  Q: Are the left and right rear Axle Shaft, Axle Shaft Seal and Wheel Bearing, and what is the proper procedure for their removal and installation on Mazda 929?

  A:

  The left and right rear axle shaft cannot be changed, as the left one is shorter than the right and it is not recommended to take them all out at the same time. Start by taking off the wheel cover and the lug nuts and lifting the back part of the automobile and resting the axle housing on jackstands. Get the lug nuts unscrewed and the wheel unscrewed and then the brake assembly. Loosen the nuts that hold the backing plate of the brakes and the retainer to the axle housing, and then pull out the axle shaft by using a puller. To install, grease the lips of the oil seal and fit the oil seal into the axle housing. Check the axle shaft end-play on all models except GLC by temporarily fitting the brake backing plate on the axle shaft, a measurement of the depth of bearing seal and width of the bearing outer race, and calculating required shims. Take the backing plate out and apply sealer on the back axle surfaces and replace the backing plate. Plug the rear axle shaft, bearing retainer, gasket and shims through the backing plate into the axle housing ensuring that the splines on the differential side gear align with those of the axle shaft. Lastly, put the wheel and lower the car. Use any 4WD model, upraises the rear part of the car, empties the lubricant at the differential, takes off the rear wheels, loosens the wheel hub locknut when the brakes are applied. Record the relationship of the Driveshaft flange to the differential, loosen the nuts and washers that hold the driveshaft together and loosen the lateral and trailing links to the rear axle hub. Reduce the driveshaft flange of the differential and detach the splined end of the wheel hub, with a hub puller, where needed. Unscrew and take off the rear axle assembly on the shock absorber support. The wheel hub and disc plate of the knuckle will need to be pressed and the bearings and oil seals replaced by matching them and supporting the wheel hub on V-blocks. Install special equipment to press out the outer bearing and oil seal of the hub then use it to press out the inner oil seal and push the bearing races out. Install new races, bearings and seals, making sure that there is proper preload adjustment using a special tool. Put the components back and tighten the required bolts in place and fit in the rear wheels. In the model 929, raise and support the rear, take the wheels off and uncrimp the nut of the rear axle. Indicate the relationship of the driveshaft flange, unbolt the driveshaft and remove the caliper including its support. Check before unscrewing the support assembly of the rear axle/hub, remove the rotor disc, the parking brake assembly, and de-connect several links. To change the oil seal and bearing, press the axle flange with the hub to pull out the oil seal hub and press another bearing into the hub. Put the components back and tighten the required bolts in place and fit in the rear wheels. In the case of the RX-7 models, the rear wheel lug bolts should be loosened, then the car should be raised up and supported and the wheels need to be removed. Take off the parts of the brakes, disconnect the backing plate and take off the axle shaft assembly. Install a bearing separator and press and be careful of the new retaining collar and oil seal which should be correctly installed. Install the axle shaft and components in reverse order making sure that all connections are tight.
