Well, according to David tie rod end note, the car in addition to a handful of important electrical connectors with gold contacts, most of the remaining fittings are made of copper - zinc alloy, under normal circumstances, its reliability is guaranteed, but If the car long term at high temperatures, high humidity, bumpy operating environment, it is possible to produce these joints loose, corroded, poor contact and other failures, and some strange electrical faults are mostly arising therefrom.

    The first vehicle in the hands numb. When the vehicle speed above the speed, periodic noise chassis, and the cab doors severe shaking, strong vibration of the steering wheel until the tingling in the hands, which is due to the transmission direction of the balancing means is destroyed, and the splined drive shaft splined shaft and sleeve wear caused by excessive.

    Second, the heavy steering effort. There are various causes of steering system parts with tight rolling bearings and plain bearings, poor bearing lubrication, steering drag link, tie rod ball joint adjusted too tight or in oil, steering shaft and casing bent, causing seizure; front wheel Improper toe adjustment; ago sedan or frame bent, deformed insufficient tire pressure, especially the front tire.

    Third, the steering wheel hard to manipulate. Well, according to David tie rod end is understood that driving or braking, the vehicle is automatically biased direction of the road side. To ensure straight running, you must hold the steering wheel firmly, causing the vehicle deviation reasons: pressure on both sides of the front wheel specifications or inconsistent on both sides of the front wheel camber inclination or not equal on both sides of the front wheel bearings Inconsistent gap on both sides of the leaf springs or elastic camber inconsistent, left and right sides wheelbase difference is too large, the gap is too small wheel brakes or brake drum out of round, causing the side of the brake issuers, dragging the brake, the vehicle is loaded unevenly and so on.

    Fourth, the direction of hair floating. Is often caused by driving the front wheels swing, when the vehicle reaches a certain speed, or shaking occurs because the steering wheel shimmy are: shimming tire or tire repair damage caused by the front wheel assembly balancing, the drive shaft of the total to have loose parts, drive shaft assembly balancing is destroyed, the shock absorber failure, steel spring stiffness is inconsistent, loose steering engine wear, improper front wheel alignment.
