Preparation
- Park vehicle on level surface and engage parking brake
- Turn steering wheel to center position and lock with steering wheel holder or seatbelt
- Raise front of vehicle and support securely on jack stands at frame rail locations
- Remove both front wheels
- Spray penetrating oil on tie rod end castle nuts and allow to soak 10-15 minutes
- Place drain pan under steering rack area
Procedure
- 1Remove front skid plate if equippedRemove the mounting bolts securing the front skid plate using appropriate socket. Set skid plate aside. This provides access to the steering rack and tie rod ends.Torque specMounting Bolts34 Nm (25 lb-ft)
- 2Remove tie rod end cotter pinsLocate the castle nuts on both outer tie rod ends where they connect to the steering knuckles. Use pliers to straighten and remove the cotter pins from both sides. Discard old cotter pins.
- 3Loosen tie rod end castle nutsUsing appropriate socket, loosen but do not fully remove the tie rod end castle nuts on both sides. Leave nuts threaded on 2-3 turns to protect threads and prevent sudden separation.Torque specTie Rod End Castle Nut55 Nm (41 lb-ft)
- 4Separate tie rod ends from knucklesUse tie rod end separator or pickle fork to break the taper connection between the tie rod ends and steering knuckles on both sides. Once separated, remove the castle nuts completely. Support the tie rod ends to prevent damage to boots during removal.
- 5Mark and remove inner tie rods if necessaryIf replacing inner boots or if access requires, mark the position of the tie rod jam nut and inner tie rod connection with paint or marker to preserve alignment. Loosen jam nut and count turns as you unthread the outer tie rod from the inner tie rod assembly. Record turns for reassembly.Torque specTie Rod Nut68 Nm (50 lb-ft)
- 6Remove old boot clampsLocate the boot clamps on the damaged or worn rack boot. Use clamp pliers or side cutters to cut and remove the clamps from both the rack housing end and the tie rod end of the boot. Remove clamps from both sides being serviced.
- 7Remove old bootsSlide the old boots off the rack assembly. Note the orientation and positioning of the boots. Clean the rack housing and tie rod mounting surfaces with wire brush, removing any old grease, dirt, or corrosion. Inspect rack for damage or excessive wear.ℹ️If rack shows signs of fluid leakage or damage beyond boot wear, rack replacement may be necessary
- 8Install new bootsApply a light coating of grease to the rack shaft if specified in boot kit instructions. Slide the new boots onto the rack assembly, ensuring proper orientation with smaller end toward tie rod and larger end toward rack housing. Position boots in correct location on both sides.
- 9Install new boot clampsPosition new clamps (typically included in boot kit) on both ends of each boot. Use boot clamp pliers to crimp clamps securely, ensuring boots are sealed against rack housing and tie rod connection points. Verify clamps are tight and boots cannot rotate or slide.
- 10Reinstall inner tie rods if removedIf tie rods were removed, thread the outer tie rod back onto the inner tie rod the same number of turns recorded during removal, aligning with reference marks. This preserves approximate alignment. Do not fully tighten jam nut yet.
- 11Reconnect tie rod ends to knucklesInsert tie rod end studs into the steering knuckle tapers on both sides. Install castle nuts and tighten to specification. Ensure cotter pin holes align; tighten slightly additional if needed to align holes, but do not back off torque. Install new cotter pins and bend to secure.Torque specTie Rod End Castle Nut55 Nm (41 lb-ft)
- 12Tighten tie rod jam nutsHold the inner tie rod with appropriate wrench to prevent rotation. Torque the tie rod jam nuts to specification on both sides to lock the tie rod adjustment in place.Torque specTie Rod Nut68 Nm (50 lb-ft)
- 13Check power steering fluid levelCheck power steering fluid reservoir level. Top off with Motorcraft MERCON LV as needed to bring to proper level. Start engine and turn steering wheel lock-to-lock several times to purge air from system. Recheck fluid level and top off if necessary.⚠Check for leaks around boots and connections while turning steering wheel
- 14Reinstall wheels and skid plateReinstall both front wheels and hand-tighten lug nuts in star pattern. If skid plate was removed, reinstall with mounting bolts torqued to specification. Lower vehicle to ground and torque wheel lug nuts to specification in star pattern.Torque specMounting Bolts34 Nm (25 lb-ft)Wheel Lug Nuts169 Nm (125 lb-ft)
Reassembly
- Ensure all boot clamps are properly crimped and secure
- Verify all fasteners are torqued to specification
- Confirm tie rod ends are properly seated in knuckle tapers with new cotter pins installed
- Check power steering fluid level is correct and no leaks are present
Verification
- Start engine and turn steering wheel fully left and right several times, listening for unusual noises
- Check for power steering fluid leaks around boots, connections, and rack housing
- Verify steering returns to center smoothly with no binding
- Test drive vehicle at low speed in safe area to confirm steering operates normally
- Schedule front end alignment as tie rod adjustment may have shifted slightly during service
