ESSENTIAL TOWING CHECKS
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mph(80 km/h).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.

as a stroke indicator to aid inadjustment checks. If the push rod isclean and the brakes are out ofadjustment, you can see the orangemarker protruding from the chamberwhen the brakes are applied.
•Checking the brake lining (every serviceinterval). When brake linings or blockswear within 0.063 in (1.6 mm) theymust be replaced.
•Periodic checking (every serviceinterval) of the air compressor filter.Check the filter minder and when theindicator is near or on the red linemarked Service, replace the filter andreset the service filter minder.
Do not back off or disconnect the frontbrakes so that they are less effective,letting the rear brakes do all the stoppingof your vehicle. Do not overlook the brakeson the trailer either. Brake condition on thetrailer is just as important as the tractor.Proper brake balance on trucks andtractor-trailers is essential for effectivebraking.
Once a year, inspect the entire brakesystem:
•Rubber components for deterioration.A qualified technician should inspectthese components and replace themas necessary. Replacement intervalsvary according to the severity andlength of vehicle service.
•Condition of brake drums, brakechambers and slack adjusters.
•System for air leaks.
•Hose or pipes for rust, damage anddeterioration.
•Operation of service and parkingbrakes.
Periodically inspect parts such as air brakechamber diaphragm, air compressor andair cleaner. Replace any parts if you canconsider them unserviceable.
Air Dryer
Climactic conditions affect performanceof desiccant or after-cooler type air dryers.You must establish a maintenanceschedule for each specific operation.
The use of an air dryer on a vehicle doesnot eliminate the need to drain the airreservoirs periodically.
Inspect for moisture in the air system byopening reservoirs, draincocks or valvesand checking for presence of water. Thepresence of small amounts of water dueto condensation is normal and is not anindication that the dryer is not functioningproperly.
Replace or rebuild the desiccant cartridgewhen you determine that the desiccant iscontaminated and does not have adequatewater absorption capacity. The desiccantchange interval may vary. A generalrecommendation is to replace thedesiccant every 12 months (yearly). Ifexperience has shown that extended orshortened life has resulted for a particularinstallation, then the yearly interval can beincreased or decreased accordingly.
Draining the Air Brake Reservoir
WARNING: Failure to drain airbrake reservoirs can result in a reductionor loss of braking ability due to fluidaccumulation in the reservoir and/orpossible freeze-up during cold weather.
Completely drain all the air brake reservoirsdaily by opening the draincock at the endsof the tanks. (Where accessible.Pull-chains are used when the drains areundercab or otherwise inaccessible.) Closethe draincock after draining. Manually drain

AXLE INSPECTION
Front Axle
Maintaining the front axle alignment tospecifications is very important. A qualifiedtechnician should check and maintain thealignment.
Regular inspections should include:
•Toe-in inspection and adjustment (ifnecessary), particularly with radialtires.
•Checking for proper tightness of axlemounting U-bolt nuts, attaching ormounting bolts and nuts.
•Checking the axle for damage, binding,worn parts and adequate lubrication.
•Checking the kingpins for excessivewear. Also, perform this check duringother scheduled maintenance, forexample as tire rotation or service,wheel bearing service and alignment.See the workshop manual for properprocedures.
Toe-in
It is essential to maintain correct toe-inand tire pressure for optimum tire wear.
Inspecting steer axle tires in the first3,000–10,000 mi (5,000–16,000 km)generally shows if tires are wearingnormally.
Rapid outside shoulder wear on both tiresindicates too much toe-in.
Rapid inside shoulder wear on both tiresindicates too much toe-out.
In P&D-type service, there can be aleft-to-right steer tire tread life differentialup to 40% depending on routes and othervariables.
Follow the tire manufacturer'srecommended cold inflation pressure forthe tire size, load range (ply rating) andsteer axle loading typical for their operation(each steer axle tire equals ½ steer axleloading).
Special applications may warrant a settingbased on experience with the type of tireoperating loads and conditions. Radial tiresare more sensitive to toe-in setting thanbias ply tires. Fine tuning school busalignment to line-haul truck standardsdoes not drastically improve tire tread life.
STEERING SYSTEM
INSPECTION
WARNING: Failure to maintain thesteering system in proper condition cancause reduced steering ability resultingin property damage, personal injury ordeath.
Note:Have any steering problemsimmediately corrected by a qualified servicetechnician.
Ask your service technician to examine thesteering mechanism. Only minoradjustments may be necessary.
Regular inspections should include:
•Checking the tie rod, drag link endclamp bolts and ball joints for propertightness.
•Checking for installation and spread ofcotter pins and tightness of nuts atboth ends of the tie rod and drag link.
•Checking that the pitman arm (steeringarm at steering gear) mounting is tightand locked. Check system for leaks orhose chafing. Repair immediately, ifnecessary.

E.16: Indicates the wheel or rimdiameter in inches. If you changeyour wheel size, you have topurchase new tires to match thenew wheel diameter.
Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, check
your tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommendedby Ford Motor Company.
You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Fordrecommends the use of a digitalor dial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns
WARNING: Under-inflationis the most common cause oftire failures and may result insevere tire cracking, treadseparation or blowout, withunexpected loss of vehiclecontrol and increased risk ofinjury. Under-inflation increasessidewall flexing and rollingresistance, resulting in heatbuildup and internal damage tothe tire. It also may result inunnecessary tire stress, irregularwear, loss of vehicle control andaccidents. A tire can lose up tohalf of its air pressure and notappear to be flat!
Always inflate your tires to theFord recommended inflationpressure even if it is less than themaximum inflation pressureinformation found on the tire. TheFord recommended tire inflationpressure is found on the SafetyCompliance Certification Label orTire Label. Failure to follow the tirepressure recommendations cancause uneven treadwear patternsand adversely affect the way yourvehicle handles.

Note:Some spare tires operate ata higher inflation pressure than theother tires. For T type mini-sparetires, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat 60 psi (412 kPa). For full-sizeand dissimilar spare tires, see theDissimilar spare wheel and tireassembly information for adescription. Store and maintain atthe higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6.Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tireand cause an air leak.
7.Check the sidewalls to makesure there are no gouges, cutsor bulges.
Checking Pressure when tiresare hot:
If pressures are checked after tireshave been driven for more thanthree minutes or more than 1 mile,(2 km) the tires become hot andthe pressures will increase byapproximately 4 psi (27.6 kPa).Therefore when the tire pressureis adjusted under these conditions,it should be increased to a gaugereading of 4 psi (27.6 kPa) greaterthan the recommended coldinflation pressure.
For Example Only
33 psi (230kPa)Gauge readingof hot tire
32 psi (220kPa)If recom-mended, coldinflation pres-sure is
The hot tire pressure is only 1 psi(10 kPa) greater than therecommended cold inflationpressure. Therefore, add 3 psi(20 kPa) more to increase thehot pressure to 4 psi (30 kPa)over the recommended coldinflation pressure.
36 psi (250kPa)New hot pres-sure
Tire Inflation Information
WARNING: An inflated tireand rim can be very dangerousif improperly used, serviced ormaintained. To reduce the riskof serious injury, never attemptto re-inflate a tire which hasbeen run flat or seriouslyunder-inflated without firstremoving the tire from the wheelassembly for inspection. Do notattempt to add air to tires orreplace tires or wheels withoutfirst taking precautions toprotect persons and property.
