Stiff Door Hinges

[Trev864]

We have just bought a used van which hasn't had much use this year. The door hinges are very stiff and there seems to be a lot of strain on them when opening and closing the door.

I have tried lots of WD40 and oil but to no avail.

Does anyone else have any ideas please?
