The process involves adjusting various components that affect the suspension geometry, including camber, caster, and toe angles. Below is a detailed description of the components involved and the steps necessary to perform a suspension alignment.

### Components Involved in Suspension Alignment

1. **Camber**:
– The angle of the wheels in relation to the vertical axis when viewed from the front of the vehicle. Positive camber means the top of the wheel is tilted outward; negative camber means it’s tilted inward.
– For Jeep Cherokee XJ and Wrangler YJ, recommended camber is typically close to zero But may vary slightly based on the lift and tire setup.

2. **Caster**:
– The angle of the steering axis when viewed from the side of the vehicle. Positive caster means the steering axis tilts toward the driver. This helps with stability and steering return.
– For the XJ and YJ, a positive caster angle is beneficial, usually between 4 to 7 degrees.

3. **Toe**:
– The angle of the wheels in relation to the centerline of the vehicle when viewed from above. If the front of the wheels is closer together than the rear, it’s called “toe-in,” and if they are farther apart, it’s called “toe-out.”
– The recommended toe setting is usually around 1/16 inch to 1/8 inch toe-in for both models.

4. **Adjustable Components**:
– **Control Arms**: These connect the axle to the frame. Adjustable control arms can help fine-tune caster and camber angles.
– **Track Bar**: This connects the axle to the frame laterally, helping to center the axle under the vehicle. Adjusting the track bar can help with overall alignment.
– **Tie Rods**: These connect the steering mechanism to the wheels and are adjustable to set toe angles.

5. **Suspension and Steering Components**:
– **Ball Joints**: These allow for movement in the suspension and steering. Worn ball joints can lead to alignment issues.
– **Bushings**: These provide flexibility in suspension components. Worn bushings can affect alignment.
– **Wheel Bearings**: Properly functioning wheel bearings are essential for maintaining alignment.
