4.0 Torque Rods - Technical Details

Purpose of a Torque Rod

• Restrain rotation of the axle housing during acceleration and braking
• Locate the axle and maintain alignment
• Control driveline angle
• Absorb leaning and cornering forces

 Key Technical Point:

• Transverse rods must be perpendicular to the frame rail when installed. If not installed properly:
• The inner pin could break
• The torque rod could break
• The bushing could walk out of the rod
• Warranty may be void

 When Should Rods be Rebushed or Replaced?

• Bent torque rod
• More than 1/8" movement at the rod eye. Check by hand
• or by prying against end with a bar
• Bushing material is torn or cracked
• Pin or sleeve in the rod eye is off-center (pin appears to be “walking out” of rod eye)
• Pin/sleeve is no longer located in the vertical center of the rod eye
• Bolt hole in straddle pins is stretched, elongated
