Chevrolet Sonic Repair Manual: Tires and Wheels Description and Operation (Equipment)
- GM Recommended Tire Balancer
-
Hunter RF33 Road Force balancer or equivalent with the following options:
- Auto Clamp – allows for centering repeatability and prevent damage to the wheel.
- Wheel Lift – helps prevent wheel damage and assists in the accuracy of the placement to the collet.
- Laser System for Weight Placement – for highly accurate weight placement and to verify the morning calibration procedure.
- Integrated Printer – to document the RFV results and VIN for each tire and wheel assembly.
- 20-2472-1 GM Collet and Flange Plate Kit – 11 degree short collets offer better centering and reduce protrusion into chrome-clad wheels, which interferes with proper seating. Flange plates further protect the wheel by placing the mounting pressure at the tapered lug holes.
- Specific Software – co-developed with GM.
Note:
This equipment is recommended to increase repeatability and reduce variation of the assembled product.
- Equipment Maintenance
-
- Spindle shaft and hub face should be cleaned at regular intervals.
- Do not lube the hub face.
- Mounting cones, collets and other mounting devices, should be cleaned,
lubed and inspected for burs.

Machine must be calibrated regularly.
Wheel Weight Cutter
3M wheel weights are made of a unique, flexible and conformable material. Precision cut length weights improve wheel balance and vehicle ride quality.
