How to Adjust Camber Bolts: What They Do and How the Process Works
Camber bolts are one of the more accessible alignment tools available to DIYers and shops alike — but using them correctly requires understanding what they're actually doing to your suspension geometry. Get it wrong, and you'll wear through tires faster than you'd expect.
What Is Camber, and Why Does It Matter?
Camber is the inward or outward tilt of a wheel when viewed from the front of the vehicle. A wheel that tilts outward at the top has positive camber. One that tilts inward has negative camber.
Most passenger vehicles are designed to run close to zero degrees of camber — slight variations are normal, but significant camber misalignment causes uneven tire wear, pulling to one side, and reduced cornering stability. Camber shifts out of spec after suspension component wear, collision damage, or vehicle lowering.
What Camber Bolts Actually Do
Standard factory bolts hold suspension components — typically the strut to the steering knuckle, or control arm mounting points — in a fixed position. Camber bolts replace those standard bolts with an eccentric design: an off-center cam or lobe built into the bolt head or washer. When you rotate the bolt, that offset cam shifts the component's mounting position slightly, moving the wheel in or out at the top to change camber angle.
They're a corrective tool, not a precision engineering solution. They work within a limited range — typically ±1.0 to ±1.5 degrees depending on the bolt design — which is enough to bring most vehicles back into spec, but not enough to address severe misalignment caused by bent suspension components.
Tools and Preparation
Before touching a camber bolt, you need:
- A wheel alignment gauge or digital angle finder — adjusting camber without measuring it is guesswork
- A torque wrench — final torque specs matter significantly here
- Basic hand tools (breaker bar, appropriate sockets)
- A lift, jack stands, or access to a shop lift
- The vehicle's factory alignment specifications (found in the service manual or often on a sticker in the door jamb or engine bay)
⚙️ If you don't have a way to measure camber angle during the adjustment, the process loses most of its value.
How the Adjustment Process Works
Step 1: Loosen the Bolt
With the vehicle safely lifted and the wheel removed (on most setups), locate the camber bolt — commonly at the top strut-to-knuckle pinch bolt location on MacPherson strut suspensions, or at control arm mounting points on double-wishbone setups. Loosen the bolt enough to allow the cam to rotate, but don't remove it entirely. The component needs to stay loosely seated while you make the adjustment.
Step 2: Rotate the Cam
The eccentric cam on the bolt has a hex head or flat that you rotate to move the mounting position. Turning the cam shifts the knuckle or control arm, which changes the wheel's camber angle. Most bolts include a scale or index marks to help track rotation. Small movements create meaningful changes — a quarter turn can shift camber by half a degree or more depending on bolt design.
Step 3: Measure as You Go
Check camber angle with your gauge after each incremental adjustment. The goal is to match the vehicle manufacturer's specified camber angle — not just get "close." On vehicles with independent rear suspension, front and rear camber are both adjustable on some platforms.
Step 4: Torque to Spec
Once the target angle is reached, torque the bolt to the manufacturer's specification while holding the cam in position. This is the step most DIYers rush — backing off even slightly during final torque shifts the adjustment. Many mechanics will hold the cam with one wrench while torquing with another.
Step 5: Recheck After Torque
Torquing can move things slightly. Recheck camber once the bolt is fully tightened. If it's shifted outside of spec, loosen slightly, readjust, and re-torque.
Variables That Affect Outcomes 🔧
No two camber bolt jobs are identical. Key factors include:
| Variable | Why It Matters |
|---|---|
| Suspension design | MacPherson struts, double-wishbone, and multilink setups each have different bolt locations and adjustment ranges |
| Vehicle age and rust | Corroded bolts and seized components significantly complicate the process |
| How far out of spec | Camber bolts have a limited correction range — some misalignment requires more than a bolt swap |
| Lowered vehicles | Springs and coilovers often push camber well outside the bolt's correction range |
| Bolt brand and design | Correction range and cam design vary by manufacturer |
A vehicle with worn ball joints, a bent control arm, or a damaged strut tower will not hold alignment regardless of what the camber bolts do. Underlying damage has to be addressed first.
When Camber Bolts Aren't Enough
If the vehicle has been in a collision, has a twisted subframe, or has suspension components that are visibly bent or excessively worn, camber bolt adjustment is a temporary patch at best. The same applies if the desired correction exceeds the bolt's adjustment range — adding a second set of aftermarket components or replacing damaged parts becomes necessary.
Alignment specs, vehicle suspension geometry, and the degree of existing misalignment all determine whether camber bolts are the right fix or just part of the solution. What's sufficient for one vehicle and situation may fall short for another.
