For 2000 models with pulse vacuum hub locks, the hub and bearing assembly is a sealed unit that cannot be adjusted or serviced; if defective, it must be replaced, requiring special tools for removal and installation. To remove the hub lock, six special clips, a hub-lock puller, and a slide hammer are necessary. Begin by loosening the front wheel lug nuts, raising the vehicle, and removing the wheel. Next, remove the brake caliper and disc, install the hub-lock removal clips, and align the puller with the hub lock. After removing the hub lock assembly, unbolt the Brake Rotors splash shield, detach the vacuum line clips, and disconnect the ABS harness if applicable. Remove the hub assembly-to-steering knuckle bolts, tap the hub assembly to break it loose, and pull it off the driveaxle. For disassembly, a special needle bearing puller and slide hammer are needed to remove the caged needle bearing, ensuring not to unscrew the bearing retaining nut. Inspect the hub and bearing assembly for damage, ensuring to replace old O-rings and thrust washers. For reassembly, install the caged needle bearing and lubricate it, ensuring the thrust washer locking tabs are seated correctly. During installation, inspect and replace the main seal if necessary, then install the hub and bearing assembly, tighten the mounting bolts, and reconnect the vacuum line. For models without pulse vacuum hub locks, the sealed wheel bearings must be replaced if defective. The process involves similar steps of removing the wheel, brake components, and driveaxle/hub nut, followed by detaching the wheel hub from the steering knuckle and reversing the process for installation, ensuring to use a new driveaxle/hub nut.
