Before replacing the relevant parts, use GDS equipment to fully discharge the air from the relevant parts.
(Refer to Air Suspension System - "Repair procedures (Air Injection Procedure)") |
| • |
Be careful when handling the rear air spring, as the lack of
structural reinforcement inside the bellows makes it susceptible to
bending or stretching if subjected to external forces. |
| • |
When removing an air strut, remove the air connector before proceeding with any other work. |
| • |
Make sure that the orientation of the upper and lower part does not twist during assembly. |
