Reading Ma.
I know there are the two types of green bearings for my 8 3/4. Are the snap ring style supposed to be safer or is it just a preference thing?
TIA
 
Front wheels have 2 sets of tapered roller bearings. Rear wheels (factor original) are also tapered rollers, but just one set?

Ball bearings don't have the load carrying capability of roller bearings. But you don't need to set the preload for ball bearings so they are easier to install, is that why they are available? Why not use non-tapered roller bearings?
 
Some people don't trust them. I've had no issues with them other than they don't last as long IMO. Today's vehicles use them (sealed bearings) mind you I'm no expert.
 
I always laugh when people question green bearings. It's not like they've not been used for close to 100 years. Ford used them a ton in a LOT of Ford 9" applications, just like most of the other big three. Chrysler used them in tons of 7.25 rear axles. There's nothing wrong with green bearings.
 
When we talk about "green" bearings, are we talking about any bearing made by a company known as "Green", or are we talking about ball bearings (likely or only made by the Green bearing company) used as replacements in 8.75 (and I guess 7.25) rear axles?

Are we sure that Ford used / is using Green ball-bearings or tapered roller bearings?

I read references to a green STYLE bearing, which could be or is made by Timken (and others). So now I'm confused as to what exactly is meant by "green" here.

Edit: A google AI summary says that there is (or was?) a Green bearing company, and that a green style bearing always refers to a sealed, non-adjustable ball bearing.

Confusingly, another google AI summary says "Yes, Ford does use green bearings, specifically the green bearing brand Green Bearing Company. Green bearings are a type of tapered roller bearing used in various applications, including wheel hubs, and Ford may use them in certain models, such as the Ford Super Duty, as highlighted by The Timken Company. Green bearings are known for their reliability and long life, making them a popular choice for wheel hub applications."

So I'm seeing results here that claim green bearings are ball bearing AND tapered rollers. What is the actual truth here?

The caged roller bearings. Not the tapered bearings. Green company made or makes them. We call them Green like we call tissues Kleenex
 
The Ford "green" bearings made by timken are hub assemblies and likely have 2 bearings in them.

I thought I had seen someone take apart a worn green bearing from a mopar rear axle - and it had ball bearings?

in the mopar world common parlance for sealed ball bearings is "green bearings"

there's basically two types for the 8.75, the factory tapered rollers that are "two piece" and (obviously) not sealed and the sealed ball bearing. you'll hear them refered to as "tapered" and "green"
 
So is it 100% true that a "green" bearing is always going to be a ball bearing?

Is it also 100% true that the factory bearings in these mopar rear axles were always tapered rollers?

8 1/4 uses caged straight roller bearings:

Ford 9" came with caged rollers like the 8 1/4 I believe. @RustyRatRod knows for sure.

7 1/4 uses tapered rollers like the 8 3/4 as far as I know. (and I will correct this post if I am wrong)
No Mopars came with caged ball bearings like the Green bearings are. Ford 9" came with caged rollers like the 8 1/4 I believe. @RustyRatRod knows for sure.

Lots of Ford 9" came with green bearings later. I don't know when the changeover was, but there was one. Also, the 7.25 Chrysler rear used the green bearings for a long time. That's what Vixen has. I know, because I've replaced them. This is the Precision number from O'Reilly.

Axle Bearings
 
Good topic, O.P.
When I visited Kass at Dr.Diff a few years back, he said that there were no issues using the new ''green'' bearings that he sells.
I bought some for my 8 3/4'' rear end under his recommendation.
I still haven't used them yet, and I am still reluctant to use them.
I have heard bad stories in the past about them failing unless they're used in a dedicated 1/4 mile race car only.
Or is that just the old style ones?
The tapered roller bearings that the factory used has to be better, if not, then why were they used O.E.M.?
Were they overkill, or really used because they were much better than the roller ''green'' bearings?
I'm still on the fence with this.
Maybe Kass will log on and straighten things out.

I've used them on both my Darts. I don't beat on them like I use to and they have held up fine. I agree Tapered is better. Green bearings you can bolt on and go (no adjusting preload) with the snap ring style as posted in Post 2.
 
I think you are ok as long as you don't do road rally's. If you think about their design, you can see why they may not like much side load.
 
How long have FWD and AWD vehicles used the green style bearings? Our 04 Escape 4WD has almost 200K on it and still has the original bearings. But they don't hold up? You think we drive in a straight line everywhere? Yall are crazy as heck. Go drive down the road. Nothin but green bearings all around you.

I think they call them "Green" bearings, as most guys don't like Green... :poke: :lol:
