Axle Bearing Making Noise

[Chryco Psycho]

Yes & No
if you do not have the center pin you cannot set the end play , I would far rather do it properly & add the center pin than go to the cheap Green brgs though

Where can I get a center pin?  How do you install it in an 8.75?

[dodj]

There is no pin I'm aware of? Swapped a few rears but never knew anything about a pin?

[RUNCHARGER]

I would check with Dr. Diff. Someone reproduces them but I can't remember who, Dr. Diff is the go-to guy though. I'm not a fan of green bearings either on a car that goes around corners.

Oh, here's one link.

Is your new 3rd member a clutch style sure grip?

Cause they are the only units that use thrust pins... And if your missing thrust pins you buy thrust pins not new bearings...

And now I'm removing the tru-trac I just put in because the guy who helped me said I didn't need it....I'll be doing the same job as you tonight Erik

I haven't heard/read good things about truetrac and 8 3/4 ....... Hope yours is trouble free.

Me to. Locally the Mopar guys seem to really like them?

I'll ask the stupid question,  What's wrong with the green bearings, I've put them in the last few cars we've restored ever since a rear end shop told me they were an improvement  over stock.

[Shane Kelley]

They are a sealed round ball bearing design and work fine for going straight. It's been said they don't handle side loads very well. Like road course curves and driving under those types of conditions.  It's also been said they have durability issues.

I run them myself but can't confirm or deny any of those things. I don't have enough miles on mine yet.

They are definitely not an improvement over stock, they are just cheaper. The 'green' bearings are perfect for something that never see's side loading, like an electric motor driving a pump. But for a car.....well....not designed for the application.

Some explanation of the differences in the types of bearings and their best uses.

I ordered a set of bearings from Dr. Diff.  My R/T is not a daily driver nor is it driven hard in corners, so they should be fine for my application.

[Shane Kelley]

I'm running Dr. Diff axles with his green bearings. I do drive mine hard from hole shots to high speeds.  Not really autocross type driving but I tend to hit the curves pretty aggressive. I guess time will tell.

Just curious. I replaced the center pin in 30 minutes. What made you decide to go the new bearing route instead of just replacing the missing piece?
Fair amount of labor involved in cutting off the old collar etc..
