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.
- The dimension between the wheel and hub has been tightened in order to reduce mounting variation that results in 1st order tire variation. Only a very small amount of grease should be applied to the inner diameter of the wheel hub pilot hole of the wheel. Do not apply it to the entire pilot hole of the wheel or to the wheel bearing flange.
