bearing between shift tube and steering shaft needed

air chisel to the pin holding the ujoint to the steering shaft to get it out more then one time...using the delrin as leverage to push against. the downward hammering force....equals wobbled out. it's more of an oval now then it is a circle. i should have supported the steering shaft from below while air chiseling out that pin. a bushing would probably do the same thing. a bearing is probably the better choice....that or getting to a point where i can stop having to take that damn pin out. i mean technically its still operational as is....but i have it out again and thought i might as well try to fix it. had to take it off to get the header off, so i could get the head off the motor.
