* High Center of Gravity: G20 vans are tall and boxy, giving them a high center of gravity. This makes them inherently more susceptible to being pushed around by strong winds. The wind acts on the large, exposed surface area, creating a significant force that can overcome tire grip, especially at higher speeds or with crosswinds.
* Worn Tires: A 1992 van likely has aged tires with reduced tread depth and potentially degraded rubber. This significantly reduces the grip available between the tires and the road surface, making the van more vulnerable to wind gusts.
* Suspension Issues: Worn-out shocks, struts, or other suspension components would reduce the van's ability to maintain contact with the road. This exacerbates the effect of the wind by allowing the van's body to be more easily swayed and destabilized.
* Poorly Balanced or Aligned Wheels: If the wheels aren't properly balanced or aligned, they'll vibrate and have reduced contact with the road, contributing to a loss of control, especially when already compromised by wind.
* Crosswinds: Crosswinds are particularly dangerous as they push the van sideways, potentially causing it to lose control or even veer off course.
* Loose or Damaged Steering Components: Worn tie rod ends, ball joints, or other steering components could make the steering feel vague and unresponsive, making it harder to correct for wind-induced movement.
It's crucial to have a mechanic inspect the van's tires, suspension, steering, and wheel alignment. Ignoring these issues could lead to dangerous situations, especially in windy conditions. The sensation described is a warning sign that the vehicle is not roadworthy and requires immediate attention.
