Sharan Squeeking juddering grinding noise steering wheel Steering going?

I don't have the answer,,,my Stratus 2001 just started doing the same thing, only it's more like a popping/cracking sound when steering wheel turned to the far right or left. Took it to repair shop after work today; mechanic drove it and reported that it sounds to him like a spring or bolt is either coming loose inside the column or already has. I have an appt to bring it in to disassemble the steering column this weekend to find the solution to the problem.
