It is recommended that the front wheel bearings be cleaned, inspected and repacked every 30,000 miles
(48,000km) and as soon as possible if the front hubs have been submerged in water.
Sodium based grease is not compatible with lithium based grease. Be careful not to mix the two types.
The best way to prevent this is to completely clean all of the old grease from the hub assembly before
installing any new grease.
Before handling the bearings there are a few things that you should remember to do and try...

Pack the inside of the hub with wheel bearing grease. Add grease to the hub until the grease is flush
with the inside diameter of the bearing cup.
6. 
Thoroughly pack the bearing with fresh, high temperature wheel-bearing grease before installation
Pack the bearing assembly with wheel bearing grease. A bearing packer is desirable for this operation.
If a packer is not available, place a large portion of grease into the palm of your hand and sliding the
edge of the roller cage through the grease with your...

Carefully position the hub and rotor assembly onto the spindle. Be careful not to damage the grease
seal.
9. 
Place the outer bearing into position on the spindle and into the bearing cup. Install the adjusting nut

TOWING THE VEHICLE
General Recommendations
Your vehicle was primarily designed to carry passengers and cargo. It is important to remember that towing a
trailer will place additional loads on your vehicles engine, drivetrain, steering, braking and other systems.
However, if you decide to tow a trailer, using the prior equipment is a must.
Local laws may require specific equipment such as trailer brakes or fender mounted mirrors. Check your local
laws.
Trailer Weight

and are for use with fifth wheel trucks, only.
When youve determined the hitch that youll need, follow the manufacturers installation instructions, exactly,
especially when it comes to fastener torques. The hitch will subjected to a lot of stress and good hitches come
with hardened bolts. Never substitute an inferior bolt for a hardened bolt.
Oil Cooler
Aftermarket engine oil coolers are helpful for prolonging engine oil life and reducing overall engine
temperatures. Both of these factors increase...

Your truck can be towed forward with the driveshaft connected as long as you do not exceed 35 miles in
distance and 50 MPH in speed. Severe damage to the transmission can occur if these limits are exceeded. If
your truck has to be towed backward and is a 4WD model, unlock the front axle driving hubs, to prevent the
front differential from rotating and place the transfer case in Neutral. Also clamp the steering wheel on all
models in the straight ahead position, with a clamping device designed for towing...

JUMP STARTING A DEAD BATTERY
Introduction
Whenever a vehicle is jump started, precautions must be followed in order to prevent the possibility of
personal injury. Remember that batteries contain a small amount of explosive hydrogen gas which is a
by-product of battery charging. Sparks should always be avoided when working around batteries, especially
when attaching jumper cables. To minimize the possibility of accidental sparks, follow the procedure
carefully.
Connect the jumper cables to the batteries...

Do not smoke or allow sparks anywhere near the batteries.
· 
In cold weather, make sure the battery electrolyte is not frozen. This can occur more readily in a
battery that has been in a state of discharge.
· 
Do not allow electrolyte to contact your skin or clothing.
· 
Jump Starting Procedure Make sure that the voltages of the 2 batteries are the same. Most batteries and charging systems are of
the 12 volt variety.
1. 
Pull the jumping vehicle (with the good battery) into a position so the jumper...
