8 3/4 axle fitting - Im ready for lesson 3 - 06/23/08 10:14 AM

OK, so the factory 8 3/4 had an end play adjuster.

How does the bearing kit offered by Mancini get around not using this?

and is this a worthwhile conversion?

Thanks again

They use a sealed ball bearing assembly that doesn't need a preload/end play adjustment or cleaning and packing with a good wheel bearing grease,
Worth it - IMO - NO. The OEM tapered roller bearing is a superior bearing to the sealed ball bearing. After all servicing the axle bearings isn't something that you do every day. Maybe once in a cars life time. No big deal.

The adjuster is not available new. I have some used ones, however.

BTW as far as I know, I have the best price on Green wheel bearings at $60 pair.

DrDiff - Ill bear that price in mind -

Are the green bearings the OEM tapered roller bearings that Don referred to?

Green bearings are a sealed ball design, similar to what is used in most other non C-clip rearends.

Sorry guys...but my heads hurting!!

If tapered bearings are better - why does every advert for axles I see rave about "green bearings"?

Not sure if this will explain it better but here goes.

All cars came with a tapered bearing for the axles. It is similar to the front wheel bearings. You must adjust the preload on the bearings for them to work correctly.

Green bearings are a ball bearing style. The do not need to be adjusted. They are only 1 piece and do not have a bearing race as like the tapered bearing. They have become popular because many street guys like to swap rear ends in and out depending on highway driving or fun stoplighting.

I agree tapered are a better design, but that said I have greens in my car and so far have not had any trouble. I think both work just fine. Many friends have run greens for years. IF you plan on doing and "drifting" with it, i'd stick with tapered.

I think the Greens are used so much because if you buy a set of axels, they can only put Green bearings on them since the adjusters are unavailable. 7-1/4" axels used bearings similar to the Green bearings.

That more than explains it all - thanks again.
