  Q: How to perform removals and installations for rear Axle Shaft, Axle Shaft Seal and Wheel Bearing on Mazda B2200?

  A:

  Removals and installations To carry out removals and installations, you should put the jackstands in place to support the rear end up and then remove the wheel and brake drum then the brake shoes and parking brake cable retainer. Disassemble and disconnect the brake lines at the wheel cylinders followed by removing the bolts which hold the backing plate/bearing housing and sliding the Axle Shaft out of the axle housing without damaging the oil seal. In case of damage of the seal, a slide hammer and adapter should be used to replace it. Take out two overlapping plate bolts at right angles to each other, grind the bearing retaining collar until near 5mm remains, and snap the collar off with a chisel, taking care not to spoil the shaft. A press or a puller is used to remove the hub and bearing assembly, the bearing and seal are removed off the hub with a drift being tapped on the race. Inspect all components of wear or damage and replace both races where one is replaced and replace the bearing and seals as a set. To install, the outer race is pressed using an arbor press and the inner race forced into place. Wipe the hub with lithium-based wheel bearing grease, pound a new oil seal into the axle bearing-housing, and a new spacer into the shaft with the greater plain surface side up. Replacement of the seal in the hub, pack bearings grease-filled, and forcefully fit the assembly (hub and bearing) on to the shaft. Install the new collar onto the shaft with the recommended press pressure of between 9,240-13,420 lb. by observing that the bearing plays with a dial indicator and if needed, Shims are applied to adjust the bearing plays. Install the other sleeve, and torque the backing plate bolts and re-check the play. Lastly, put in the brake drums and wheels and bleed the brake system. In the case of the Navajo model, the negative battery connection should be disconnected, the vehicle raised, the rear wheels and brakes drums should be taken off, and the lubricant in the rear axle should be drained. On axles other than 3.73:1 or 4.10:1 ratios, loosen the differential pinion shaft lock bolt, and pinion shaft, push the axle shafts towards the center to dislodge the C-lockwasher, and take out the axle shafts. To remove the pinion shaft lock bolt in case of 3.73:1 and 4.10:1 ratios, push the pinion shaft out of the slot and then remove C-lockwasher and the axle shaft. Removal of bearing and seal To remove bearing and seal, use a bearing and seal remover with a slide hammer. Installation To install, lubricate the new bearing and press in the housing bore, rub lubricant between the lips of the axle shaft seal, and fit a new axle shaft seal. Slide the axle shaft into the housing taking great care to avoid breaking the oil seal, and connect the splines to the side gear. Install the C-lockwasher, and extract the shaft outboard and install the differential pinon shaft over the case and tighten the lock bolt. Wipe down the area of gasket mountings, put silicone sealant, cover and screw in the bolts. Add lubricant until it is 14 in. below the filler hole and put in filler plug.
