Removing Upper Trailing Arm

→ Wear personal protective gear.

→ Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).

Information 

If the upper trailing arm is to be used again, mark its position with respect to the body -arrows-  using a felt-tip pen for example (assembly aid).

• Production seams on the trailing arm can serve as the marking (useful when replacing the trailing arm). 
• Apply a different marking on the body.
