8 3/4 a body green bearings - 02/14/10 03:10 PM
To install green bearings on my axels does one have to remove the thrust buttoms in the dif .My case is a 849 open with 323 gears.

Re: 8 3/4 a body green bearings - 02/14/10 03:29 PM
when I did mine,I asked Moser about it
they said the 489 with the block in would be ok to run it...
I ran it 8 yrs or so and never a problem out of it,daily driving aleast 90 miles a day
I swaped to a 742 open and took a cold chiesle to the block and broke it in 3 piece and removed it
ran about a yr or so,then had a green bearing go out and start leaking oil
replaced the greens and run it with out the axle tube seals this go round as well...
o-ring on the bearing seals the tube up
so.IMHO..either way will work and end seals are not needed either
but the axle seals are a double protection on the ends against leaking
you have to remove the carrier and ring gear to remove the cross pin IIRC
some do ...some dont...up to you

I also give this idea I have on the bearing failure...
they dont take side loading well from what I have read and been told...
mine was pushing 8-9 yrs at 90 miles a day
I hauled a tow dolly about 200 miles,it had a fishtail motion when empty
wagged my truck the 200 miles back and forth all the way till loaded then towed it like on glass..real smooth and no fishtailing
I think the back and forth did the bearing in, cause of the side loading back and forth
it was bad enuff empty to slow me down from 60 to 45 mph
couple days later it was leaking
I have done lots of hard cornering,dough nuts,power slides,and just plane hammering on it
I think the 200 miles of steady back and forth side loaded them enuff to wear the 8-9 yr old bearing out...
just my experiance with them
my new set is working fine and no leaks with just the o-ring on the bearing...no axle tube seals in this go round

If you are running stock length axles with snap-ring style Green bearings, the thrust button does not need to be removed.

..heh Don.
..some say the green bearings don't handle axial or lateral loads as well as oem,personally i have no experience with them.
why not just use oem,or do green bearings have some advantage?

if you use the conventional green bearings you will have to remove the thrust button?

I don't know if you must remove the thrust button with the first generation, RP-400 Green bearings.
I don't see any reason to run the RP-400 bearing still sold by Mopar Performance.

Hi Al if you run the green bearings there is no worry about the axel end play.OEM bearings there is an adjustment for the axel.

What does this snap ring look like.also what does it do.I thought all I would have to do is slide the axel in place and tighten the 5 bolts and be done with it.

Re: 8 3/4 a body green bearings - 02/15/10 01:12 AM
the snap ring is on the outside of the green bearing along with a o-ring
the flage goes on the axle then the bearing then the lock coller
the bearing slides into the ends of the housing,the o-ring seal in the end cub and goes in till the snap ring is against the flange
now the bear retaining flange bolts to the 5 studs and pinches the snap rear to hold the bearing in place
no endplay adjustment needed
kinda simple once you see the bearing and retaining flange
the roller ball bearings do not like the extrem side loading

It’s so funny; many of these types of things never come with instructions. Yet after the first time you do it you wonder why they would?

Good picture, except the inner (orange) seal is facing backwards.

Re: 8 3/4 a body green bearings - 02/15/10 02:20 AM
you are right, you are keeping the oil in the axle And Cass will get you about the best pricing too.

Unfortunately, Green bearings don't come with instructions. They are easy to install, however. They press on in the order pictured in this thread.

I used a press to remove mine, you can go to a machine shop, a brick and motor parts store, or do a search on some of the shade tree ways to remove and install these as everyone has their own preference.

I bought these bearings with the snap ring. I have Moser ends on my housing, and Moser axles and I could not get the axles to install until I removed the new inner seals from the housing ends. They would hit the seal and push back out a bit. The seals were for sure seated all the way in and they were the very thin bodied seals shown. Just a heads up if you are using a similar combo of parts...

Re: 8 3/4 a body green bearings - 02/15/10 04:43 PM
OEM and Moser housing ends are 2.5" long. If the seals are installed all the way in, you should have at least 1/4" between the lock ring and the seal.
Air gets trapped between the inner seal and the wheel bearing O-ring. This often makes people think the axle bottoms out during installation.

I hoped that was it as well, but the ring was making contact with the seal. The seals were installed correctly, and completely seated. I don't know what is different about my set-up, but it is what it is...

Ok Cass witch ones should I go for.I think I will let a rear end shop install the Axels and center section have a pro do it right the first time.Should I get the green with the snap ring or the green were the thrust buttoms have to be removed,also I need a center gasket pinon seal and the crush washer.Please email me with prices.Also is there anyway to ship through mail.Up here ups hits us with a huge brogage fee.

I recommend my Green bearing maxi-kit. It includes a pair of snap ring Green bearings, as well as all other gaskets and seals you may need for $85. USPS (Postal) shipping to Canada runs $40.
