I had some steering questions the other day. Marty pointed me in the right direction. My problem was the draglink was too short thus pulling the steering wheel to the left. Fixed now.

Steering wheel - it should be centered (flat) when the steering box is centered (the marker between the indicator bumps on the steering box). your front wheels should then have the tracking set with (from memory as to what Smiler told me) 5-15 minutes of toe-out. (0.6-1.8mm).
Once that is set and the steering box is known to be aligned with the steering wheel, you can then adjust the drag link from the box to the LH hub to make sure the steering box is centralised with the (now aligned) front wheels.
If the steering box isn't centered when the wheels are aligned, then you'll probably end up with it constantly drifitng, or having to apply more than normal steering correction when driving.
You shouldn't just take the steering wheel off and re-align it to center, as it a)won't have had any effect on the alignment, and b) can damage the rotary coupler, as that then won't be centered when the steering wheel is. RAVE specifies that the steering wheel can only be adjusted 1-2 splines MAX - if it's further out than that to the center of steering box etc, then you need to undo the lower steering rod and align THAT to the steering box by centering the steering box, and steering wheel and reconnecting it.

Assuming the tracking of the front wheels was set correctly by the previous owner - or whoever they took it to to be done, and is within the tolerances specified in the work shop manual, then the issue of the steering wheel center would either be in the connection between the steering box and the LH front wheel on the drag link (as the track rod will be holding the wheels at the correct value, and as the vehicle drives in a straight line, they find their centre point, and the adjustment of the rod to the steering box is a bit short, thus pulling the steering wheel to the left ). Or the steering wheel may at some point have been taken off and turned to line it up center (before the vehicle was re-tracked). Or the steering wheel is centered to the steering box still, and the drag link needs adjusting to get the steering box and wheel back to center.
The easiest way to see whether it's the steering box/wheel or drag link is to stop with the steering wheel centered, and check to see if the steering box is centered. If it is, then with the steering lock off (Ign pos 1) adjust the drag link so the steering wheel is centered.
If the steering box isn't centered when the wheel it, then that alignment is out, and will need to be corrected. once the steering wheel and the steering box line up - then check to make sure the steering box is central when the vehicle's front wheels are centered.
