eng bay heat would not cause this. & when you turn the st wheel from lock to lock I'm assuming it is tight/binding at some point? I would buy/rent a puller to pull the pitman (its cheap) which would elim the rest of the suspension as the culprit (if it still is acting up) which it is likely the box & it does need to come off for the FSM procedure.
No tightness or binding when checking with h the front wheels off the ground. I'm embarrassed to say I haven't checked for lube yet but will do so this morning. You would think there is no way a guy would assemble it without grease but to eliminate that I will do so today and report back...
