Was out in the shop yesterday and while putting the car up on jack stands I noticed a piece of cast metal that fell off of the stand. I immediately thought that it was one of the teeth on the adjustible stem but on closer inspection it was actually part of the cog that holds the stem in place. If that piece would have failed when I was under the car I might not be here to warn you all. Please go out and inspect your jack stands for cracks/wear in the teeth and the cogs. These were the style of stands sold in Sams clubs, wally world, harbor freight, ect. Worthless chinese junk!! I will be buying new and different styles tomorrow.

Maybe that's why I always try to use at least two sets of stands or 1 set backed with the floor jack. Even with the extra safety, I still cringe each time I go down under.

Good heads up.

I've never been a big fan of those ratcheting -type of jack stands. We use them in the shop for big trucks, but usually won't be under the truck and it's usually backed by a 22 ton floor jack. I still use the old style post style, held in place by the thru pin. My Grandpa gave me some 35 years ago and i still use them. To me, they are a whole lot safer.

I am the same way. I even usually throw some old rims up under the frame rails to, to help catch and stop it from falling if it ever did.

Been criticised by more than a couple guys visiting my garage re thru-pin jack stands. Have used them for years and they are still in use. Have an old set of AMERICAN mfg. racheting truck jacks. They are old and just don't trust them without backup.

I would not trust a 3 legged jack stand with a sheet metal through pin. I'll take my chances with the ratcheting type, backed with a jack. Why on earth would you trust one ton of metal to a sheet metal through pin? Scary!

I hope no one is using a sheet metal through pin, instead of a solid pin I use solid pins, both in the jack stands, and towing 5 tons behind my truck, with the trailer and load held onto the tow hitch by a pin (course there are 2 safety chains)
