  Q: What does maintenance cover for rear wheel bearings on Mazda 929?

  A:

  On front wheel drive cars, the only bearings that have to be lubricated periodically are the rear wheel bearings, covered by maintenance. Mazda does not insist on periodic lubrication of rear wheel bearings on rear wheel vehicles. Rear wheel bearings that are applicable should be repacked in lithium grease (NGLI No. 1) after every 30,000 miles (48,309 km) or 30 months, whichever is earlier. To adjust end-play of 1983-89 626 and MX-6 end-play, raise and support the vehicle, remove the rear wheel, disconnect the caliper assembly (where equipped) and measure dial indicator gauge of end-play of wheel bearing. End-play must be 0.008 in. (0.2mm); change a wheel bearing should it be necessary. To install a wheel, stake the locknut tab where the 0.08 in. (2mm) or more sticks out of the groove in the spindle, re-install caliper assembly where necessary, and install the wheel. In preload adjustment of 323 models, elevate and hold the car, take away the rear wheel, dust cap, and tighten the locknut to 18-21 ft. lbs. (24-29 Nm). Determine the oil seal drag with a spring scale and sum its value to the given value of 0.6-1.9 lbs. (2.6-8.5 N) to have the standard bearing preload of 1.30-4.34 inch lbs. (0.15-0.49 Nm), and adjust the locknut as required. Snap locknut tab, place the dust cap, and fit the wheel. To remove and install, raise and support the vehicle, get the rear wheel and grease cap off, raise the staked part of the hub nut on which the nut must be discarded. Unassemble the brake drum or disc brake rotor assembly, part the grease seal of the brake drum or rotor, and take away the snapring. Insert the new wheel bearing into the brake drum or rotor, grease the new seal lip with grease and then screw the seal into place. Install a new locknut, install the brake drum or rotor to the wheel spindle, and tighten it up to specifications. Check the end-play of the wheel bearing, it must not be more than 0.008 in. (0.2mm) and stake up the locknut, fit the grease cap and tighten the lug nuts to a minimum of 65-87 ft. lbs. (88-118 Nm). Provided that it is needed, repeat it with the other rear wheel and lower the vehicle.
