* Shims: The most common method involves adding or removing shims from the upper control arm mounting points. These shims are thin metal plates that alter the angle of the control arm, thus adjusting the camber. This requires removing the upper control arm, adding or removing shims, and re-installing the arm. It's a significant job requiring specialized tools and a good understanding of suspension geometry.
* Control Arm Bushings: Worn control arm bushings can also affect camber. Replacing worn bushings might improve camber but won't allow for fine adjustments. If they're significantly worn, replacement is necessary for proper handling and suspension function regardless of camber adjustments.
* Aftermarket Parts: Some aftermarket companies offer adjustable control arms for these trucks. These allow for more precise camber adjustment, but they are a much more costly solution involving a complete replacement of the factory control arms.
Important Considerations:
* Safety: Working on your suspension requires mechanical aptitude and safety precautions. If you're not comfortable working on your vehicle's suspension, it's strongly recommended to take it to a qualified mechanic. Improper adjustment can severely affect handling and safety.
* Tools: You will need specialized tools including, but not limited to: jack stands, socket sets, wrenches, possibly a ball joint separator, and a camber gauge (to actually measure the camber before and after adjustments).
* Alignment: After adjusting camber, you must have a wheel alignment done by a professional. Camber is only one aspect of a proper wheel alignment. Incorrect caster and toe will severely affect your handling, tire wear, and vehicle safety.
* Year and Model Specifics: The exact procedure will vary slightly depending on the exact year and model of your 1988 Chevy truck (e.g., C10, C1500, C2500, etc.). A repair manual specific to your truck's year and model is essential for accurate instructions.
In short: Adjusting camber on an '88 Chevy truck is a relatively advanced repair that's best left to experienced mechanics unless you have substantial automotive experience and the correct tools. Attempting this without the proper knowledge and tools can lead to damage to your vehicle and potential safety hazards. The cost of a professional alignment will be far less than the cost of repairing damage caused by an improperly performed adjustment.
