why does my BMW X3 G01 (2018-2024) rear end make noise when driving

Solution

1. Preparation

• Tools Required:
  • Jack and jack stands
  • Socket set
  • Torque wrench
  • OBD-II scanner
• Ensure the vehicle is on a level surface and secure before starting work.

2. Inspect Rear Suspension

• Sub-steps:
  1. Lift the vehicle using a jack and secure it with jack stands.
  2. Visually inspect the rear suspension components including control arms, bushings, and shock absorbers for any signs of wear or damage.
  3. If any components are worn, replace them with OEM parts.

3. Check Exhaust System

• Sub-steps:
  1. Inspect the exhaust system from the rear to the front for any loose hangers or damaged sections.
  2. Tighten any loose connections and replace damaged parts as necessary.

4. Inspect Differential Fluid

• Sub-steps:
  1. Locate the rear differential and remove the fill plug.
  2. Check the fluid level; it should be at the fill level.
  3. If low, drain the old fluid, inspect for metal shavings, and refill with the manufacturer-recommended differential fluid.

5. Brake Inspection

• Sub-steps:
  1. Remove the rear wheel to access the brake assembly.
  2. Inspect brake pads for wear; replace if they are worn down.
  3. Check the brake hardware for looseness and tighten or replace as needed.
