I am talking about Jack Stands only. Maximum allowed time car should be on jack stands is one hour only.
Where have you heard this thing??
Is it mentioned somewhere ,
on a jack stand itself or in a manual or something?? Please clarify!!
There's a difference between
a jack and a jack stand. I've often left my cars on
jack stands for days, but never on a
jack.
Actually regardless of type, a jack is prone to failure: they are designed to raise and lower, not to hold for long .
A jack stand on the other hand is a solid piece of metal and is designed to hold. Provided the car is on level ground and wt. is evenly distributed.
I am talking about Jack Stands only. Maximum allowed time car should be on jack stands is one hour only.
How can you work ,all your work, in
one hour only?
How can anybody (all over the world) complete a DIY in limited span of
1 hour only?
What do you recommend if not a jack stand then, if one wants to work on a car ??
