Uneven steering wheel turns left and right can be adjusted through coarse adjustment, fine adjustment, and steering wheel position adjustment. Here are the relevant steps: 1. Coarse Adjustment: Drive the vehicle onto a four-wheel alignment machine. Under the premise that the camber angles of both wheels are basically symmetrical, adjust the adjustment nuts of the tie rods to make the lengths on both ends as equal as possible, and make the toe-in on both sides symmetrically approach the same value, such as 0 degrees. If there are always contradictions in the above work, it is estimated that the frame or suspension may be damaged or deformed, requiring frame adjustment or part replacement. 2. Fine Adjustment: Use 5053 to check whether the angles when the steering reaches the limit on both sides are roughly symmetrical, within 5 to 10 degrees. Then, find the electronic zero position and immediately fix the steering wheel. Perform a four-wheel alignment according to the standard or required value. After completion, drive the vehicle off the alignment machine, reset the G85, and conduct a short road test to see if there is any deviation. If there is deviation, realignment is needed, and compromises may be required in the alignment values. 3. Adjust Steering Wheel Position: Turn off the engine, remove the airbag module, connect 5053 with the ignition switch in the self-test position (there may be an alarm), set the steering wheel to the electronic zero position, then use a puller to remove the steering wheel and adjust its position. It is best that when 5053 indicates the steering angle zero position, the steering wheel's vertical spoke is as vertical as possible. After completion, reinstall the airbag and other components, then clear the fault codes.
