The upper and lower control arms of your Hummer are immensely important for its normal functioning. They connect the frame of the car with the steering knuckle and keep the vehicle stable by ensuring a unison movement of the wheels and chassis. A faulty control arm can cause serious trouble for any vehicle. They lead to ball joint failing and can even cause the steering knuckle to get disconnected which ultimately leads to a lack of control on the car. Bad arm bushes of cars are highly dangerous for the safety of drivers. Uneven tire wear, clunking noises, and vibrating cars are primary symptoms that should never be ignored.  If you sense any such warning sign in your Hummer, get an immediate appointment with Desire Auto. Our team would fix the issue swiftly.
