groaning..rubbing sound in steering wheel/column??

[barnbiketom]

i'm gettin a sound/feel kinda like a dry rubber groan when turning the wheel ESPECIALLY left, and it's not under the car but rather inside it and I've sprayed lube onto and into the colum at the bottom outside in the engine compartment where the shaft exits and no good. still noise.
any thoughts before i attack this??
25 MPG with the hubs locked in aint too bad huh!!!???!!!
