    I've been in business since '99 and been a member of lawnsite for almost two years. But I must admit, I've never seen a thread or have a reason/solution for the annoying front wheel wobble on some ztr's.

    Is there a solution to this problem? What good is the "Super" in SuperZ if both front wheels start wobbling like crazy when you get up to about 2/3 full speed? :confused:

    Only time I have seen it is traveling across asphalt or concrete, on the WB's too as well.

    If the setup on the bearings has a nut, try tightening it up a bit. If it is a c clip, try adding more grease. Sometimes, the bushings on the top and bottom are worn. What brand specifically?

    They make a locking washer for that caster nut. Ask PJ for the part number or just ask your dealer. Cured mine right up.

    I see that wobble also.......I assume it is due to one of the front tires being out of balance..like real bad. Ever notice when you are on flat surface how bumby the back wheels are...On a scag WB I put in new bearings and those bearing for the yoke and that didn't affect anything in a positive way.

    my old bobcat ZTR did that real bad on the road going fast so we just slowed down a bit. i woudlnt let it keep doign it, it will wear bearings and bushings faster

    Dealer told me it is due to 1 front fork being a littile higher than the other. If you have an adjustment to lower the offending wheel, it should correct it.

    Drop the tire pressure.

    You need to replace all the bushings in the casters and velke (hitch, and trailing arm) every year or two, don't forget any under the deck such as if you have spring-loaded belt tensioners riding on an arm.
