 |
|
hi 924 community
i just realized that while jacking the car up and then setting it on the stands with the longitudinal bars under the car, the longitudinal bars have started to compress and unevenly so
since i figure i always lift the left front quarter 1st, the inside of the bar contacts the jack stands 1st and it has begun to collapse accordingly 
should i worry about this?
if so, then any particular solutions?

Don't use a floorjack directly on the car.
And put a hockey puck on top of the jack head to cushion whatever you are lifting.
I have always placed a length of wood 2 X 4 on top of the jack head, and on top of the jackstands
And I haven't put any dents into the bottom of my cars. |

I only use the frame rails to lift the car as a last resort. My preferred approach is to lift the front from the center of the cross member (being careful not to position the jack too far back such that it catches the oil pan). At the rear, I lift the car from the lowest point on the gearbox.
This approach allows you to lift the car as evenly as possible on both sides, making it a simple matter to then position jackstands. I place the jackstands at the front of the frame rails just behind and inside of where the A-arms attach. At the rear, I place the jack stands under the end of the torsion carrier on the round tubes that stick out from the spring plate cover. In my experience, this lifting technique and these jack stand locations provide the most stable method of getting the car off the ground.

Yeah, doesn't that suck. 32 years will do that!!! Someday I hope to drop the entire suspension and clean it up properly.

I can say, Holy Toledo Ohio, what rust! Here in the rusty belt of Minnesota, since we don't drive our 924s in the snow, well, most of us, neither of my 931s have a speck of rust on them. Neither do the two parts car n/a 924s!!!

The 77 I have was a daily driver year round in up state New York for many years and then sat unused in a garage for 20 years. It really is just surface rust but looks bad.

No, that's on the torsion carrier itself. It's an OK position, but I like the spot on the other side of the spring plate, on the very end of the torsion bar where it sticks out between the frame rail and the pinch weld on the body panel. Also, I don't use that kind of jack stand...mine have a slight U-shape to them such that the torsion bar is cradled in the U-shaped top of the jackstand, greatly reducing the likelihood of it slipping out. With the style of jackstand in your photo I don't think I'd use any of the round spots, I'd try to find a flat spot to rest the car on.
{EDIT}
The reason I like the torsion tube is because it gets the jack stands as far apart as possible, which makes the car more stable when elevated, and also gives me more room to maneuver while rolling around underneath there...

Yeah, I realized that the U-Top jack stands would be better but I really hate the cam based jack stands and prefer the pin based ones. I just feel safer with them. I still haven't found a good pin-based stand that has a U-Top. The top of the stands I have have a thick rubber puck built into the top. When the car's weight is placed on them, the rubber compresses and creates a little U-Shape. I've given the car some pretty big shoves while up and she doesn't budge at all.
As for the jack stand location, my garage floor is a pock-marked wreck. I can barely roll my tool cart around so a creeper is out of the question. If I move the stands outboard more I was worried about the torsion bars themselves not being able to take the weight since one end is not supported. But if you say it works, I trust you!!! I'll give it a try next time.

How's the level of your gearbox oil with that outdrive leak?

It actually wasn't bad at all. Stuck my finger in the top plug and could feel the fluid. I think it was a REAL slow leak. Just another on the long lift of things I have to fix. 
Edit: Now that I look at the picture again, I bet thats all the penetrating lubricant that I shot when I was getting to remove the axles. I should take a look again now that the tranny is on my bench.

I realize this is an old post...sorry. Anyway could we persuade one you to provide picture that clearly defines the placement of jackstands on the front?
