250 Open diff or lsd.

  1. Hello

    Can someone tell me whether I have an lsd gearbox.

    When the car is jacked up and I turn one wheel by hand, should the other wheel move foward ( same direction) for an lsd?

    If it doesn't turn the same way and turns backwards does that mean it's open diff?

    Thanks
     
  2. Just spin the wheels up in the snow. That’ll tell you

    is your car a cup ???
     
  4. Yes cup

    But I would like to know the above.
     
  5. I don’t think turning the wheels in the air test works for the type off LSD they have. The easiest way to tell is to go and drive it and see if it spins the inside wheel up easily out of corners.
     
  6. If it's definitely a cup, then you have a LSD
     
  7. Pk 18 pk 19

    As said the snow test will give good indication if diff or not. Only real way is look at part number on box which is right pain cause involves taking battery tray out and look down at box for PK4-18. A PK4-19 is non diff
