I went in the other day for wheel alignment, and was told I had play in the passenger side of my steering rack. I had a look with the guy, and there is definitely play that appears to be from the rack, and not from the bushings/bearings as I could see the rack arm moving with the wheel. The other side has no play. I've not come across a rack wears on one side only before, so:- Is this common, and is it the rack, or something else? Assuming a rack, can I repair it, or is it new rack time?
