Over November and December as pasrt of the winterisation of the caravan, I normally lubricate the Milenco wheelclamps, leg locks and hitchlock with WD 40. This year I also have one of the blue through nthe wheel locks supplied with nmy Elddis. (Similar to the Alko through the wheel lock). Personally I hate using it as it is a pain to get on and off, but I am getting concerned that if it jams on during the winter months, I may have trouble getting it off. It has two ball bearings that protrude when locked, is there any sort of lubricant that i should use on this type of lock?

Also is it a good idea to also lubricate the whole mechanism that goes within the cylinder or just the ball bearings and the key entry point? 

Thanks

Have you considered trying spray grease? Otherwise I'd just get some grease and grease everything well by hand, that'll stop it jamming over the winter.

During my engineering days I was always warned of using vaseline as its ingredients can react with certain seals and plastics and can cause more harm than if left alone. I believe the same goes for WD40 or should I say engineers perfume.
