Need Some Help After Jackstand Failure

Glad you're okay OP. I've had something like this happen to me before and it scared the lights out of me. Now I make sure to triple check everything I'm doing when lifting anything.

 

So do I...but I doubt it was the jackstand that caused the issue...as stated above, try to be on cement when working on vehicles and always put a pad under them if on black top (especially when is hot out). When we used to ride bikes I was amazed at the number of Harleys and such that fell over from folks using the side stand on asphalt on a hot day. Glad no one got hurt from this event, the post about putting the wheels under the frame is also a great idea. Had a friends son get killed from a similar accident about 25 years ago.

 

You can also get the jack stand rubber pads for them to go on the top so that the metal stand doesn't slip on the metal frame, axle tube, etc... They sell them at Harbor freight cheap, keeps the vehicle planted on the stand. They main key is to make sure when you're setting the truck down onto the jack stands to double check the stands are on the mounting surface evenly or it can slide off which is what I'm thinking is the case here, not judging, everyone makes mistakes.

 

Why not weld base to that jack stand and never have an issue, plus have guarantee they will not collapse? If you working on uneven surface the only thing to make sure jack stands will be safe is to weld base.

 

The fault can be anywhere in the lead wires, and it'll still register as a faulty sensor.

Take your best guess based on where the jack stand was originally positioned about what it might have damaged or broken when the truck fell on it.

 

So what you're saying is if the truck is on a stand and it begins to lean on hot asphalt, it will fall over?????... I think that's what happened to the OP.

Thanks Bill, I think that's what happened in the OP's case.

 

Maybe you are on to something...

 

thanks for the help guys!

 

What's interesting to me is that my driveway is concrete, yet has a slight slope. Very slight. I've always been aware of this but reading this thread will lead me to take more precaution. I've always been a fan of throwing the tire under there. Even though it's the asphalt that's the issue, one can never be safe enough. Glad you are still alive.

 

As far as I know the abs line always stay in loose position once its tension or got tighten its damaged and need to be replaced. It might still look good on the out side as nothing happens but inside the insulation might already be destroyed. Hope this is not the case. Not to say im an ass of jack stands but I have 4 sets of jack stand ranging from 3-12 tons. Anytimes I work on my trucks the 12 tons jacks are my 1st choice I even secure with the 2nd set. A truck can be replaced but you are not. Great to hear no one got hurt.

 

so i finally got a chance to get under there and the right rear speed sensor wire has a nice gash in it right through one of the wires. I see there are 3 part numbers listed for this so how do i know which one i need? I have an 09 ACLB TRD MTX

 

I'd ask a dealer to run your VIN and tell you which part number is needed

 

Glad you're ok op I've had a jackstand fail on me before and not saying yours did or didn't but it was the scariest second of my life when I heard a pop followed by a crashing 2007 roush mustang slamming onto the ground. Especially since I had just been full body underneath it installing a new shifter.

I wouldn't use those mats I'd get some plywood or weld a base to your next set.
