2015 Ram 3500 Wheel Alignment Specifications

Quick reference

Adjustability

The 2015 Ram 3500, like many heavy-duty trucks, has varying levels of adjustability for its alignment angles.

Front Axle:

• Camber and Caster: From the factory, the 2015 Ram 3500 does not offer direct factory adjustments for front camber and caster. These angles are set by the vehicle's suspension components. If camber or caster falls outside of the acceptable range, it often indicates worn suspension components (ball joints, control arm bushings) or a bent component. Aftermarket solutions, such as eccentric control arm bushings or adjustable ball joints (e.g., SPC Performance), are available to provide adjustment for these crucial angles.
• Total Toe & Individual Toe: The front total toe and individual toe are fully adjustable from the factory. This is typically done by adjusting the tie rod ends on the steering linkage.
• SAI (Steering Axis Inclination): SAI is a non-adjustable "set" angle determined by the design and mounting points of the steering knuckle and suspension. It is only affected by bent components.

Rear Axle:

• Camber: Rear camber on the 2015 Ram 3500 is generally non-adjustable from the factory. It's determined by the solid axle housing. If rear camber is outside of specification, it usually points to a bent axle housing or damaged suspension components.
• Total Toe & Individual Toe: Similar to camber, rear toe on a solid axle truck like the Ram 3500 is typically non-adjustable. A bent axle housing or improperly installed components would be the most common reasons for out-of-spec rear toe.
• Thrust Angle: Thrust angle is indirectly adjustable through the alignment of the rear axle. This is primarily influenced by the concentricity of the rear axle relative to the vehicle's centerline. On a solid axle, this means ensuring suspension components (control arms, leaf springs) are not bent or shifted.

Recommended adjustment hardware

Since front camber and caster are not factory-adjustable, aftermarket solutions are often necessary if these angles are out of spec and components are not bent or worn. High-quality eccentric control arm bushings or adjustable ball joints (e.g., from brands like SPC Performance or Moog) can allow for accurate adjustment of front camber and caster, bringing the vehicle back into specification. For the rear, if camber or toe are out, investigation into bent axle components or shifted leaf springs/control arms is necessary.

Symptoms of bad alignment

Ignoring alignment issues can lead to accelerated tire wear, reduced fuel economy, and compromised handling. Here are common symptoms:

• Uneven Tire Wear: This is the most common and tell-tale sign of misalignment. Different alignment issues cause distinct wear patterns:
  • Feathering: Sawtooth-like wear across the tread, often indicating excessive toe-in or toe-out.
  • Camber Wear (one-sided wear): Excessive positive or negative camber causes wear on only one side of the tire (either the inner or outer edge).
  • Cupping/Scalloping: Irregular dips in the tread, often linked to worn suspension components, but can be exacerbated by alignment issues.
• Vehicle Pulling: The vehicle consistently drifts to one side, requiring constant steering correction. This is commonly caused by improper caster or camber settings, or significant cross-camber/caster differences.
• Loose or Wandering Steering: The steering feels vague, and the vehicle struggles to track straight, often due to insufficient caster or excessive toe-out.
• Steering Wheel Not Centered: Even when driving straight, the steering wheel is turned to one side. This is typically a toe issue.
• Squealing Tires: Tires may squeal during turns, even at low speeds, due to excessive toe.

When to align

Regular alignment checks are good preventative maintenance, but certain events absolutely necessitate an alignment:

• After Suspension or Steering Component Replacement: Any work involving steering linkages, control arms, ball joints, tie rods, or other suspension parts will alter alignment angles.
• After Replacing Tires: New tires are an investment; protect them with a fresh alignment.
• After Hitting a Large Pothole or Curb: Significant impacts can bend or shift suspension components, knocking the alignment out.
• Annually or Every 12,000-15,000 Miles: Even without specific incidents, normal wear and tear can gradually throw off your alignment.
• When You Notice Any of the Above Symptoms: Don't wait for tire wear to become severe.

Typical alignment cost

The cost of a wheel alignment for a 2015 Ram 3500 can vary depending on your location, the shop, and whether any adjustments require aftermarket parts. Generally, you can expect to pay between $100 and $200 for a standard two-axle alignment. If aftermarket components are needed to achieve proper specifications (e.g., adjustable ball joints for camber/caster), the cost of parts and labor for installation will be extra.
