Problem Statement

The struts on a 2019-2024 BMW X5 G05 appear to be leaking, indicating potential fluid loss and compromised suspension performance.

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Always use jack stands when working under a vehicle.

Symptoms

•Visible fluid accumulation on strut bodies
•Reduced ride comfort or increased bounciness
•Uneven tire wear
•Clunking noises over bumps
•Vehicle sagging on one side

Diagnostic Steps

1
Inspect the struts visually for any signs of fluid leakage.
2
Check for any damaged or worn bushings and mounts associated with the struts.
3
Verify the strut assembly by compressing it to see if it returns smoothly without sticking.
4
Examine surrounding components for signs of oil contamination or damage.
5
Inspect the vehicle’s suspension alignment to identify any underlying issues.

Solution

Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a strut spring compressor.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle (depending on which strut is leaking).
Secure the vehicle with jack stands to prevent it from falling.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel to access the strut assembly.

4. Remove the Strut Assembly

Disconnect the lower strut mounting bolts using the socket set.
Remove the upper strut mounting nuts from the strut tower.
Carefully detach the strut assembly from the vehicle.

5. Inspect and Replace

Inspect the strut for any signs of internal damage.
If leaking, replace the strut with a new unit:
- Remove the spring using a strut spring compressor.
- Install the spring onto the new strut and ensure it is secure.
- Reinstall the strut into the vehicle, reversing the removal steps.

6. Reassemble and Torque

Reattach the upper and lower strut mounting bolts.
Torque the bolts to the manufacturer specifications (specific torque values can be found in the service manual).
Reinstall the wheel and lug nuts, then lower the vehicle back to the ground.
