Checking for wear on the knuckle of the upper CA is not hard with an SLS. Jack up the rear of the car, take out the spare tire (remove ign key to be sure the pump doesn't kick in) and release the airlines going into the accumulators slightly so they bleed off pressure. Grab the rim on either side once the pressure has gone and see if it moves. My 4.8 which I checked last weekend had no movement but the 4.4 was a disaster area. Both upper CAs were completely shot.

I have the whole rear shooting match on order, including new bearings, to fix this.
