crank out windows

[dwinch53]

I have a trailer with one window that cranks out hard..is there a way to lub the thing? thanks

I suppose I'd just shoot a little WD40 in the hole for the crank and turn it back & forth a few times. Also spray some on each joint in the mechanism.

I disagree, WD 40 is not a lubricant primarily, it is a water-displacing formula. It becomes sticky when it dries and just gums up moving parts.Been there, done that.
Sometimes the gearbox must be replaced, sometimes the linkage is binding and must be corrected. The gearbox is lubricated with a heavy white grease, which can become hard over the years. A drop of 3in1 oil on each moving joint is recommended by the mfgr. if it needs lubricated. I have replaced gearboxes and straightened linkage on some of our old trailers. It is not difficult, and replacement parts are readily available online. It is easiest to remove the entire window to replace the gearbox and work on the linkage.
