Cheers mate. Appreciate that.
I'm confident I can do it myself but time ( the self employed mans enemy) and lack of tools etc is a major factor.

And you want green bearings

YES!!! My axle was built by a very reputable firm in the U.S. and the crappy bearings they supplied pi55ed out fluid I put Greens in, no more leaks

I've heard that green bearings don't stand up well to cornering ?
Basically drag use only ?

Always used green bearings, never had a problem. They have always been fitted as standard on Ford axles, and pretty much everything these days uses a non tapered bearing at the rear.

Here is a copy of a letter written to Bearing technology I found.

The question is whether or not the RP400 bearing kit for Mopar 8-3/4" axles is suitable for street car applications. There has been a lot of discussion that since your catalog lists it under "Racing" that racing is the only application. Some have also said that the RP400 doesn't have enough lateral retention for street use. Others have said that they have several thousand miles of street use with the RP400s in their axles and have encountered no problem. Can you clear up the issue for me?

Dear BTL,

I received your question about the RP400. I'll try to answer this to the best of my ability. The original intent of the RP400 designed by the Green Bearing Company was meant as a replacement for the original taper bearings in the rear end of Chrysler / Mopar applications. It was made for street vehicles, as were all of Green's automotive bearings. Over time these products became favorites of custom axle manufacturers such as Moser Engineering, Strange Engineering and Mark Williams Enterprises. Green, being a job shop, manufactured a multitude of bearings for these outfits and started categorizing them as "Racing" bearings due to the fact that the products were becoming popular in that application.

There are a lot of these bearings on the road in both street applications as well as on track applications. As far as performance, all I can say is that these have been a staple in our product line with no revisions / issues for a long time. The experts on the performance of the product in various applications would be Moser or Strange. If you would like to contact them, you have to ask specifically for the RP400 with the fixed flange because there is a modified version (MO400) which was designed by request for Moser and has a slide over flange with a snap ring retainer.

You can visit www.moserengineering.com or call 260-726-6689 for more information.

Thank you for your interest in our products.

And I have them in mine.

Good question.
I do not understand the current fascination with green bearings.
Maybe it is because they are cheap and easy to install.

However, for road use, I am not convinced.

The standard Mopar set up (using taper Roller Bearings) whilst needing adjustment (which is not the end of the world) would seem to be a better solution wher side loads are involved - i.e. emulating Bo Duke on roundabouts.....

I would like to see other people's views and knowledge on this as I am about to change some axlew shafts and I am leaning (no pun intended) towards the standard taper roller bearing set up...

Thanks.

I was obviously told B/S then !!!!
I know a lot of people on here like them but thought I'd post up what I had been told.

You beat me Pete.
So perhaps there is some truth in what I heard then ???

Over to the experts !!

Did you read my post?

Timing issue on my Post....

Good to hear the feedback to date...I have used them and not encountered a problem....

i can not honestly see a problem using a green type bearing most solid axles use this type bearing as standard equipment, i think to much gets read in to the fact the taper type would appear to work even harder/better when loaded up, ie in a corner etc only time to swap em out is if your tapers are knackered i reckon

Do you believe everything you read ???

Heard a couple of guys discussing green bearings so asked what I heard

Well do you believe everything people tell you?

Carl wrote:Well do you believe everything people tell you?

No ....... That's why I asked if what I had heard was true !
A letter from a manufacturer/ supplier verses the people who use them !!!
