Solution

1. Preparation

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

2. Tire Inspection and Replacement

Remove the wheel covers if applicable using a wheel lock key or flathead screwdriver.
Loosen the lug nuts slightly before raising the vehicle with a jack.
Lift the vehicle and secure it on jack stands.
Fully remove the lug nuts and take off the tires.
Inspect each tire for damage, uneven wear, and proper tread depth. Replace if necessary.

3. Suspension Component Inspection and Replacement

Visually inspect struts and shocks for oil leaks or physical damage.
If damaged, use a socket set to remove the bolts securing the struts/shocks to the vehicle.
Replace with new struts/shocks, ensuring proper alignment of mounting points.
Tighten bolts to manufacturer's torque specifications (typically around 50-80 Nm, depending on the component).

4. Alignment Adjustment

After replacing any suspension components, take the vehicle to a professional alignment shop.
Ensure the alignment is adjusted according to BMW's specifications for the X3 G01.

5. Reinstallation

Reinstall the wheels, hand-tightening the lug nuts.
Lower the vehicle and then tighten the lug nuts to the specified torque (usually around 120 Nm).
Reconnect the battery.
