Service bulletin LI46.80-P-079280

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Detach underfloor paneling under rear axle steering. 2. Remove heat shield. 3. Remove large clamps from left bellows. 4. Open small clamps on left using a suitable tool and slide to side. 5. Slide bellows to side. 6. A second person sits in the veh. and steers with activated drive, automatic transmission in N position, to left limit stop. Careful! Risk of entrapment when steering at the same time! Do not move steering wheel during operation steps 7 and 8! 7. Clean screw-on stud of any grease using a clean, lint-free rag. => Up to the area where the stud enters the bearing! Then completely remove grease from screw-on stud with a lint-free rag soaked in safety cleaner (A 000 986 56 01). => Up to the area where the stud enters the bearing! Important: The surface must be entirely clean and free of grease! 8. Then apply Hylomar (A 001 989 25 20 09) all around the degreased screw-on stud using a clean brush. => Up to the area where the stud enters the bearing! 9.
