Removing Bolt-On Wheel Covers with Center Caps on Steel Wheels If the vehicle has steel wheel covers with center caps, the wheel nuts are behind the caps. To remove, do the following: 1. Pry off the center caps by inserting the flat end of the wheel wrench at the notch on the cap. 2. Use the wheel wrench to loosen the plastic wheel nut caps in a counterclockwise direction. If needed, finish loosening them by hand. The nut caps will not come off. 3. Use the flat end of the wheel wrench and pry along the edge of the cover until it comes off. The edge of the wheel cover could be sharp, so do not try to remove the cover with bare hands. Do not drop or lay the cover face down, as it could become scratched or damaged. Once you have removed the wheel cover, center cap, or nut caps, use the following procedure to remove the flat tire and install the spare tire. 1. Using the wheel wrench, loosen all the wheel nuts. Do not remove them yet. {CAUTION: Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack. 5-86
