Wheel Bearings

Print

The Toyota Celica models are equipped with sealed bearing assemblies. The bearing assemblies are nonserviceable. If the assembly is damaged, the complete unit must be replaced.

Adjustment



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. All models use a non-adjustable wheel bearing. To determine the condition of the wheel bearing, check the backlash in bearing shaft direction and the axle hub deviation. Maximum for backlash should be as follows:

    Corolla and Echo: 0.0020 in. (0.05mm)
     
    Celica: 0.0031 in. (0.08mm)
