Chevrolet Sonic Repair Manual: Tire and Wheel Balancing (Wheel Pilot Bore Greasing)
- Beginning with MY 2011 vehicle, pilot bore grease should be applied.
- To enable this, grease must be applied to the pilot bore to prevent the wheel from seizing onto the hub.
- Refer to Adhesives, Fluids, Lubricants, and Sealers for pilot bore lubricant part number.
- Do not use any penetrating oils, grease or other lubricants on the wheel studs to aid in removal or installation. Always install wheels to clean, dry wheel studs only.

Only a very small amount of grease should be applied to the inner diameter of the wheel hub pilot hole of the wheel.
