....but if you really did find that type of bearing in your 8 3/4 , somebody swapped that ***** out because they never came with green bearings.
There, I fixed it for you.

Well, then for some reason somebody put green bearings in an almost-new '70 Road Runner 8.75". The car didn't have 30K on it when I got it. My assumption was it was built that way.I have never seen Green Bearings in any 8 3/4, ever, unless someone replaced them. All the way thru 74 when they stopped making 8 3/4 rears.
O.K. maybe I am wrong about what they came with. But the greens were in my '70 RR with under 30K on it. Not sure why or how they were in there, but I distinctly recall my friend's Dad telling us that when were ready to adjust the bearings to come and get him and he'd show us how. Well, he was surprised when there was no adjuster!I had a '70 Road Runner 8.75" that had the green bearings OEM. I know this because I was the 1st person who ever had the rear end apart to replace the 3.23 peg-leg with a 3.91 Sure-grip. Is this "proof"? Besides, GM and Ford used the green-style bearing almost forever. But full-fledged race cars do not count... anything serious has full-floating axles, and when those AARs or TAs were converted to race cars the green bearings were obviously removed. But that isn't how Ma Mopar delivered them from the factory.
With regard to the TA/AAR cars, nothing was really stock on the ones they raced.

The supposedly “best” rear end, Ferd 9 inch uses a green style bearing and it’s used from daily driving to pro-touring to auto cross. So why is it when the same style of bearing is used in a Mopar, they can’t take the side loading?
The green style bearings have balls in them, The Ford 9 inch uses straight rollers in their bearings, at least from what I remember. I used 3 sets of Green bearings and I don't believe I got close to 10,000 miles out of any of them. I will never use another set of the Greens! Does anyone use BALL bearings on their front brake hubs? I don't think so! That went out in the 50's.
Sorry, I haven't worked on a Ford in a long time. I didn't know they used tapered bearings.
Agreed. And also the calipers and rotors become your safety cushion for side load and failure. I believe straight cut bearings should be used with disc. I never had rear disc on a pre 72 car?One of the disadvantages to the tapered bears is that you will have trouble running disc brakes on the rear axle. The preload on the tapered bearings allow the axles to move slightly. I had trouble with this years ago. If the brake calipers stick sliding for any reason then it will grind one side down fast and drag.
