Axel bearings.

[loco440]

Looks like the bearings on my 8 3/4 axels are no good (wheels shudder on rotation),who supplies good ones and what are the best for this application and are there any tricks to fitting them?

[Chryco Psycho]

make sure the housing is not damaged & the brgs fit tight in the housing
 try to get Tapered roller brgs , it means cutting off the factory ones & pressing on new ones to prevent damage to the end plates but worth it over running the Green replacement brgs

[loco440]

Thanks for your help Chryco,now what i need is part numbers of the tapered bearing to hopefuly order a set through my bearing supplier,these parts are very hard to obtain off the shelf in Australia.

loco, I'm talking over my head as I have no experience with bad rear bearings so please defer to someone with experience 1st BUT the shudder you refer to is something I have observed in the past when spinning the rear wheel. I have no idea what causes this but there were no issues with the rear end.
  As for replacement parts most of our parts stores list a replacement set with bearings, seals & cups.

Make sure that your axle end play adjustment isn't causing your shake first. Too loose is BAAADDDD!

brilliant Rob,great info,checked the adjuster and found it was a too loose,bearings ok after a relube.

[Chryco Psycho]

Great Catch Rob
the tapered brgs rarely fail

[ShelbyDogg]

Glad to hear that you fixed it without having to change those bearings.   When those bearings are too loose, you can hear it by pushing on the side of the car on the rear fender, and rocking it back and forth.

IF you do need bearings the best thing is the newer sealed bearings, It eliminates the adjuster on the left shaft. It is a complete kit to do one assembly 8 3/4 or Dana. c-c members get 10% on most items

Aren't these the same as the "Green" bearings, or are they tapered roller bearings?

[mopardave]

These are the sealed green bearing. not tappered

Do not use GREEN BEARINGS if you want your car to survive on the street. They will come back to bite you in the middle of nowhere. Those are for drag racing only. They do not have the surface area of the roller bearings on the tapered race.

[mopardave]

We have heard of that , of being only for drag racing, we have sold alot of these bearings and haven't heard of any complaint. This is the same bearing that everyone else sells. I would have to check into that.

[Chryco Psycho]

I am also not a fan of the sealed green brgs & prefer the tapered roller brg where possible

[mopardave]

I have put a set on my challenger and my wifes roadrunner and haven't had any issues, The challenger was done about 8 years ago and have out about 5000 miles on them. no issues.
