why does my BMW X3 G01 (2018-2024) steering wheel shake while braking

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery (optional for electronic components).

2. Inspect and Replace Brake Rotors

1. Lift Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
2. Remove Wheel: Use a socket set to remove the wheel lug nuts and take off the wheel.
3. Inspect Rotors: Check for warping using a dial indicator or visually inspect for grooves and uneven wear.
4. Replace Rotors (if needed):
   • Remove caliper mounting bolts using a socket.
   • Carefully slide the caliper off the rotor.
   • Remove the rotor from the hub.
   • Install a new rotor, ensuring it is free of debris.
   • Reinstall the caliper and secure with bolts to manufacturer’s torque specifications.

3. Check and Replace Brake Pads

1. Inspect Brake Pads: Look for uneven wear or contamination.
2. Replace Pads (if necessary):
   • Remove the caliper as described above.
   • Slide out the old brake pads.
   • Install new pads, ensuring they are properly seated and aligned.
   • Reassemble the caliper and secure it with bolts.

4. Wheel Alignment and Balancing

1. Check Alignment: Take the vehicle to a professional for alignment if uneven tire wear is noted.
2. Balance Wheels: Ensure all wheels are properly balanced to prevent vibrations.

5. Inspect Suspension Components

1. Visual Inspection: Check for worn or damaged components like tie rods, control arms, and bushings.
2. Replace Worn Parts: If any components are found to be defective, replace them as necessary.

Tools Required:

• Jack and jack stands
• Socket set
• Torque wrench
• Brake cleaner
• Dial indicator (for rotor inspection)

Parts Required:

• Brake rotors (if warped)
• Brake pads (if worn)
• Alignment shims (if needed)

Estimated Repair Time: 2-4 hours

Safety Warnings:

• Ensure the vehicle is securely lifted before working underneath.
