Sub-step 3: Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.

3. Replace Faulty Steering Components

Sub-step 1: If the inspection revealed damaged tie rods or steering rack, remove the affected components using the socket set.
Sub-step 2: Install new tie rods or a steering rack, ensuring that each component is torqued to the manufacturer's specifications.
Sub-step 3: Reconnect any removed components such as the steering column and ensure everything is secure.

4. Check and Tighten Suspension Components

Sub-step 1: Inspect bolts and nuts on suspension components for tightness.
Sub-step 2: Tighten any loose bolts to the specified torque values.
Sub-step 3: Replace any worn suspension bushings if necessary.
