Safety precautions
- Work on a level surface or alignment rack. Chock rear wheels and set parking brake. Put transmission in park/neutral as required by manual.
- If lifting, use rated jacks and stands or an alignment lift. Never rely only on hydraulic jacks.
- Wear eye protection and gloves. Keep hands clear while moving steering.
- Do not attempt alignment when steering/suspension components are loose or damaged — replace parts first.
- Use specified torque values for fasteners.

Step-by-step alignment procedure (typical heavy-truck/single front-axle method)

1. Preparation & initial inspection
- Verify vehicle unloaded or loaded to specified ride height for alignment (check manual).
- Check tire pressures and wear; correct to specification. Rotate/replace tires if damaged.
- Inspect steering & suspension: ball joints/kingpins, tie-rod ends, drag link, pitman/idler arms, bushings, leaf springs/shocks, wheel bearings. Replace any worn or loose components before aligning. Common rule: if you can rock a tie-rod end by hand or see play in steering, replace it.
- Check wheel bearings and torque wheel nuts to spec.
- Ensure steering stops, steering wheel alignment (mark center) and bump stops are intact.

2. Mount alignment equipment / set up centerline
- On a computerized rack: clamp sensors to each wheel per manufacturer instructions and input wheel/tire sizes.
- On manual set-up: place turnplates under front wheels (free-turning). Set rear wheels on level surface. Measure and mark the vehicle centerline — use stringline method: run two strings parallel to the vehicle long axis, equal distance from the body/axle, and check distances to same reference points on each axle; adjust until centered.
- Alternatively use chassis centerline by measuring equal distances to frame rails or axle faces.

How the tools are used
- Turnplates: allow front wheels to pivot freely so caster adjustments and accurate toe readings are possible.
- Toe plates / stringline: use plates or precision tape measures at hub centerline to measure front-to-back distances between left and right wheels to determine toe.
- Camber/caster gauge: attach to wheel hub or rotor face; for caster most gauges use change-in-camber while turning the wheel through specified degrees or an inclinometer that measures spindle angle relative to vertical.
- Computer heads: measure actual camber/caster/toe electronically; follow unit prompts for ride height and vehicle parameters.

3. Measure and record baseline settings
- Measure and log toe (each side), total toe, camber left/right, caster left/right, and thrust angle (rear axle center relative to front centerline). Note steering wheel off-center.
- If measurements are within spec, only minor adjustments may be needed. If out-of-spec by a lot, find worn components.

4. Center the steering wheel
- Lock front wheels straight using the steering column/steering wheel centering tool or mark wheel center. Count steering wheel turns from lock-to-lock to find exact midpoint if needed.
- Adjust drag link/pitman arm orientation only after toe/caster/camber set so steering wheel centering remains accurate.

5. Adjust toe
- For most trucks the primary adjustment is toe via the tie-rod(s).
- Loosen tie-rod locknuts. Turn either tie-rod to lengthen/shorten and achieve the specified toe per side or total toe. Use toe plates or alignment heads to read values while adjusting.
- Procedure: Turn steering wheel to drop slack, then center and adjust tie-rods equally to keep steering centered as much as possible. Recheck steering wheel center after toe set; small additional adjustments to drag link/pitman arm may be required.
- Tighten tie-rod locknuts to spec and torque.

6. Adjust camber & caster (as applicable)
- Some truck front axles are solid and camber/caster are set by axle seating, shims, or kingpin/ball joint adjustments.
- If adjustable: use camber/caster gauge and adjust eccentric bolts, shims at axle seat, or shim/remove bolts to bring camber and caster within spec. Caster is often checked by turning the wheel to each specified angle and using a caster gauge or the change-in-camber method.
- If not adjustable and out of spec, inspect for bent axle or worn kingpins/ball joints and replace or re-bush as necessary. Replacing kingpin bushings or re-machining axle is required when angles are incorrect due to wear/damage.

7. Set thrust angle / rear alignment relation
- Thrust angle: ensure rear axle centerline is parallel to vehicle centerline. If thrust angle is off, adjust rear axle alignment by adjusting leaf spring eye position, axle seat shims, or U-bolt positioning per manual. Some rear axles may use staggered shims.
- Thrust off can cause the truck to drive crooked even with front wheels aligned.

8. Steering wheel centering final
- With toe set and steering wheel centered, re-check caster/camber and toe. Make fine tie-rod and drag link/pitman arm adjustments as needed to keep steering wheel straight.
- Tighten all locknuts and torque to spec.

9. Final checks and road test
- Torque wheels to spec, lower vehicle if raised.
- Test drive at low speeds checking straight-line tracking, steering response, and return-to-center. Check for vibration or pulling.
- Re-inspect and re-measure alignment values after road test; small tweaks as required.

Replacement parts and when required
- Tie-rod ends (inner/outer): Replace when play exists. Tie-rod replacement is the most common alignment-related repair.
- Drag link, pitman arm, idler arm: Replace if worn or if the steering wheel cannot be centered after tie-rod adjustment.
- Kingpins/ball joints and bushings: Replace if there is vertical or lateral play; worn kingpins will cause repeat alignment drift and uneven tire wear.
- Shims or axle-seat components: Replace or add shims when camber/caster/axle centering require correction and the axle seating allows shim adjustment.
- Wheel bearings/wheels: Replace if worn or runout present.

Common pitfalls & mistakes to avoid
- Trying to align with worn steering/suspension parts — the alignment won’t hold.
- Incorrect tire pressures or mismatched tires — affects measurements.
- Not setting vehicle to correct ride height or loading condition as specified by the manual.
- Not centering steering wheel before measuring and making asymmetric tie-rod adjustments.
- Over-tightening tie-rod locknuts before confirming final toe — can change settings.
- Forgetting to torque at final values after adjustments.
- Assuming camber/caster are adjustable when axle requires shims or reconditioning — forcing adjustments can damage parts.
- Using only a test drive without re-checking measurements afterward.
- Ignoring thrust angle/rear axle alignment — correct front alignment won’t fix crooked tracking if rear is wrong.

Quick usage tips for specific tools
- Toe plates: place at hub height parallel to wheel. Measure distance between plates at the front and rear of rims; difference divided by wheelbase gives toe angle in degrees or directly as mm/inches.
- Stringline: set two strings parallel to the vehicle centerline and measure perpendicular distance from string to wheel rim at front and rear for toe/camber checks.
- Camber/caster gauge: zero gauge on a reference surface. Clamp to hub/rotor face. For caster, turn wheel to the specified angles and read change or use inclinometer readings per gauge instructions.
- Alignment computer: follow calibrations & input accurate wheel/tire sizes. Make sure sensors are clean and clamps tight; loose clamps give false readings.

Final note
- Always refer to the Ford Trader T3000/T3500/T4000 service manual for specific alignment specifications (toe, camber, caster, thrust angle), torque values, and any model-year differences. Replace any worn parts before attempting final alignment to ensure results hold.
