2016 GMC Sierra 1500 Wheel Alignment Specifications

Quick reference

Note: Specific preferred values for caster vary depending on the vehicle's trim and suspension package. Always refer to a comprehensive alignment database for exact numbers.

Adjustability

The 2016 GMC Sierra 1500 offers some factory adjustability for its front-end alignment, but like most pickup trucks, the rear axle is generally non-adjustable. Understanding what can and cannot be adjusted on your Sierra is crucial for proper maintenance and avoiding unnecessary repairs.

Front Camber: On the 2016 GMC Sierra 1500, front camber is not factory adjustable without additional hardware. From the factory, camber angles are set by the non-adjustable lower control arm mounts. If your Sierra has an out-of-spec front camber reading, it usually indicates worn suspension components, damage, or requires aftermarket adjustment solutions. Aftermarket cam bolts or upper control arms with adjustable ball joint mounts can be installed to achieve camber adjustments.

Front Caster: Similar to camber, front caster on the 2016 GMC Sierra 1500 is not directly adjustable from the factory without aftermarket components. Caster is primarily determined by the positioning of the upper and lower control arms. Adjustments to caster typically involve the installation of aftermarket upper control arms designed with eccentric ball joint mounts or cam bolts for the lower control arms that allow for forward or rearward movement. Incorrect caster can lead to steering pull and affect steering returnability.

Front Total Toe: This is the most critical and factory-adjustable angle on your Sierra 1500. Front total toe is adjusted by turning the tie rod ends on each side of the steering linkage. This effectively lengthens or shortens the tie rods, pivoting the wheels inward or outward. Proper toe ensures the tires track straight, minimizes scrub, and prevents premature tire wear. Both individual toe (the angle of each front wheel relative to the vehicle centerline) and total toe (the sum of both individual toe angles) are adjusted simultaneously through the tie rod ends.

Rear Alignment: The rear axle of the 2016 GMC Sierra 1500, like most solid-axle pickup trucks, is non-adjustable from the factory. Rear camber, toe, and thrust angle are predetermined by the manufacturing of the axle housing and its mounting to the chassis with leaf springs. If you experience abnormal rear tire wear or a thrust angle issue (where the rear wheels are not tracking perfectly parallel with the front wheels or the centerline of the vehicle), it almost always indicates a bent axle housing, damaged leaf springs, worn spring bushings, or a shifted axle. These issues require component replacement or repair, not alignment adjustments.

Recommended adjustment hardware

Since front camber and caster are not factory adjustable on the 2016 GMC Sierra 1500, if these angles are out of specification due to wear, modifications (like a leveling kit), or damage, you will likely need aftermarket solutions. Common options include:

• SPC Cam Bolts or similar eccentric bolts: These replace the factory lower control arm bolts and allow for a limited range of camber and caster adjustment by shifting the position of the lower control arm. They are a popular choice for correcting alignment after installing leveling kits.
• Aftermarket Upper Control Arms (UCAs): Many manufacturers offer UCAs with built-in adjustability, often through eccentric ball joint mounts. These are particularly useful for lifted trucks where the factory UCAs may limit articulation and alignment potential.

Symptoms of bad alignment

Recognizing the signs of a misaligned vehicle can save you money on tires and improve driving safety. Here are common symptoms:

• Uneven Tire Wear: This is the most common and telling sign. Look for:
  • Feathering: Tires have a saw-tooth or feathered edge when you run your hand across the tread, indicating excessive toe.
  • Inner or Outer Shoulder Wear: One edge of the tire wears down much faster than the rest, often a sign of incorrect camber.
  • Cupping/Scalloping: Irregular dips or scoops out of the tread, often linked to worn suspension components or an imbalance, but can also be exacerbated by alignment issues.
• Vehicle Pulling: Your Sierra consistently drifts to one side of the road, requiring you to constantly correct the steering. This can be caused by incorrect caster or camber between the front wheels.
• Steering Wheel Not Centered: Even when driving straight, your steering wheel is turned to one side. This can indicate an incorrect toe setting.
• Loose or Wandering Steering: The vehicle feels difficult to keep in a straight line, requiring constant small corrections. This can be a sign of incorrect caster or worn steering/suspension components.
• Squealing Tires: Tires squeal during turns, even at low speeds, which can indicate excessive toe settings.

When to align

To maintain optimal handling and tire life, consider an alignment in these situations:

• After installing new tires: New tires need a proper alignment to ensure even wear from the start.
• After any suspension or steering component replacement: This includes tie rods, ball joints, control arms, shocks, struts, or any component that affects wheel angles.
• After hitting a pothole, curb, or having an accident: Even a minor impact can knock your alignment out of spec.
• If you notice any of the "Symptoms of bad alignment" listed above.
• Every 1-2 years or every 15,000-30,000 miles as preventative maintenance, even if you don't notice any issues. Components wear over time.

Typical alignment cost

The cost of a wheel alignment for a 2016 GMC Sierra 1500 can vary depending on your location, the shop, and whether any additional parts or labor are required (e.g., if cam bolts need to be installed). Generally, you can expect to pay anywhere from $90 to $180 for a standard two-wheel (front axle) or four-wheel alignment (which on your Sierra primarily focuses on ensuring the front axle is aligned to the non-adjustable rear axle). If aftermarket adjustment hardware needs to be installed, the cost will be higher due to parts and additional labor.
