To start, I have a 1998 f150 4x4....In the last couple days I noticed that I could feel a slight wobble in the steering wheel, which got progressively worse. Took the truck into the shop and looked over the front end. Noticed that the tie rod ends on the driver side were bad so I replaced them. Checked passenger side and they seemed fine. Drove truck around today and I can still feel a slight wobble, not as bad as it was before the new tie rod ends but still present. When i try to wiggle the passenger side tire around I get a very small amount of movement with my hands at the 9 and 3 o'clock position. No movement at 12 and 6, and no movement at all on the driver side. Any ideas? No clunking or humming/grinding while driving. Just a slight wobble.
