2015 Ram 2500 Wheel Alignment Specifications

Quick reference

Adjustability

On the 2015 Ram 2500, front alignment adjustability is somewhat limited from the factory. Front camber and caster are not directly adjustable. Instead, these angles are set by the non-adjustable control arm mounts and axle components. If camber or caster falls outside the specified range, it often indicates worn or bent suspension components, or issues with the frame. However, aftermarket solutions like eccentric cam bolts or adjustable control arms are available to provide adjustability for both front camber and caster, allowing for fine-tuning or correction after lift kits or heavy use. Front total toe is adjustable via the tie rod ends.

The rear axle of the 2015 Ram 2500 is a solid axle design, meaning there is no factory adjustment for camber, caster, or toe. The thrust angle, which indicates if the rear axle is tracking straight relative to the vehicle's centerline, is also not adjustable. Any deviations in the rear alignment values typically point to bent axle housings, worn leaf spring bushings, or damaged mounting points. In cases where the thrust angle is off, specialized shops may be able to use shims or custom fabrication to correct the issue, but this is not a routine adjustment.

Recommended adjustment hardware

For a 2015 Ram 2500, if you need to correct front camber or caster beyond factory tolerances, especially after installing a leveling or lift kit, SPC (Specialty Products Company) cam bolts are a popular and effective solution. These bolts replace the original control arm mounting bolts and feature an eccentric lobe that allows for incremental adjustments to camber and caster. Another option for more significant changes, particularly with extensive suspension modifications, would be adjustable upper or lower control arms.

Symptoms of bad alignment

Ignoring alignment issues can lead to accelerated tire wear, poor handling, and reduced safety. Here are some common symptoms:

• Uneven tire wear: This is often the most noticeable sign. "Feathering" (one side of the tread block worn more than the other) or "sawtooth" wear can indicate excessive toe-in or toe-out. Excessive camber will cause wear on either the inner or outer edge of the tire. If only the center of the tire is worn, it often points to overinflation, while wear on both edges suggests underinflation. However, an incorrect alignment can exacerbate these wear patterns.
• Vehicle pulling or drifting: If your Ram 2500 constantly pulls to one side, even on a flat road, your alignment is likely off. This can be caused by incorrect caster, camber, or total toe.
• Steering wheel off-center: When driving straight, a misaligned vehicle may require you to hold the steering wheel at an angle to maintain a straight path.
• Loose or difficult steering: A poor alignment can make the steering feel either excessively loose and vague or surprisingly stiff and heavy.
• Squealing tires: Tires that consistently squeal, especially during turns at normal speeds, can signal alignment problems.

When to align

It's recommended to get an alignment for your 2015 Ram 2500 in several situations:

• After suspension or steering component replacement: Any time you replace parts like tie rod ends, ball joints, control arms, or even shocks/struts, an alignment is crucial.
• After installing new tires: To ensure your new tires wear evenly and last as long as possible, an alignment is a smart investment.
• After hitting a significant pothole or curb: A hard impact can easily knock your suspension out of alignment. If you notice any handling changes after such an event, get it checked.
• At least once a year: Even without specific incidents, roads take their toll. An annual alignment check can catch minor issues before they become major problems.
• When you notice any of the "symptoms of bad alignment" listed above.

Typical alignment cost

The cost of an alignment for a 2015 Ram 2500 can vary depending on your location, the shop, and whether any adjustments are needed beyond a standard front toe adjustment. Generally, you can expect to pay between $80 and $150 for a standard four-wheel alignment. If specialized parts (like cam bolts) or extensive labor are required to correct non-adjustable angles, the cost will be higher.
