Solution

1. Preparation

Gather necessary tools: socket set, torque wrench, alignment tools, and a jack with jack stands.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Steering Components

Sub-step 1: Raise the front of the vehicle using a jack and secure it with jack stands.
Sub-step 2: Visually inspect the steering rack, tie rods, and other steering components for any signs of damage or wear.
Sub-step 3: Wiggle the steering wheel while observing the steering linkage for play or movement.

3. Tighten Components

Sub-step 1: Using a socket set, check and tighten all steering rack mounting bolts to the manufacturer’s torque specifications (typically around 30 Nm, but verify in the service manual).
Sub-step 2: Ensure all tie rod ends are secure and free of play. Replace any worn components as necessary.

4. Address Suspension Issues

Sub-step 1: Inspect and replace any worn bushings or ball joints within the suspension system.
Sub-step 2: If any components are found to be defective, replace them and ensure they are properly torqued.

5. Wheel Alignment

Sub-step 1: After addressing all steering and suspension issues, perform a wheel alignment using an alignment machine.
Sub-step 2: Adjust the alignment settings to match the manufacturer specifications.
