The whole front end has been replaced in the last 8 months when I installed my air ride front end, everything from springs to spindles was replaced. I appreciate any advice guys

    Have the alignment REchecked. By a certified truck shop.
    Look for both toe and camber to be out.

    One tire looks like toe wear. Both look like camber wear. Tires leaning.
    Air pressure? Bearings tight. Shocks good.

    I might be wrong in saying this. But is that suspension only 1 spring?
    Wouldn't take much to break 1 spring. And have you sitting on the side of the road.
     
    djb379pete Thanks this.

    I usually run between 95 and 100psi on the steers, and I check my tire psi every week. Thanks for the reply

    That's riverwear. The only way I've been able to make my steer tires on my star wear perfect is to run them at 120 psi.
    I have a air ride front end also.

    Run those tires out and when you put new ones on again, air them up to 120 and keep them there. Trust me. Been there done that.
     
    MM71 and djb379pete Thank this.

    Thanks Swann, I’ll try that. I was worried bout the one spring at first but the 389 with factory air ride only hv one spring so I hv kinda learned to not let it bother me much. I’m extremely particular bout my truck so I go over it every weekend when I’m home hoping to avoid a stranded on the road situation

    I've been battling river wear on my 2012 westernstar since it was new. It has a airtec steer axle . I used to run 100-105 like you also. I've since bumped it up to 120 psi and now they are wearing perfect........ I truly believe a lot wear issues stem from wrong air psi. I've since bumped my drive tires up to max also and noticed near perfect wear.

    I will definitely try that, I usually run 100 to 105 in my drives since they are low pro but I will bump them to max psi this weekend. I will say that I run the bfg 444 on my drives and I get great wear and life from them. I tried Michelin once on my steers and they didn’t wear funny but my truck did not like them, seemed to make the front end feel loose compared to bfg and continental
