32–00 Safety Precautions
Safety Precautions in this section apply to all
procedures within this group.
DANGER
Electric vehicles are equipped with a high-voltage
system. Do not attempt any type of electrical work
on the vehicle unless you have completed HV3
Daimler Safety Training. Failure to do so could
cause severe personal injury or death.
When working on the vehicle, shut down the
engine or motor, set the parking brake, and chock
the tires. Before working on the vehicles, always
place jack stands under the frame rails to ensure
the vehicle cannot drop. For an electric vehicle,
decommission the vehicle and verify the high-
voltage system is shut down. Failure to follow
these steps could result in serious personal injury
or death.
32–01 Suspension Inspection
WARNING
Do not replace individual leaves of a damaged leaf
spring assembly; replace the complete spring
assembly. Visible damage (cracks or breaks) to
one leaf causes hidden damage to other leaves.
Replacement of only the visibly damaged part(s)
is no assurance that the spring is safe. On front
spring assemblies, if cracks or breaks exist in the
two top leaves, a loss of vehicle control could
occur. Failure to replace a damaged spring
assembly could cause an accident resulting in
property damage, serious personal injury, or
death.
Front Suspension Check
Inspect the front spring assemblies for cracked,
broken, or abnormally bent leaves. If any of these
conditions exist, replace the spring assembly; see
Group 32 of the eCascadia
™
Workshop Manual .
Inspect the spring bushings for wear or other
damage. If any of these conditions exist, replace the
damaged bushings.
Front and Rear Suspension
Shock Absorber Check
Make sure the shock absorber brackets are tight,
and the shock absorber is not striking or rubbing the
frame or some other part of the chassis. Striking or
rubbing the frame is characterized by chafe marks on
the shock absorber body and the frame rail; see
Fig.
1 . Check the rubber mounting bushings for cracks,
cuts, swelling, dry rot, or missing pieces. If the shock
absorber bushings are no longer serviceable, replace
the shock absorber with a new one.
Inspect the shock absorber for oil leakage. Some
misting of the oil is normal, and does not mean the
shock is leaking. If the shock absorber is damaged
or leaking, replace it with a new one; see
Group 32
of the eCascadia Workshop Manual .
Freightliner AirLiner Rear
Suspension Check
Components Checking
Inspect the forward spring brackets for wear, cracks,
and other damage. If any of these conditions exist,
replace the damaged bracket(s); see
Group 32 of
the eCascadia Workshop Manual .
Inspect the spring bushings for wear or other
damage. If any of these conditions exist, replace the
damaged bushings.
