Chassis Lubrication
DANGER
Before working on or servicing a
vehicle, set the parking brakes, place the
transmission in neutral and block the
wheels. Failure to do so can result in
unexpected vehicle movement and can
cause serious personal injury or death.
General lubrication includes lubricating all
the grease fittings in the drivetrain, front and
rear suspensions, power steering, and front
axle, using a grease gun.
Grease the chassis every 15,000 miles
(24,000 km). However, if the vehicle is
in a demanding application or running
in a dirty or corrosive atmosphere,
adjust the lubrication intervals to reflect
heavy-duty use. For example, if driven
in heavy stop-and-go traffic with a lot of
maneuvering, the lubrication intervals should
be every 10,000 miles (16,000 km) or less.
All lubricating points are found on the
chassis lubrication chart on the next page.
Lubricating Grease
Use grease with a lithium base with EP
additives and a consistency of NLGI No. 2.
The No. 2 consistency is suitable for most
temperatures. Use NLGI No. 1 or No. 0 for
extremely low temperatures.
Care should be taken not to use any grease
other than one with EP additives for the
driveshaft. DO NOT use any solid lubricants,
such as graphite, copper or molybdenum
disulfide.
Lubrication Procedure
Make sure the grease fittings are cleaned
off before filling grease. Dirt on the fitting
that is not cleaned off is pushed into the part
together with the new grease. Always fill
grease to the point where old grease and
contaminants are forced out from the part and
only new grease comes out. If new grease
cannot be filled so old grease is flushed out,
the part needs to be checked for problems. If
a fitting does not accept lubrication due to
damage or internal stoppage, replace it with
a new fitting.
Note: Think of greasing the same way as an
oil change. A
ll old grease should come out
and be replaced with new grease.
Where rubber or plastic parts are involved,
do not heat part for better grease application.
Remove excess grease from fittings, shackles
and other surfaces.
Note: Always grease a Volvo front axle with
the wheels on the ground.
