TRANSVERSE TORQUE ROD
PRIMAAX EX / PRIMAAX SUSPENSIONS INCORPORATE TRANSVERSE RODS FOR VEHICLE STABILITY. IF
THESE COMPONENTS ARE DISCONNECTED OR ARE NON-FUNCTIONAL THE VEHICLE SHOULD NOT
BE OPERATED. FAILURE TO DO SO CAN RESULT IN ADVERSE VEHICLE HANDLING AND POSSIBLE TIRE
CONTACT WITH THE FRAME. OPERATING A VEHICLE WITH NON-FUNCTIONAL TRANSVERSE TORQUE
RODS CAN RESULT IN LOSS OF VEHICLE CONTROL, SEVERE PERSONAL INJURY, AND PREMATURE
COMPONENT DAMAGE.
NOTE
Some torque rods assemblies equipped PRIMAAX EX / PRIMAAX suspensions have curled end
hubs and are not re-bushable. The entire torque rod assembly must be replaced. This feature
provides superior bushing retention in the torque rod end hub.
■
These torque rods can be identified by the part number 67428-XXX or the suffix N after any
part number (i.e. 62000-615N).
DISASSEMBLY
