I had the same problem w/my wife's stock '00. With the wheels facing straight I had no wobble but if I turned tight left or right it wobbled. To discribe the wobble it's like if I had it in 4wd on the asphalt and turned the wheel sharp left or right only not as violent 'bucking'. I checked everything in the front end and couldn't figure out what was causing it. Long story short: I had to replace the front brakes (everything) so I figured I'd change the axle u-joints since they were the originals. When I pulled the axles the u-joints were frozen up so much that I couldn't move them with out putting the axles in a vise. I changed the joints out for new ones and the problem went away. When the wheels were straight I couldn't feel the problem 'cause the u-joints don't move when the axle was straight but when I turned the wheel, the u-joints would bind and I was feeling that 'bucking' until I straighten out the wheel....
Does any of this make sense to you? I'm typing fast so my boss doesn't know I'm doing this instead of working...:eyes:
