Went outside and jacked up the passenger side again. Put my hands at 3/9 6/12, tried to shake side to side and I got nothing. There is no howling indicating a bad bearing. Only howling I get is gear whine on deceleration. The wheel/rotor assembly seems to move in-and-out as a unit. The axle housing didn't shift, no play in the shock/spring assembly either. I would also say its not really a 1/16th of play, less than that. Seems like a worn c-clip according to you description.

There is a Chevrolet dealer just down the street ha. They said one bottle of LSD additive is $20.84, gear lube (85w-90) is $35.80 per quart. They didn't have any c-clips in stock but they are just over $8.18 each (may have to have them order one). AAP has Mobile 75W-90 for $11 per quart, probably go with that.

I am thinking of ordering c-clips off of rockauto but they didn't have them listed under my car... The only c-clips came up for older Camaros using 8.5" 10-bolt and Pickup/Suburban as part #81050. They are listed for $2.21, far cheaper to order online instead of driving 2hrs to a dealer that has them. Are they the same for all 10-bolts?

Thanks.
