Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Damaged Components

Steering Linkage Inspection:
- Remove any protective covers if necessary.
- Inspect tie rods and steering rack for damage.
- If damaged, replace the affected tie rod or steering rack.
- Tighten all connections to manufacturer specifications (typically around 30-50 Nm for tie rods).
Suspension Component Inspection:
- Remove the front wheels with a socket set.
- Inspect strut assemblies for any signs of bending or damage.
- Check control arms and bushings; replace any that show wear or damage.
- Reassemble and torque the wheel lug nuts to the specified torque (typically around 120 Nm).

3. Wheel Alignment

After replacing components, perform a wheel alignment.
Use a professional alignment tool to ensure the angles are set to manufacturer specifications.
Adjust camber, caster, and toe as necessary.
