2019 GMC Acadia Wheel Alignment Specifications

Quick reference

These specifications are for a 2019 GMC Acadia and are intended for reference by professional alignment technicians. Values are shown in degrees.

Adjustability

Understanding which alignment angles are adjustable from the factory is crucial for an efficient and accurate alignment process on the 2019 GMC Acadia.

Front Axle:

• Camber/Caster: The front suspension does not have a dedicated factory adjustment for camber or caster. The strut-to-knuckle mounting holes are not slotted. If camber or caster are out of specification, it typically indicates that a component has been bent or damaged. To correct for minor deviations, technicians often loosen the subframe bolts and shift the entire subframe slightly. For larger corrections, aftermarket cam bolts are required.
• Toe: Front toe is the primary and most easily adjustable angle. It is adjusted by loosening the jam nuts on the outer tie rod ends and rotating the inner tie rod.

Rear Axle:

• Camber: The rear camber is not factory adjustable. Similar to the front, any significant deviation from the preferred value suggests worn or damaged components.
• Toe: Rear toe is adjustable. The adjustment is made via an eccentric cam bolt on the inboard mounting point of the rear lower control arm.

Recommended adjustment hardware

When factory adjustments are not sufficient to bring the 2019 Acadia into alignment, aftermarket kits provide a solution.

• Front Camber/Caster: For vehicles requiring front-end camber or caster correction, a popular solution is the SPC (Specialty Products Company) part #86252. This is an eccentric cam bolt kit designed for the strut-to-knuckle interface. Installing one of these kits per side allows for up to ±1.75° of camber and caster change, which is typically more than enough to correct for subframe sag or minor collision damage.

Symptoms of bad alignment

A vehicle with improper alignment will exhibit several distinct symptoms, many of which are evident in the tires.

• Vehicle Pulling or Drifting: One of the most common complaints is the vehicle pulling to the left or right when driving on a straight, flat road. This is often caused by an uneven side-to-side camber or caster.
• Off-Center Steering Wheel: The steering wheel is not level when driving straight. This is a direct result of incorrect total toe, often after a toe adjustment was performed without centering the steering wheel first.
• Tire Wear Patterns:
  • Feathering/Scalloping: Saw-toothed or feathered edges on the tread blocks are a classic sign of a toe problem. The tire is essentially being dragged sideways as it rolls forward.
  • Inner/Outer Edge Wear: This points directly to a camber issue. If the top of the tire is tilted inward (negative camber), the inner edge of the tire will wear down. If it's tilted outward (positive camber), the outer edge will wear.
  • Cupping: This pattern of uneven, sporadic dips in the tread is often caused by worn shocks or struts but is exacerbated by poor alignment.

When to align

It is a common misconception that wheel alignments are only needed when there's a problem. Regular alignment checks are key to maximizing tire life and ensuring vehicle safety. An alignment is recommended:

• After installing new tires: To protect your investment and ensure they wear evenly from the start.
• After any suspension or steering component replacement: This includes struts, control arms, tie rods, and ball joints. Replacing these parts will almost always alter the alignment angles.
• After a significant impact: Hitting a large pothole, a curb, or being in a minor accident can easily knock the suspension out of alignment.
• Every 12 months or 12,000 miles: As a part of routine preventative maintenance to catch any issues before they cause significant tire wear.

Typical alignment cost

The cost for a four-wheel alignment on a 2019 GMC Acadia typically ranges from $120 to $250. The price can vary based on the shop's location, labor rates, and whether any additional parts or labor are required to correct severe alignment issues (such as installing cam bolts).
