Wheel Bearing Adjustment
For reliable operation and adequate service
life, the wheel bearings must be properly
adjusted and checked during the service pe-
riod. Loose wheel bearings could cause
premature tire wear and possibly affect ve-
hicle handling. See your Volvo Truck
dealer for proper servicing.
Watch carefully for oil leaks and listen for
unusual noises. These are indications of
worn bearings, bad seals or misadjusted
bearings. These are problems which must
be corrected as soon as possible.
Failure to keep wheel bearings properly
adjusted may result in accelerated tire
wear, poor handling and wheel separa-
tion from the vehicle.
Failure to properly maintain bearings
can ultimately result in loss of wheel
and vehicle control, and cause serious
personal injury or death.
