you will hear a grinding noise in rear -
find a nice hill - shut engine off and roll in neutral- open drivers door & listen -
u can put car on jack stands - right under the shock mount, so that full weight is on rear spring - making sure that drive shafts are level as if car were sitting on the ground
put in gear & rotate wheels slowly - should hear - be careful when on jack stands

A grinding or "Wiggle" when turning in most cases is the posi clutches sticking in the rear end. The car will feel like it's doing a duck waddle when you go around turns. The simple solution to this is the put a bottle of the rear additive in the car and then find a parking lot and do some figure 8's. This will work the posi additive into the clutch pack and usually brake them free.
How do you tell when your rear bearings are gone... Simple... pull the half shaft back set the spindle, put a dial indicator on the rear spindle flange and then pop it to check the run out of the rear wheel bearings.
0 - 8 thousandths is considered acceptable. However, I like them between 3 and 4 and would never run them at 0. Anything with more play than 8 is toast and needs to come out.

I don't trust or run anything in the rear end except the GM lube and additive.... I don't know anything about Royal Purple, but I checked it out tonight and I don't see where there is any additive in there.. My suspicions is that you need additive and my advice is to find some GM additive, get two bottles, add one to start with and then if the noise continues add another. Do the figure 8's between bottles.

Quick question on this... I'm certain I have one (drivers side) that'll need to be handled here soon. From what I'm hearing, this would be something you'd want to do both at the same time since the other usually isn't far behind.
This is prob. something outside my level of comfort (and I don't have the tools) and time commitment in handling myself. Any ideas on what I should budget to have them both done... ballpark range knowing other stuff might be found that needs to be repaired/replaced?

$349 each is a bargain....I just went thru mine and did all the work myself...Took over 4 months and close to $600.
Be forewarned there will be core charges for any parts that should be re-used but are too far gone to do so.
