Tools required

Parts

• Outer tie rod end (driver side) × 1 — Use OEM specification
• Outer tie rod end (passenger side) × 1 — Use OEM specification
• Inner tie rod end (driver side) × 1 — Use OEM specification
• Inner tie rod end (passenger side) × 1 — Use OEM specification

Preparation

1. Park vehicle on level, solid surface and engage parking brake.
2. Place wheel chocks behind rear wheels.
3. Loosen front wheel lug nuts while vehicle is on ground (do not remove).
4. Apply penetrating oil to all tie rod end castle nuts, tie rod adjuster sleeve clamp bolts, and inner tie rod threads. Allow 15 minutes to penetrate.
5. Mark the front wheels to indicate straight-ahead steering position.

Procedure

1. 1

   Lift and secure the vehicle
   Lift the front of the vehicle with a floor jack at the front crossmember. Raise to working height and position jack stands under the frame rails behind the front wheels. Lower vehicle onto jack stands and verify stability. Remove both front wheels completely.
2. 2

   Mark tie rod length reference - driver side
   Turn steering wheel to center the wheels in straight-ahead position. Locate the outer tie rod end adjuster sleeve (the threaded tube connecting inner and outer tie rod ends). Use white paint marker to draw a line across the outer tie rod threads and the adjuster sleeve, creating an alignment reference. Count and record the number of threads visible between the adjuster sleeve and the outer tie rod jam nut. Measure and record the total exposed thread length from the end of the adjuster sleeve to the tie rod end stud.
3. 3

   Remove outer tie rod end - driver side
   Straighten and remove the cotter pin from the outer tie rod end castle nut at the steering knuckle. Remove the castle nut completely. Position the tie rod end separator tool between the steering knuckle and the tie rod end. Strike the separator tool with a hammer using firm, controlled blows until the tie rod end tapers separates from the knuckle. Loosen the adjuster sleeve clamp bolt(s). Unthread the outer tie rod end from the adjuster sleeve while counting complete rotations. Record the rotation count for reassembly reference.
4. 4

   Remove inner tie rod end - driver side
   Locate the inner tie rod end connection at the steering center link (relay rod). Straighten and remove the cotter pin from the inner tie rod castle nut. Remove the castle nut. Use the tie rod separator tool to separate the inner tie rod taper from the center link, striking the tool with controlled hammer blows until the tapered stud releases from the center link.ve still attached) from the drag link. Verified detail (The 1972 F-100 steering linkage has tie rods that connect between the center link and the steering knuckles. The tie rods do not thread into the center link; they use tapered studs with castle nuts at both ends (center link end and knuckle end). The adjustable sleeve is in the middle of the tie rod.): Locate the tie rod connection at the center link (the end closest to the center of the vehicle). Straighten and remove the cotter pin from the tie rod castle nut at the center link. Remove the castle nut. Use the tie rod separator tool to separate the tie rod taper from the center link, striking the tool with controlled hammer blows. The tie rod assembly is now free from the vehicle.
5. 5

   Disassemble and inspect driver side components
   With the complete tie rod assembly removed, fully separate the adjuster sleeve from the inner tie rod end by unthreading it. Inspect all threads on the old inner and outer tie rod ends for damage. Inspect the adjuster sleeve for cracks or damaged threads. If the sleeve is damaged, it should be replaced. Clean threads with a wire brush.
6. 6

   Assemble new driver side tie rod
   Thread the adjuster sleeve onto the new inner tie rod end approximately to the midpoint of available threads. Loosely tighten the adjuster sleeve clamp bolt(s) finger-tight only. Thread the new outer tie rod end into the adjuster sleeve using the same number of rotations recorded during disassembly. Align the paint marks as closely as possible to maintain approximate original length.
7. 7

   Install driver side tie rod assembly
   Install the tie rod end into the center link taper. Thread the castle nut onto the tie rod stud and tighten to 50 ft-lbs. Continue tightening as needed to align the castle nut slots with the cotter pin hole (do not loosen to align). Install a new cotter pin and bend the ends to secure. Insert the tie rod end into the steering knuckle taper. Thread the castle nut onto the tie rod stud and tighten to 50 ft-lbs. Continue tightening as needed to align castle nut slots with cotter pin hole. Install new cotter pin and secure.uter tie rod stud and tighten to 50 ft-lbs. Continue tightening as needed to align castle nut slots with cotter pin hole. Install new cotter pin and secure. Verified detail (Torque value is an AI best-guess placeholder and should be verified against the 1972 F-100 factory shop manual for the outer tie rod-to-knuckle castle nut.): Insert the outer tie rod end into the steering knuckle taper. Thread the castle nut onto the outer tie rod stud and tighten to the factory-specified torque (verify in 1972 F-100 shop manual; typically 35-50 ft-lbs). Continue tightening as needed to align castle nut slots with cotter pin hole. Install new cotter pin and secure. Verified detail (Ford light-truck tie rod end castle nuts of this era are typically torqued to roughly 35-50 ft-lbs at the outer knuckle but inner-to-center-link connections can differ. More importantly the taper connects to the center link, not a 'drag link.' Torque value flagged for verification against factory shop manual.): Install the inner tie rod end into the steering center link taper. Thread the castle nut onto the inner tie rod stud and tighten to the factory-specified torque (verify in 1972 F-100 shop manual; typically 35-50 ft-lbs).
8. 8

   Mark tie rod length reference - passenger side
   Repeat the marking procedure from Step 2 for the passenger side tie rod assembly. Mark alignment reference across outer tie rod threads and adjuster sleeve. Count and record visible threads and measure exposed thread length.
9. 9

   Remove outer tie rod end - passenger side
   Remove cotter pin and castle nut from the passenger side outer tie rod end at the steering knuckle. Separate the tie rod end taper using the separator tool and hammer. Loosen the adjuster sleeve clamp bolt(s). Unthread the outer tie rod end from the adjuster sleeve, counting and recording the rotations.
10. 10

    Remove inner tie rod end - passenger side
    Remove cotter pin and castle nut from the passenger side inner tie rod end at the drag link. Use the separator tool to separate the taper from the drag link. Unthread the complete tie rod assembly from the drag link.
11. 11

    Assemble and install passenger side tie rod
    Separate the adjuster sleeve from the old tie rod ends. Thread the adjuster sleeve onto the new tie rod end (center link end) to approximately midpoint. Thread the new tie rod end (knuckle end) into the adjuster sleeve using the recorded rotation count and alignment marks. Install the tie rod end into the center link taper and tighten castle nut to 50 ft-lbs, aligning slots for cotter pin. Install new cotter pin. Install the tie rod end into the steering knuckle taper and tighten castle nut to 50 ft-lbs, aligning slots for cotter pin. Install new cotter pin.. Install the outer tie rod end into the steering knuckle taper and tighten castle nut to 50 ft-lbs, aligning slots for cotter pin. Install new cotter pin.
12. 12

    Final adjustment and clamp torque
    Verify both tie rod assemblies are approximately equal length by comparing measurements. Adjust if necessary by loosening adjuster sleeve clamp bolts and threading tie rod ends in or out equally. Tighten all adjuster sleeve clamp bolts to the factory-specified torque (verify in 1972 F-100 shop manual; typically 13-20 ft-lbs). Verify all castle nuts are properly torqued and all cotter pins are installed and bent.

Reassembly

1. Reinstall both front wheels and hand-tighten lug nuts.
2. Raise vehicle off jack stands with floor jack, remove stands, and lower vehicle to ground.
3. Torque wheel lug nuts to 100 ft-lbs in a star pattern.
4. Test steering operation by turning wheel lock-to-lock while stationary to verify no binding or interference.

Verification

• Start engine and verify power steering operation with no unusual noises or binding through full steering range.
• Check that all cotter pins are properly installed and bent on all four tie rod end castle nuts.
• Verify steering wheel returns to approximate center position when released after turning.
• Schedule immediate professional wheel alignment to set toe, camber, and caster to factory specifications.
