Idler Arm: Notes
NOTE:
Replace idler arm assembly if an up and down force of 25 ft. lbs. (110 N.m), applied at relay rod end of idler arm, produces a lash of more than 1/8" (3 mm).
NOTE:
On Camaro and Firebird, left and right ends of relay rod must be held at the same height. The side-to-side height control of the relay rod is controlled by adjusting the position of the idler arm. Before disconnecting the relay rod, it is important to mark the position of the idler arm on the frame in order to reinstall the idler arm in the same position. Whenever replacement of the idler arm or the relay rod is required, relay rod height adjustment must be performed. See RELAY ROD HEIGHT (CAMARO & FIREBIRD)
under ADJUSTMENTS.
