Torque Rod: Description and Operation
ANTI-WINDUP BAR
The anti-windup bar compensates for rotational torque placed on the rear axle during acceleration and braking by preventing the rear axle and rear
spring from twisting (winding up).
The anti-windup bar minimizes noise and vibration issues caused by excessive pinion-to-driveshaft angles during acceleration and braking.
