13. Frame Bracket Replacement
IMPORTANT: The Neway
brackets are symmetrical and can be
installed on either side of the vehicle.
Typically an adjustable frame bracket is
located on the road side of the vehicle
and a non-adjustable frame bracket on
the curb side of the vehicle. Be sure one
non-adjustable and one adjustable frame
bracket is used for each suspension.
1.
With the vehicle unloaded and/or trailer disconnected
on a level surface, chock the front tires to prevent the
vehicle from rolling forward or backward.
2.
Raise the rear of the vehicle using the vehicle's lift points.
Refer to procedures provided by the vehicle OEM.
3.
Support the vehicle frame using jack stands and remove
the tires (Figure 46).
Failure to properly support the vehicle
prior to commencing work could create a
crush hazard which, if not avoided, could
result in death or serious injury.
4.
Using floor jacks; support the axle at the axle bowl and the lower
the control arm assembly at the transverse beam (Figure 46).
IMPORTANT: Be careful NOT to gouge or mark the
transverse beam with the floor jack.
Failure to avoid gouging or marking the
transverse beam could cause component
failure and loss of vehicle control which, if not
avoided, could result in death or serious injury.
5.
Using two floor jacks, support both sides of the lower
control arm assembly near the pivot connection (Figure 46).
Failure to properly support the suspension
during maintenance could allow the
suspension to fall which, if not avoided,
could result in death or serious injury.
6.
Exhaust all air from the system by disconnecting the link from
the lower connection of the height control valve and pulling
down on the link (Figure 47). Refer to the height control
valve manufacturer's instructions for further information.
7.
Disconnect the air supply line from the air spring.
NOTE: If the air spring has a leak and is deflated, Step 7
MUST still be performed.
8.
Remove and discard the pivot connection bolt and fastening
hardware at the pivot connection (both sides) (Figure 48). Refer
to SRK-643 and -644 in Section 4 for replacement hardware.
IMPORTANT: Be sure to note the positions of the spacer
washers between the frame bracket flanges
and the pivot end of the lower control arm
assembly (Figure 32 and 48).
