82 924 NA

Using a 2 ton floor jack

Where do you place it to jack the car front and rear?

Thanks

I tried replying to this earlier and had a bunch of stuff keyed in, then accidentally hit Esc and it all disappeared. SOaB!

Anyway I'm all calmed down now and on the notebook with its lower keys. As I tried to say before, to jack the whole front at once, I put the jack under the center of the crossmember. My jack is a bit high to fit there, so I have to lift the car while pushing the jack under with my foot.
For the rear, I put it under the gearbox - centered between the cv joints I think. (It's real obvious where to put it when doing it, just not 100% sure where that is right now.) Been doing that for years with no problems - I have the Audi (not snailshell) gearbox.
the jack I use -->

Depends whether you want to lift a side or either end.

If you want to lift the front I drive the car onto a couple of small timber ramps 2 inches thick and 4 inches wide. I then stick the trolley jack under the car and jack of the cross member under the engine. This is located at the very rear of the under tray. Before you do it this way check to make sure the jack is actually on the cross member. It’s easy to jack on the under tray which means you’re jacking on the sump. I’ve put dazzle paint on the point I jack on to make sure any one else uses the right spot.
For the back I use the gearbox casing (931 snail shell transmission). If I’m only jacking one side at the rear I slip the jack under the shock mounting point or the flat area where the torsion bar tune mounts to the body.

To jack a side I drive the car on the same wooden blocks and then slip the trolley jack under the sill. I then use a special adapter that fits into the round end of the trolley jack and fits the little indentation in the sill where the normal car jack goes.

Usual proviso is when you got the car in the air unless you’re just changing the wheels don’t get under it unless you’ve put axle stand sin place or something else so that the car does drop on you.

I normally put my axle stands arm at the front under the chassis rail just behind the rear bush mount for the lower, or on the cross member just by the front suspension bush mount. At the rear I put the stand son the flat section of the torsion bar carrier.

I never lifted up the back on my 82, but I'm pretty sure you lift it by the transmission casing. It says in the tech section of 924.org. For the front, use the crossmember, but make sure you dont hit the oilpan.

Do not put the jack directly onto the transmission casing, put a piece of wood on the jack first or as the FAQ reccomends use a hockey puck.

everything should be the same for the 924S as well. By looking at the illustrations on my 924 manual you should be able to jack the back end up on the automatic tranny as well.

Just to update this....

Today I wanted to jack the driver's side with the floor jack and used the normal jack point in the center of the car. The floor jack is slotted and fit nicely in this area and the car lifted without incident.

Thanks for everyone's advice. However, while the rear of the car makes perfect sense the front does not. Does the shield hide the cross member? I can't really tell where to place the jack on the front. If I'm looking at the right spot, it seems the jack would be well under the car and the handle isn't that long

Yes the sheild covers the cross member. The jack pad actually comes in contact with the end of the sheild. If you get behind the front tires and look forward you will see the cross member.
