Q: How to remove and replace the front Wheel Hub on Mercury Cougar?
A: The front wheel bearings are a single unit hub design and are pre-greased, sealed and require no maintenance. The bearings are pre-set and cannot be adjusted. If a bearing replacement is required, the hub and bearing assembly must be replaced as an assembly. To remove, first loosen the wheel lug nuts, apply the parking brake and raise the vehicle. Support it securely on jackstands placed under the frame. Remove the wheel. Next, remove the grease cap from the hub and discard it. Then, remove the brake caliper and secure it with wire so that it does not interfere with the spindle. Remove the brake disc. Remove the hub nut and discard it. Finally, remove the hub and bearing assembly. If the hub assembly is not easily removed by hand, use a puller. Note: If the assembly cannot be removed by hand, use a two-jaw puller. Don't immerse the hub unit in solvent. It is packed with grease at the factory and to do so would ruin it. To install, simply reverse the removal process. Tighten the hub nut to the torque.
