The PT Cruiser is equipped with a sealed hub and bearing assemblies. The hub and bearing assembly is non-serviceable. If the assembly is damaged, the complete unit must be replaced.
Removal & Installation
- Before servicing the vehicle, refer to the Precautions Section.
- Remove the steering knuckle and hub and bearing assembly.
- Remove the wheel lug stud from the hub flange, using a C-clamp and Adapter Tool 4150A.
Rotate the hub to align the removed lug stud with the notch in the bearing retainer plate.
- Rotate the hub so the stud hole is facing away from the brake caliper lower rail on the steering knuckle.
- Install 1 / 2 of a Bearing Splitter Tool 1130, between the hub and the bearing retainer plate. The threaded hole in this 1 / 2 is to be aligned with the caliper rail on the steering knuckle.
- Install the remaining pieces of the bearing splitter on the steering knuckle. Hand-tighten the nuts to hold the splitter in place on the knuckle.
- When the bearing splitter is installed, be sure the 3 bolts attaching the bearing retainer plate to the knuckle are contacting the bearing splitter. The bearing retainer plate should not support the knuckle or contact the splitter.
Place the steering knuckle in a hydraulic press, supported by the bearing splitter.
- Position a driver on the small end of the hub. Using the press, remove the hub from the wheel bearing. The outer bearing race will come out of the wheel bearing when the hub is pressed out of the bearing.
- Remove the bearing splitter tool from the knuckle.
- Remove the 3 bolts mounting the bearing retainer plate to the steering knuckle.
- Place the knuckle in a press supported by the press block. The blocks must not obstruct the bore in the steering knuckle so the wheel bearing can be pressed out of the knuckle. Place a driver on the outer race of the wheel bearing, then press the bearing out of the knuckle.
- Install the bearing splitter on the hub. The splitter is to be installed on the hub so it is between the flange of the hub and the bearing race on the hub. Place the hub, bearing race, and splitter in a press. Use a driver to press the hub out of the bearing race.
- Use clean, dry cloth to wipe and grease or dirt from the bore of the steering knuckle.
- Install a new wheel bearing into the bore of the steering knuckle. Be sure the bearing is placed squarely into the bore.
- Place the knuckle in a press with a Receiver Tool, C-4698-2 supporting the steering knuckle.
- Place a driver tool on the outer race of the wheel bearing.
Press the wheel bearing into the steering knuckle until it is fully bottomed in the bore of the steering knuckle.
NOTEOnly the original or original equipment replacement bolts should be used for mounting the bearing retainer to the knuckle. If a bolt requires replacement when installing the bearing retainer plate, be sure to get the proper type of replacement.
- Install the bearing retainer plate on the steering knuckle.
- Install the 3 bearing retainer mounting bolts. Tighten the bolts to 21 ft. lbs. (28 Nm).
- Install the wheel lug stud into the hub flange.
- Place the hub with the lug stud installed, in a press supported by an Adapter Tool C-4698-1 and press the wheel lug stud into the hub flange until it is fully seated against the back side on the hub flange.
- Place the steering knuckle with the wheel bearing installed, in a press with special Receiver Tool MB-990799 supporting the inner race of the wheel bearing.
- Place the hub in the wheel bearing, making sure it is square with the bearing.
- Press the hub into the wheel bearing until it is fully bottomed in the wheel bearing.
- Install the steering knuckle and the wheel.
- Check and/or adjust the front alignment.
