Guidelines for Working on the Volvo T-Ride Suspension
You must read and understand the precautions and
guidelines in Service Information, Group 60, "General
Safety Practices, Wheel Suspension and Steering"
before performing this procedure. If you are not
properly trained and certified in this procedure, ask
your supervisor for training before you perform it.
To ensure personal safety and to help avoid accidental
damage to suspension components, always follow these
guidelines any time work is performed on the suspension.
1
Always park the vehicle on a level surface, chock the front
wheels and release the parking brakes.
2
When lifting the chassis to perform any procedure,
always support the chassis with adequate jack stands
before beginning work on the suspension.
3
For easier removal or installation of T-Ride Suspension
components it may be necessary to remove the fifth wheel
to adequately perform service procedures. Refer to the
appropriate service literature for removing the fifth wheel.
4
To ensure that the U-bolts and Torque Rods holding the
rear suspension to the drive axle retain their clamp load,
observe the following practices:
Anytime you work on the suspension, make sure you
loosen both sides of the suspension on an axle at
the same time.
Note: It is difficult to realign all parts with opposite sides
of the axle restricting motion.
Whenever the U-bolts and Torque Rods are loosened,
always support the nose of the axle with an adequate
jack.
Whenever the components are loosened, or the
suspension components attached to the axle are being
worked on, make sure that the locating features on
each component are properly engaged so that the
components are positioned together properly.
Using a hand held clicker-style torque wrench, always
“snug-up” the U-bolt nuts all over before torquing.
