Dana 60 Outer Bearing Races "Cracked"

[RJRENTON]

Outer axle bearings and no I don’t know the part #s as I didn’t look them up. They may have not been the Green type roller bearings but they were still a ball bearing on the Fords. I never mentioned carrier support or pinion support cause that’s not what this thread is about.

Roller bearings are not ball bearings....there is a distinct difference between the two types no matter who manufacturered the bearing. I refer you to NTN AMETICAS.COM/PRODUCTS for a reference to besrings....interesting readings for reference......

We get it Bob, you don't like green bearings.

The only "horse" being beat upon are the people that don't know or understand the differrnce in the design capabilities and YES i don't like green besrings......

Lots of modern vehicles use roller wheel bearings with a “sealed hub” design. But you may notice that they are about twice the size of these green bearings, and thus have way more side thrust capacity. Why do you think that the entire auto industry used tapered wheel bearings on the front of virtually every every vehicle produced in 60’s and 70’s?

Lots of modern vehicles use roller wheel bearings with a “sealed hub” design. But you may notice that they are about 4x the size of these green bearings, and thus have way more side thrust capacity. Why do you think that the entire auto industry used tapered wheel bearings on the front of virtually every every vehicle produced in 60’s and 70’s?

I'm aware of the differrnces.....in fact, my Cadillac Escalade/GMC YUKON DENALI with ALL WHEEL DRIVE uses the bearing hub/rotor assembly and i just paid $2400 (parts snd labor) to replace the assembly because the bearing's failed (non greasable, non serviceable). The reason for the overall change is the switch to front drive that is required to handle axial plus radial loads plus steering movement All these factors are taken into account in the selection of the bearings used.....sperical ball and duplex angular contact type combined.....especially with today's suspension geometry designs.....yesterday's design's using rigid axle assemblies and fixed front spindles.....just my opinion of course.....

I remember when I worked at a Dodge dealership in say about '71. We had a meeting with a Chrysler field representative. He told us about design engineering, and design for failure. Nothing lasts for ever Bob, if it doesn't fall apart at the finish line, it's over designed. Get over it, tell us how you really feel.
Just my opinion of course.

well i was told when using green sealed bearings you must remove the inner axle seals , so gear lube can get to those type bearings to cool them off . and yes standard tapper bearings are heavily greased and re-greased over time for their cooling .

Factory bearings should be regreased at least every 50k, 30k even better. They die a horrible death at about 70k with no maintenance. I Watched my dad learn this the hard way more than once as a kid.

General Motors used the green roller type bearings till 1964. Ford continued on till the early 80s. They used the diff pin for the axles to but up against with about .010 play. They made millions upon millions of miles with them. Kim

Oh yeah, the same guys that used millions of c-clip axles that are banned in drag racing for anyone making more power than a 283??

I've used both factory and the "green" style. The only one of mine, or any I've worked on over the last 30 years that's failed was a factory style. And only ever 1 failure. As mentioned before the pissing contest got started. Are the axles bottomed against the thrust pin in the carrier? Or being a racecar is it running a spool?

Highly unlikely the factory bearings failed because of design.

I agree. Just stating the only failure I've ever seen was a factory bearing. I have worked on a bunch of Hot Rod stuff for years. Axle bearing failure is rare in my experience.
