    My car jumps on center dividers on freeway, loud. Wheel bearings?

    Lane dividers^^^

    If I go on the freeway and change lanes my drivers side jumps and forces me into the lane. Scary
    Ever since I've bought this car I've been trying to take it on the freeway but its a little dangerous, lol. Cars stay away from me because I'm all over the place.

    new:
    Front strut mounts, struts, outer ball joints, tie rods, m3 CAB's, sway bar end links.
    Rear shock mounts and shocks.

    Haven't changed wheel bearings though because I don't hear any sounds from the wheel. Could this be the first sign of a bad wheel bearing? Or cheap tires?

    And I had a recent alignment. Toe set at +.11 on both sides. Total:.22

    Pull really hard on the top of the wheel and see if you can make the wheel wiggle back and forth. (Hint: You shouldn't be able to)

      I've had that happen when my car was drastically, terribly misaligned. You should get some boards and a pair of tape measures and verify that your alignment is correct.

      theory - someone aligned your car with the front wheels in the air, or set it to toe out instead of toe in

        If I can. What does it mean? (Not saying it does) and while the car's on jacks?

          I'm thinking the same thing. Because I did change my strut mounts after the alignment but did not touch the tie rods at all.
          My car feels pretty straight on the streets, but not to where its perfect.

          Toe in is positive or negative? I forget

            Toe in is where the distance between the tires in the front is narrower than the distance in the rear.

            Worn strut mounts or control arm ball joints are a possible cause for this. So are worn tie rods. Trying to move the wheel while the car is on jack stands will tell you what is loose. If it moves when you grab it top and bottom, its strut mounts and/or ball joints. Side to side is tie rods.

              If you can feel the wheel thunk back and forth, that means something's worn out. You said your suspension is in good shape, so that leaves your wheel bearings.

                This can be caused by asymmetric front camber even when front toe is correct or it can be caused by rear alignment errors. Only front toe is adjustable, but a four wheel alignment will tell if there are other problems from wear or damage.
                The car makes it possible, but the driver makes it happen.

                    Jlevie always with the save.
                    My driver side camber is off only on that side.
                    Car was in accident previous owner. Not sure how bad of accident.
                    -2.6 degrees camber on drivers and -.08 on passenger.
                    I'm guessing my frame is bent.. Found out after I bought the car :(

                    I don't wanna buy a wheel bearing finding out its not the problem and realizing the car is just crap.

                          bad wheel bearings wouldn't do this. get adjustable camber plates, re-zero the car.

                            That's seems to be the only way to fix the camber and hopefully this issue. Wheel bearings didnt seem right to me either.
                            What about steering rack? Probably not huh?

                              You could do this, but it would be a band aid if your frame is tweaked.
