How To Adjust Camber On A Car: A Professional Wheel Alignment Guide

Adjusting wheel camber involves measuring the vertical tilt of the tire using a precision camber gauge and modifying the vehicle's adjustment points, such as eccentric cam bolts, adjustable control arms, or upper camber plates. For standard street vehicles, camber should typically be set between -0.5 and -1.5 degrees to ensure balanced tire wear and stable lateral tracking. This adjustment must always be finalized with a calibrated torque wrench to manufacturer specifications and followed immediately by a toe-in correction to preserve steering geometry.

Pre-Alignment Diagnosis & Required Equipment

Before attempting a camber adjustment, you must assess the condition of your vehicle’s suspension system. Adjusting camber on worn, damaged, or sagging components is counterproductive; any play in the control arm bushings, ball joints, or wheel bearings will invalidate your measurements.

Begin by parking the vehicle on a perfectly level surface. This is a critical prerequisite, as even a one-degree slope in your garage floor will skew your camber readings. Use a digital level to verify the lateral flatness of the work area. If necessary, shim the tires with thin plywood or linoleum tiles to create a perfectly level platform.

Step-by-Step Guide to Adjusting Wheel Camber

Step 1: Establish Baseline Measurements

To get an accurate initial reading, the suspension must be fully loaded and settled. Roll the vehicle forward and backward over your greased slip plates. This relieves any lateral bind in the tire sidewalls caused by jacking up the car.

Attach your digital camber gauge directly to the brake rotor or the outer lip of the wheel rim using the magnetic adapter. Ensure the gauge is perfectly vertical and perpendicular to the ground. Read and record the current camber angle for all four wheels.

Pro-Tip: Make sure your steering wheel is locked dead-center before taking your baseline measurements. A turned wheel introduces steering axis inclination (SAI) and caster into the camber reading, rendering it highly inaccurate.

Step 2: Lift and Secure the Vehicle

Loosen the wheel lug nuts slightly if you must remove the wheels to access the adjustment points. Position your hydraulic floor jack under the manufacturer-designated jacking points. Lift the vehicle and lower it securely onto jack stands.

Never rely on the jack alone to support the weight of the car while you work underneath. If your suspension configuration requires you to make adjustments with the wheels off, you will need to support the lower control arm with a secondary jack to simulate the vehicle's ride height and keep the suspension geometry loaded.

Step 3: Access and Loosening the Adjustment Point

Identify the mechanism your vehicle uses to adjust camber. This varies significantly by design:

1. MacPherson Strut Systems: Usually adjusted via the upper bolt connecting the lower strut bracket to the steering knuckle. If your car does not have OEM camber adjustment here, you must install aftermarket eccentric "crash bolts."
2. Double-Wishbone Systems: Typically adjusted via eccentric cam bolts located at the inner pivots of the lower or upper control arms, or by inserting/removing shims behind the upper control arm pivot shaft.
3. Aftermarket Camber Plates: Located at the top of the strut tower in the engine bay, allowing the entire strut top mount to slide inward or outward along slotted holes.

Apply a generous coating of penetrating fluid to the fasteners. Using a breaker bar and the correct socket size, loosen the locking nut of the adjustment bolt just enough to allow the bolt to rotate. Do not remove the nut entirely.

Step 4: Executing the Camber Adjustment

Rotate the eccentric bolt or slide the adjustment mechanism to change the angle of the wheel.

• To increase negative camber (tilt the top of the tire inward): Rotate the eccentric bolt so the cam lobes push the top of the steering knuckle inward toward the engine, or slide your upper camber plate toward the center of the engine bay.
• To increase positive camber (tilt the top of the tire outward): Push the knuckle outward or slide the camber plate away from the engine bay center.

If adjusting via aftermarket adjustable control arms, loosen the lock nuts on the turnbuckle and rotate the center sleeve to lengthen or shorten the arm. Lengthening an upper arm or shortening a lower arm pushes the wheel toward positive camber, and vice versa.

Monitor your digital gauge continuously during this process if you are working with the suspension loaded on a drive-on lift. If the car is on jack stands, make a small, incremental adjustment, snug the bolts, lower the vehicle back onto the slip plates, bounce the suspension to settle it, and measure. Repeat this iterative process until the target angle is reached.

Warning: Do not exceed the maximum adjustment range of your hardware. Forcing an eccentric bolt past its designed rotation point can strip the locating tabs on the subframe or damage the bolt threads, leading to sudden alignment failure while driving.

Step 5: Torquing to Spec & Final Verification

Once the target camber angle is achieved, use a torque wrench to tighten the adjustment nuts to the exact torque specifications outlined in your service manual. For most strut-to-knuckle clevis bolts, this range is between 75 and 110 lb-ft. For control arm pivot bolts, it is typically between 55 and 85 lb-ft. Tightening these components while the suspension is in its loaded state prevents bushing bind and premature bushing tear.

Lower the vehicle back onto the ground, bounce the suspension several times to settle the springs, and take your final camber readings.

Because camber adjustments directly alter the steering toe angle, you must now measure and adjust your toe-in. A negative camber change generally causes the wheels to toe out. Use a tape measure or toe plates to verify and adjust the tie rod ends to bring your toe back to the factory-specified range (usually between 0.05 and 0.15 degrees toe-in for rear-wheel-drive cars).

Suspension Geometry & Camber Specifications

The target camber angle depends heavily on your vehicle's drivetrain layout, suspension design, and intended use. The table below outlines standard ranges and the physical trade-offs associated with each setup.

Common Suspension Alignment Failures & Remedies

The Camber Slips or Changes After Driving

• Root Cause: The friction-locking surface of the eccentric cam washer has flattened, or the lock nuts were not torqued under load. Under lateral cornering forces, the hardware slips within its slotted mounting hole.
• Actionable Fix: Replace the worn eccentric bolts with high-tensile strength, class 10.9 or 12.9 hardware. Clean all grease and rust scale off the subframe mounting brackets, install hardened lock washers, and torque the fasteners to the upper limit of the manufacturer's specification.

Camber Cannot Reach Spec Even with Adjustment Hardware Maxed Out

• Root Cause: Bent structural components, such as a deformed steering knuckle, a buckled strut body from hitting a pothole, or collapsed control arm bushings.
• Actionable Fix: Conduct a thorough inspection of the suspension components. Measure and compare the distance between symmetrical points on the left and right sides of the suspension. Replace any bent parts. If the chassis has experienced minor deformation, install aftermarket adjustable upper control arms or slotted camber plates to restore the necessary adjustment range.

Severe Vehicle Pull to One Side Post-Adjustment

• Root Cause: Asymmetrical camber or caster angles between the left and right wheels (cross-camber/cross-caster exceeding 0.5 degrees), or a severe steering toe imbalance created during the camber change.
• Actionable Fix: Re-measure both front wheels. Ensure that the difference in camber between the left and right sides is less than 0.25 degrees. Next, perform a manual toe alignment on both sides of the vehicle to center the steering rack and equalize the toe angles.

Frequently Asked Questions

Can I adjust camber at home without professional alignment equipment?

Yes, you can adjust camber at home using a digital level, a magnetic camber gauge, and DIY slip plates. While this method requires patience and an iterative measurement process, it can yield professional-grade precision if performed on a perfectly flat surface with calibrated DIY tools.

Does adjusting camber affect toe?

Yes, any change to the camber angle will directly alter the toe angle. When you tilt the top of the wheel inward (negative camber), it pushes the steering arm forward or backward relative to the steering rack, which changes the toe. Always adjust camber first, caster second, and finish with a final toe alignment.

Why does my car pull to one side after a camber adjustment?

A pull to one side is typically caused by uneven camber between the front wheels (known as cross-camber) or an uncorrected toe imbalance. A vehicle will naturally pull toward the side with more positive (or less negative) camber. Ensure your left and right camber values are within 0.25 degrees of each other.

What is the difference between positive and negative camber?

Positive camber occurs when the top of the wheel tilts outward away from the vehicle center, which is sometimes used on utility vehicles to compensate for heavy loads. Negative camber occurs when the top of the wheel tilts inward toward the engine bay, which improves cornering grip by resisting lateral forces.
