BMW X5: Information On Replacing Shock Absorbers

Facts:

When a shock absorber is faulty on one side (leaking, noises, limit values exceeded on the shock tester), often both shock absorbers on the axle in question are replaced.

Consequence:

This is not necessary for technical reasons and causes the manufacturer not to recognize the unnecessarily removed shock absorbers as damaged parts. Unnecessarily high costs for the customer can be avoided by replacing the shock absorber on one side only.

Procedure:

Shock absorbers may be replaced on one side only until they have completed 50 000 km service.

Exception: On all M-GmbH models, when a limit value is exceeded on one side, it is still necessary always to replace both shock absorbers on the relevant axle.

INSTRUCTIONS (CHASSIS COMPONENTS MADE OF ALUMINUM)

Due to the chemical and corrosion characteristics of aluminum, always comply with the following points when handling aluminum components:

• Do not bring into contact with battery acid!
• Do not clean with wire brushes made of brass or iron! Always use wire brushes with stainless steel bristles!
• Do not expose to flying sparks when grinding/separating! Cover components!
• Do not strike with steel welding splashes! Cover components!
• Do not expose to temperatures > 80 ºC, even for brief periods! Temperatures in paint facilities do not have the same impact

NOTES ON REPAIRING THREADS

IMPORTANT: Install Heli-coil thread inserts so that they are flush with the original thread.

Comply with the procedure described in the example.
