Well, it wasn't today, but...
In the last month, I rebuilt my front suspension (new ball joints, new Elephant Racing bushings and new turbo tie rod kit) and got an alignment, installed new front & rear struts & shocks and swapped out the 2.0 exhaust parts for 1.7 parts. Also adjusted the valves while the heat exchangers were out of the way.
It's amazing how much quieter the car is without the front torsion bars dragging on the inside of the control arms....
What do you mean by the front torsion bars dragging in inside of the control arms? I've not heard of this issue before but there's a lot I don't know.
The control arm is attached to the car with rubber bushings, one at the front that is clamped directly to the body and one at the rear that fits into the front of the cross beam. The torsion bar runs inside the longitudinal tube of control arm. The torsion bar mates with the control arm in the splines at the front of the tube. At the rear, the torsion bar mates with the adjuster, which mounts in the back side of the cross beam.
All these parts are supposed to be concentric where they meet in the cross beam. The rear rubber bushing is responsible for keeping the longitudinal tube centered in it's mounting hole in the cross beam. The adjuster is responsible for keeping the torsion bar centered in the hole where it passes through the cross beam. Since the adjuster is steel and fits without any rubber, the torsion bar will always stay centered in its hole.
The rear rubber bushing, on the other hand, is compressed by the load of the car on the control arm. Over time, the rubber "flows" and sags, allowing the control arm to move upward relative to the cross beam. If it moves up enough, as happened in my car, the longitudinal tube of the control arm will contact the torsion bar. Once that happens, you get wear, a rough(er) ride and lots of squeaking.
I originally thought the squeaking was a bad balljoint, and was planning to do the bushings WIIT ("While I'm In There") only because the front was going to be apart. Turns out to have been a good thing to do.

Bill, there's a guy who might be interested in some of your 2.0L exhaust parts ...
Thank you for the tip, but the parts have already been sold.
