Here are the most common culprits:
* Worn Ball Joints: Worn ball joints allow excessive movement in the suspension, leading to changes in camber. This is a very common cause of alignment issues.
* Worn Control Arm Bushings: Similar to ball joints, worn bushings allow excessive play in the suspension, affecting camber alignment. These bushings are rubber and deteriorate over time.
* Bent Control Arms: Impact damage (like hitting a pothole or curb hard) can bend the control arms, permanently altering the camber.
* Bent Steering Knuckles: Another potential result of impact damage, a bent knuckle will directly affect wheel alignment, including camber.
* Worn or Damaged Tie Rod Ends: While primarily affecting toe, severely worn tie rod ends *can* indirectly influence camber by altering the overall geometry of the suspension.
* Frame Damage: Significant frame damage from an accident can affect the alignment of the entire suspension system, including camber.
* Incorrect Installation of Parts: If you've recently replaced any suspension components, an incorrect installation could be the cause.
* Excessive Off-Roading: Aggressive off-roading puts significant stress on suspension components, potentially leading to wear or damage that throws the camber off.
Diagnosing the Problem:
You'll need to have a qualified mechanic inspect your truck to pinpoint the exact cause. Visually inspecting the suspension components for damage or wear is the first step. They'll likely perform a thorough alignment check and may use specialized tools to measure the play in ball joints and bushings.
Important Note: Driving with incorrect camber can lead to uneven tire wear, reduced handling, and potentially dangerous driving conditions. Don't delay getting it fixed.
