hey everyone

sorry if this is a stupid question:

i've got to put my 914's ass high in the sky this weekend for some exhaust work. i've only got one floor jack and 2 jack stands (+ the stock jack, but i'm thinking that's not going to help me here).

where should i jack from? the transmission? this can't be good for the tranny mounts...

on a related note, where does everybody jack from when they're just lifting one side?

thanks, nathan (IMG:style_emoticons/default/beerchug.gif)

I use the transmission as a jacking point, I see no problem with it as long as you are careful not to place the jack pad under the shifting mech.


when going at it from the side, I place the jack pad at the round donut shaped sheemetal on the floor

i like to put them on the shaft of the trailing arm - that's a place that's designed to support the weight of the car. if your tub can take it, the donuts are designed to be support points, and the farther forward you have the jackstands, the lower they have to be raised up...

Get yourself a length of 2x4, the length should be the width of the floor pan.

Use the floor jack to get the car up in the air, using the donuts.

Put the 2x4 at the back end of floor pan. Place jack stand under 2x4.

Repeat for opposite side. After raising the car, placing your jack (with a small block of wood) under the point where the engine/transmission mate will ease stress on transmission mounting points.

I've been jacking 914's under the tranny for years. I put the jack just forward of the rear cover like Mueller said. Put jack stands under the donuts on either side - out of the way and structurally sound.

For the front I pull the pad off the jack and lay a 1"x6" board across it to span between the torsion bar tubes, then place jack stands under the front donuts. (Note: due to low stance of car I have to lift up on the front bumper and push jack under with foot to get started)

This gets the car in the air really quick - only have to run the jack up once for each end. (Note: I use a big wide/heavy 3.5 ton floor jack. I wouldn't do this with one of those narrow little stamped sheet-steel floorjacks you see at FLAPS/Walmart/etc.)

Here is a picture of my car on two, yes two jack stands. I had it on three until my 7 year old girl picked up the front end, so I did a little shifting around and got it to balance on tow.
Don't try this at home.

This is kinda a stupid thing but a finally found a subject that I could post this picture with.

Before you crawl under, make sure your wife knows how to use the jack. (IMG:style_emoticons/default/laugh.gif)

It helps that you have the lightest 914 in the world with helium in the tires and in the roll cage tubes. (IMG:style_emoticons/default/laugh.gif)

i wouldn't use the tranny unless you have solid mounts.
if your jack is low enough, get it under from behind and use the engine cross-bar. that will get the car way up.

or, do it the old fashion way, jack up one side first, put the jack-stand under the side (trailing arm, see pic), then do the same on the other side ...

I put jack stands under the trailing arms too, after jacking at the rear donut, but I've always wondered if this is okay. I worry it may damage the arm or mounts. The trailing arm pivots do not normally support the weight of the vehicle, they only deal with the suspension location forces. The rear vehicle weight is carried by the springs, wheels and tires.
