If you've got all four wheels off the car, it's pretty easy to slide a couple of them under your subframe connectors to give you a bit of safety margin....

My car has been on jackstands for 4 months now. It is still solid as a rock. No worries if done correctly!!!!!

 

Hey tanmanski,
I'm not scared of going under a car. If I was, I surely would not be putting an LT1 in my '72 Vega. I was referring to the fact that some people just toss a jackstand underneath their car and think that they're safe. Jackstands CAN kill you, if you're stupid enough to not check before you get underneath.

I prefer to use an old set of rims for just this purpose. I jack up the car with my floor jack and place a rim under each wheel. If the car is not high enough, I 'step' up the car and each time place wood blocks underneath the rims until I get to the desired height.

I've also done the same thing but with the frame of my truck resting on a piece of wood (to protect the frame) with rims underneath the wood. It's more sturdy than with the truck in park, and much safer.

Again, I was just saying that if you're stupid you can still kill yourself. Oh, and never put the jackstand 'half' underneath the jackstand. That's probably how that guy killed himself. I always, always make sure the whole vehicle is centered on my supports, I vigorously shake the car and I get in and out once to see whether the car wobbles.

Later!
