G'day all,
I have a 5m half cabin fibreglass boat on a single axle trailer. I find that the boat/trailer startes to swerve from side to side once I reach around 85km+. I have recently changed the hubs, bearings and springs to try and fix this problem, to no avail. I now suspect that the wheels (9inch) may be the problem. Will bigger wheels stop the swerving? Does anyone have any other suggestions of what the problem could be?
Cheers.
