Electronic Stability Control (ESC) and
is modified (e.g. adding or removing
an axle, converting from a truck to a
tractor, converting from a tractor to a
truck, changing the body, lengthening
of the wheelbase and/or frame, relo-
cating frame components, or modifying

Driveline
See the driveshaft manufacturer's
operator's manual for lubrication
specifications and service intervals.
WARNING
Improper lubrication of U-joints can
cause them to fail prematurely. The
driveshaft could separate from the ve-
hicle and result in an accident. Make
sure lubricant is purged at all four ends
of each U-joint and loosen caps if nec-
essary. Also, regularly inspect U-joints
for excessive wear or movement, and
repair or replace as necessary. Failure
to comply may result in death, person-
al injury, equipment or property dam-
age.
Tires
Your tires are a very important part of your
vehicle’s whole braking system. How fast
you can stop depends mostly on how much
friction you get between the road and your
tires. In addition, keeping your tires in good
condition is essential to the safe, efficient
operation of your vehicle. Regular, frequent
inspection and the right care will give you
the assurance of safe and reliable tire
