I did the steering rack bushing replacement a couple years ago now but recently the steering column got sloppy so I took it apart and did the fix for the tilt ball and the slip joint. The column is nice and tight now and the steering feels like it did after replacing the rack bushings, but the thing is there's still some looseness in the center of the steering, which I noticed back when I did the bushings too. What's weird to me is that in this loose zone, which seems like half an inch either side, it still turns the wheels, so I don't know if that's by design or if there's something to fix. I've double checked the steering rack to make sure the new bushings aren't already bad, and checked to see if there was anything in the suspension that could be clunky, but it all checked out. Also, the steering rack itself was remanufactured a few years ago. I've seen threads about the u-joints in the column behind the firewall but can't find any info on diagnosing it specifically. But I also don't really want to go nuclear trying to get a fraction closer to 100% like new steering. Any advice?
