Uncle Jon’s Rookie Mistakes: The Single-Jack Stand Repair
Written By Uncle Jon
I was in a hurry to clear a jammed driveshaft on an uneven dirt trail, feeling completely fine lying on my back right up until two tons of truck shifted inches above my chest.
A while back, I had a 3/4-ton rig bound up on a rough patch of trail. Instead of taking the extra five minutes to pull out proper support, I shoved a hydraulic bottle jack under the axle, cranked it up, and slid right underneath on the dirt. I figured I’d only be under there for two minutes, so skipping the jack stands wouldn’t hurt. But while I was wrestling with the yoke, the narrow base of that bottle jack settled into the soft soil, tilted, and let go. The axle dropped with a terrifying thud, missing my ribcage by a couple of hair-thin inches and pinning my sleeve to the dirt.
That moment burned a permanent lesson into my brain: a hydraulic jack is a lifting device, not a holding device. Placing your body under a vehicle supported only by fluid pressure and a narrow foot on unstable ground is pure foolishness.
If you want to avoid my mistake, never crawl under any part of a vehicle that is resting solely on a hydraulic bottle jack, floor jack, or mechanical jack. Stop convincing yourself that a "quick two-minute job" justifies gambling with your life on soft or uneven trail ground.
Instead, always set solid, wide-base jack stands under the frame or axle before sliding underneath, and toss a sturdy wooden block or cribbing board under the stand's base if you're on soft dirt. For an extra layer of protection out on the trail, slide your spare tire flat under the frame rails so if everything else fails, the wheel catches the weight before it reaches you.
