After that, uninstall the idler arm (2) from the car by taking out the nuts (1) and bolts (3). Install the idler arm (2) onto the frame and put in the frame bolts (3), then screw in the nuts (1) and tighten them to 99 Nm (73 ft. lbs.). Screw on the relay rod (9) to the idler arm ball stud (1), so the seal is positioned appropriately and tighten them with J 29193 or J 29194 to reach 54 Nm (40 ft. lbs.) which will seat the tapers properly. Get rid of the twist-lock nut and add the idler arm ball stud prevailing torque nut (10) to the idler arm ball stud (1), making sure it is tightened to 62 Nm (46 ft. lbs.).
