Marking upper trailing arm

Production seams on the trailing arm can serve as the marking (useful when replacing the trailing arm).
Apply a different marking on the body.
Threaded joints can no longer be adjusted once the work is done as the threaded joints are no longer accessible.

Loosen fastening screws -1- and remove upper trailing arm. Fastening nuts -2- can be accessed from the plenum panel.
