Loading; Braking - Ford 2006 F-350 Owner's Manual

Tires, Wheels and Loading
• If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lubricant if not already so
equipped. Refer to Lubricant Specifications in the Maintenance
and specifications chapter for the proper axle lubricant. Remember
that regardless of the rear axle lubricant used, do not tow a trailer for
the first 500 miles (800 km) of a new vehicle, and that the first 500
miles of towing be done at no faster than 70 mph (112 km/h) with no
full-throttle starts.
• When turning make wide turns to allow trailer tires to properly clear
any obstacles.
• Be prepared for trailer sway due to buffeting when larger vehicles
pass in either direction.

Loading

• Keep the center-of-gravity low for best handling.
• Trailer loads should be evenly distributed front to back and left to
right.
• The load distribution within the trailer should be such that 10% – 15%
of the trailer weight is on the hitch. (15% – 25% for 5th-wheel or
gooseneck towing.)
• Never exceed truck, trailer, receiver, ball, tongue, tire or coupler
loading recommendations.

Braking

• The trailer brakes must be inspected and serviced at intervals
specified by the manufacturer. This includes the shoes, drum and
trailer brake magnets.
• Electric brakes also require periodic adjustment to keep the shoes
properly spaced. If the brakes get hot when driving or if they will not
hold, chances are that they need adjustment.
• Anticipate the need to stop; allow much more distance and time to
stop than normal.
• Do not apply the trailer brakes for extended periods of time as they
can overheat and lose effectiveness.
