This is my first post for a long time .... which in a way is a good thing as it means nowt has gone wrong with my van

Anyway, the sliding door seams to have developed a screeching noise when opened/closed .... i assume it just needs greasing/oiling ...?
Also, how often do you need to get them wax-oiled underneath, mine was done when i bought it (4 yrs ago).
Thanks
