231546-1 – Balance Weigths – Weight 0.43

231546-1 -- 0.43 oz Balance Weight
Lightest in the 231546 series, for light primary correction on passenger cars and light trucks.

The 231546-1 at 0.43 oz is typically a primary correction weight for passenger car driveshafts and light-duty applications where the overall shaft mass is lower and the imbalance forces correspondingly smaller. Vehicles showing vibration at 60-80 mph on a freshly rebuilt driveshaft often need corrections in the 0.3-0.6 oz range -- the 231546-1 addresses the lower end of that bracket.

Cross-reference: Spicer 231546-1. Always run the completed assembly on a balancing machine after welding the correction weight -- the welding process itself introduces a small mass change and can shift the correction plane slightly from the calculated position.
