I have a 06 XLT SuperCab 5.4 auto 41K miles. When I'm stopped or going slow and try to turn the steering wheel it gets hard, then easy, then hard, then easy to turn. When I'm on the highway it is smooth (I suspect I'm not turning it as far). No leaks, no noises, no apparent damage when viewed on the rack. When you move a tire when the truck is on the rack you can also feel the hard, easy, hard. After reading on the forum I suspect it might be one of the joints in the steering rod, it symptoms seem to sych with each turn of the "u-joint" on the steering rod. I plan on pulling that first and checking it and if it's not that I guess the steering rack would be next? How do you pull the steering rod? Any suggestions or hints before I dive into this? Am I headed in the right direction? Thanks for any help.
