2008 FORD F650 torque

Air suspension U-bolt checks and re-torquing procedures
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean
the threads if contaminated.
2. Using a torque wrench, determine if any nuts can be turned with a
force below the specified torque.
3. Using the lowest discovered torqued nut as a starting point, retighten
the nuts using the sequence listed underAir suspension U-bolt and
U-bolt nut installation.
Air suspension U-bolt and U-bolt nut installation
1. Inspect the threads of the U-bolt and nut for rust and debris. Clean
the threads if contaminated.
2. Install the U-bolts and nuts and torque the nuts to 15 ft. lb. (20 N•m),
using a diagonal pattern.
3. Re-torque the nuts to 100 ft. lb. (136 N•m), using a diagonal pattern.
4. Re-torque the nuts to 200 ft. lb. (271 N•m), using a diagonal pattern.
5. Re-torque the nuts to 400 ft. lb. (542 N•m), using a diagonal pattern.
(For vehicles equipped with 14ACC, 14 ADN and 14ADP axles, do not
use Step 6.)
6. Re-torque the nuts to 425 ft. lb (576 N•m), using a diagonal pattern.
(For vehicles equipped with 14ACC, 14 ADN and 14ADP axles.)
7. Use the same diagonal pattern with each U-bolt nut re-torque.
Spring U-bolt checks
Check U-bolt nuts and re-torque every 36,000 miles (58,000 km) after
initial 1,000 miles (1,600 km) re-torque. The U-bolt and nut threads and
seats should be cleaned and lubricated to ensure peak condition when
re-torqued.
DRIVESHAFT
At the regular lubrication interval, check the universal joints for any
evidence of wear or looseness. Should driveshaft vibrations occur, stop
the vehicle immediately to avoid possible hazardous consequences or
damage to other components.
REAR AXLE LUBRICANT
Refer to theScheduled Maintenance Guidechapter for rear axle
lubricant level checks and lubricant change intervals.

When installing wheel balance weights, they must be mounted on the
dome-side of the wheel only. Failure to do so may result in loss of wheel
weight and/or damage to brakes or wheels.
Important:Remember to replace the wheel air valves when the road
tires are replaced at the end of their useful life.
Oil lubricated front wheel bearings
During normal vehicle duty cycle, the lube and air inside the hub/wheel
cavity expands and if not vented, causes pressure build-up that could
cause accelerated seal wear.
There are two venting methods:
•a slit or small hole in the rubber check vent or
•the window
You can use either of these methods to prevent pressure build-up.
Normal maintenance
Over a period of time, if not routinely cleaned, a slight film of oil can
collect dirt around the rubber fill plug and face, which could appear to
be a leak. Routine cleaning ensures that the lube level can be easily
observed through the clear window as intended. In situations where the
window is clean on the outside but discolored on the inside, the lube
level may be checked by inserting a finger through the rubber check
vent hole.
The specified lube level for a clear window type hubcaps is from the
minimum line to + 5/16 inch above the minimum line.
If the lube level should suddenly drop dramatically below the minimum
level, see theWorkshop Manualfor diagnostic procedure.
Installation, tightening and alignment
When installing wheels, be certain that the threads on studs and nuts are
clean to permit correct torque. The mounting surfaces of rims, wheels,
spacer rings and clamps must be free of dirt, rust, lubricants or damage.
Use a wire brush to clean the mounting contact surfaces. Do not use
lubricant on threads.
After the rim or wheel has been properly tightened, it should be checked
for alignment. Rotate the wheel with a piece of chalk attached to a
steady, firm surface, and placed to just barely clear the outside surface of
the tire bead seat. This procedure will point out the high spot. A high
spot does not necessarily mean that the lug nuts have been unevenly
tightened. This condition or misalignment could be caused by a bent
wheel.

Wheel tightening sequence:
8–lug wheel
10–lug wheel
5. Continue tightening the nuts to the torque specifications in the torque
chart using the same crisscross sequence shown.
6. After operating the vehicle approximately 50 miles (80 km), check the
nuts for tightness. Some natural seating of parts may be encountered
and the torque on the nuts will drop. Retighten all nuts to specifications.
Once a week, inspect and retighten the wheel stud nuts.
Note:When installing the tire and rim assembly on disc-brake equipped
axles, make sure the tire valve stem clears the brake caliper. The use of
a tire manufacturer’s stem forming tool is the only acceptable method of
obtaining clearance when necessary.
Proper torque
It is important to tighten and maintain wheel and rim mounting nuts to
the proper torque. Loose nuts or over-tightened nuts can lead to
premature wear and possible failure of the wheel and/or mounting
hardware.
Changing wheel types
Consult your dealer or wheel/rim distributor before attempting any wheel
or fastener changes.

Use only the same type and style wheels and mounting hardware
to replace original parts. Failure to do so may result in an
assembly that looks fine, but does not fit together properly. This could
possibly cause wheel or fastener failures which could result in property
damage, personal injury or death.
Note:Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note:Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange-nut mounting systems, changing the hub and stud assembly.

Note:Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:
•Hex nut and rim clamp contact surfaces.
•Cap nut ball face and ball seat on the disc wheel.
•Flange nut washer surface and flat on the disc wheel.
TIRE INFORMATION
Inflation
Always maintain your tires in good condition. Frequently check
and maintain correct inflation pressures as specified by tire
manufacturers. Inspect periodically for abnormal wear patterns and
repair/replace cut or broken tire casing. Always use experienced,
trained personnel with proper equipment and correct procedures to
mount or remove tires and wheels. Failure to adhere to these warnings
could result in wheel or tire malfunction, damage to your vehicle,
personal injury, or death.

remanufactured parts are used for maintenance replacements (or for the
service) of components effecting the emission control, the owner should
be ensured that such parts are warranted by their manufacturer to be
equivalent to genuine Ford Motor Company Parts in performance and
durability. Please consult your warranty information booklet for complete
warranty information.
Authorized dealer maintenance
Your authorized dealer specializes in knowing all about Ford Motor
Company vehicles rather than knowing a little about all makes.
There are Ford or Ford of Canada dealer service shops ready to serve
you wherever you drive in the U.S. or Canada. They stock Ford and
Motorcraft parts, and Ford Chemicals and lubricants. You can be
confident that these meet the same exacting design and quality
standards as those used to build the vehicle originally. Dealer Service
Technicians have available training in the latest product developments
and service techniques.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic of
the chemical compound and in itself does not demonstrate that a fluid
needs to be changed. Oils and fluids identified in theScheduled
Maintenance Guidechapter should be changed at the specified interval
or in conjunction with a repair. Flushing is a viable way to change fluid
for many vehicle sub-systems during scheduled maintenance and should
only be done using the same fluid required to finish the maintenance
procedure, or a Ford approved flushing chemical.
OWNER MAINTENANCE
You can do much of the maintenance your vehicle requires yourself, if
you have the time and a reasonable amount of mechanical ability. If you
prefer to have this work done professionally, your authorized dealer
stands ready to help you.
All mechanical components and attachments are important in that they
could affect the performance of vital components and systems. If
replacement becomes necessary, they must be replaced with parts having
the same part number or with equivalent parts. Torque values of the
attaching parts must be used as specified during any reassembly
procedure to ensure proper retention.
