Redact:

Install the new upper hinge (parts 280504, 280549 & 280610 in kit Fig.4) making sure that:
-

New M6 bolts and washers (5000310 & 5001833) are used at the upper (vehicle structure)
mounting points (Fig.4).

New M6 bolts (502622 & 5001833) are used at the door mounting points (Fig.4).

-

A new plastic bushing 284607 is installed at the pivot point (Fig.5).

-

The door is fully supported by the lower hinge and not slightly lifted-up by the lift table so
there is no gap between parts at the lower pivot point (Fig.6).

-

There is no gap between the upper and lower part at the pivot point of the upper hinge
(Fig.7).

-

The four M6 bolts are torqued to 68 lb-in (apply blue Loctite 242 or equivalent medium
strength thread locker on all fastener threads (Fig.8)).
