2021 Ford F-150 Wheel Alignment Specifications

Quick reference

Adjustability

The 2021 Ford F-150 offers some factory adjustability for alignment angles, though certain corrections may require aftermarket components.

Front Axle:

• Camber: Factory non-adjustable. Camber on the 2021 F-150 is set by the vehicle's suspension geometry. If camber is out of specification, it often points to worn components (like ball joints or control arm bushings) or damage. To adjust camber, aftermarket adjustable cam bolts or control arms are typically required.
• Caster: Factory non-adjustable. Similar to camber, caster is largely determined by suspension design. Aftermarket eccentric bushings or adjustable control arms are needed for significant caster adjustments.
• Toe: Factory adjustable. The front toe on the F-150 can be adjusted using the tie rod ends. This allows for precise setting of individual and total toe to ensure the wheels are pointing straight ahead and rolling efficiently.

Rear Axle:

• Camber: Factory non-adjustable. The solid rear axle design of the F-150 means rear camber is not adjustable from the factory. If rear camber is found to be out, it often indicates a bent axle housing or other damage.
• Toe: Factory non-adjustable. Like rear camber, rear toe is not adjustable on the 2021 F-150 due to its solid axle design. Issues with rear toe usually suggest damage to the axle housing or mounting points.
• Thrust Angle: While not directly adjustable, thrust angle is a result of the alignment relationship between the front and rear axles. On an F-150, an incorrect thrust angle typically indicates a misaligned rear axle, which could be due to loose U-bolts, damaged spring perches, or a bent axle.

Recommended adjustment hardware

Given the non-adjustable nature of front camber and caster on the 2021 Ford F-150, if adjustments are needed beyond what worn parts replacement can correct, specific aftermarket hardware is recommended:

• Front Camber/Caster Correction: SPC Performance adjustable cam bolts (e.g., part number 25470) are a popular and effective solution for correcting front camber and caster. These bolts replace the original lower control arm bolts and allow for eccentric adjustment. Some aftermarket upper control arms also offer built-in adjustability for camber and caster.

Symptoms of bad alignment

An improperly aligned vehicle can manifest several symptoms, significantly impacting safety, tire life, and fuel economy. Here are common signs and associated tire wear patterns:

• Uneven Tire Wear: This is the most common and telling symptom.
  • Feathering: A sawtooth-like wear pattern across the tread, where one side of a tread block is higher than the other. Often indicates excessive toe-in or toe-out.
  • Camber Wear (Inner or Outer Edge): Wear concentrated on either the inside or outside edge of the tire. Inner edge wear suggests excessive negative camber, while outer edge wear suggests excessive positive camber.
  • Cupping/Scalloping: Pothole-like dips or scoops around the tread. While often linked to worn suspension components like shocks, severe alignment issues can contribute.
• Vehicle Pulling or Drifting: The vehicle consistently pulls to one side when driving on a flat road, requiring constant steering correction to stay straight. This is a classic sign of incorrect caster or camber, or a significant toe difference between the front wheels.
• Off-Center Steering Wheel: Even when driving straight, the steering wheel is not centered. This typically points to an issue with total toe or a misaligned steering wheel after a previous alignment.
• Loose or Wandering Steering: The vehicle feels unstable and difficult to keep in a straight line, often requiring numerous small steering corrections. Can be caused by insufficient positive caster.
• Squealing Tires: Tires that squeal, especially during turns, can indicate excessive toe or camber issues, causing the tires to drag or scrub across the road surface.

When to align

For your 2021 Ford F-150, regular alignment checks are crucial to maintain performance and tire longevity. Consider an alignment in these situations:

• After Suspension or Steering Component Replacement: Any time components like tie rods, ball joints, control arms, shocks/struts, or steering racks are replaced, an alignment is mandatory.
• After Installing New Tires: To maximize the life of your new tires and ensure optimal handling, an alignment should always be performed.
• After Hitting a Significant Pothole or Curb: Impacts with road hazards can easily knock your alignment out of specification.
• Annually or Every 12,000-15,000 Miles: Even without obvious symptoms, alignment angles can drift over time due to normal wear and tear.
• If You Notice Any Alignment Symptoms: Don't wait for extreme tire wear; address any pulling, uneven wear, or steering issues promptly.

Typical alignment cost

The cost of a wheel alignment for a 2021 Ford F-150 can vary based on location, the shop, and whether any adjustments or parts are needed. Generally, a two-wheel alignment (front only) might range from $75 to $120. A four-wheel alignment, which is recommended to also check the rear thrust angle, typically costs $100 to $180. If aftermarket adjustment components need to be installed, or if damaged suspension components require replacement first, the total cost will be higher.
