Page 1 of 6 HUB & WHEEL BEARINGS (WITH PULSE VACUUM HUBLOCK) DO NOT attempt to repair hub and wheel bearing assembly. Removal DO NOT remove hub lock assembly by prying on hub lock legs. This can crack or break hub locks, causing vacuum leaks. 1. 2. Raise and support vehicle. Remove wheel and tire assembly. Remove brake caliper, and wire to underbody. Remove brake pads and caliper anchor plate. Remove rotor. Install Hub Removal Clips (205-404). See Fig. 4. Install Hub Puller (205-405) over hub removal clips. See Fig. 5. Align hub puller with 3 slots in hub lock. Tighten set screw finger tight. Connect slide hammer to hub puller. Using slide hammer, remove hub lock. Remove and discard hub "O" ring. Remove brake rotor shield. Pull out axle shaft end slightly. Remove axle shaft circlip. Disconnect vacuum hose from hub assembly and remove it from frame. Disconnect anti-lock sensor connector, and remove wire from frame (if equipped). DO NOT allow axle shaft to rest on steering knuckle main seal. Main seal damage can occur. NOTE: Hub and wheel bearing assembly is a slip-fit design and should not require a puller for removal. 3. 4. Remove and discard tie rod cotter pin. Remove tie rod nut. Using Pitman Arm Puller (T64P- 3590-F), separate tie rod end from steering knuckle. Remove 3 hub and wheel bearing mounting bolts from behind steering knuckle. Remove hub and wheel bearing assembly. Secure axle shaft to frame. Check hub and hub bore. If any dirt, metal shavings, moisture or corrosion is found in hub or hub bore in steering knuckle, replace vacuum valve hub lock. See VACUUM VALVE HUB LOCK. DO NOT loosen or remove large hub and wheel bearing assembly nut. Removal of large nut can cause loss of wheel bearing preload and severe damage to hub and wheel bearing assembly. 5. 6. Remove and discard wheel bearing "O" ring and thrust washer. Place hub and wheel bearing assembly in a vise. Using Bearing Cup Puller (T77F-1102-A) and a slide hammer, remove caged needle bearing. Check hub. If hub has excessive metal particles present in axle shaft bore, vacuum system must be flushed out and tested for correct operation. See wheel end vacuum leak test. See WHEEL END VACUUM LEAK TEST under ADJUSTMENTS & INSPECTION. Ensure bearing preload nut and bore slots are aligned. If slots are not aligned or are damaged, replace hub and wheel bearing assembly. Check axle shaft bore for scoring and excessive wear. Check needle
FRONT SUSPENSION - 4WD TORSION BAR -2000 Ford Ranger bearing bore for scoring, blueing and excessive wear. Check wheel hub sealed bearing for excessive looseness or binding. Page 2 of 6 Fig. 4: Installing Hub Remover Clips
Page 3 of 6 Fig. 5: Installing Hub Puller Installation 1. 2. 3. 4. 5. 6. 7. 8. Install NEW wheel bearing "O" rings. Wheel hub and bearing are not repairable. Bearing preload cannot be readjusted. If bearing retaining nut on hub and bearing is removed, install NEW hub and wheel bearing assembly. Coat cage needle bearings with Ford High Temperature Wheel Bearing Grease (E8TZ-19590-A). Install cage needle bearings with stamped part number on bearing race facing up. Using Needle Bearing Replacer (205-402), Driver Handle (T80T-4000-W) and hammer, install cage needle bearing until cage needle bearing replacer bottoms out against hub and wheel bearing. Measure cage needle bearing depth between face of cage needle bearing and hub assembly. See Fig. 6. Install NEW thrust washer. Ensure all 8 locking tabs are seated into groove in hub. Clean and inspect main steering knuckle seal. If seal is okay, go to step 5. If seal is worn or damaged, using a drift, remove seal from steering knuckle. Clean main seal bore. Using air pressure, flush vacuum hose and steering knuckle vacuum chambers. Inspect steering knuckle main seal bore for damage, nicks, burrs or pitting. Apply a thin coat of Ford High Temperature Wheel Bearing Grease (E8TZ-19590-A), or equivalent to bore of steering knuckle. Position main seal into Seal Depth Set/Vacuum Test Cap (205-400). Using Seal Replacer/CV Tester (205-399), install seal until it seats against steering knuckle. See Fig. 7. Apply at least 3 grams of Ford High Temperature Wheel Bearing Grease (E8TZ-19590-A) to sealing surface of main seal. Install NEW hub "O" ring. Apply Ford High Temperature Wheel Bearing Grease (E8TZ-19590-A) to hub bearing "O" ring. Position axle shaft and hub in steering knuckle. DO NOT damage hub "O" ring or main steering knuckle seal. Install 3 hub mounting bolts. Install tie rod end and nut. Install NEW cotter pin. Place NEW circlip with steel band facing outward onto Snap Ring Sleeve (205-403). Using Pusher (T81P-3504-M2) and Seal Remover Guide (T81P-3504-E), press retainer ring onto axle shaft while pulling on axle shaft. See Fig. 8. Listen for an audible click as circlip seats. To complete installation, reverse removal procedure. Reuse hub locks if not cracked or broken. Hub lock should be in engaged position while aligning to axle shaft and hub. It may be necessary to bounce axle shaft and turn wheel hub to align hub lock splines. Position hub lock onto hub using hand pressure. Using a rubber mallet, install hub lock. Ensure hub lock locking arms are fully seated in hub groove. Perform wheel end vacuum leak test. See WHEEL END VACUUM LEAK TEST under ADJUSTMENTS & INSPECTION. Tighten remaining bolts and nuts to specification. See TORQUE SPECIFICATIONS. Before driving vehicle, pump brake pedal several times to restore normal pedal position. Check wheel alignment. See appropriate SPECIFICATIONS & PROCEDURES article in WHEEL ALIGNMENT.
