Dually Front Tire wear

[shorthorn]

Hey guys...

On my 14 dually, I had the toe set to the 1/64" spec as per I had seen on this site when I had my new Cooper AT3's installed. That worked great to eliminate the wear on the outside edge of the tire.

Now, the truck is at 60K miles, roughly 20K on the tires and I am seeing bad "chopping" on the fronts, which is far worse on the left front. I have been running a Ranch hand front bumper since last December. Tires are always maintained at 80 PSI.

This chopping is all the way across the tire... Looks like one tread block is ground off, the next one is fine, next one ground off and so on...

Wondering if maybe the factory shocks can't handle the weight of the ranch hand? Or maybe they are just shot? Perhaps balljoints? I have never seen this "chopping" this bad... being one tire makes me think possibly something is worn out.

You can check the balljoints your self by lifting the front tires off the ground and rocking the tires back and forth to check for play. I'm guessing its the RanchHand weight. I had a Reunel winch bumper on my 2nd gen and it caused lot's of premature wear on the suspension and steering.

Probably has nothing to do with your issue but rotate fronts side to side at 15K and keep tire rotation the same. That means breaking the tires off the rims.

I am due for a rotation almost... about 12k or so since last... I get what your saying... makes since... but wouldn't I get the same putting the fronts on the outer dual and move the outer dual to the front? That is how I have done in the past.

Seriously wondering if the extra weight of the bumper is causing the tire to "bounce" due to not enough dampening from the factory shocks...

I never touch the rear tires. They wear very evenly.

When not towing I lower the tears to 35 psi.

If what your referring to as chopping is the same as cupping, it is this is usually a sign of bad shocks or tire balancing issues, or a combination of both, not typically an alignment or balljoint issue. Being one tire would lead me to lean towards a balancing issue however it is entirely possible for a single shock to go bad.

Mine had a bad left front shock at 12k miles. Oil leaked out on my clean driveway so that is how I noticed it. Warranty only replaced the bad one but better than nothing.

Since the op already fixed his alignment issue I would assume a bad shock. Throw on a set of Bilstein 4600 stock ride yellow n blue or 5100 stock to 2'lift silver n black. They don't have a shock for the factory rear air ride.

Precisely what I stated in my post already

I know, I was agreeing with you.
