Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repair.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level.
3. If low, use a turkey baster to remove old fluid and refill with manufacturer-recommended power steering fluid (e.g., BMW CHF 11S).

3. Replace Worn Steering Components

Sub-steps:
1. If any components (tie rods, bushings, or rack and pinion) are found damaged, raise the vehicle and secure it on jack stands.
2. Remove the wheels to access the steering components.
3. Disconnect the tie rods from the steering rack and remove them.
4. Replace any worn components with OEM parts, ensuring proper alignment.
5. Reassemble in reverse order and torque the fasteners to manufacturer specifications.

4. Align Steering Wheel

Sub-steps:
1. After repairs, check if the steering wheel is centered when driving straight.
2. If misaligned, adjust the tie rods equally to center the steering wheel.
3. Confirm alignment with a professional alignment tool or through a certified alignment shop.
