Q: How Do You Inspect the Control Arm Ball Joints on Dodge Ram 3500 and Ram 3500?
A: To inspect the control arm ball joints, check for looseness whenever they are separated from the Steering Knuckle. Try turning the ball stud in its socket with your fingers. If the ball joint is loose or the ball stud can be turned, it needs to be replaced. To check the upper ball joints, raise the lower control arm with a floor jack until the tire barely touches the ground. Use a large pry bar between the upper control arm and the steering knuckle, prying upwards. Up to 0.020-inch movement is allowed, and a dial indicator can be used for precise measurement. If necessary, replace the ball joints following the specified procedures. The lower ball joints are inspected similarly but with the tire off the ground. In both cases, if replacement is needed, use the appropriate press tool and receiver cup, or take the vehicle to an automotive machine shop or a qualified repair facility for the replacement. Note that the availability of replacement parts may vary depending on the vehicle model, so check with your local auto parts store before disassembling the vehicle.
