|December 20, 2010 - Time to find out why the steering feels a bit odd.|
It doesn't have much self-centering and almost feels as if there's too much friction in the system somewhere. Step one: lift the front wheels off the ground and get a feel for it. Step two: start removing various components to find the friction. It's 100% Miata steering, so it should work well.
The first thing I pulled off was the steering wheel and compared it to a stock Miata unit. Bingo. Nice and free movement. Wow, that was easy to find. Experimentation with a few other wheels (yes, there are five on the workbench) traced the problem to an adapter that had slightly oversize splines. This let it slide too far down on the column and put a lot of pressure on the turn signal canceling mechanism.
