Default Car on Jackstands for a Week....Possible Comprimise Chassis Strength..?!

Well I am in the process of a motor swap and left the car on jackstands with the entire front in the air and have left it like that all week......it kinda got me to thinkin about whether or not this is really gonna weaken it any.

Posted it here cuz on a true track guy would care to even answer this...and I really need to know how fragile are these cars anyways (hatchback EH2)!

Thanks a Million pesos for you

LOL, if jackstands for a week weaken the car I'm in big trouble. My car has been up on jack stands since august I think. Too long to remember.

You got nothing to worry about.

My racecar has been on jack stands all but a few days since 1998.
My dad's '31 Pontiac was on stands in storage from the late 1950s until about 1976 and since then in 2-5 year stints.

Not to worry so long as it is sitting squarly and stabley. If the front was up on one high stand alone for an extended time then I might be concerned.

Not really a good idea to leave a car on just two jackstands (for safety). Better to jack it up on four (okay, sometimes I do it on two if I'm in a hurry)

Thanks for the peace of mind. Hope to get the motor in by SAT.

Wish me luck!

Really? Every time I try to put my car on four stands I come very close to the first two stands falling over while raising the opposite end. One of my cars has had the front end on stands for several weeks now. I can't imagine it would hurt anything as long as you use the factory specified jacking points.

If the wheels on your jack are able to roll properly when lifting the car, this should not be an issue. Not always easy on non-smooth pavement if the jack wheels get stuck.

Good point, John. However, with my VW, I have to raise it from the sides, one corner at a time. Now, thanks to the huge rear swaybar, raising from either the front or rear of one side tends to raise the entire side of the car. That's when it gets sketchy, with the car sometimes teetering on only two points (jackstand and jack.) Anyway, it's not a big deal. I don't really *need* the car on four stands, and given California's propensity for earthquakes, don't really mind having half the car on the ground at a time.

I read an article in a BMW magazine that gave suggestion to people who plan on storing the car on jackstands during winter.

They suggested to take the wheels off because the suspended weight might cause extra stress on the balljoints, driveshafts, and all the rubber components like boots and bushings. Other than that, it should be fine.

You should also show your car on-track video's a couple of times thru the winter just so it doesn't get depressed too.

Scott, has always wondered if you jack the car up to0 many times will the chassis fatigue and crack?
