2008 Chevrolet HHR LT, 2.4 P, AutomaticSECTION Installation Procedure
WARNING: This page is about a different car, the 2011 Chevrolet HHR. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants must be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.

  1. Using the J-42450-A  Wheel Hub Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the hub/axle flange.
  2. Using the J-41013  Rotor Resurfacing Kit, thoroughly clean any rust or corrosion from the mating surface of the brake rotor.
  3. Inspect the mating surfaces of the hub/axle flange and the rotor to ensure there are no foreign particles or debris remaining.
