1. Worn Steering Rack: The steering rack is a critical component that connects the steering wheel to the wheels. Over time, the components within the steering rack can wear out, leading to play or looseness in the steering.
2. Loose Steering Linkage: The steering linkage consists of various components that transfer the steering wheel's movement to the steering rack. Loose or worn components in the linkage, such as ball joints or tie rod ends, can cause excessive play.
3. Worn Steering Column: The steering column connects the steering wheel to the steering rack. If there is excessive play or looseness in the steering column, it can contribute to play in the steering wheel.
4. Worn Steering Wheel Assembly: The steering wheel itself and its mounting mechanism can also develop wear and looseness over time.
To properly diagnose the source of the play in the steering wheel of your GTO, it is recommended that you take it to a qualified mechanic or automotive technician for inspection. They will be able to assess the steering system components, identify the specific issue, and recommend appropriate repairs or replacements.
