Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Wear safety gloves and goggles for protection.

2. Tire Inspection and Adjustment

Sub-step 1: Check and adjust tire pressures to the recommended levels. Use a tire pressure gauge for accuracy.
Sub-step 2: Inspect each tire for uneven wear patterns. If uneven wear is noted, rotate the tires as needed.
Tools Required: Tire pressure gauge, air compressor.

3. Alignment Adjustment

Sub-step 1: Using the alignment machine, check the alignment settings against the manufacturer's specifications.
Sub-step 2: If misalignment is found, adjust the camber, caster, and toe settings as required using the proper tools.
Sub-step 3: Confirm all bolts are torqued to the manufacturer-recommended specifications.
Tools Required: Alignment machine, torque wrench, socket set.

4. Suspension and Brake Inspection

Sub-step 1: Inspect suspension components (control arms, bushings, struts) for damage or wear.
Sub-step 2: If any components are worn or damaged, replace them accordingly.
Sub-step 3: Check brake calipers for proper function. Ensure they are not sticking; replace if necessary.
Tools Required: Socket set, jack and jack stands, brake cleaner.
