It connects the axle housing to the chassis frame, preventing the axle from twisting during acceleration and braking, which maintains driveline angles and stable handling. When the bonded rubber bushings wear out or crack, you get clunking, vibration, and wandering steering, so it needs replacement. This specific 25-9/16 inch rod fits Peterbilt Low Air Leaf and Flex Air suspensions along with Kenworth Airglide 380 systems; it is a non-rebushable unit, meaning the entire rod must be replaced when the bushings fail.
