So I found a new problem with my front axle on my cummins (dana 60 I believe).

Originally, I removed the vacuum actuator 4by4 engagement system and upgraded to a Posi-lock axle engagement system which does the same thing but you control 4by4 axle engagement with a cable. I did this because it took forever to engage to 4by4 and other various reasons.

So lately I've been noticing a buzzing / vibrating kind of sound coming from my front end. I spent a lot of hours yesterday trying to locate it and found the noise went away when I engaged my 4by4.

It appears that my two splined shafts, where the 4by4 engagement fork is, are rubbing together causing this to happen. There was some wear starting to be visible.

What I want to know, is there a bearing that commonly goes or a bushing that might have worn out to cause this??

I adjusted my posi-lock rig so there was NO way the shift fork was somehow making contact with the other splined shaft (even flipped the fork backwards so the collar was as far over as possible).

Any ideas shoot them out there! Thanks

 

Hmm, mine is doing the opposite. Where it growls in 4x. But I've not heard of the two shafts actually grinding on each other like that. I've not heard of the bearing failure causing that either. That is an odd one for me.

 

There is a bushing that goes between the two shafts.

 

K that would make sense, last time I looked in there that bushing that your talkin about did look a little worn.

I ordered a new inner axle bearing in case it turns out to be that, I'll order in a bushing too.

Thanks! ... now I got to find out how to tear that dana 60 apart....
