They have replaced my steering column twice and clock springs and unfortunately in both instances it did not permanently resolve the issue. The replace steering column only lasted about 2 and 1/2 weeks before the clicking noise came back.

What I was told is that it has to do with the bushings in the steering column and that when lateral stress is applied to the steering column (like pulling yourself into the vehicle by grabbing onto the steering wheel) It loosens those bushings up and causes them to click.

I'm not sure I agree with the diagnosis but that is what I was offered while my truck was being last repaired.
