How to Remove Citroen Suspension Spheres
The Citroen features a hydro-pneumatic suspension, which was invented by Citroen and has spread to the manufacturing of other vehicle producers, such as Mercedes. The suspension contains a part known as the suspension sphere, which is the mechanism that works as a coil powered by hydraulic fluid and nitrogen gas. Sometimes the sphere wears out and it is neccesary to replace it, which is initiated by removing the sphere.
Supply List
- Wheel ramp
- Strap wrench
- Combination wrench
- O-ring
- LHM fluid (if needed)
- Use a wheel ramp to raise the car off the ground.
- Loosen the suspension sphere--a strap wrench works best.
- Turn the car and allow the engine to continue running.
- Adjust the suspension to the minimal setting. The depressurization causes the vehicle to lower to the ground. Leave the running for a few minutes to ensure the suspension is properly set to minimum.
- Unscrew the bleed bolt. Typically, a combination wrench works best for this purpose.
- Finish loosening the suspension sphere. You need to finish the job, by unscrewing the sphere with your hands. Remove the suspension sphere.
- Take out the O-ring that is within the sphere and discard of it.
- Replace the O-ring with a new O-ring. Insert it from the same place you removed it.
- Check the fluid that is in the suspension system. The liquid hydraulique mineral also referred to as LHM fluid needs checked on a regular basis. This liquid is necessary. Add additional fluid if the levels are lower than normal. Ultimately, this ensures your high-pressure hydraulics work properly.
- Place the suspension itself back where it came from. Use your hands to tighten the sphere. Take a combination wrench to close the bleed bolt. You may roll the car off the ramp now or continue repairing any other spheres within the suspension that may need replaced.
