Information
Before any diagnosis of the front lift system takes place, the front shocks should be
inspected to confirm they have not been modified. The E60 front lift system shocks
should not be modified to lower the vehicle in any way. Lowering the lift actuator may
cause internal damage to the part.
Repairs to the front lift system after the shocks modification should NOT be submitted as
a warranty repair.
Damage to suspension components caused by modifying vehicle height outside of
factory settings will not be covered by the vehicle warranty.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
