2015 Jeep Wrangler Wheel Alignment Specifications

Quick reference

Adjustability

On a 2015 Jeep Wrangler, only front toe is factory adjustable. Caster and camber on both the front and rear axles are non-adjustable from the factory. This means that if your Wrangler exhibits camber or caster issues outside the acceptable range, aftermarket solutions or repair of worn components will be necessary to bring these angles back into spec.

Front toe is adjusted via the tie rod ends, allowing for precise control over the individual and total toe settings. Rear toe and camber, like their front counterparts, are also non-adjustable from the factory. If these rear angles are out of spec, it often indicates worn suspension components or damage that needs to be addressed.

For modified Wranglers, especially those with lift kits, achieving proper alignment can be more challenging. Lift kits often alter static ride height, which can significantly affect caster and camber angles. In these cases, aftermarket adjustable control arms, cam bolts, or eccentric bushings may be required to correct these non-adjustable angles and restore optimal handling and tire wear.

Recommended adjustment hardware

Since only front toe is factory adjustable on a 2015 Jeep Wrangler, correcting other angles typically requires aftermarket solutions. For front camber and caster, common recommendations include:

• Adjustable lower control arms: These allow for significant changes in caster, and to a lesser extent, camber, by changing the effective length of the control arm.
• Offset ball joints: These can provide minor corrections to camber and sometimes caster.
• Cam bolts: While not universally available for all Jeep Wrangler applications from all manufacturers, some cam bolt kits can offer a small range of camber and caster adjustment by allowing the lower control arm bolt to shift within an eccentrically shaped washer.

For rear camber and toe, if they are out of specification due to wear or damage, replacement of the affected components (e.g., control arms, axle housing straightness correction) is often the primary solution, or in some cases, aftermarket adjustable control arms for minor corrections.

Symptoms of bad alignment

Recognizing the signs of a misaligned 2015 Jeep Wrangler can save you money on premature tire wear and improve your driving experience. Here are some common symptoms and their associated tire wear patterns:

• Uneven tire wear: This is the most common indicator. Specific patterns reveal which angle is out of spec:
  • Feathering: When the tread blocks are worn smooth on one side and sharp on the other, it often indicates excessive toe. If the inner edges of the tires are feathered, it's typically excessive toe-out. If the outer edges are feathered, it's usually excessive toe-in.
  • Camber wear: If the inner edge of the tire is significantly more worn than the outer edge (or vice versa), it suggests incorrect camber. Excessive negative camber wears the inner edge, while excessive positive camber wears the outer edge.
  • Cupping or scalloping: These are dips or scoops in the tread around the tire's circumference. While often a sign of worn shocks or unbalanced tires, severe cupping can also be exacerbated by alignment issues, particularly incorrect toe or caster.
• Steering wheel off-center: If your steering wheel is not straight when driving in a straight line, it's a strong indicator of an alignment problem, specifically incorrect total toe.
• Vehicle pulls to one side: If your Wrangler consistently drifts or pulls to the left or right, it can be due to incorrect camber, caster, or cross-camber/caster between the front wheels. A significant thrust angle issue (rear axle not aligned with the vehicle centerline) can also cause a pull.
• Loose or wandering steering: This can be a symptom of insufficient positive caster. If the vehicle feels unstable and requires constant steering corrections to stay straight, caster is a likely culprit.
• Squealing tires: Tires squealing during normal turns can sometimes point to alignment problems, particularly excessive toe or a significant thrust angle.

When to align

It's crucial to have your 2015 Jeep Wrangler's alignment checked and adjusted in several situations to maintain optimal handling, safety, and tire longevity:

• After suspension or steering component replacement: Any time components such as tie rods, ball joints, control arms, or lift kits are installed, an alignment is essential.
• After replacing tires: New tires should always be followed by an alignment check to ensure they wear evenly from the start.
• After an accident or hitting a large pothole/curb: Significant impacts can easily knock your alignment out of spec.
• If you notice any of the alignment symptoms listed above: Early detection can prevent further damage and costly tire replacements.
• As part of routine maintenance: Even without noticeable symptoms, a periodic alignment check (e.g., every 12-15,000 miles or annually) is good practice, especially for off-road vehicles like the Wrangler.

Typical alignment cost

The cost of a wheel alignment for a 2015 Jeep Wrangler can vary depending on your location, the shop, and whether any adjustments beyond front toe are needed (which would involve aftermarket parts and additional labor). Generally, you can expect to pay anywhere from $80 to $150 for a standard four-wheel alignment. If aftermarket adjustable components need to be installed or adjusted, the cost will be higher due to parts and increased labor time.
