What`s the issue with green bearings - are these ball bearings as opposed to conical roller bearings?

Are roller anxle bearings no longer available? Seems to me that appropriate conical rollers would still be available from bearing supply places.

The original set 7 rear wheel bearings are alive and well. Use them whenever possible. Mopar provided us with the beast bearing as original equipment.

Folks think the green bearings are better because hey need no adjusting when intstalling axle shafts. As in no thinking required. It does make the math on narrowing a rear end easier.

Let the begin

i think if you are spinning your tires or cornering fast you will never see the benefit of tapered bearings---you cant get enough traction----if it did make a difference there would be ford and chevy axles litering the streets---now if you dropped your car off a cliff that bearing would get its full use but everything else will be bent-----and why did chrysler ditch them?

Eliminated because they are Expensive and take more time on the assembly line. Just like factories going to 4 lug wheels, you doing that also?

If you keep the tapered rear bearings cleaned and packed, have you ever had one fail?

It is not absolutely necessary, but if you want a cheap junk bearing, buy a 60's GM car with the axle as the bearing race.

I used the green bearings when I built the Dana 60 for the '64 Polara, but I won't use them again if I have a choice.

The Ramcharger has a Dana 60 that I built with large Ford ends and the large Ford sealed bearings. I don't have to play with axle bearing pre-load adjustment or worry that I have not packed enough grease in the wheel bearings. That is old school.

Green bearing are for lazy mechanics. Now if you want US made tapered roller bearing you have to go to a industrial supply house.

Never had a Green Bearing failure or issue in 3 decades of use in Dana 60's or 8 3/4 rears on the street or track/road course, I have had several failures of factory tapered bearings in the last 40 years however...go "green" IMHO

On the other hand GM's half- a-- penny piching design has resulted in a money making opportunity for the axle Mfr's

My experiences are quite the opposite in that I have seen several green bearing failures anywhere from 10K- 50K miles but know of several factory cars that have exceeded 250K with no rear end service of any kind. I would question how many of the "green bearing" conversion vehicles have seen that kind of service.

Been using Green bearings for many years without a single issue....same goes for factory tapered bearings. What's bad for axle bearings are rear wheels with excessive offset. Seen quite a few with so much offset they were literally riding on the inside half of the tire.

I have green bearings installed on my dana 60. I have to admit, they made me nervous when I saw that there really isn't much keeping them in place, specifically on fast hard turns. But I've never heard of them failing or sliding out of place so if they work/last just as good as properly set tapered bearings I see no reason not to use them

It depends on what green bearings you buy. I replaced an old set in my Dana where the plate was made on the bearing and were bent. I replaced them with a bearing with a separate plate that Dr. Diff recommends and sells what a difference in quality and strength. Trust Cass you get what you pay for.

in my opinion the only way to properly clean and pack the tapered bearings is to cut them off and put on new ones----yeah i know there are guys that say they can pack them by sqeasing grease in around the corner and turning them----but you sure dont do your front hubs that way do you?-----maybe there is a way to put a grease zerk on the hub and do them like a trailer axle--then you would be in danger of taking out the seal with too much grease------not much in favor with the make do idea.....

I the first set of "green" bearings I bought from Summers Bros. back in the mid 1970s failed and allowed the axle to slide out of the rear end housing on street car due to the inner retainer sliding out of place The customer was on his way to northern CA from So Ca and had to have it fixed on the road, NOT GOOD Same thing on a drag car at the races, retainer didn't hold the bearing in place and the axle slid out making the tires rub on the rear 1/4 panels
Maybe Murphy loved messing with me back then,
No other failures since then
The tapered Timken Roller bearings are a lot sronger for road use as well as being a lot more money when replacing them
I use to work in service stations as a kid and I have replaced a lot more ball bearings and races on the front hubs of the older GM cars than on either Ford or Mopars with tapered ball bearings back then
The ball bearings will not take any side preload at all, if you run them to loose or to tight on the preload they will fail
Not so on the Timken tapered roller bearings

Stanton--what are the "EE"s with the funky solo umlauts doing in the title of your post???

i didn't think anyone knew what umlauts were any more ! are you old [like me] and did you [kinda] pay attention in english class ?

Keys are small ... thumbs are big. Hitting two keys at once changes some of the characters on an bilingual keyboard. Didn't notice till the next day.

I first thought that was Canadien for EHH EHH
