54 37 ... Gauging Coupling Fastener (Without Removing and Installing Roof Module)
54 37 ... - Gauging coupling fastener (without removing and installing roof module)
Special tools required:
Important!
To prevent damaging the coupling fastener gauge, set the gauge down only in the transportation crate or on the cross beam.
The coupling fastener gauge is a highly sensitive measuring instrument which reacts even to light impacts with distortion.
The coupling fastener gauge must be checked for dimensional accuracy on a master gauge after being subjected to impact or dropped.
Note:
Gauging of coupling fastener must be checked.
Necessary preliminary tasks:
- Roof module must be installed
- Remove panel for luggage compartment partition
- Remove air outlet grille trim Removing and Installing/Replacing Front Air Outlet Trim Grille
