Here are some common jack stand placement points:
* Frame Rails: These are the strongest points. Locate the frame rails just behind the front wheels and just in front of the rear wheels. These are usually the thickest and strongest parts of the frame. Make sure the stands are securely seated on the flat, level portion of the frame rail and not on any curves or welds.
* Subframe (if accessible): Some projects might require lifting the front or rear independently. If you're working on the suspension or something specific to an end, you might find suitable, sturdy points on the subframe. However, frame rails are generally preferred for overall safety and stability.
Crucially Important Safety Notes:
* Consult a repair manual: A factory repair manual for your specific 1991 Chevy S-10 model year will show the best locations and often have diagrams. This is the most reliable source of information.
* Use jack stands rated for the weight of your truck: Never exceed the weight capacity of your jack stands. Your S-10's weight will vary depending on its options and cargo.
* Always use jack stands in pairs: Never rely on a single jack stand to support the vehicle.
* Engage the parking brake: This helps prevent the vehicle from rolling.
* Chock the wheels: Place wheel chocks behind the wheels that are still on the ground to add extra security.
* Double-check your placement: Before getting under the vehicle, carefully inspect that the jack stands are securely positioned on a solid, flat surface of the frame.
* Work in a well-lit area: Make sure you have good visibility of what you're doing.
Improper jack stand placement can lead to serious injury or death. Always prioritize safety. If you are unsure about any aspect of this procedure, consult a qualified mechanic.
