I replaced the K member in my Charger about a year and a half ago. The original K was fine. I welded a spare and added a skid plate to it. These changes were made to go along with the torque boxes and frame connectors in the interest of reducing flex in the car.
The car steered harder after the K member swap. The wheel didn't easily return to center after turning and I thought something was amiss. About a month afterwards, I noticed that the steering column collar was off center. The column has some adjustment at the firewall and I had mine out of whack. The inner collar and the outer were in contact, causing resistance. I adjusted it and all if fine now.

Thanks,i will bear that in mind. The bearing is solid on the shaft, what could have caused this ?

I've got the casing off and in front of the locking mech for the ign switch is a tin cup which covers it, then the rear spring clip and in front of that is a small collar before the bearing and it covers the front receiver groove, Should the small collar go on the other side of the bearing to space the press on horn ring away from the ind switch ?
See pic

I have rebuilt the coupler but there is only a very small gap between the coupler and the outer part of the column, it's about 1/2". Does this seem right ?
Bear in mind it's got power steering. I'm also cursing because i put the top section together first and it's difficult to get the cover clipped on, is there a knack to it.
