DID YOU KNOW: Advice for the professional

Link stabilizers, where the ball pins are angle-shifted by 150° (only 30° less than a full symmetric part), can easily be inverted during installation i.e. mistaking the L/R fitting position. There is no noticeable abnormal force needed to fit them incorrectly. This error soon leads to a knocking noise, potentially resulting in the ball pin escaping from its housing.



Some link stabilizers can appear to be symmetrical, when in fact they are handed parts with specific left and right fitting positions. Sometimes this is overlooked by installers.




Moog recommends careful checking that each part is the correct one according to the L/R fitting position, prior to installation. An easy way to perform this check is to keep the foreground ball pin in front of you.

  • If the background ball pin is angle-shifted by 150° counter clockwise (like a watch indicating 7 o’clock) the part is ME-LS-5678 and must then be fitted on left hand side.
  • If the background ball pin is angle-shifted by 150° clockwise (like a watch indicating 5 o’clock) the part is ME-LS-5679 and must then be fitted on right hand side.

Another typical example is the link stabilizer for the Audi A6 that must be oriented with the arrow indication on the shock absorber fork.


Any inverted fitment will inevitably cause a premature wear of the bushes.
