I guess in NASCAR terms, I would say the front tires have too much negative camber. If you look at the truck head-on, where the tires touch the pavement is farther out left/right than the top of the tire. it looks like this /--\ sort of. What would be causing that?

 

swivel *****, wheels bearings wil let it settle a little if they are loose, but the toe setting will cause this a little if it is incorrect. It should be toe out 4mm to no toe. If you are set toe in, it will cause negative camber and wear the inside of your tires.

look at the angle of the swivel ***** when you turn your tire and you will see what I mean.

 

LOL...thank God I'm only into this Disco for $1600! BTW, I think I have a man crush on your 97 Disco!

 

Start with a alignment, they will inspect everything and tell you what the problem is.

 

Another thought is to lift the front off the ground an try to rock the wheel top to bottom with your hands. You may have some good movement and will need to address the bearings and so forth. Like Spike said, the alignment shop wil tell you exactly what is wrong with it, and maybe even notice you need some new tie rod ends as well.

 

Actually get underneath and rock the tie rod ends if the move up and down they are loose and need replacement. oh and check to make sure the bars aren't bent. take a jack and jack up the tires and check for looseness in the bearings.

if everything is good then take it to the alignment shop for a frt wheel alignment.
