Q: How to replace the rear wheel hub on Buick Lucerne?
A: Simply jack the vehicle upward and take away the tire and wheel then brake rotor for easy access to the wheel bearing/hub. Before removing the wheel bearing/hub lower you need to disconnect its electrical connector and remove both its retaining bolts. Clean both the Control Arm and hub bore after taking away the brake shield from the lower Control Arm for new part installation. You should install the brake shield onto the Control Arm and fasten the wheel bearing/hub according to our service precautions. Put back the wheel bearing/hub electrical connector while torquing the wheel bearing/hub retaining bolts to 68 n.m (50 lb ft). Complete the job by placing the brake rotor back then reinstalling the tire and wheel before lowering the vehicle.
Q: How to replace the front wheel bearing and wheel hub on Buick LeSabre?
A: Place the vehicle on a lift at a frame height that lets control arms rest loose as you begin wheel bearing and hub replacement. Take out the wheel and tire set from the drive axle before preparing this space for maintenance. Stick a drift punch or screwdriver into the brake caliper and rotor to secure them and remove the wheel bearing nut then the rotor. Unplug the abs sensor and detach its clip from the dust shield. Remove all wheel bearing/hub retaining bolts to replace the hub assembly as one unit. You need the j28733-b front hub spindle remover tool to dismount the wheel bearing and hub unit from the drive axle before removing it from the Steering Knuckle and then taking off the dust shield. Wipe all surfaces on the knuckle mounting face including the bore and chamber to ready them for the new bearing. Prevent damage to the abs sensor wire when installing. Take off its plastic protector and keep both the knuckle and hub away from direct contact with this wire. Fit the wheel bearing/hub onto the drive axle by adding a thin grease coating to the knuckle bore then thread in the retaining bolts and torque them to 95 nm (70 ft. Lbs.). Fasten a fresh drive axle nut that pulls the wheel bearing/hub toward the Axle Shaft then plug and fasten the abs wheel speed sensor as planned. Place the brake rotor onto the spindle but keep it from spinning using a drift punch or screwdriver. Tighten the drive axle nut gradually to achieve a torque setting of 160 nm or 118 ft. Lbs. Slowly lower the vehicle after installing its tire and wheel assembly.
