Putting a 997 on jack stands - best way please.
Discussion
Hi,
I need to remove all 4 wheels from a 997 C4s and send them for refurb. I have four axle stands that I would prefer to put under the jacking points. No problem at the back where I can put the jack centrally at the back of the engine / transmission but not sure how to raise the front while leaving the jack points free. Or is there a good pint for the axle stand under the front suspension somewhere?
How do you home mechanics do it?
Thanks
Mark

Have mine propped up this very moment.
As you see there are several solid parts at the rear to prop.
On the front - use the jacking points to lift the car. Not far from the jacking point you will see a flat plate with 3 large nuts/bolts through it behind each front wheel. The centre nut passes through the plate and secures the front sub frame to the chassis. If you place a small block of wood under this nut and put your axle stand underneath, it will provide rigid secure support. Do this each side.
For ease, its helpful to drill a 25mm hole in the wooden block to allow the nut to sit in a recess and add extra security.

Getting the front done, as cmoose says, very simple to jack up the rear and prop the front.
The rear, always a bit questionable in my books to use the engine crankcase. The rear end weighs close to a tonne, I am not very happy to lift that weight via the engine mounts, that's near 500kg lift (stretch) on each mount (rather than just engine weight and torque compression, which is what they were designed for). Perhaps I'm just being too cautious perhaps no harm is done but perhaps the mounts are damaged.
So I built a bar that goes across the car at the rear and acts upon two "pucks" http://www.ebay.com/itm/PORSCHE-JACKING-PAD-JACK-9... fitted in the jacking points, that I can jack up the rear from (the bar) then I place small (short) jack stands under the bar and can remove the jack to lift the other side.
As an indication of the weight of the rear - I initially used 50mm square hollow section and when I started jacking up the metal bar just bent and bent and bent... even though the leverage was in the bar's favour... so I ended up having to weld two 50x50s together one atop the other.
