My view on Green vs Tapered bearings

I will take the tapered bearings any day over the straight roller.

I watched your YouTube video this morning. Well done, my condolences to you and your daughter. Keep your faith and have a full recovery. God's Speed! 65'
My 7 1/4 with ball bearing style rear axle bearings has 315,000 miles on it. Nothing wrong with green bearings.
Tapered bearings offer more surface area and in the 8.75 have been proven for years to be reliable. I like both green and tapered bearings.

FYI
I have run a spool with the tapered bearings just by grabbing a spare spacer, and centering it half-azzed in the center of the spool by "wrapping" it with whatever fits, and won't melt at up to 250*F.
My car spends a good amount of time sliding sideways, so I see the Timkins surviving that better. I see no advantage for Greens in my application, and I don't think that the cost difference is worth consideration.
If I remember rightly; in the 8.25/ circa post 77, the bearings are needle-rollers that ride directly on the axle; now there's a chit design. I replaced a few of those axles with deep grooves worn into them.

I have never like "c clip" axles for several reasons
No side thrust, the whole damn ball 'o wax depends on a couple of weak kneed clips
If the bearing wears/ axle wears, you just ate an axle
HOW ABOUT AN ANNOYING story from the old days
The guy who later was first owner, and sold me my 70 440-6RR, owned a 65 Chevelle when we first met in 68 at Treasure Island Navy ham club. He was an E-5 going to "B school. He had parted out a wrecked 67 Camaro, and swapped in the 350, Muncie, and Ralley wheels It was a hot little number "then" The cam went flat and OF COURSE we put in the 350hp 327 cam "then."
One day we left the island, and he is hammering the thing off the ramp, and "BLAM WHAM KATHUMP BANG" It's BROKE. This is on the bay bridge headed for SF. We coasted into a "turn out" JUST AS THE REAR locked and we skidded the last few feet into the turn-out
So He goes down the bridge to find a call box, and one of the guys and I get it "up." Set one tire on the spare and pull the rear cover. Pulled out some junk to see if it would turn. At least one CLIP FELL OUT. I had no idea--had never seen a "clip" rear axle, and my buddy (from Detroit!!!) said "he couldn't remember"
So the tow truck came --bear in mind this is a busy high speed bridge---and decided to push us to the ramp off the bridge, big rubber front bumper. -----------And off we go, everything is great UNTIL HEADED DOWN THE RAMP We start to hear the RUBBING SOUND, and THERE ARE NO BRAKES!!!! (Single master, 'member??)
BOTH axles had come out and are RUBBING THE FENDERS and the BRAKE DRUMS are clear OFF THE SHOES!!!
But George is a fairly quick guy, and had a Line Lock in the car. He pushed the button, and gave the pedal a couple of quick stabs to build up pressure in the fronts. ----And we rolled down the hill to a stop----
Where the tow truck hooked to the rear, and dragged the thing back to the Island hobby shop to fix..................
SIDE NOTE--------------We exchanged the compete rear for a junkyard one, got 'er all together AND IT WOULD NOT MOVE........the shock of breaking the rear HAD SNAPPED THE INPUT SHAFT in the transmission right off behind the clutch splines!!!!

Actually I'm over 6 ft tall and have a slimmer build... I always laugh at that picture it makes me look short and fat..Man, you're chubbier than I pictured you.
Wait a minute I'm a skinny black guy that delivers chicken...
It may turn into that, but I actually like both styles and have run both without issue. I have zero issue with the factory set up, and zero issue with replacing it all with green bearings if it looks like it ate it's last 2 years at the Crusty Crab LOL

I hate sealed bearings in all automotive wheel bearing applications. Tapered bearings will last the life of the vehicle if serviced regularly.

The factory tapered bearings in my 70 440-6 RR (Dana 60) went something like 90K and I ran the Pea -aye-ess -ess out of that thing
On the other hand, many old ford 1/2T pickups used sealed ball and they lasted long as well. "Up here" in this country, guys used to (over)load the HECK outta them with firewood

I bought my Duster and found the rear brakes were being soaked by diff fluid. Replaced the brakes as well as the inner seals and readjusted the tapered bearings. Soon found the brakes ruined again. Bought new axles and green bearings from Dr. Diff and upgraded to larger rear drum brakes. The green bearings sealed much better and no more soaked brakes. Had a Duster back in the 80's that kept ruining rear brakes and never could find out why. Same issue, but I did not know then what I know now.
Good stuff, it may help somebody solve their issue.

Back then I didn't know about the outer seals behind the retainer plate myself. If you overpack the new bearings with grease, you get to buy new brake shoes.
I Run both kinds , both do as advertised quite well . i like the green better if you change your center section out often because its much cleaner . i have yet to have either fail on me .
