Dismantled the winch on the rear deck. It was totally freezed last summer and hardly rotated when I tried to use it. The shaft was oxidated from the drum which caused it. I dismantled the wich, cleaned the parts (quite oxidated) and rebuilt it with no grease since only light oil is recommended. I will dismantle it again when I have the suitable oil. Now the dismantle is easy since I cleaned all the parts.
