    Something that started happening some time ago is when I suddenly accel or lift off the throttle the liberty shifts one way or the other, like the torqueing of the engine is affecting the steering . You can see it turn the steering wheel if I'm not holding it, otherwise you just feel it. It consistently shifts the same direction during accel and the opposite direction when lifting off. It's enough to startle you if you're not ready or used to it. You can't tell it happens if you accel slow but if you let off the throttle suddenly you'll have to make a steering correction to compensate so it's always happening and jeep is always being affected by it regardless of driving style.

    Anybody else experience this and know what the cause is? Going on a trip in a few weeks and would like to fix this before then.

    Thanks.

    It is the rear lower control arms doing it, not the TRI-LINK ( upper )
    The lowers will put you all over the road when on the throttle or letting off
    New lowers and good as new !

    As Tom mentioned time for new rear lower control arms.
    The lower control arms can now move around, when worn or cracked bushings are present in the LCA.
    Check to see if your KJ has had the rear lower controls arms replaced under warranty.
