[GF03350(F )03/96]
If pull occurs during the first 500 miles
(800 km), make 10 moderately fast stops from
40 mph (65 km/h) and then perform the
self-adjustment procedure above. It may be
necessary to repeat this operation to properly
seat new brake linings and pads.

Stopping Distances
*
[GF03450(FM)01/96]
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.
%*
[GF03500(FM)01/96]
Applying the Brakes
*
[GF03550(FM)01/96]
Apply the brake pedal gradually. Use the
ªsqueezeº technique Ð push on the brake pedal
with a steadily increasing force. This allows the
wheels to continue to roll while you are slowing
down, which lets you steer properly.
*
[GF03600(FM)01/96]
Do not drive with your foot resting on the brake
pedal. This will increase your vehicle's stopping
distance and may also cause brake damage.

[GF19650(F )01/96]
Drive cautiously to avoid vehicle damage from
concealed objects such as rocks and stumps.
Know the terrain or examine maps of the area in
question before driving. Map out your route
beforehand. To maintain steering and braking
control of your vehicle, you must have all four
tires on the ground, and they must be rolling,
not sliding or spinning.
[GF19700(F )04/96]
Transmission upshift in 4x4 with transfer case in
4L may be quite firm due to large total gear
reduction. This condition is normal.
*
[GF19750(F )01/96]
Sand
*
[GF19800(F )01/96]
When driving over sand, try to keep all four
wheels of the vehicle on the most solid area of
the trail. Do not reduce the tire pressures but
shift to a lower gear and drive steadily through
the terrain. Apply accelerator slowly and avoid
spinning the wheels.
*
[GF19850(F )01/96]
Mud and Water
*
[GF19900(F )01/96]
When driving through water, determine the
depth; avoid water higher than the bottom of
the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
*
[GF19950(F )01/96]
Once through water, always try the brakes. Wet
brakes do not stop the vehicle as effectively as
dry brakes. Drying can be improved by moving
your vehicle slowly, while applying light
pressure on the brake pedal.
*
[GF20000(F )01/96]
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance which could damage drive
components.
*
[GF20050(F )03/96]
NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.

Vehicle Loading/Towing
Information
*
[GF20825(F )01/96]
Your vehicle's load capacity is designated by
weight, not volume, so you cannot necessarily
use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire,
rim sizes and inflation pressures are specified for
your vehicle at the assembly plant on the Safety
Compliance Certification Label. The Certification
Label is located on the left front door lock facing
or the door latch post pillar.

Gross Vehicle Weight Rating (GVWR)
*
[GF21030(FM)01/96]
To avoid overloading a vehicle, the owner
should observe the manufacturer's specified
Gross Vehicle Weight Rating. The GVWR is the
maximum total weight of base vehicle,
passengers, optional components and cargo that
a particular vehicle was designed to carry.
%*
[GF21040(FM)01/96]
Gross Axle Weight Rating (GAWR)
*
[GF21050(FM)01/96]
We have all seen a car or a truck that is loaded
down in the rear and riding high in the front.
This is a dangerous condition that usually means
that the rear suspension components are under
severe strain and that vehicle handling is
impaired. There is more to carrying a load than
just payload or GVWR.
*
[GF21060(FM)01/96]
Your Safety Compliance Certification Label not
only gives the GVWR, it also gives the Gross
Axle Weight Rating (GAWR) which is the
carrying capacity for each axle system. For
trucks, the rear axle will be designed to carry
more weight than the front.
*
[GF21070(FM)01/96]
The rating is based on the carrying capacity of
thelowest ratedaxle and suspension component
as well as other factors. This is why it's so
important to observe vehicle loading ratings.
Overloading a vehicle punishes components and
can lead to shortened service life or outright
failure.
*
[GF21080(FM)01/96]
The capacity of the tires is included as part of
the axle and suspension system, which is to be
considered when determining the lowest rated
component. Tires are rated to carry a specific
maximum load at a specific maximum tire
pressure.

[GF21090(FM)01/96]
Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[GF21100(F )01/96]
The vehicle must not be loaded to both the front
and rear GAWR because the GVWR will be
exceeded. The GAWR of the front and rear axles
exceeds the GVWR when added together to
allow flexibility in fore and aft loading of cargo.
*
[GF21110(FM)03/96]
With the tires inflated to the specified pressure,
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[GF21120(FM)01/96]
GCWR (Gross Combined Weight Rating)
*
[GF21130(FM)01/96]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[GF21140(FM)01/96]
Maximum Trailer Weight Rating
*
[GF21150(FM)01/96]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It is specified by the
manufacturer and is determined by subtracting
the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight
of the driver from the GCWR for the towing
vehicle.

bolt. If necessary, use the tapered end of the
wrench inserted in the retainer for more
leverage.

spare tire during removal or installation.
[ER08200(F )04/96]
To stow the spare tire:
[ER08300(F )04/96]
1. Position the spare tire so it is balanced on
the channel assembly.
[ER08400(F )04/96]
2. Screw the retainer on the center bolt and
tighten until the wheel is secured to the
channel.
[ER08500(F )04/96]
3. Put the tapered end of the lug nut wrench
into the channel assembly tube and lift and
line up the channel and eyebolt, so the
shoulder of the eyebolt is pushed all the way
into the slot.
[ER08600(F )04/96]
4. Tighten the eyebolt with the tapered end of
the wrench until the spare tire cannot be
moved by hand pressure. Adjustment of the
driver side channel ball end bolt is not
required when stowing an original
equipment size wheel and tire.
[ER08700(F )04/96]
Position of eyebolt
[ER08800(F )04/96]
After the eyebolt has been tightened it should be
at a right angle to the slot. That is, it should be
at 90 degrees to the center line of slot, if not,
tighten it to that position. This is necessary to
prevent channel separation and/or loss of the
spare tire if the spare becomes loose in the
channel.

Replacing the Tires
*
[MC26900(FM)01/96]
Replace any tires that show wear bands. When
your tire shows a wear band, it has only 1/16
inch (2 mm) of tread left.

Wear band
*
[MC27000(FM)02/96]
Because your vehicle's tires may wear unevenly,
you may need to replace them before a wear
band appears across the entire tread.
*
[MC27100(FM)01/96]
RWARNING
When replacing full size tires, never mix
radial, bias-belted, or bias-type tires. Use
only the tire sizes that are listed on the
tire pressure decal. Make sure that all tires
are the same size, speed rating, and
load-carrying capacity. Use only the tire
combinations recommended on the decal.
If you do not follow these precautions,
your vehicle may not drive properly and
safely.

316 [MC52510(F )04/96]Cleaning F-350 Aluminum Dual Rear Wheels
[MC52520(F )04/96]
If you have factory-installed Forged Aluminum
Wheels on your F-350, you may use the cleaning
instructions below to help provide optimum
appearance season after season.
[MC52530(F )04/96]
1. Keep your F-350 Forged Aluminum Wheels
looking great with simple care. Wash the
wheels with steam or high pressure water
from a hose, and a mild detergent, such as
Ford's Premium Car Wash Concentrate, or
equivalent. Do not use harsh alkaline
cleaners.
[MC52540(F )04/96]
2. You can brighten the wheels, even after
years of use, with readily-available buffing
compounds, such as Ford Custom Bright
Metal Cleaner or equivalent. Follow the
buffing instructions that come with the
compound.
[MC52550(F )04/96]
3. When tires are removed, the entire wheel
must be cleaned and inspected. Remove any
soil or oxidation products from the tire side
of the rim with a wire brush.
[MC52560(F )04/96]
4. Aluminum alloys resist corrosion. This is
why your Forged F-350 Aluminum Wheels
never need sanding or painting. However,
certain environments can lead to corrosion:
salt, chloride compounds used for snow
removal and highly alkaline materials. Wash
corrosives elements off the wheel before they
have time to react.
