    New steering vibration coincident with new wheel rims

    The ute has just developed a bit of an issue with the steering - at certain speeds the wheel continually "wobbles" back and forth a few cm.

    As this seems to have happened following teh fitting of some Kings rims (16x7) replacing the standard Defender wheel rims, I assume the cause lies there somewhere ?

    The wheels were balanced for me when my old tyres were transferred to the new rims.

    The rims have been fitted to the hubs by hand (eg no rattle gun) so I know I can get them off again.
    I've checked them and they seem fine / uniformly tensioned (ie wheel should be straight not at an angle)..

    Should I get a wheel alignment ? I wouldn't have thought this would be needed just because of new rims...

    Any ideas of what I shoud look at ?

    you might have dropped a weight off the wheel.

    had this happen on a work patrol that i picked up after being used for a 4wd course.

    Are the new rims a different offset? They may be showing up swivel preload issues by putting higher stresses on the steering gear.

    Yeah the offset puts the tyres ever so slightly further outboard. There would only be an inch or so in it though so hardly likely to be enough to affect the geometry to any great extent.

    P.S> What's swivel preload and how does it get sorted ?

    Before you do anything, do not assume because they are new that the new wheels are actually true.
    Get a screwdriver/pointer and clamp it to something maybe 1MM from the edge of each rim then spin the rim slowly and look if the distance changes either laterally or axially.
    Any run out over say 1MM should be investigated.

    Over 11 thousand posts here and you don't know about swivel preload? You must spend all your time in the non technical areas!!

    Sounds like just a balance issue on one of the fronts. I'd take it back and ask them to re-check that they balanced them OK. Had a job as a tyre fitter inbetween high school and uni (along time ago now).

    Sometimes it required breaking the bead and spinning the tyre around on the rim then rebalancing to get them sorted. If the balance of the rim and the tyre happen to both be out on the same side that is.

    My 2 cents, but a cheap (they shouldn't charge you) starting point.

    Yep, my local fella is pretty good but sometimes we need to have two cracks at it to get it right on the car.
    Big wheels/tyres (compared to a car) aren't the easiest things to get balanced.
