Preparation

1. Verify alignment specifications for the specific model year and wheel size from Ford service manual
2. Inspect all suspension components for excessive wear including ball joints, tie rod ends, control arm bushings, and steering linkage
3. Check for bent or damaged suspension or frame components that would prevent proper alignment
4. Set all tire pressures to manufacturer specification (typically 35 PSI front/rear for this vehicle)
5. Ensure vehicle is at curb weight with driver's seat weighted to 150 lbs and fuel tank at least half full
6. Bounce each corner of the vehicle several times to settle suspension before starting alignment
7. Position vehicle on alignment rack with wheels straight ahead on turntables and slip plates

Procedure

1. 1

   Mount alignment equipment and perform initial readings
   Attach alignment targets or sensors to all four wheels according to alignment machine manufacturer instructions. Perform wheel runout compensation procedure if required by your alignment system. Lock the steering wheel in straight-ahead position using steering wheel lock or brake pedal depressor. Raise and lower vehicle on alignment rack to ensure turntables and slip plates move freely. Take initial alignment readings for all four wheels and record toe, camber, and caster values.
2. 2

   Verify rear axle alignment
   Check rear axle thrust angle reading on alignment machine. For this solid rear axle vehicle, thrust angle should be within ±0.10 degrees. If thrust angle is out of specification, inspect rear axle mounting and leaf spring bushings for damage or shifting. Rear toe is not adjustable on this vehicle; if rear toe is out of specification, inspect for bent axle housing or damaged suspension components. Note the thrust angle value to use as reference for front toe adjustment.
3. 3

   Adjust front camber (if necessary)
   Locate the upper control arm cam bolts at the frame mounting point. Camber is adjusted by rotating the eccentric cam washers on the upper control arm pivot bolts. Apply penetrating lubricant to cam bolt threads if corroded. Loosen both upper control arm cam bolts slightly (do not remove completely). Rotate the cam bolts to adjust camber to factory specification, typically -0.5 to +1.0 degrees. The front cam primarily adjusts camber while the rear cam affects both camber and caster. Make small adjustments and recheck readings on alignment machine. Once camber is within specification, proceed to caster adjustment before final tightening.

   Adjust front caster
   Caster is adjusted using the same upper control arm cam bolts. To increase caster, rotate the front cam bolt to move the upper ball joint rearward, or rotate the rear cam bolt to move the mounting point forward. To decrease caster, do the opposite. Factory specification is typically +3.0 to +5.0 degrees. Adjust both sides equally to maintain cross-caster within ±0.5 degrees. Caster adjustments will affect camber readings, so recheck camber after adjusting caster and fine-tune both settings as needed. Once both camber and caster are within specification on both sides, torque cam bolts to specification.

   Verify cam bolt torque
   With camber and caster adjustments complete, verify both upper control arm cam bolts are torqued to 155.0 Nm (114.0 lb-ft) on each side. Use a torque wrench and 21mm socket. Tighten in a cross pattern (front bolt then rear bolt) to prevent shifting. After torquing, lower vehicle momentarily to load suspension, then raise and recheck camber and caster readings to ensure settings did not shift during final tightening. If readings changed, repeat adjustment process.
   ⚠Cam bolts are critical fasteners; under-torquing can allow suspension geometry to shift under load causing unsafe handling

   Unlock steering and verify steering wheel position
   Remove steering wheel lock or brake pedal depressor. Verify steering wheel is centered with wheels pointed straight ahead. If steering wheel is off-center, this will be corrected during toe adjustment by adjusting left and right tie rods unequally. Note the steering wheel position before proceeding.
7. 7

   Adjust front toe
   Front toe is adjusted at the outer tie rod ends. Loosen the jam nut on each outer tie rod end using an 18mm wrench. The jam nut is located between the tie rod end and the adjusting sleeve. Use tie rod adjusting tool or large adjustable wrench to rotate the tie rod sleeve, which will lengthen or shorten the tie rod. To increase toe-in (reduce positive toe), lengthen both tie rods equally. To decrease toe-in (increase positive toe), shorten both tie rods. Factory specification is typically +0.10 to +0.30 degrees total toe. If steering wheel was off-center, adjust one side more than the other to center the wheel while achieving proper total toe. Make small adjustments (1/4 turn at a time) and recheck alignment readings.

   Torque tie rod jam nuts and verify toe settings
   Once front toe is within specification and steering wheel is centered, hold the tie rod sleeve stationary and torque both tie rod jam nuts to 55.0 Nm (41.0 lb-ft). Ensure the tie rod sleeve does not rotate during final tightening. After torquing jam nuts, lower vehicle momentarily to load suspension, raise again, and perform final alignment measurement to verify toe settings did not shift. Check that steering wheel is still centered.
   ⚠Hold tie rod sleeve firmly while torquing jam nut to prevent rotation; any movement will change toe setting

   Perform final alignment verification
   Remove alignment targets or sensors from all wheels. Perform final alignment reading sweep to verify all specifications are within factory tolerances. Print alignment report showing before and after measurements. Verify the following are within specification: front and rear camber, front caster and cross-caster, front and rear toe (individual and total), and rear thrust angle. Confirm steering wheel is centered with wheels straight ahead.
10. 10

    Road test vehicle
    Lower vehicle from alignment rack. Road test vehicle at speeds up to 45 mph on a level, straight road. Verify steering wheel remains centered during straight-line driving. Check for proper steering return after turns. Test for even tire contact and absence of pulling or drifting. Listen for any new suspension noises that might indicate loose components. If any issues are found, return to alignment rack and recheck all measurements and torque specifications.

Reassembly

1. Ensure all cam bolts and tie rod jam nuts are torqued to specification
2. Verify no tools or equipment were left in wheel wells or suspension areas
3. Remove alignment equipment and steering wheel lock
4. Clean any penetrating lubricant or grease from suspension components

Verification

• Print and review final alignment report showing all measurements within factory specification
• Verify steering wheel is centered with wheels pointed straight ahead
• Confirm vehicle drives straight without pulling or drifting on level road
• Check that steering returns to center properly after turns
• Verify no unusual tire wear patterns develop over next 500-1000 miles
• Recheck alignment after 30 days or if vehicle experiences suspension impact
