156 Maintenance
Spring Bushings
Before working on or inspecting a vehi-
cle, set the parking brakes, place the
transmission in neutral and block the
wheels. Failure to do so can result in un-
expected vehicle movement and can
cause serious personal injury or death.
When lubricating the springs, lift the axle
off of the floor, suspend the frame with
axle stands and lower the axle. The spring
bushings are now in the position where
grease can be added to the contact surfaces.
If the spring bushings are greased without
taking the load off, high wear and lower
lifetime will occur because of no grease
reaching the contact surfaces.
If the vehicle is being driven in severe cli-
mates with a lot of wet, slushy, highly
dusty roads, or in off-road service, increase
the frequency of spring bushing lubrication.

T-Ride Equalizer Beams
The Volvo T-Ride suspension has equalizer
beams between the tandem axles. The beam
bushing needs to be lubricated at the normal
lube intervals for normal highway driving.
If the vehicle is being driven in severe cli-
mates with a lot of wet, slushy, highly
dusty roads, or in off-road service, increase
the frequency of lubrication. If driving in
severe duty, where water may enter the
bushing, daily lubrication may be necessary.
