The original car was used to control the rudder driving. Rudder can not be that bad, but it will produce cars with intense vibrations transmitted to the driver, increasing the difficulty of its control direction. When the engine is installed in the front part was changed, due to increase in the weight of the steering wheel, the driver simply no way to drive a car car rudder. The new steering wheel design was created, it is introduced between the driver and the wheel gear system is flexible, well isolated severe vibration from the road. Not only that, a good steering wheel for the driver system can also bring a feeling of intimacy with the road.
Kero  Throttle Body     to remind: the steering wheel because often with the hand, is easy to dirty, sticky hands if it will affect driving attitude, as long as the water and wipe clean on it. If we add a little detergent decontamination easier, but be careful with water to wipe clean.

Steering wheel of the material can be divided into three types: urethane, leather and wood, most of which are urethane, it is easy to dirty. Premium leather used car lot, it is difficult to remove dirt, if dirty clean, it will slowly become difficult to clean, leather easy to change. Must be noted: the surface of the resin-treated wood, dirt is easy to fall off, change the old wood post, sometimes the resin will produce cracks.

     For some years longer cars, the steering wheel is to determine a condition based on today put this method to others.

     When traveling at moderate speed above the chassis is cyclical noise, severe shivering cab and doors, steering wheel strong vibration, until the hand numb. This is due to the direction of transmission balancing is destroyed, drive shaft and spline shaft and spline bushing caused by excessive wear and tear.

     Causes heavy steering effort steering system has various parts with tight rolling and sliding bearings, bearing lubrication bad; steering vertical rod, tie rod ball stud adjusted too tight or starvation; steering shaft and casing bent, causing catching; improper adjustment of front toe; front axle or frame bent, deformed; insufficient tire pressure, especially the front tire.

     Difficult to manipulate the steering wheel when driving or braking, the vehicle direction is automatically biased side of the road, in order to ensure straight running, it must firmly hold the steering wheel. Causing the vehicle deviation reasons: pressure on both sides of the front wheel specifications or inconsistent; sides of the front wheel caster angle or camber are not equal; Yi bearing clearance on both sides of the front wheels is inconsistent; leaf springs on both sides of the arch degree or elastic inconsistent; left and right sides wheelbase difference is too large; wheel brake gap is too small or out of round brake drum, causing the side of the brake hairpin, the brake Dragging; vehicle loading uneven.

     Direction "flighty", often by driving the front wheels "swing" caused. According Kero  Throttle Body     aware, when the vehicle reaches a certain speed occurs when the steering wheel shaking or shimmy reasons: shimming tire or wheel balancing vehicle repair damaged caused by the front wheel assembly; shaft assembly with parts loose; shaft assembly balancing is destroyed; shock absorber failure; leaf spring stiffness is inconsistent; steering engine wear Songkuang; improper wheel alignment.
