Clunking noisesA clicking, popping, or snapping sound when the wheel is turned and eventually turn into a squeaking sound at the end of a stop, when the gas pedal is used, and/or when turning the steering wheel.2. Steering wheel vibrationDry ball joints have dramatically increased friction and can cause the steering to stick or be more difficult. Excessively worn bushings or ball joints can cause wheel shimmy, which may cause vibrations that are felt in the steering wheel. Vibrations may increase during acceleration and smooth out at higher speeds.3. Steering wanderingExcessively worn ball joints, bushings, or a combination of these can cause the vehicle's steering alignment to shift, which may cause the steering to pull to the left or right when traveling down the road. This will require constant driver correction to steer the vehicle straight.
