Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turn off the engine.
Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Engine Mounts (if necessary)

Sub-steps:
- Remove any components obstructing access to the engine mounts (air intake assembly, battery, etc.).
- Inspect engine mounts for cracks, tears, or excessive wear.
- If defective, remove the bolts securing the engine mount to the engine and chassis.
- Replace with new engine mounts and torque bolts to manufacturer specifications (typically around 30-50 Nm).

3. Check and Adjust Wheel Alignment

Sub-steps:
- Lift the vehicle and remove the front wheels.
- Inspect suspension components for wear (ball joints, tie rods).
- Adjust alignment settings according to manufacturer specifications (camber, caster, toe).
- Reinstall wheels and torque lug nuts to manufacturer specifications (usually 110-130 Nm).

4. Balance Wheels

Sub-steps:
- Remove the wheels from the vehicle.
- Take wheels to a tire balancing machine.
- Balance each wheel and tire assembly until within acceptable limits.
- Reinstall wheels and torque lug nuts as previously stated.

5. Power Steering Fluid Inspection

Sub-steps:
- Locate the power steering fluid reservoir.
- Check the fluid level; if low, top up with the recommended fluid type (usually CHF 202 or equivalent).
- Inspect for leaks in the power steering system, including hoses and the pump.
