steering FORD F450 SUPER DUTY 2017 Service Manual

If the power steering system breaks down(or if the engine is turned off), you cansteer the vehicle manually, but it takesmore effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
If any steering components are serviced orreplaced, install new fasteners (many arecoated with thread adhesive or haveprevailing torque features which may notbe re-used). Never re-use a bolt or nut.Torque fasteners to specifications.
A high crown in the road or high crosswindsmay also make the steering seem towander or pull.
Adaptive Steering (If Equipped)
WARNING
The adaptive steering system hasdiagnostic checks that continuouslymonitor the system. If a fault isdetected a message displays in theinformation display. Stop your vehicle assoon as it is safe to do so. This warningmessage may clear if the fault is no longerpresent. If an adaptive steering systemwarning message appears each time youstart your vehicle, have the systemchecked as soon as possible.
The adaptive steering system continuallychanges the steering ratio with changes tovehicle speed, optimizing the steeringresponse in all conditions. The system alsochanges when you switch on thetransmission tow/haul feature. When youselect the tow/haul button, the adaptivesteering system reduces vehicle sensitivityto steering inputs at higher vehicle speeds,while maintaining the ease of parking andmaneuverability at low speeds.
Note:The adaptive steering system isdesigned with a locking device. With thelock engaged, the adaptive steering systemremains mechanically locked at a fixedsteering ratio. You may also notice a clickwhen you switch the vehicle on or after youswitch it off, as the lock disengages orengages.
Note:If your vehicle loses electrical poweror detects a fault when you are driving, thesystem automatically shuts down and youretain normal steering function with a fixedsteering ratio. During this time it is possiblethat the steering wheel may not be straightwhen the vehicle is driving straight ahead.In addition, the driver may notice that thesteering wheel angle required to steer thevehicle may be different.
Note:During parking maneuvers, theadaptive steering system balances the driverwork load for various steering wheel inputsand vehicle loading conditions. Underextreme operating conditions the systemlocking device may engage. This strategyprevents overheating and permanentdamage to the adaptive steering system.Typical steering and driving maneuversallow the system to cool and return tonormal operation.

System Limitations
WARNING
The collision warning system’s brakesupport only reduces collision speedif you first apply your brakes. Youmust brake as you would in any typicalbraking situation.
Due to the nature of radar technology,there may be certain instances wherevehicles do not provide a collision warning.These include:
•Stationary vehicles or vehicles movingbelow 6 mph (10 km/h).
•Pedestrians or objects in the roadway.
•Oncoming vehicles in the same lane.
•Severe weather conditions (seeblocked sensor section).
•Debris build-up on the grille near theheadlamps (see blocked sensorsection).
•Small distance to vehicle ahead.
•Large steering wheel and pedalmovements (very active driving style).
Damage to the front end of your vehiclemay alter the radar sensor's coverage area.This may result in missed or false collisionwarnings. Have an authorized dealer checkyour radar sensor for proper coverage andoperation.

Measurement D has reached maximum orminimum value:
•Make sure that the measurement beingmade is the horizontal distance onlyfrom tailgate to the center of the singleaxle or the center of all the axles on thetrailer. See step 4 of the setup foradditional measurement instructions.The TBA system does not supporttrailer lengths outside the rangeallowed by the information display.
System is circling something beside thesticker or system cannot find the sticker:
•Make sure the rear camera is clean andthe sticker is clearly visible in thecamera image. Clean the camera andsticker if necessary.
•The camera system uses the enteredmeasurements to help locate thesticker. Inaccurate stickermeasurements will degrade thesystem’s ability to locate the sticker.Verify the measurements entered intothe system are accurate.
•Remove the incorrectly circled label ordecal if possible.
•If you cannot resolve the issue a newsticker location should be tried. Thesticker location must still meet therequirements noted in step 3 of thesetup instructions. Only one sticker canbe placed on the trailer for correctsystem function. The previous stickermust be removed or covered so onlyone sticker is visible to the camera.
Calibration
The system monitors various vehicleparameters to ensure your vehicle is beingdriven straight and the trailer straightbehind your vehicle. Any steering input ortrailer movement will pause the calibration.
For best results:
•Use a long, straight and smooth roadwhen attempting to calibrate.
•Drive straight forward.
•Drive between 4 mph (6 km/h) and24 mph (39 km/h).
System Operation
The following warnings or difficulties mayoccur during feature operation. Tips toresolve them are listed below.

Hitches
Note:On pick-up trucks, the trailer hitchprovided on this vehicle enhances crashprotection for the fuel system. Do notremove!
Note:Do not cut, drill, weld or modify trailerhitches. Modifying trailer hitches can reducehitch rating.
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% for conventional towing or15-25% for fifth wheel towing of the totalweight of the trailer is on the tongue.
Hitch components (If Equipped)
The following components will be includedin certain vehicles.
•A 5/8 inch hitch pin rated to tow up to21,000 lbs.
•A 3 inch drawbar.
•A hitch pin sleeve to be used whenmounting the 3 inch drawbar.
•A clevis pin to help keep the hitch pinin place.
Weight-distributing Hitches
WARNING
Do not adjust the spring bars so thatyour vehicle's rear bumper is higherthan before attaching the trailer.Doing so will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Park the loaded vehicle, without thetrailer, on a level surface.
2. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
3.Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
5. Install and adjust the tension in theweight-distributing bars so that theheight of your vehicle's front wheelopening on the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 2-6.

Towing

When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position P to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdaptive Steering and you haveenabled Tow/Haul, the AdaptiveSteering system adjusts the steeringresponse to match your vehicle’s load.The system reduces vehicle sensitivityto steering inputs at higher vehiclespeeds while it maintains the ease ofparking and maneuverability at lowspeeds.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it).
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission inposition P.
4. Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Your vehicle may be equipped with atemporary or conventional spare tire. A"temporary" spare tire is different in size(diameter or width), tread-type(All-Season or All Terrain) or is from adifferent manufacturer than the road tireson your vehicle. Consult information on thetire label or Safety Compliance label forlimitations when using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter you remove the trailer from the water.

Towing

When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytimethe rear axle has been submerged in water.Water may have contaminated the rearaxle lubricant, which is not normallychecked or changed unless a leak issuspected or other axle repair is required.
