When your 2020 Jeep Grand Cherokee makes popping noises while turning, components in the steering and suspension systems are creating impact sounds during articulation. Popping during turns indicates play or binding in parts that should move smoothly.
CV Joint Issues
Outer CV joints on the front axle shafts are designed to handle steering angle changes. When worn, they create a rhythmic clicking or popping sound during turns, particularly tight, slow-speed turns. The sound typically occurs on the side opposite the turning direction.
Ball Joint Wear
Upper and lower ball joints allow the steering knuckle to pivot during steering and suspension movement. Worn ball joints develop play that can create popping sounds during turns, especially when combined with going over bumps while turning.
Steering System Components
The steering linkage includes multiple joints - tie rod ends, drag links (on some suspension designs), and steering column components. Wear in any of these can create popping during steering input, particularly at the extremes of steering travel.
Strut Mount Bearing
The front strut mounts include bearings that allow the strut to rotate with steering. A failed strut mount bearing may pop or groan when turning, especially when turning while stationary or at very low speeds.
Sway Bar Components
Sway bar end links and bushings can pop when worn. During turns, body roll loads the sway bar system. Worn components may pop as they're loaded and unloaded during the turning motion.
4WD System Binding
If the Grand Cherokee is in 4WD mode on dry pavement, the system may bind during tight turns, creating popping or banging as the drivetrain fights against itself. This is normal 4WD behavior on dry surfaces - use 2WD or Auto mode for dry pavement driving.
