Other Maintenance Items - GMC 1999 Sierra 1500 Pickup Owner's Manual

Other Maintenance Items
Front Suspension and Steering Linkage
Your maintenance schedule will tell you how often to lubricate the fittings. See
"Recommended Fluids and Lubricants'' in the Index for the proper lubricant to
use.
Front Wheel Bearings
Your vehicle has front wheel bearings that must be cleaned and repacked.
Your maintenance schedule will tell you how often this must be done.
Front Shock Absorbers
The front shock absorbers of your vehicle do many things. They help the
vehicle ride smoothly and also control the travel of the suspension system.
When the shock absorbers are serviced, any replacement shock absorbers
must be the same as the original equipment shock absorbers in both
extended length and strength.

me same as
the original shock
I
absorbers, the shock absorbers or suspension system could be damaged.
Wheel Nut Torque
For vehicles with dual wheels, when the vehicle, wheel or fasteners are new,
have the torque set at the first 100, 1,000 and 6,000 miles (160, 1600 and
9600 km). Use the torque specified in the appropriate Specification Chart later
in this section.
Single Belt Accessory Drive
If your new vehicle uses a serpentine belt, it is lighter, and more durable
than systems with several belts.
The belt runs over or around the pulleys on the engine. A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier. If you need to replace the belt, be sure to get the correct
replacement belt. Your dealership or parts supplier can help you with this.
The Accessory Drive Belt Routing label on your vehicle will show you how to
route the belt your vehicle uses.
