I want to do a couple of tests with my rearend regarding the vibrations.

Question is can I remove the axle shafts and spin the carrier assembly(with fluid) to see if the vibs go away?
And if the vib is still there can I pull the carrier assembly and just spin the pinion?

Basically I just want to run it up to 70mph at the most 2 times.

Right now I noticed the drivers side outer axle bearing is starting to make noise when turning.
I doubt its the cause of the vibration though!
