C5 III X7: Jack stands

[white exec]

That all sounds cautious and sensible, and what any good mechanic would do if aiming not to damage sills or bodywork.

My only exception would be to initially jack up (trolley jack) either at Z1 in your drawing, or further back along the flat part (below Z1 in the diagram), and then also place the padded axle-stands there.

Placing heavy card (or wood) between jack pad/axle prop and a flat surface is a really good tip, not just to avoid damage, but also to provide extra 'grip', and something for the steel surfaces to bite into.

I think Citroen's cautions about jacking probably have roadside owner wheel-changing mostly in mind, rather than any serious attention to the underside.

Great help here, thanks guys. I'll have a look at those subframe points when will need to jack it up again.
The bent lip will stay as it is for now as I don't have tools to repair it and I wonder whether it won't make it even weaker.

It'll be quite ok if straightened and painted.

That 'lip' is not there to take the weight of the car; it is to keep the jack (once it has been raised to start taking the weight) in place and not slip (assuming the car is on a level surface).

I use these ontop of my trolly jack and axle stands. no Damage as the cill At THE JACKING POINT sits in the groove.

I also have a jacking beam I made for the rear subframe,

I think the lip, which usually runs the full length of the sill, is there pretty much as a standard bit of construction and vertical reinforcement for the hollow sill structure. As such, it just about has sufficient strength to allow jacking of the car, recommended to be under the shaped 'jacking points'. Unfortunately, the added rigidity doesn't operate laterally, so the lip is easily pushed over. The pad is good, as it transfers the weight on to the steel either side. A shoddy arrangement, all the same, just-about adequate (on a good day).

Hello, the article talks about straightening a bent lifting point using a vice and a jack. How does it work?
The jack is only used to support and raise the vice to the desired height and the lifting point is straightened by squeezing it between the jaws of the vice, or it is also applied by the hydraulic force of the jack.
Could you explain it to me + some simple drawing.
Thank you.
Excuse my English, translator.

Hi,
Your English is fine! I don't think a drawing is necessary myself? Imagine, if you will, that the jack is simply there as a support for the vice (which is quite heavy). If you are really strong, forget the jack and lift the vice into place by hand! The vice is simply used to "crush" the damaged vertical lip of the jacking point back into being a vertical edge again. So that it points to the ground (if it has been bent or damaged beforehand). Place one jaw of the vice on either side of the edge that has been damaged and wind the vice handle to squeeze it and make the edge vertical again. I've also been known to use big pliers in my "strongman" days

I'd give the metalwork a coat of stone chip or underseal protection afterwards.

Incorrect position of the axle stand

ESSENTIAL: Do not position the stands under the jacking points.

Correct position of the axle stand

Hello everyone,

Just bought a (quite negleted) C5 X7 and I need to adress some things on it that will require jacking. I undestand that it is forbidded to put the jack stands under the jacking point but I cannot identify the correct location from the manual picture. Can anyone tell me where this is exactly or if you have a picture with the actual location on the car, it would be great.

Many thanks.
