My right front tire is wearing the outside shoulder substantially worse than the rest of the tires. I've replaced the trackbar, had the front end aligned, and had all the tires balanced and rotated. I lifted the front end and tried to find play in the wheel bearings by grip the wheel/tire and trying to find play. No dice.... I can feel a "clunk" in the front-end from time to time when I'm coming to a stop, but can't trace it back anywhere. I'm lost..... Can anyone give any ideas?

 

Dude, this is a guess, but look and make sure your right front shock or spring is not bent and binding up. They should have caught this when they aligned it, but maybe not. If your truck rises over a bump,and the spring or shock binds and won't come back down to standard ride height, it pulls the bottom of the wheel in. which would cause your wear problem on the outside of the tire. The "clunk" you hear when stopping could be the bind releasing itsself.

 

Wow......no body else? Is everyone else as stumped as I am?[]

 

Strange I have the same thing happening to my van but its the drivers side. I Checked and did eveything that you did and still seems to be off. I dont have a clunk when stoping though just a slight niose when truning right at speed.

 

I'm also having this problem I asked over on pavement sucks and it seems like a lot of the guys with lifted Dodge Ram 1500's are having this problem and no one knows what it is.

 

Back to my original statement: The outsides of the tires are wearing more due to a: over agressive driving (sharp turns at consistently high speeds) or b: the bottom of the wheel is pulled in farther than the top, causing the tire to ride on it's outside shoulder. As the suspension rides up and down over bumps and waves in the road, the camber angle changes. Say you have a 90-10 shock on the front (drag racers) The body of the truck would lift up under acelleration (or a bump) and the shock will keep it up there for a long time. (the 90 side) In a drag car this is ok. In a passenger vehicle, you want a 50-50 shock to maintain proper ride height and alignment. If your truck suspension is too stiff, or has a binding problem trying to re-center itself at 50-50, it will not allow the camber to zero itself back out after the bump, causing the camber angle to increase and wear the outside of the tire. If it was binding coming back up - you would wear the inside of the tire out faster.
