Just for fun, I tried my spare cable. This screws on fine. Once again, stay away from the no-name brands.

Anyway, here is the new drive installed, with the cable screwed on as best as possible.

Without a rubber cap, I improvised with rubber tape.

OK, back to suspension work. I need to raise the front slightly, but the torsion bar caps are aready twisted as far as possible.

So I reset them rotated 1 spine.

I reinstalled the front strut tops, and got them aligned by eye.

After a first camber check, I removed one 2mm shim from the right rear.

Then I worked on adjusting the front.

Here's how I ended up with camber, measured with my old analog gauge and my iPhone app and tool. This time, I had no problem getting to -0.5° all around. The ride height is about 0.25" higher, but still where I want it.

For setting caster and toe, I will use a trick others have suggested: thin poly kitchen sheets to eliminate twisting friction.

With a pair under each tire, I should be able to twist the wheels more easily.

I set the caster (or castor) today. The process is straightforward: turn the front wheels a certain amount to the left, measure the camber, and then turn the wheels the same amount to the right, and measure the camber. For each wheel, the caster is then the difference in camber, multiplied by a factor based on the angle.

Here, the right wheel is turned 20° to the left, lined up with a guide on the floor.

BTW, in a 914 20° is a little more than one complete turn of the steering wheel.

After the first round it was close, and so I had to nudge the strut tops forward while maintaining the actual camber at -0.5°. Don't worry, the marker is dry-erase.

Here are my results. The caster spec is 6.0° and I got 6.2° on both sides.

Last thing today I set up the parallel strings for measuring front and rear toe.

Before I started working on setting toe-in, I reset the strings using cross bars. Much easier this way to maintain constant distance front and rear.

Here are my initial measurements, which I could repeat. Uneven in the front and toe-out in the rear.

To adjust the rear, I loosed the 3 bolts for the outer trailing arm mount, and then shifted the mount forward with some taps from the love hammer (using a bit of hardwood dowel).

Of course the front is more civilized, with adjustable tie rods.
