Oldsmobile 84641365 HUB ASM,FRT WHL (W/ WHL SPD SEN) <SEE GUIDE/BFO>

The front hub and wheel bearing assembly is an evolution of the worldview in that it is sealed-for-life and therefore can only be replaced in its entirety. To remove it, simply turn the driveaxle nut counterclockwise by one full turn; the wheel lugs should be loosened, the front part of the vehicle should be raised and supported on jack stands. In order to avoid the vehicle running a parking brake should be engaged and rear wheels should be blocked. Take off the wheel, unscrew the nuts of the connection between the stabilizer bar and the control arm, if it is present, and then unbolt the caliper and its bracket from the steering knuckle and pull aside with a piece of wire. If you have ABS model, there is a bolt that should be unbolted and the sensor should be shifted aside. Wrench the disc off from the hub, unbolt the driveaxle nut and get rid of the hub/bearing bolts. To remove the hub/bearing assembly from the driveaxle, there is the use of a puller to loosen it from the splines on the driveaxle as well as the knuckle as needed, as well as tapping it out You need to wrap a rag around the end of the driveaxle for protection of the splines. To install, use a multi-purpose grease on the driveaxle spline, align the hub/bearing over the end of the driveaxle, push it into position and secure with the bolts, tighten to the recommended torque. Secure the driveaxle hub nut and the brake disc and then the caliper and ABS sensor if necessary. Last, bolt the wheel, drop the car and finally round up the lug nuts to the right torque and as a confirmation make sure the driveaxle hub nut is also rounded up to the right spec.

The caliper should be hung with a piece of wire to avoid damaging the brake hose.

Remove the wheel and the brake caliper, and hang it out of the way with a piece of wire. Disconnect the ABS speed sensor electrical connector.

If the hub and bearing assembly are being replaced with a new one, it is recommended to replace the dust seal in the back of the steering knuckle.

Start by loosening the rear wheel lug nuts and blocking the front wheels.

The hub and bearing assembly can be removed by rotating the hub to align one of the holes in the flange with each of the mounting bolts and then removing the bolts.

Use a puller if necessary to draw the hub and bearing assembly off.

The rear wheel should be removed.

The ABS connector should be disconnected.

Raise the rear of the vehicle and support it securely on jackstands.

To install the hub/bearing assembly, ensure that the mounting surfaces are smooth and free of any damage.

To install the hub/bearing assembly, ensure that the mounting surfaces are smooth and free of any damage. Lubricate the driveaxle splines with multi-purpose grease and then fully seat the hub/bearing assembly onto the steering knuckle. Use new mounting bolts to secure the assembly to the knuckle, tightening them to the correct torque specifications. For ABS-equipped vehicles, connect the wheel speed sensor harness connector and secure it to its bracket. Install the brake disc, caliper mounting bracket, and caliper, tightening the fasteners to the proper torque values. Install the driveaxle/hub nut and tighten it to the correct torque specifications. Finally, install the wheel and lug nuts, remove the jackstands, and lower the vehicle. Tighten the lug nuts to the proper torque specifications.

Start by loosening the lug nuts and blocking the front wheels to prevent the vehicle from rolling.

For installation on models with rear disc brakes, transfer the parking brake actuator from the old hub to the new one. Position the hub and bearing assembly on the knuckle, align the holes, and install the bolts.
