2021 FORD TRANSIT suspension

Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty and durable load
carrying capability. For this reason, we
strongly recommend that you do not make
modifications such as adding or removing
parts (such as lowering kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
Any modifications to a vehicle that raise
the center of gravity can make it more likely
the vehicle will rollover as a result of a loss
of control. We strongly recommend that
caution be used with any vehicle equipped
with a high load or device (such as ladder
or luggage racks).
Failure to maintain your vehicle properly
could void the warranty, increase your
repair cost, reduce vehicle performance
and operational capabilities and adversely
affect driver and passenger safety.
Frequent inspection of vehicle chassis
components is recommended if the vehicle
is subjected to off-highway usage.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It's always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator's ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If the stability control or traction control
system detects a fault, the following may
occur:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If the stability control or traction control
system activates, the following may occur:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake pedal, the
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle.
Electronic Stability Control
The system helps to prevent your vehicle
skidding or laterally sliding by individually
applying the brakes to one or more wheels
and, if necessary, reducing engine power.
Roll Stability Control
The system helps to prevent rollovers by
detecting your vehicle's roll motion, and
individually applying the brakes to one or
more wheels.

STEERING
Electric Power Steering WARNING:
The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
• Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Note: See
Recommended
Towing Weights (page 235).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 263).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
229).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

WARNING: Do not spin the
wheels at over 34 mph
(55 km/h). The tires may fail and
injure a passenger or bystander.
Driving habits have a great deal to
do with your tire mileage and
safety:
• Observe posted speed limits.
• Avoid fast starts, stops and
turns.
• Avoid potholes and objects on
the road.
• Do not run over curbs or hit the
tire against a curb when
parking.
Highway Hazards
No matter how carefully you drive
there is always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect a tire or your vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and replace it with the spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
the tires. If your vehicle seems to
pull to one side when you are
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.
Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of the tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.

Rear-wheel drive and
four-wheel drive vehicles with
dual rear wheels.
USING WINTER TIRES
WARNING: Snow tires must be the
same size, load index and speed rating
as those originally provided by Ford. Use
of any tire or wheel not recommended
by Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of
control, vehicle rollover, personal injury
and death. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure. Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label on the B-Pillar or the edge of the
driver door. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles.
WARNING: If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load
range as the original tires listed on the
tire placard, and they must be installed
on all four wheels. Mixing tires of
different size or construction on your
vehicle can adversely affect your
vehicle's handling and braking, and may
lead to loss of vehicle control.
Your vehicle has all-season tires that are
optimized for use in all weather conditions.
As the seasons change you may choose to
use winter tires or snow tires. Winter tires
and snow tires are available to purchase
from an authorized dealer.
We recommend that you use winter tires
when the temperature is
45°F (7°C) or
lower, or in snow and ice conditions.
If you use winter tires or snow tires, inflate
them to the recommended tire pressures
listed on the tire information label. The
label is on the driver side B-pillar.
