Harbor Freight just sent out a recall for their 3 and 6 ton jack stands ..they are failing.....................
Harbor Freight is now recalling its Pittsburgh-brand three- and six-ton jack stands over risks that they could collapse during use, according to a filing with the National Highway Traffic Safety Administration (PDF) from March 20, and first reported on by The Drive on Tuesday.
The company is specifically recalling 454,000 units with model numbers 56371, 61196 and 61197. You can find these numbers (PDF) on the label on the top part of the stand on three-ton units, or a yellow sticker on the base on six-ton units.
According to Harbor Freight's NHTSA filing, the problem with these jack stands is that due to worn tooling at the factory, the pawl that engages with the toothed height-adjustable part of the stand doesn't do so sufficiently to reliably lock it in place. A bump or a knock could cause the pawl to disengage, dropping the vehicle suddenly.
