Don, et al:
Taking your second question first: The cottor bolts are indeed threaded so
that when tightened, they will wedge the king pin into the eye of the axle.
Recently I found I could wiggle the front wheel on my TC (same as P or N)
and found it was not the usual worn bushings in the spindle or bad wheel
bearings, but rather the cotter bolt had bottomed out on the head and not
wedged the king pin completely. When I removed the bolt, it showed marks on
the flat wedge indicating movement of the king pin.
I measured two sets of cotter bolts at a hair over 2". These are
replacements that do not have the original large hex head. I won't use them
because the large bolt head is what actually limits steering travel. One of
the bolts securing the backing plate should come into contact with this
large head of the cotter bolt. Without that limitation, steering travel
will continue until the peg in the steering box reaches the end of the worm.
If this happens, you put severe additional load on the sector shaft and they
can break at the most inoportune moment.
So if you still have your original large headed cotter bolts, use them. I
cured my problem by cutting a small shim to fit the flat of the wedge bolt
and reinstalled. All looseness was eliminated and the car steers like a
dream.
