She lists to Port in rear, Suspension height difference Options

[Gatornapper]

One of the first thing I noticed when I picked up my sweet barn find 914 4 years ago was a height difference in the rear (only) - she lists to port by 1/2".

I have the service record from the local Porsche dealer that about 3,000 miles prior to my getting the car, their shop had replaced the left rear trailing arm bushings. In working extensively on my 14 for the last 4 years (my shop has a lift), I can find no cause for the 1/2" height difference in the body at the rear axle center.

Car had 60k original miles when I got it, now 63,600. I believe rear spring/shocks are original, and show no issues.

Any help would be appreciated as to cause and fix for the list.

TIA,

GN

jack the front slightly from the center of the cross member to take most of the weight off of the front (do not have to lift the tires off of the ground) and see if the rear straightens out. If so the front torsion bars are out of adjustment

George -

Thank you again for your perfect analysis. But your diagnosis was not only correct, but solved another more important problem that I did not know I had.

Setting the torsion bars to spec did indeed solve the height difference between left and right.

But it did something far more important.

Having never checked the torsion bar settings, I found both to be completely loose. This means that the bars (springs) were not in effect until after the suspension was activated by a bump in the road or a turn. There was slack on both bars!

Setting both bars to spec leveled out the car, AND tightened up the handling noticeably - to my great pleasure. It was almost as if I added sway bars! (winter project).
