It depends what you mean by 'have to hold the wheel'. If you mean the car
drifts to the left unless you manually turn the wheel to the right to
compensate that is a difference in suspension alignment between the two
sides. It's not toe as many think, with everything else equal that just
causes both wheels to turn in or out by the same amount and the car still
goes straight. It's primarily the castor angle that gives the
self-centering action of car steering, and if one side has more caster than
the other that wheel will tend to go straighter, pulling the other one
across, so you drift to the side that has the straight wheel. Other
suspension and rear axle alignment factors can also cause pulling to one
side or the other.
But if you mean the car travels in a straight line on a flat and level road,
but the steering wheel is off to the right, that is just the position of the
wheel on the column splines, or the track-rods have been set up incorrectly,
or both. The track rods should be set such that the wheels turn the same
amount from straight ahead each side. The easiest way to check that is to
mark the top centre of the wheel with tape when the car is going straight,
then turn the wheel from lock to lock (easier with the front jacked up).
Your mark should be at the same angle to the vertical each side on full
lock, if it is more one side than the other then the track rods are out, so
adjust both track rods by the same amount but in *opposite* directions (to
keep the toe) to get the wheel angles the same. If the wheel turns more to
the right, then you need to screw the right-hand track rod into the
track-rod end (to pull that wheel in) and the left-hand out to get it
balanced. Once you have that right now see where your wheel is pointing
when you are going straight ahead, and adjust on the column splines
accordingly. That is only a step-change of course, so may be off slightly
one way on one spline and the other way on the next, so tweak the track rods
again to get it spot-on. Then it would probably be best to get a tracking
alignment done, making sure that they adjust both track rods by the same
amount (but this time in the *same* directions) to keep the rack and wheel
alignment.
Indicator cancelling is simply a matter of sliding the clip around the
column until it is between the two switch fingers, pointing at the switch,
with the wheel in the straight-ahead position. That is for the later
collapsible and full energy absorbing columns at least. The earlier solid
columns have a screwed peg in a fixed position so the column shaft has to be
turned in the UJ (or the UJ on the rack shaft according to which has the
bolt groove going all the way round the shaft) until the peg is at the right
angle. The 77 and later wheels and switches are self-adjusting as the
cancelling arrangement is on the wheel itself.
