I may be insane but... Is that a remnant of a wax blob...indicating where the weight went?

Actually, grease paint, but yes, that is the mark that was determined to place the wheel weight.

I work in the paint shop at the Ford KC plant as a supplier. A few years back, we had some warranty issues with yellow spot on units. Started to do some backtracking and the grease paint (using yellow titanium dioxide) was being applied too heavy and was flinging off the wheels as it was going thought its 'road test'. The paint, although cured, was still fresh and getting stained. We saw staining from storage additives from gasoline too.

I saw a question about the sequence number... I heard someone tell it a while back and I know it holds true today. When we have a issue with a unit in the plant, we always refer to it by the 4 digit sequence number. Mind you, there are 7 digits in the sequence, but we only use 4 because a unit a sequence number 10000 old should not be in the plant!! i.e.-- 204 8647 would be yelled out as sequence # 8647.

Actually, that's the remains of a wax blob, not grease paint; GM didn't use grease paint. The Micro-Poise wheel/tire balancing equipment used color-coded wax dots dropped on the tire adjacent to the rim flange in the balancing station to indicate to the downstream weight-apply operators what size weight to use and where to apply it. I worked with the GM/Micro-Poise balancing systems for many years in Chevrolet assembly plants when I was a Production Superintendent.

John: would the "downstream" guys re-balance the wheel after applying the weights @ the grease blob, or just assume the first guy fed them the correct weights?

The guys applying the weights sat right next to the roller conveyor where the wheel/tire came by horizontally. They had color-coded bins of weights between them and the conveyor, and when the wheel/tire stopped in front of them, a colored light came on (in addition to the colored wax dot on the tire) that showed them which weight to apply. When they released the wheel/tire after applying the weight, it went directly to the install point on the main line.

If the balance station detected excessive weight required to achieve balance, the conveyor kicked that wheel/tire out and sounded a buzzer for repair. A repairman then took the out-of-spec wheel/tire to a stationary mounter, broke it down, rotated the tire 180* on the wheel, re-inflated it, re-balanced it, and sent it to the line.
