  Q: How to check and service vehicle wheel bearings on Mazda MX-6?

  A:

  With the vehicle securely supported on jackstands, spin the rear wheels to check for noise, rolling resistance, and free play. Grasp the top and bottom of the tire and move it in-and-out; if it moves more than 0.005-inch, the bearings should be checked and replaced if necessary. The front wheel bearings require disassembly of the front hub for servicing, while the rear wheel bearings can be serviced as routine maintenance. To repack, raise the rear of the vehicle and support it on jackstands, then remove the wheels. Use a chisel and hammer to dislodge the grease cap, remove the hub nut (which should be discarded), and pull the hub assembly out slightly before pushing it back to remove the outer bearing and washer. Pry the inner bearing seal out with a screwdriver, clean all parts with solvent, and inspect the bearings for defects. Use high-temperature wheel bearing grease to pack the bearings thoroughly, apply grease to the spindle, and place a small amount inboard of each bearing race. Install the grease-packed inner bearing and a new seal, lubricate the seal lip, and place the hub assembly onto the spindle. Install a new spindle nut and set the bearing preload by tightening the nut to the specified torque, rotating the hub, loosening the nut, measuring the torque at which the hub starts to turn, and then tightening the nut to the appropriate resistance. Crimp the collar of the nut into the spindle groove, pack the cap with grease, install it, and finally, reinstall the wheels and lower the vehicle.
