BILSTEIN E4-WM5-Y679A00 Shock Absorbers or Other Suspension Components
IMPORTANT! READ THIS FIRST!
Installation of shock absorbers or other suspension components requires
special tools and expert knowledge. Accordingly, installation of all BILSTEIN
products must be performed by a professional automotive suspension technician.
When replacing other brands, BILSTEIN shock absorbers or other suspension
components should always be installed as a set. All BILSTEIN products must
only be used for the specific, intended application as indicated in the
application guide. Any use of any BILSTEIN product other than for its intended
use may result in serious bodily injury or death.
Always use a chassis hoist for the installation of BILSTEIN products and make
certain that the raised vehicle is securely attached to the hoist and/or
supported to prevent the vehicle from slipping, falling, or moving during the
installation process.
If you install any BILSTEIN product without the necessary special tools,
expertise, and chassis hoist, you may subject yourself to the risk of serious
bodily injury or death.
BILSTEIN shock absorbers are gas-filled and are highly pressurized.
- Never place any BILSTEIN shock absorbers in a vise or use a clamp on any BILSTEIN shock absorber.
- Never apply heat near any BILSTEIN shock absorber.
- Never attempt to open or repair any BILSTEIN product, in order to prevent serious bodily injury or death.
Any attempt to misuse, misapply, modify, or tamper with any BILSTEIN suspension product voids any warranty and may result in serious bodily injury or death.
While installing any BILSTEIN product:
- Do not use impact tools for loosening or tightening fasteners, because this may destroy the screw threads.
- Self-locking fasteners must only be used once!
- Reuse original equipment components only if they are in good condition, otherwise replace them with new components.
- Never remove the slight film of oil on the shock absorber piston rod and seal.
- All mounting fasteners for shock absorbers and other suspension components must be securely tightened before tension is placed on the suspension system, unless otherwise specified in the manufacturer’s service manual or in this instruction.
After installing any BILSTEIN product:
- The suspension caster and camber must be checked and/or adjusted to comply with the vehicle manufacturer’s specifications.
- The (load dependent) brake compensator and the anti-lock brake system must be checked and/or reset to comply with the vehicle manufacturer’s specifications.
- The headlight aim must be checked and adjusted
CAUTION for COILOVER TYPE SUSPENSIONS!!!
If disassembling a coil over type suspension, refer to the vehicle
manufacturer’s service manual for proper procedures. The coil spring is
preloaded and must be compressed with a spring compressor to release load
before the upper mount is disassembled. Failure to follow the vehicle
manufacturer’s procedures may cause serious injury or death, and may damage
the vehicle.
IMPORTANT!!!
This BILSTEIN product may or may not be compatible with non-BILSTEIN
aftermarket products and/or vehicle modifications. It is the responsibility of
the professional automotive suspension technician performing the installation
to identify any non-OEM components and/or modifications on the vehicle that
may interact with the suspension system. These must be evaluated for any
potential physical static or dynamic interference with and/or effect on the
function of this BILSTEIN product.
