>>>Huh? The spindle doesn't connect to the shaft; the spindle is the
suspension piece that goes between the upper and lower control arms, and mounts
the wheel hub.

I suspect that you're actually talking about the pinion (half of the 'rack
and pinion'). The splined shaft which sticks up out of the steering rack
housing and connects to the splined coupler on the steering shaft, which in
turn leads up to the steering wheel, is the end of the pinion gear.

>>>The steering wheel can turn a million revolutions in each direction
before the shaft is connected to the pinion. What you need to do is to center
the rack, and center the wheel, before joining the rack pinion to the shaft
coupler. Center the wheel, then jam something between the bottom of the
wheel and the seat, to keep the wheel from moving.
Turn the rack all the way to one end by hand. Then slowly turn it all the
way to the other side, counting revolutions. You'll come up with 3 1/4 if
my memory serves. Divide that by two, and you get 1 5/8. Turn the rack
back 1 5/8 turns, and now it's centered, and ready to be connected to the
steering shaft.

>>>They do. There is a pinch bolt which clamps the splined coupler onto
the splined portion of the pinion. There is a circumferential groove
machined into the pinion, through which the pinch bolt passes. So you have to
slide the splined coupler down far enough until the pinch bolt will pass
through the hole in the coupler, and through that machined groove. The end of
the coupler will be just about at the end of the splines on the pinion gear
at that point.
What was the resolution of your steering rack issue? Did you get your old
rack back, or a different one?
