Steer axle

[dhirocz]

Do you have an adjustable FW? Also, does it do this with certain tanks or all of them?

I noticed my yard sometimes has different tanks with the plate located in slightly different positions.

Have you checked your ride height recently?

What brand of tire do you run and have you checked the alignment recently? Are they wearing down or cupping or...?

Some tires you'd be lucky to get 200k out of. A different set might get you close to 500k. I put on Michelin steers with centramatics and have had no complaints for either wear or ride quality. Additional weight might be a factor, but so is alignment, tire quality, balance, tire pressure, etc...
