Very nice truck KDL! If the ATF doesn't work for your wiper try filling up the wiper motor with WD40. Let it sit for a week or so and try it. This is what I did with mine and it works like new!

A safety item that is well worth the effort would be to carry a 4x4x12 wood block with the truck to put between the subframe and bed frame when the bed is up for maintenance.
