How to Adjust Camber on a Car: What It Is, How It Works, and What Changes It
Camber is one of those alignment angles most drivers never think about — until their tires start wearing unevenly, or the car starts pulling to one side. Understanding how camber works, why it gets out of spec, and how it's corrected helps you make sense of what an alignment shop is actually doing.
What Is Camber?
Camber refers to the vertical tilt of a wheel when viewed from the front of the car. If the top of the wheel leans outward from the vehicle, that's positive camber. If it leans inward, that's negative camber. If the wheel stands perfectly straight up and down, camber is zero.
Most passenger cars are set to a slight negative camber — typically between 0 and -1.5 degrees — because it improves cornering grip and tire contact under load. Performance and track-oriented vehicles sometimes run more aggressive negative camber (-2 to -4 degrees) to maximize cornering performance, though this accelerates inner tread wear in daily driving.
Camber matters for three main reasons:
- Tire wear — Incorrect camber causes uneven wear across the tread face
- Handling — Misaligned camber affects how the car tracks and corners
- Suspension load — Camber out of spec puts uneven stress on wheel bearings, ball joints, and tie rods
Why Camber Falls Out of Spec
Camber doesn't drift on its own under normal conditions — something usually causes it. Common culprits include:
- Hitting a pothole or curb hard — can bend control arms, struts, or knuckles
- Worn suspension components — bushings, ball joints, and strut mounts degrade over time
- Sagging springs — as springs lose height with age, camber angles shift
- Collision damage — even minor impacts can alter alignment geometry
- Lifted or lowered vehicles — any change in ride height affects camber
How Camber Is Measured
Before anything is adjusted, a technician puts the vehicle on an alignment rack — a set of sensors attached to each wheel that communicates with a computer to measure all four alignment angles simultaneously: camber, toe, and caster. These three angles work together, and changing one can affect another.
The computer compares the measured angles against the OEM (original equipment manufacturer) specifications for that specific vehicle. Most manufacturers publish acceptable ranges, not just a single target number.
How Camber Is Actually Adjusted ⚙️
This is where it gets complicated — because not every vehicle has adjustable camber from the factory. How camber is corrected depends entirely on the suspension design.
Vehicles With Built-In Camber Adjustment
Some vehicles are designed with camber adjustment built into the suspension. Common methods include:
- Eccentric bolts or cam bolts — slotted or offset bolt holes on strut mounts or control arm brackets that allow the assembly to shift slightly when loosened
- Adjustable upper control arms — found on many trucks, SUVs, and performance vehicles with double-wishbone or multi-link suspension
- Strut top plates — some front-strut designs allow the strut tower bolt position to be shifted
On these vehicles, a technician loosens the relevant fasteners, shifts the component to bring camber into spec, and re-torques everything. It's straightforward work on an alignment rack.
Vehicles Without Factory Camber Adjustment
Many economy cars and front-wheel-drive vehicles with MacPherson strut suspension have no factory camber adjustment. The geometry is fixed by design. If camber is off on one of these vehicles, it usually means something is bent, worn, or damaged — and the fix is replacing the damaged component, not adjusting a bolt.
However, the aftermarket offers solutions for these vehicles:
| Adjustment Method | How It Works | Typical Use Case |
|---|---|---|
| Camber bolts | Eccentric bolts replace stock strut bolts, allowing small angle changes | Minor correction on strut-style suspensions |
| Camber plates | Aftermarket strut top mounts with slotted adjustment | Performance builds, lowered vehicles |
| Adjustable control arms | Replace OEM arms with length-adjustable aftermarket versions | Lifted/lowered trucks, performance vehicles |
| Shims | Thin metal shims inserted at control arm mounting points | Some older vehicles and light trucks |
The right solution depends on the suspension type, how far the camber is out, and whether there's underlying damage that needs to be addressed first.
DIY vs. Professional Alignment 🔧
Technically, someone with basic mechanical skills can install camber bolts or adjustable components. But setting the actual angle accurately requires an alignment rack. Eyeballing camber or using a basic angle gauge is not a substitute for machine measurement — small errors compound across all four wheels and affect how the car drives.
A full four-wheel alignment on an alignment rack is how camber is properly verified and set. Costs vary by region, shop, and vehicle type, but a standard alignment generally runs between $75 and $150 at most shops. Vehicles requiring additional parts — camber bolts, replacement control arms — add to that cost.
The Variables That Shape Your Situation
Whether adjusting camber is simple or complicated comes down to several factors:
- Suspension design — strut vs. double-wishbone vs. multi-link changes what's adjustable
- Whether something is bent or worn — adjustment can't substitute for a damaged component
- How far out of spec camber is — a small drift may be correctable; a large deviation points to damage
- Vehicle height — lowered or lifted vehicles often need custom solutions
- Front vs. rear — rear camber adjustment is often more limited, especially on FWD vehicles
What's a quick camber bolt swap on one car is a control arm replacement job on another. The suspension geometry under your specific vehicle, and whatever caused the camber to shift in the first place, determines what the actual correction looks like.
