Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Tire Check

Step 1: Measure and adjust tire pressures to the recommended PSI using a tire pressure gauge.
Step 2: Inspect each tire for uneven wear or bulges. Replace tires if necessary.

3. Alignment Adjustment

Step 1: Lift the vehicle using a hydraulic jack and secure it on jack stands.
Step 2: Remove the front wheels to access the suspension and alignment components.
Step 3: Using an alignment machine, check the camber, caster, and toe settings.
Step 4: Adjust the tie rods and control arms as needed to meet manufacturer specifications.
- Torque Values: Refer to the service manual for exact torque specifications for tie rod ends and control arm bolts.
Step 5: Reinstall the front wheels and lower the vehicle.

4. Suspension Component Inspection

Step 1: Inspect control arms, bushings, and ball joints for wear or damage.
Step 2: Replace any worn components using a socket set and follow proper torque specifications during reassembly.

5. Brake Inspection

Step 1: Check brake calipers for proper operation and inspect for sticking.
Step 2: Replace calipers if found to be defective.
