a little rear end grease in them ,they are lubed by the diff grease , thats why their are seals outside them ----------
When it gets worn and develops a leak. Kim

Sorry , but the Hemi I ran for 14 years was .Wrong. They are not lubed by the diff grease.

With stock bearings , Just leave the seals out and see how fast lube will get on ur brake shoes.
9'' ford I had in my vega was the same way-----------Now that's funny. lol
