Final answer:
The jack stand should always be positioned under a load-bearing, solid part of the vehicle to ensure stability and prevent damage to the vehicle and the stand itself.
Step-by-step explanation:
When using a jack stand to support a vehicle, it should always be positioned under a load-bearing, solid part of the vehicle for several reasons:
- Supporting a vehicle at a weak support point does not offer the required stability. This can lead to the vehicle toppling over, causing injury or damage.
- The jack stand cup can easily damage an unsuitable part of the vehicle. For example, if the stand is placed on a plastic or weak metal component, it can cause dents, cracks, or even breakage.
- An unsuitable support point can also damage the jack stand itself. If the stand is not properly aligned with a sturdy part of the vehicle, it may not be able to bear the weight and could bend or collapse.
