If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components.
AIR SUSPENSION (IF EQUIPPED)
Note:Do not operate your vehicle without air in the suspension springs.
Operating your vehicle without air in the suspension springs damages the
suspension, degrades ride performance and may cause property damage.
The air suspension system automatically adjusts to different loads to
maintain a constant frame height, allows for ease of vehicle loading,
provides improved vehicle ride, and increased driver comfort.
Air Suspension Dump Switch
Note:The suspension dumps air when the ignition is in the accessory or
on position, but fills only when the ignition is in the on position.
A switch located in the overhead
switch pack controls the system. It
operates only when the ignition is in
the accessory or on position and the
air tanks have sufficient pressure to
fill the air springs. When you turn
off the ignition, the suspension
remains in whatever state it was last
set.
Pressing the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so your vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when using the
switch to release air pressure in the rear air shocks. Never
drive your vehicle when the warning lamp is illuminated and
there is low (or no) air pressure in the shocks.

Perform a complete inspection of the air induction system annually.
In areas where road salt is used, disassemble the joints of each aluminum
component and inspect for salt build-up and presence of chlorine that
can cause aluminum particles to flake off and enter the engine
combustion chambers. If evidence of corrosion is found (usually at the
pipe connections), use a wire brush to clean the inside of the pipes and
inside the rubber hoses.
If pitting is evident at the joint ends of the intake pipes, use Motorcraft
Silicone Gasket and Sealant TA-30 to seal the joints. Make sure no
excess material, which can pull into the engine, is on the inside of the
pipes. If the service condition of the pipes, hoses or clamps is
questionable, replace the defective part(s).
Make sure to clean all dust and debris out of the pipes and couplings
with a clean, damp rag before reassembly.
Chassis-mounted Charge Air Cooler
Visually inspect the core assembly for debris and clogging of external fins
with the engine off. Before engine operation, remove any debris blocking
the core.
•Turbocharger-to-charge air cooler
•Charge air cooler-to-intake manifold pipe
•Mounting bracket
•Chassis-mounted charge air cooler core
Inspect air intake piping:
•Check for accumulation of salt deposits (where applicable). If
present, disassemble and clean the complete air intake piping system.
If pitting is evident on the intake piping, use Motorcraft Silicone
Gasket and Sealant TA-30 to seal joints against leakage.
•Check for loose hoses and clamps.
•Check for ruptured or collapsed hoses.
•Check air cleaner housing for cracks.
Suspension Inspection
Note:Do not adjust air suspension height to any setting other than the
specified setting. Altering the height setting changes the driveline angle
and may result in unwarrantable component damage, such as
transmission component damage.
Verify drive axle air suspension height and height control valve
performance at engine oil change intervals.
