Do I understand correctly that these are not tapered bearings? Who is the source?? I tried to google and could only find info on Oilite Are GBs more or less expensive than stock bearings? Using local sources, I can put new tapered bearings in, for about $85 + sales tax, including removing old and pressing on new. Do Greens have to be pressed on like stock tapers?

they are ball bearings, not tapered bearings

a few diff sources

priced about the same

nowhere as good as tapered bearings

they are pressed on...

Agreed. For drag racing they are OK, for street driving no, and an autocrosser would destroy them in no time. They don't hold up well to side loading (cornering).

A tapered Timken bearing is a beautiful engineering masterpiece.

An adjustable, Set 7 bearing is a needlessly complicated design that weakens the differential, limits side gear spline engagement, and is prone to leakage and dirt/water contamination in many applications. In addition, axle flange stand-out is not held constant unless you blueprint the axle lengths.

Although most people won't have problems with the snap-ring style Green bearing (not the crimped on flange, RP-400 design still sold by Mopar Performance), the non-adjustable, 3.15" bore Timken set 20 tapered bearing is the strongest, commonly available wheel bearing. Unfortunatley, special housing ends are required to run this bearing on a Mopar application.

A statement like that begs a lengthy detailed explanation.


I'm supposed to respect my elders, but its getting harder and harder for me to find one now.

I offered a detailed explanation several times in the past.

In fact, I just spent 45 minutes typing another detailed reply. When I hit the submit button, the computer locked up and I lost everything I typed.

I'm not in the mood to type it again.

Thanks Doc and to all. I guess I really just needed the tapered vs ball question answered.
BTW Doc, I know just how ya feel on the puter problems and I work in comp tech support

I love responses like this. I have been using greens for almost a 100K, and I'm not a drag racer...Changed the first set @ 50K.

.....I've used the "green" bearings since they've come out.......I haven't had to change out a set Yet!.....in decades!.....and I punish my cars, when I drive them on the street, or track(straight or twisty).......can't tell you how may tapered Timkens I destroyed over the years!

I have been told you can't run them on the street for years and that is total crap Has anyone ever tore apart a 7 1/4 rear end and looked at the bearings,they are small green type bearings with millions of rears on the road in a,b and e body cars that have that rearend in six cylinder cars.I have run them for years in my cars and had zero problems,besides the bearing for a 8 3/4 is much bigger than the 7 1/4.No doubt the tappered bearing is stronger but the green bearings are stronger than most people think

Hmmmmmm This brings me back to my other question. I've done some pricing and I can get stock Fedral Moguls(?) pressed on for $85 plus tax and seals. Can I do Greens that cheap?

I sell green bearings for $60 pair. Price includes gaskets and bearing retainers.

OEM bearings require inner beaded steel gaskets, outer foam gaskets, inner seals and outer seals. Are your bearing retainers in good shape? If the adjuster is bent, you can't turn the threads. New ones are not available.

If you have your own tools and a shop press, you buy the bearings at wholesale price and do the press work yourself. Thats how I handle it normally. I have had a few experiences with machine shop press work that resulted in my needing to replace parts after they just threw it on a 60 ton press without any of the normal support for the item being pressed and wound up with distorted or cracked parts.

Plus, I seem to have a phobia about working on my own cars.

My concern is that the only reason these need replacing after over 100,000 miles is because they got rusty. I really am not 100% sure its even the bearings making the noise I hear but I figure its the best place to start. It just SOUNDS like bearings The car sat in a flood after a hurricane and then sat for ten years. They had a crusty residue that pretty much washed off with solvent but I didn't go to the trouble of doing a thorough job as I figured I would replace them anyway. I just packed as much grease in as I could with them still on the axle and put them back in. I believe if the car hadn't got a soaking, I wouldn't have this issue

You know the old saying,"if it ain't broke we'll fix it anyway"! As far as I'm concerned,green bearings are something else we didn't need.Other's opinions may vary.

Good luck.

Get the greens from DoctorDiff and be done with it. If you have a failure let us know.


Just enjoying the drive...... Back to basics with a little boost thrown in.

If the bearings cleaned up and aren't pitted they will be fine. You never remove the bearings from the axle to clean and pack only remove to replace as there is normally no salvage once removed. Clean and inspect and pack with a needle on a grease gun to make sure to get grease packed in between all the rollers and smear a liberal coat on the bearing face when installing. Remember they get no other lubrication and are not lubricated from the rear end lubricant. The inner seal should keep all rear end lubricant out of the bearing area. In your case it doe sound like they should be replaced.

OK, I'll make it easier, you said:

An adjustable, Set 7 bearing is a needlessly complicated design that weakens the differential,


"Needlessly" is a relative judgement but how does it weaken the differential compared to the Green?


limits side gear spline engagement,


In a stock differential?


and is prone to leakage and dirt/water contamination in many applications.

Only if submerged in water or improperly installed. The seals on the Green have limits too.


In addition, axle flange stand-out is not held constant unless you blueprint the axle lengths.

That's the one I don't get. Please explain.
