    Are they the same size as what you previously had? If not, might check your ride height. Changing the driveline angle will cause a shaking/vibration too.

    I use to run Hercules AP on my old W-9 and never had an issue with them so I don’t think it’s the tires themselves.

    Steer tires are just whacked from the manufacturer.

    It could be they aren't centered on the rims. That usually takes a bit longer.

    But it sounds like they are just out of round from the get go.

    Steers shouldn't take more than an ounce of weight.

    Get yourself some centramitics.

    Tires from hell.... update.
    I also just changed out my carrier bearing, and the yoke right next to it.
    Been sloppy for a month or so, allowed the driveshaft to slop a little
    tn the rubber, and bearing caps to move end to end in the yoke.
    This will be one less vibration.
    I still have the original tires on the front, with about 1/3 tread, not near wear bars yet, might just leave them on awhile.
    I need to run this truck.
    I don't need the tire drama right now.

    If I put them back on - and it's a goat rodeo;
    you guys will be the first to know.

    Might want to check shackles, and bushings. If you see a air gap in bushing you need new ones. May need to do a axle alignment yearly as well. If your new shocks are bad take them back and tell them you want new ones again. Warranty should be good. And try rear shocks as well.
    I hate roll backs they ride like a front end loader over bumps. So I'd imagine it's tough on you spring ride suspension.
    You must be the poorest roll back operater I've ever heard of. In the states they charge more than a big rig to move vehicles.

    I don't think they are bad, just never saw shocks you could push in
    and pull out so easy. I know they express the rating of shocks
    in a ratio; like 90/10. That's a drag racing shock. It goes out to full
    extension real easy, (the 10 part,) and compresses real hard, (90 part.)
    That puts the front end up in the air, and weight is transferred to the rear wheels. So.... these must be like 50/50.
    I have a 1" impact and a pit, so I checked the shackles,
    and tweaked them all a little to be sure.
    No rear shocks on this 36,000 G.V.W. unit.
    I changed out the springs for a taller stack from a 33,000 G.V.W.
    International box truck; way more give, and bigger load capacity.

    As for your "poor" assessment - I do, what I do - more for fun,
    than to make money. It keeps me sober, and in a little cash.
    What??
    You are right, the two local "Big Guys" charge about triple what I do.

    I am rich in other ways, and can look at myself in the mirror.
    I sleep like a baby cause I didn't rip anyone off today.
    Same with working on the truck. I do everything myself.
    I know it's done right, and I know who to blame if it isn't.
