Seriously?? You can jack up the front end here?
All these years I've struggled to find a good spot to jack up the front end.
I came accross this image yesterday. Jacking this way wont damage the car? http://forums.pelicanparts.com/uploa...1691079501.jpg |
No.
|
I place a 2x4 between the suspension mounting points and then jack from the middle.

When you say "No" to my question "Jacking this way wont damage the car?"...does that mean it WON'T damage?

You can jack up the front end here?
Is what I was saying no to. 2x4 across the mount points is much better. That cross beam can not hold the weight of the car, maybe that guy is using the jack as a safety measure if one of the stands fails or something. |
To me it looks like that jack is there as a 5th jack stand to keep car either from teetering forward if that was the concern,just added stability to replace that suspension.
No, not a jack point. But the front or rear mounting points are structurally sufficient, the c-channel framing where that jack is located might not take a full load in the center of it and for that matter, the center of any beam is weakest point. |
In the photo you can see the car is sitting on two jack stands, (from an assumed total of four); would expect these are taking the majority of the weight.
If the cross member is rusty, (inside from leaked battery acid) it may crush or fail if used to as a single point to lift / jack the car. |
I have used that spot many, many times on my '75. I use it when I am adjusting front camber or corner balancing on the roll off platforms.
But it is a race car-- weighs about 700 pounds less overall than a street car. 99% of the time I use a jack plate in the side locations. 20+years.http://forums.pelicanparts.com/uploa...1691095530.jpg |

Upon inspection, say a #3000 911 with a weight distribution of 60 rear 40 front.. the front wheels of the car share a load of around #1200.. of course this is dynamic.. #1200... That cross member is really quite robust.. a rectangular section.. Unless its compromised by rust.. go ahead and do it.. Simply jacking up the car from there is fine.. I've done it countless times.... Here is one to make your head explode... Porsche family member jacking up a 911 by the engine ...FFS https://cdn2.pelicanparts.com/more_i...10963-7344.jpg |
I have jacked up a G50 88 911 from under the motor many times..... This 3.2 block does NOT have the round oval sump plate ...

I'm certainly no expert, but that's where I jack my car up from as well. I use a 2x4 to distribute the weight a bit, but with the boxed shape of the metal there, it seems like a perfect spot.
Of course I put stands underneath once I get it to height, etc. |
Nice. I'm going to do this next time I need it up without using quickjacks.
|
I use 2 floor jacks to get the car into the air. One in each jack slot on the sides. Raise each a couple inches at a time to keep things even, then lower it on to jack stands. Simple.

I have been jacking the front of mine in that spot for 20 years now. Like others I use a 2x4 to distribute the weight but it does the job. And mine is rusty haha. It was poorly repaired with fiberglass and I never got to fixing it. But that’s something I’m doing soon.

I don't even bother to alternate between each side. Jack up one side as high as I can, toss under the jack stands, move to the other side and repeat:

That's about all I'd do unless going very high on 6 ton stands, like high enough for an engine drop, in which case I'd go back and forth.
You have to be confident in the rollers on your jack, though, you don't want it fighting the car as it goes up! This sounds absolutely terrifying, though, why do it like this? Quote:

Pampadori's way of getting the car totally off the ground doesn't require 2 jack pads and 2 jacks so its more economical. Because I have 2 jacks, I figure there's less weight being shifted from side to side for whatever advantage that may have. Guess I like to see it going up evenly, but maybe that's just me. ;)

I keep a few short lengths of 2x6 around the shop to distribute weight while jacking up the 911 and 66 Bug. Belt and suspenders approach.
