Can I use just a hydraulic jack without jack stands?
Hydraulic jacks are mechanical lifting devices rather than secure structural supports, meaning they can fail without warning and should never be relied on alone. Attempting vehicle maintenance under a car held only by a jack creates an extreme safety hazard that prevents safe repairs when proper equipment is financially out of reach.
