My left front tire is wearing on the inside 3 inches and has developed ripples (high and low spots every 3-4 inches). The other three are perfect.

What is causing this and how do I fix it?

Thanks!

Well, it could be an alignment issue. (Toe), it could be a worn out ball joint(s), It could be a combo of all this, with a bad shock (thus the cupping) first thing, take it to a reputable alignment shop. Have them inspect the front end for wear, and due an alignment. Then, put the rears on the fron, buy 1 new and put it on the back with the right front on the right rear. You dont mention the mileage. Its definitely a front end alignment/parts issue. (Barring collision/frame damage)

It's most likely going to be your alignment or ball joints as mentioned above, or you will need a camber kit. But either way, take it to a reputable shop that is familiar with your truck. Makes all the difference in the world.

4WD with straight axle?, 4WD w/ independent axles? 2WD? This condition could be caused by several problems, depending on the front end configuration.
