Green axle bearings

[mickey]

I have a set of green axle bearings which i had planned on using.After reading some posts on these BRG iam not  so sure if they are worth the trouble. My rear end is all apart now and would appreciate any comments before i continue I'am at a stand still.

Well I'm sure if you searched this board you will find some that say don't use them and otehrs that claim they have tens of thousands of miles on them.  So apparently you will never get a real answer.

The main focus of concern with the set-up is the actual bearing.  Stock the bearing is a cone bearing (conical) and the green bearings are just a flat bearing.  The cone bearing is able to handle side loading a lot better than the standard bearing and this is where the debate stems from.

Some people say if you run the green bearings, replace the bearings every 2000 or 5000 miles or something like that.  Others say the bearings are fine the retainer is good and holds the bearing and keeps the side loading down.

I don't know what to tell you.  I ran the green bearings in my street driven Charger for 5 years w/o thinking about them once.  I probably have around 13,000 miles on them.

I use them

I'm using them also in one of my cars although I don't have many miles on them. So far so goood.

they will not last as long But they do work , the biggest problems is either trimming the axles  o rremoving the spacer block to get the axles to fit correctly 

[MyMopar]

How will you know when the bearing is no longer any good?  Any signs to look for?

The picture is getting clearer,well my first thought like so many others was getting away without adjusting end play when swapping gears out,without a hassle.And nothing wrong with my own brgs to begin with. So i just have to make the decision on which direction i go with.

Now i learn trimming end of axles or remove spacer block for these  gr BRGs to work correctly and the probability of them not lasting to long.The old adjuster wasn't that big of a problem.

I have another question or questions? with the gaskets  that came with the green BRGs.For correct depth of the axles would i use just the gaskets that came with the brg only and where would this gasket be used between backing plate and axle and retain my steel gasket on housing flange. I'am thinking this will get away from shaving down axles?
On the oringnal houseing flange and using original brgs  when assembled starting from housing flange outward there is a metal seal/gasket on housing flange, next would be the backing plate, next would be the foam seal/gasket then axle and tighten to torque spec's.

1.What seal/gasket would i use or despose off or keep ,when using these gr brgs and in what order?
2.And i think i have the right order with using original axle bearings are these in correct order?
3. Should i have to use silcone ,these are all new seals/gaskets never used before?
4. what process was used when taking old bearing and retainer of the axle?

What i do know is these gr brg should always be pressed on or any bearing for that matter. not pounded on axle with a pipe and hammer etc  using this process will cause the bearing to be damaged and will wear out the bearing in do time.



For anybody new to these forums on this site this is what makes it such an excellent sourse of information.some answers are either a neg/pos put the person can conclude their own opinion. Thanks to those who repley to the question or put forward information so we can all learn from it.

JUST for thought, there alot of companys out there feeding our hunger for our addiction to mopars. Some products they sell are advertized for us to jump an buy and most products work but some companys  forget to mention the snags some product do have, like these green bearings. These products have been put to the test by knowledgable members of this site, the forgotten snags are quickly learned here. If we had a forum for parts to buy Good/Good with a Snag/Bad or quality products and prices could also be a consideration.  :violin:But seriously a addict of these mopars could make thier own conclusion rather quickly and more of the wiser or knowledgable before purchasing parts.
 Anymore knowledge or imput on this topic is greatly appriciated cheers.

Signs to look for when bearing is no good, heat or noise or just jack up car put a hand on top and bottom of tire and side play and check  for any signs off slack from wore out bearing.

[Chryco Psycho]

typicall the brgs will last 80,000 miles where the factory brg can last 200,000 or more if kept lubed , any in or out play is a sign they are going away
 the diff should have a steel gasket between the brake backing plate & the diff housing & the gasket supplied with the green brg goes between the brg flange & backing plate, , virtually evertime I have used th egreen brgs the axle has been too long requiring the removale of the center spacer or the axles to be trimmed , approx 1/4 between both axles is typical

[mickey]

Chryco with this centre spacer out, i take it is the one in carrier between axles right. what was the purpose of the centre spacer in the first place for(i thought typically when using the adjuster on passenger side axle would move in hitting this spacer thence  spacer slides over hitting  other axle to take up the desired  end play adjusting, correct). And with this spacer out the bearings in the carrier have an adjustor  on each side would that have any effect,extra axle  load on these brgs. thxs trying to get a line  on this.
Has anybody talk to the company that design these brgs to see if they had any complaints or concern with regards to our topic.

[Chryco Psycho]

yes the center spacer puts the load across both axles so the adjuster works
 so with the spacer out the brg has to take all the side load & the axles do not touch the center pin at all

[mickey]

 Thanks, any trouble taking out spacer in carrier. I  have a 489 carrier currently 276 gear, i have 355 ring and pinion for a 489 carrier which i will be changing over, and i have a dana power-lock from a 741 carrier i think will fit in any carrier? So i'll be losing that spacer somewhere in the mix-up.. any tips on getting the old retainer and brg off the axle, iam thinking chesal and hammer on retainer, and some made up puller on brg once retainer is removed. I know the bearing will shatter like 22 bullets if thouched by a chesal or wrap it with a good rag.any suggestion will help...

[Chryco Psycho]

the sure grip will fit any carrier , with the sure grip if it is the 4 pinion clutch type will use buttons instead of the spacer block , so just remove the buttons & you will have the needed clearance , I use a press to install & remove axle brgs , you could chisel or grind through though just don`t cut into the axle

[mickey]

Chryco thanks for the assurance, i can get my hands on a press, but for the life of me, can figure out what type of jeg to use to get it off any suggestions or a picture?, putting it on no probe. cheers

The axels are like 30" long, and they wouldnt fit into my 12ton press (home shop type) with the cross beam all the way down. To get the old ones off, I cut each race and the retainer, in half with a dremel cutoff wheel. Carefully cut thru, but not quite, all the way down to the axel. Once you have it slit, whack the kerf with a chisel.
To get them on, it will fit into the press.
