The tiny leprechaun tapping at the far end of the steering shaft has been banished. I replaced the upper and lower steering shafts today along with the steering shaft column bearing.
About 5k miles ago I replaced front and rear suspension components and all steering components south of the steering box in search of 'like new' handling.
A tapping sensation remained in the steering wheel that was very slight and sometimes unnoticeable. The 'taps' are now gone and at 168k the steering wheel has very very little play. No plans to adjust the lash in the gearbox, for now.
As was suggested in another thread, the gas pedal assembly was unbolted and set aside before going after the steering shaft bearing. Two extensions and a 10mm socket at the end of a swivel made wrangling the assembly manageable. From what I've read I was fortunate, the bearing came out without a fight. It took more effort to get the new one installed than it did removing the old one.
With no busted knuckles and only one small cut, I am pleased.
There's more to do with the beast as I go bumper to bumper. In the morning my body will tell me how adventurous to be.
