Axle shaft Seals

[money pit]

I bought a 8 3/4 rear end housing and axles. I'm going to replace the bearings with the sealed Green bearings. Since these bearings are sealed, do I still need the outer seal? Or, do I just need the seal that is installed in the housing? Thanks.

Why downgrade what the factory designed ? Tapered bearings are much stronger especially on sideloading( cornering) Green type are ball bearing type.

I agree completely , don't waste $$ downgrading the Cheap green brgs , the tapered roller are a far superior design .

I was looking at the green bearings since some of the rear disc brake kits require the green bearings. Thanks for the info. I was looking on line for the tapered roller bearing. Most places sell the green bearings. Can you recommend a place to buy the tapered bearings?

If nothing else, the linked article below from Doctor Diff makes his case for Green bearings. A different point of view I guess.

Just go to your local NAPA store or any other reputable auto parts store.

Even Dr. Diff sells them... And unless you are going to road race the car you will never need rear disc brakes. The fronts have always done 70 + % of the braking. When I was in the auto repair/tire business for over 30 years I noted that the average customer went through 2-3 sets of front brake pads before requiring rear shoe replacement. When cars are manufactured now a days, it is cheaper and faster to install disc brakes all the way around. Not because the cars Need rear discs. Just the way they do it today. Just use the best quality brake parts that you can find. Brakes/tires are the most critical systems on your car. No matter how much power you have or how fast you go, it all depends on the grip of the tires and the grip, of your brakes. Safety first. Timken bearings are available anywhere in the world.

Thanks, good info on the brakes. I have a Toyota pick up with 265K. I just replaced the rear brakes for the first time.

With the Green bearings, do you need to replace the outer seal? Thanks.

No need for the outer seal at all as the green brgs are sealed both sides

The use of "Green bearing" on the disc conversion is because the adapter blocks access to be able to adjust end play with the tapered bearing. The sealed bearing is a convenience, not an upgrade.
