1997 Chevrolet Astro Van Torque

The 1997 Chevrolet Astro Van lug nut torque specification is 100 ft-lbs. This is the manufacturer-recommended torque value for all wheel lug nuts on the Chevrolet Astro Van.

Always use a calibrated click-type torque wrench and tighten lug nuts in a star (criss-cross) pattern. After mounting new wheels, tires, or rotors, re-torque after 50–100 miles of driving to account for settling. Over-torquing causes warped brake rotors and stretched studs; under-torquing risks wheel separation.
