Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery if necessary for electronic steering components.

2. Inspect and Replace Worn Components

Suspension Component Inspection
- Use a jack to lift the vehicle and secure it with jack stands.
- Inspect control arms, bushings, and tie rods for any signs of damage or excessive wear.
- Replace any worn or damaged components using a socket set and torque wrench to manufacturer specifications.
Steering Component Inspection
- Examine the steering rack and associated joints for play and damage.
- If the steering rack is faulty, remove it by disconnecting the steering column and securing bolts.
- Install a new steering rack, ensuring all connections are tight and torque to specifications.

3. Wheel Alignment

Initial Setup
- Mount the vehicle on an alignment rack and ensure all wheels are straight.
- Follow the manufacturer’s specifications for alignment angles (caster, camber, toe).
Adjust Alignment
- Adjust the tie rods to achieve the correct toe settings.
- Make necessary adjustments to camber and caster using the appropriate tools.
- Lock all adjustments securely and verify alignment settings.
Final Checks
- Recheck torque on all suspension and steering components.
- Lower the vehicle and do a road test to ensure proper steering response.
