What is the maximum play the towing fork may have in the bearing bushes in towing direction?

The correct answer is "No noticeable play." According to German vehicle safety regulations, the towing fork must fit securely in the bearing bushes, especially in the towing direction. Any noticeable play or movement can create instability and risk during towing, potentially leading to unsafe driving conditions. That’s why only a tight fit – with no perceptible looseness – is allowed. This rule ensures safe and controlled towing of vehicles. Always check for a secure and firm connection before towing.
