We found I did not check the tightness of the lug nuts on our trailer yesterday and managed to destroy a wheel, the studs on the hub, probably the bearings, and maybe the axle on the drivers side before we stopped to figure out what "that noise" was. The trailer is unusable because of the damage so the boat on the trailer sits in Lida, Nevada until I can make a repair or, more likely, get the trailer on a trailer, bring it home, and do the work here. I think the Trail-Rite trailer is original to the 1986 Montgomery 15. I am almost certain the inside bearings were destroyed in the carnage and the axle was damaged where the inside seal rides. I admit to having almost no experience working on trailers but think it may make sense for me to plan on replacing the whole axle and hubs assembly, assuming I can get an appropriate quality axle / hub set. Although the first project is to get the boat home, any insights and advice on how to evaluate the damage to the trailer and go about getting parts for it would be greatly appreciated!
