Removing the Wheel Covers If the vehicle has wheel covers, be sure to use a wheel wrench to begin the process of loosening the plastic wheel nut caps. Once the plastic nut caps have been loosened with the wheel wrench, finish loosening them with your fingers. Removing the Wheel Center Caps To remove a center cap, use the wrench to pry gently at the notch. Do not use a tool that is narrower than the wrench to pry at this notch. Then pry off the cap. Then, using the flat end of the wheel wrench, pry along the edge of the wheel cover until it comes off. Be careful; the edge may be sharp. Do not try to remove the cover with your bare hands. 5-78
