  Q:

  How Is the Rear Axle Pinion Bearing Preload Reset and the Differential Seal Replaced During Service on Mazda B2200?

  A:

  The service procedure includes careful resetting of the pinion bearing preload. The first step is to safely raise the vehicle and support it. Next, remove the wheels and brake drums. Mark the driveshaft and axle companion flange to ensure they are reinstalled correctly, then remove the driveshaft. Using a torque wrench, obtain the value of the torque required to maintain the pinion rotating through several revolutions. Using a suitable tool to hold the companion flange, remove the pinion nut. Mark the companion flange concerning the pinion shaft for later reinstallation. Make use of a suitable puller to pull off the rear axle companion flange and use a small prybar to pull out the seal from the carrier. When installing, ensure no burrs are present on the pinion shaft splines. Apply grease to the pinion seal lips and install using a seal installer. Check the sealing surface of the old companion flange for damage. If damaged, replace with new flange. Apply grease to the splines. Align the markings located on the flange and the pinion shaft at the time of assembly. Furthermore, do not hammer or power in the companion flange. Install a new nut on the pinion shaft while holding the companion flange tight. Tighten the nut on the pinion and rotate the pinion at least occasionally to ensure the bearings seat properly. Take the torque preload reading frequently until the original preload reading is achieved. The pinion nut should never be backed off to reduce preload. If a reduction is necessary, a new collapsible pinion spacer and nut shall be installed. To finish the job, put the driveshaft back in and check carrier fluid level before lowering vehicle.

  Q:

  How to remove and install Differential Seal on Mazda B2200?

  A:

  To remove and install parts on pickups and MPVs, first raise and support the front end on jackstands then matchmark and remove the driveshaft, the wheels and the brake calipers. Determine the rotational torque of Differential with an inch lbs. Utilize a torque wrench on the companion flange nut to read. To remove the companion flange, hold the companion flange to stop it from turning and remove the locknut and then use a puller. Using a center punch, you can damage the seal in order to pry it out. After this is done, apply sealer to the outer edge of the new seal. Drive the new seal in place using a seal driver. And make sure to coat the seat lip with clean gear oil. Before installation, apply chassis lube on the companion flange, install and tighten nut until previously noted rotational torque is achieved, and do not exceed 130 ft. lbs. Finally, reinstall the driveshaft and replace any lost gear oil. For the Navajo, disconnect the negative battery cable and safely elevate the vehicle so the axle drops for clearance. Detach the rear wheels and brake drums so they do not drag on the axle. Mark the companion flanges and U-joints for proper reinstallation, and then remove the driveshaft. Using an inch pound torque wrench, measure the torque on the pinion yoke nut to allow differential rotation. Record this measurement. Use a suitable tool for holding the companion flange and remove the pinion nut. Place the drain pan under the differential and clean around the seal. Mark the yoke-to-pinion relation. Using a 2-jawed puller and a small prybar for the seal, remove the companion flange. Make sure the oil seal bore is completely clean. Check that the installation depth is correct using the correct seal driver. Drive the new seal in while coating the seal lip with clean waterproof wheel bearing grease. To install the yoke, apply a little wheel bearing grease on the splines, and then align the matchmarks and hammer the yoke onto the pinion. Put in place a new nut on the pinion; hold the yoke with a holding tool and tighten the pinion nut while taking frequent turning torque readings until the original preload reading is attained; making an adjustment as necessary, do not back off the nut to reduce the preload. Using the matchmarks, reinstall the driveshaft, torque the nuts to 15 ft-lbs, lower the vehicle, and connect the negative battery cable.
