I just got a brand new tandem axle venture for my twenty footer... I must submerge the axles for the boat to go on/off the trailer. When launching the boat, the wheel steamed up as they entered the water...I then notice while driving the trailer around the parking lot to retrieve the boat, that the same wheel seemed to be catching and actually locking up momentarily. Did I warp the wheel assembly?? Are the new trailers suppose to be able to be submerged? When I got the boat on the trailer, all seemed o.k. I am just concerned if I should go back to the dealer about this problem...any ideas???
