This trailer jack and wheel
This trailer jack and wheel combination are well made, but not well thought out. It seems as if the end user has become victim to the engineer who doesn't really use the equipment that they design. The grease point is on the inside of the jack facing the plate, which becomes a stop point for the extension. A picture shows how it impacts the plate causing chipped paint, and thus rust. The 90 degree rotation pin is held in place by a locking pin, which is extremely difficult to remove. This locking pin should have been a spring loaded locking pin, much like the locking pin to adjust the height of the arm. I was missing a locking pin for the wheel, which I had to wait over a week to get replaced. Lastly, my boat trailer tongue is 3 inches wide and the bolts supplied were 6 inches long with threads only on the end, forcing the use of many washers to allow the jack to be tightened onto the boat frame. My solution was to go buy 4 inch stainless steel bolts to fix this issue. Just bought them, still needs installed. Threads all the way down the 6 inch bolt would have fixed this issue from the manufacturer. A unit with this price tag could have had better engineering, appropriate parts, all of the parts, and faster shipping. I'm keeping it, but I would not buy this product again.
