Tools required

Parts

• Front sway bar link kit (left) × 1 — Use OEM specification or aftermarket equivalent
• Front sway bar link kit (right) × 1 — Use OEM specification or aftermarket equivalent

Preparation

1. Park vehicle on level, solid ground and set parking brake firmly
2. Chock rear wheels securely
3. If rusted, spray all sway bar link fasteners with penetrating oil and allow 15-30 minutes to soak
4. Raise front of vehicle with floor jack at frame rail
5. Support vehicle securely on jack stands placed under frame rails behind front axle
6. Allow suspension to hang freely with wheels off ground

Procedure

1. 1

   Locate sway bar links
   The front sway bar runs laterally across the frame, typically mounted to the frame rails. The sway bar links connect each end of the sway bar to the front suspension (Twin I-Beam on 2WD models). On 1972 F-100 models, these are typically bolt-style links with rubber bushings and metal sleeves stacked on a through-bolt. Verified detail (1972 F-100s with twin I-beam front suspension typically have the sway bar mounted to the I-beams or radius arms, not connecting directly to the front axle housing. The 1972 F-100 does not have a solid front axle; it uses twin I-beam independent front suspension.): The front sway bar runs laterally across the front of the vehicle. The sway bar links connect each end of the sway bar to the lower control arms or radius arms on the twin I-beam suspension.
2. 2

   Inspect link mounting configuration
   Identify whether your links use through-bolts with bushings or ball joint studs with castle nuts. The 1972 F-100 typically uses a bolt-through design with rubber bushings and metal sleeves. Note the orientation of washers and bushings for reassembly.
3. 3

   Remove upper link fastener
   Using a 9/16" wrench on the nut and another wrench or socket on the bolt head, remove the upper fastener connecting the link to the sway bar. If the bolt spins freely, hold the bolt head while turning the nut. The fastener passes through the sway bar eye and link with bushings on each side.
   ⚠If fasteners are severely corroded, use a wire brush to clean threads. Avoid using excessive force that could break the bolt, as this would require drilling out the fastener.
4. 4

   Remove lower link fastener
   Using a 9/16" wrench on the nut and another on the bolt head, remove the lower fastener connecting the link to the front suspension bracket or mounting point. Support the link as you remove the last fastener to prevent it from dropping. Verified detail (References the 'axle bracket' — the 2WD F-100 uses Twin I-Beam suspension, not a solid axle, so the mounting point is on the I-beam or lower arm bracket.): On some configurations, the lower mount may use a stud and nut rather than a through-bolt. If so, the stud is typically pressed into the suspension bracket and only the nut needs removal. Verified detail (Reference to 'front axle bracket' is inconsistent with the twin I-beam independent front suspension used on 1972 F-100s. The lower mount would connect to the radius arm or lower I-beam, not a solid axle bracket.): Using a 3/4" wrench on the nut and another on the bolt head, remove the lower fastener connecting the link to the radius arm or lower I-beam mounting point.
   ℹ️On some configurations, the lower mount may use a stud and nut rather than a through-bolt. If so, the stud is typically pressed into the axle bracket and only the nut needs removal.
5. 5

   Remove old sway bar link
   Pull the link assembly away from the mounting points. Remove and inspect all bushings, washers, and sleeves. Note the order and orientation of components for proper reassembly. Clean the mounting areas on both the sway bar and axle with a wire brush.
6. 6

   Prepare new link assembly
   Unpack the new sway bar link kit. Verify all components are included: link, upper and lower bushings (typically 4 total), metal sleeves, washers, and fasteners. Pre-assemble the bushings onto the link ends with sleeves inserted through the bushing centers. Apply a light coating of silicone grease to bushings to ease installation and reduce future squeaking.
7. 7

   Install new link to axle
   Position the lower end of the new link to the radius arm or lower I-beam mounting point. Insert the lower bolt through the bushing, link, and mounting bracket (or onto the stud if applicable). Install the washer and thread the nut on finger-tight. Do not fully tighten yet.
8. 8

   Connect link to sway bar
   Align the upper end of the link with the sway bar eye. You may need to use a pry bar to gently lever the sway bar into alignment with the link. Insert the upper bolt through the bushing, sway bar eye, link, and outer bushing. Install washer and thread nut finger-tight.
9. 9

   Tighten link fasteners
   With the suspension hanging at full droop, tighten the upper fastener until snug, then the lower fastener until snug. The bushings should be compressed but not crushed. Typical specification is to tighten until bushings just begin to bulge slightly, approximately 25-35 ft-lbs for these fasteners, but exact torque specifications are not documented. Final tightening should be done with the suspension at normal ride height if possible.
   ⚠Over-tightening will crush the rubber bushings prematurely and cause binding. Under-tightening will allow excessive movement and clunking. Bushings should be snug but not deformed.
10. 10

    Repeat for opposite side
    Repeat steps 3 through 9 for the sway bar link on the opposite side of the vehicle. Both links should be replaced as a pair to maintain consistent handling characteristics.
11. 11

    Lower vehicle and final torque check
    Remove jack stands and carefully lower the vehicle until the suspension is at normal ride height but the tires are just touching the ground. With the suspension loaded, perform a final check of all link fasteners (upper and lower on each side) to ensure they are properly tightened. Bounce the front end a few times to settle the suspension, then recheck fastener tightness.

Reassembly

1. Ensure all fasteners are tightened with suspension at or near normal ride height to prevent bushing bind
2. Verify sway bar moves freely through its range of motion without binding
3. Double-check that no tools or parts were left in the work area

Verification

• Test drive the vehicle and listen for any clunking or rattling from the front suspension over bumps
• Verify improved body roll control during cornering if replacing worn links
• After 50-100 miles, recheck all link fasteners for proper tightness
• Visually inspect links after test drive to ensure bushings are properly seated and fasteners remain tight
