Hey guys,I was wondering what some of you think about Green Bearings? Now I know there were two types,the early version being the RP-400 bearing and the second version being the MO-400 with the snap ring.I've heard varying stories about them.Have any of you actually used them? How many miles have you put on with these bearings? I've heard that they don't seem to last as long as the old taper bearings and that they don't withstand cars that do alot of cornering,but it seems most of the newer cars use these types of bearings.Is it the additional weight of our C-bodies that causes premature bearing failure? I see that many of the aftermarket rear brake kits all require "Green Bearings" except for the Scarebird kit,which does not.Is there any advantage to changing over to green bearings just for the hell of it?
 
I have those bearings in 3 of my cars, never had an issue. John.
 
As I understand it, the "green" bearings are for straight line Drag racing and are not good at taking the side load from cornering. Ball bearings aren't made for that type of force.

The stock tapered bearings are pretty good, and are designed for all the stresses of driving. Grease and adjust properly and you're set for 100k miles... Why would you want to change to a weaker bearing??
 
I should add... people do use them and say they have no issues.
 
The "Green" bearings are for normal driving and NOT for drag racing, or any other kind of abuse!!! I have never trusted them. I know how to set preload, so I do not need the "Green" bearing. They are people who want to install and forget about them. That's fine, I guess, for everyday driving. But, I'd rather have the adjustable bearing.
 
Well,everything that I've read about them hasn't been overwhelming.It seems people that have used them don't seem to get too many miles from them before they need replacing.My stock taper bearings are doing just fine,but like I mentioned originally,most aftermarket disc brake kits use the green bearing setup and if I decide to go that route I'd rather not put an inferior bearing in my car that is going to need replacing frequently.
 
It will need replaced, tapered never, use the tapered tighten up endplay and you can you any kit that has floating caliper. I'm guessing you live in a warm weather climate because most new cars and suvs that use those bearings can't make 80,000 without a replacement gm is some of the worst ones s-10 and trailblazers 60-70 consider yourself lucky.
 
I've had green bearings...never liked them. Much prefer a good timken tapered bearing. Learn how to set the end play properly...not hard at all...and you will never have a problem.
 
Why mess with a bearing that has been used on thousands of Mopars without any problems.. Setting the side adjustment is very easy. The greens are not made for axial thrust like the Timkins.
