Cyclic clicking coming from right side of my truck while driving

I have been driving around with some really weird consistent vibrations along with what I believe to be a bad rear axle bearing, can anyone help me out? I also have front 1.5" spacers that are going to get replaced with a better quality set as I know they can contribute to any vibrations.

 

Also will be doing a differential service just because it wouldn't hurt, anyone have any idea what oil i should be using?

 

Did you do any work to your rig before the noise started? Was it a gradual thing? Or did it come on suddenly?

 

Have been working on my truck for a while but this came as a small non consistent vibration and grew into a consistent strong symptom, cyclci noise may have been there as well I only noticed it recently

 

Was it there before you put the tires on?

 

Are you feeling the vibration through the wheel or the seat? Having someone else drive while you ride in the bed and listen may help pinpoint noise. As for oil, I like the amsoil severe gear in my diffs.

 

There was a TSB for the rear wheel bearings. My 2010 had the issue, but it was more of a cyclic rubbing sound than a click. Look up the TSB and see if you have the symptoms. I don’t know the TSB number.

 

Apparently it ended up being my trans shifting into overdrive too early and then the RPM is too low from 30-40 miles per hour causing my vibration. Can't really do anything about this which sucks unless anyone has some advice.
