Need Some Help After Jackstand Failure

Hey guys and gals,

i had some fail this weekend when i was going to plastidip my wheels. I had the truck up on 3 TON jackstands with all of the wheels off and between the slight slope of my driveway and the soft asphalt underneath, one of my jackstands collapsed and the rear of the truck fell onto the ground.

Somehow the pumpkin did not crack and everything looked ok but now my dash looks like a christmas tree. My ABS, BRAKE, and car with squiggley lines lights are on and im not sure why. The truck drives fine with no clunks or anything so im looking for a little help in figuring out that this is. I think i remember this happening to a different car of mine when one of my wheel speed sensors broke but those are mounted high up on the drums so im not sure how they could have gotten damaged. Has anyone ever had this happen before?

-TIA

Picts of fail and WIN

 

Check the wire that goes across the top of the axle, I bet its cut or broke.

 

Glad no one got hurt. I don't believe that is a jack stand failure. No JS is designed to work on a slope.

 

its a very light curve in the driveway and i believe the corner of the stand started to sink into the hot asphalt which was ultimately what lead it to fail.

 

Sounds like a damaged abs sensor to me.

Glad you weren't under it when it happened. And yeah don't ever put a vehicle up on jack stands on any kind of slope. Also if you're on soft asphalt a small square of plywood under the stand will keep it from sinking in.

 

would a scan tool that can check ABS codes be able to tell me?

 

Yeah it should be throwing a code. But I bet it's pretty obvious if you look at the side that fell. Either the wires got pinched or the sensor itself got crushed.

 

Thanks for posting. All of us could use a little safety reminder now and again.

Glad you weren't injured

 

The scary part is...............I have the same exact jack stands.

 

But you won't ever use them on a hill

 

You'd be surprised what I'm capable of.

I applaud the OP for posting this. He might just save someones life.

 

you guys keep saying this was on a "hill" but you would be surprised how slight the incline was. If you look at the truck picture in the OP, it was even less sloped then the top of the driveway where the truck is parked. Just goes to show you how careful you must be. Im no idiot and ive had jacks fail on me in the past which is why i always use jackstands but this was a real eye opener for me.

 

Scary stuff for sure. Hope you figure out your issue OP.

 

That's definitely a 10%+ slope.

Regardless glad no one got hurt, truck can be fixed.

 

Jackstands on asphalt are dangerous....I personally always try to use them on concrete

 

I'm so paranoid about cars falling on me that I used two jacks, two jack stands, and ramps when I put a Magnaflow exhaust on my Audi.

 

Same here - I usually throw the tires under the frame so just in case it comes down it doesn't come down all the way (if tires have to be removed of course) or keep the jack as a back up

 

This is why I like a truck. I don't have to put it on jack stands or a lift to do many things under the truck. I love cars, but I hate having to jack them up to do anything, like change the oil filter.

 

Nah, no chance that is 10%, much less alone >10%. 10% is STEEP , you will know right away when you are looking at a 10% slope.

 

Wow, scary. Been using jack stands, well since the dinosaurs were alive. Never had one fail. Knocked my '83 mud truck off the stands once, never a failure. No on the asphalt, yes on the ply wood under the stand. Something is going on if this has happened before, be careful and alert, for death is under there with you if things go very wrong.
Scary.
