Default green bearings

I have three A bodies where I installed big bolt axles with Green bearings. I have heard, including im Mopar Action magazine that these bearings fail and have been garbage for over 30 yrs, Any one have any comments on these bearings?

....yes but, they advertise them for race only now. Do you think cornering is a prob? Obviously you have put these under about 450 horse so to me that is pounding on them....also Steve

Tech Question
Ray Block, Columbus, OH, 1992 Dodge Dakota 318

In installment 2 of Savvy Savoy, you said you do not recommend Green bearings for anything other than drag racing while you do seem to be recommending the "sealed cartridge type used on some 1980's ford pickups".

If these have been around since the '80's and are superior to the Green bearings, I'm wondering if my CRS has been working overtime or if no one has actually mentioned them before? Naturally curious which/why that might be?

The aftermarket axle companies I've looked at all offer the Green bearings but not (obviously anyway) the Ford bearings. Sooo, of course, I went with the Green when I swapped an 8 3/4 into my Dakota 6 years ago.

So far so good after 13,000 miles and 1,200 drag strip passes but you make me wonder if (why) I should switch to the Ford bearings anytime soon?

As always...you da man! Enlighten me please.
Thanks, Ray

Ray, the Greens are low-capacity ball bearings...maybe 1/10 the side-load capacity of the stock Timkens. They are fine for drag racing, pretty lousy on the street, and pretty scary if you're into cornering or towing! (Admittedly, I've never personally seen one catastrophically fail, but I've seen plenty get noisy and sloppy).

The Fords are sealed rollers, way better than balls. The reason why you don't see more of 'em is 'cause they require you to weld on custom axle housing "ends". I have featured these earlier in the mag, as a way to dump the C-clips on 8.25 and 9.25" axles.

I also must add that, except that they require more care during assembly (packing with lube, endplay adjustment, etc.) the stock Timken tapered roller setup is about as good as it gets.

Rick

I believe the reason that the Green bearings have become so popular is because people don't understand how to adjust the end play with the factory Timkens. Kinda like going to a hydraulic cam because you don't know how to adjust solids.

I see no need for the Greens unless you're doing a disc brake conversion that calls for them.

Ya, rear discs is the only reason I've seen them mentioned!

There is no doubt that a tapered roller bearing will have more side load capacity than a ball bearing but; A green bearing is not a typical ball bearing, the inner race is two pieces and the outer sides of the races are higher to increase the side load capacity.
This design is used in veirtually millions of front wheel drive vehicles and independent front suspension 4wd pick-ups.

I recently had to replace the front wheel bearings (getting quite noisey) in the wifes PT Cruiser at 75k miles and surprisingly they were tapered rollers. I also had to replace the front wheel bearings in my Dakota 4x4 at 160k miles. They were the double row ball bearings like a Green. They were real noisy but the failure was because of seal failure allowing in dirt and water (I off road on the beach regularly). It was amazing how corroded they balls and races were and the noise was actually less noisey than the PT's bearings which felt fine once out of the car. Neither had catastrophically failed.

Either bearing type can be designed to provide adequate side load.

we circle track with green bearings. we have snapped all five studs off in a wreck, ripped wheels off the axles, and broke axles, yet the bearings still are fine. I have even pressed off the green bearings off the broken axle and installed on new axles, still work fine. If there was side load going on, then you have to short of axles. The center of the axles push on each other, or the center pin I should say.
I have seen many ford bearings go out, and the factory timkens, that is a crappy design. Green for me

Had Green bearings in my 4150lb. '66 Charger for years. Mostly a street car. No problems yet.

Default Green bearings

I've used 4 different sets from different places years ago and all 4 sets got very noisy, I replaced them all with tapered Timkens and never had any problems with them. I will NEVER use a set of Green bearings again! They are not for the street!

I've used them in a drag car w/o any problems. The problem I had w/ the Timkins is the thrust button in the center. Where can you get a replacement for it? I had several units where they were broken or missing.

Years ago the thrust buttons were hard to come by but now just about any Mopar vendor will have them, the new ones are held together by a soloid rivet instead of the old roll pin that broke.
