DID YOU KNOW: ADVICE FOR THE PROFESSIONAL

MOOG REFERENCE:

CI-BJ-16641

APPLICATIONS:

• CITROËN Jumpy/Spacetourer (04/2016 -->),
• PEUGEOT Expert/Traveller (04/2016 -->),
• OPEL Vivaro/Zafira Life (03/2019 -->),
• TOYOTA Proace (02/2016 -->)
  

PROBLEM DESCRIPTION

Ball joints of this type have a large collar above the ball joint thread which the installer must ‘punch’ with a flat chisel. This action locks the collar into a locating notch on the wheel knuckle to prevent detachment.

This locking method is a proven solution for many vehicle applications. However, it is still possible for detachment to occur, and instances have been reported both in OE and Aftermarket fitments for the vehicles indicated.

SOLUTION
 

To overcome this issue, MOOG recommends the fitment of CI-BJ-16641 and careful adherence to the following installation steps:

In many cases, ball joints which are screwed on to the wheel knuckle have no counter nut to prevent accidental detachment. Such detachment can result from normal vibrations when a vehicle is in operation.
