Hi guy anybody have any experience rebuilding the gear assembly in a foul ton trailer jack. When cranking it down last night I found it was frozen, an of course insted of spraying lube on it I forced the handle and I'm pretty sure I broke one of the pins because now the handle moves freely but does not move the jack. Any suggestions would be greatly appreciated. Thanks. Poncho

That's what I would do. I swear those things are designed to fail every couple years. When the trailer is sitting unused, I like to cover the top of the jack with a small plastic pail (actually I cut the top off a 1 quart rectangular oil container and it fits perfectly).

I bet with something more industrial, like the sort of thing one might find on a gooseneck style trailer, you could get a kit. The boat trailer jacks though are throw-aways.

Mostly trailer jacks suck. I often go through 2 a season and my boat lives under a tent where the jack hardly ever gets wet. The problem I've got is ~600 lbs (maybe more, dunno) of tounge weight - seems like not a whole lot in the realm of a jack but anything you can buy off the shelf at West Marine clearly is not intended to hold anything beyond what a 250 lb man could reasonably can lift on their own without the jack.

If the gears don't strip or strip then jam, the pin in the handle breaks.. if that doesn't break something in the swivel does ;).. One big improvement I found was going to a cylinder/pin type swivel mechanism and away from boat trailer jacks (basically has a big pin you pull out completely and 4 holes to allow for 90 degree rotation). These style jacks are safer since there is no way for the swivel mechanism to let go and they hold up better all around.

Buy a new on was my first thought as well but upon further investigation I found the jack was built into the piece containing g the wench. So in order to remove the jack I would have moor the boat somewhere and unbolt the whole unit. I researched the rebuild kit and they are 14 bucks, but I'm just not sure how easy they are to do.

2-3 years max, even when you lube the damn things, like trailer lights.......built to fail.
