Have clunking noise in steering column

Explain exactly the meaning of a clunking noise so us Mississippi back yard mechanics can understand the noise. Thanks

I expect the "clunking" isn't coming from the steering column but is a "transfered" noise from a worn steering component. The idler arm is a prime candidate for a clunk. Take it to a mechanic you trust and have the front end checked like tie rod ends, ball joints and shocks. I think that will ilolate your clunk. Don't wait too long, you don't want to loose steering control--It could ruin your whole day.

From a tennessee shade tree mech. I would say idler arm, "Geterdone"

Well the Mississippi oak tree mechanic agrees with vandragon and Geterdone!
