Can someone explain to me.., what it means to index torsion bars? Options

I've heard this mentioned when lowering the front end, but I'm not real sure what it means. Do the torsion bar adjusting end caps have to be in the same spot (same number of splines) on each torsion bar? If not, and you start cranking on the adjuster till the ride height is even, would one bar be more pretensioned than the other? Does any of this make sense???

What's happening is that I lowered the front of the car, not a whole lot, and added the bump steer kit, but when I go over a bump, the front end feels light. It feels like I'm still getting some bump steer, or something. I'm not quite sure how best to describe it. I haven't had it aligned yet, so that could be part of the problem, but I want to make sure I have everything else set up right first, then get it aligned.

Sorry for the long post, and thanks,

Back to the first part of the original question--

When we say "index the t-bars", what we usually mean is to take the adjuster off the aft end of the torsion bar, and put it on in a different orientation. Sometimes called "re-clocking". The idea is that if you run out of adjustment with the adjusting screw, you can move the whole part a fair amount by putting it back on the torsion bar's splines in a different orientation. That lets you start working the adjusting screws again.

The pre-load determines the ride height, so don't worry about it getting off without you knowing it--if you change the pre-load on the torsion bar, the ride height will change. That's what you're doing when you fiddle with the adjustment bolt, and also what you're doing when you "re-index" the torsion bar.

Not sure on your bump-steer-like issue. Could be something as simple as loose universal joints in the steering column...
