• Anyone had any experience with bent/ excessive runout in hubs? Loaded /unloaded.
    Changed all my brakes onto immaculate clean hubs in July, car now done 6 k and shakes horrific under high speed braking, isolated it to one front disc with runout caused by rubbing leading to adding pad material and then a little thickness variation.
    So today, new pair of discs, again, had them on a lathe this morning to measure and they are literally perfect, no runout on them.
    Hubs also no detectable runout on the passenger side, and 0.02mm on the drivers side, volvo tolerance is 0.04/5mm
    Drivers side is the problem but doing stuff in pairs to satisfy my ocd.
    All bolted up with shortened wheel bolts in, again, all fine. Passenger side dead straight, drivers side 0.03mm total runout, with 0.05mm permissable.
    However, literally driving down the street, screech of disc rubbing. And again at high speed a slight vibration noticeable (which will obviously get worse again with miles).
    So no play detectable in that hub, but is it possible with the weight of ybr car it's jist enough to push it over that 0.05mm enough to cause immediate issues?
    Discs are not expensive, genuine hubs are, cheap hubs aren't but probably aren't straight either.
    So not sure if bent hub, slight bent and slight play, or just play in bearing enough to cause all this.

  • What volvo is it?

    Have you checked that the caliper carrier is straight and the caliper is working properly? Think that the runout is fine and even getting the disc skimmed won't get the run out any better.
