HARBOR FREIGHT JACK STANDS RECALL (Page 2/2)
MarkS AUG 02, 12:23 PM
The older I get, the more hinky I get about crawling underneath a car supported by jack stands. Just spooks me anymore, especially when I'm a full 50lbs heavier then I was 'Back In the Day" when I would do it without a second thought. The posts I've read about Ethan Allen (yourfriendethan) are just so heartbreaking, a nice guy with a family..Dammit to hell!
Anyway, I think a good USA mfg lift is in my future.

I ran across a plastic set of these in a pile of aluminum ones and the weight difference was not apparent that was a scary thought. Also the cast aluminum I have seen on these can be very shoddy. If there was a good solid steel set of these maybe steel like the traditional stands but with this adjustment instead... however I also don't like how thin that threaded steel is. I've seen bent ones from RV leveling.

Just my opinion on those.


I've thought about that and have concerns as well. I like the jack screw idea but steel construction seems to make more sense but I did collapse an old steel unit that used a pipe, then split the steel to make the three legs . The old set of pin through stands that I have seems like the best idea and I have a set of those as well. Might try the Esco design. Those look sturdy. Expensive but what is your life worth?

Please No....
While nice because can adjust the screw so all are tight vs. pin or ratchet type jack stands don't use them to protect people.

Not only that...
The Aluminum frame can and will Fail because Al often hates point loads anywhere on the bottom.
See that happen when used to level RV and sunk to hit a rock over a weekend. Broke the bottom but didn't fail completely this time.

Had some given to me many years before that...
No-way use as jack stands to get under a vehicle. If you hit them w/ tools etc while working can "break" easy for same reason.
"Break" can be Break outright or Bent a "leg"and won't hold a load.
