If you can assess the damage...see if the axle stub is OK, or not. Meaning the stub axle that takes the bearings that the hub turns on. You'd need to pull off the wheel and the hub and all the old grease to see it. The end will look similar to the bright metal shiny parts of this: https://www.couplemate.com.au/wp-content/uploads/2017/02/1.8TDEX.jpg ...except if yours is damaged then some of the nice smooth surfaces in the above pic will not be so nice and smooth. Gouges, scoring, dents, etc. not good. If the axle stub is not damaged then you just need bearings. RV/trailer shops will have those and if you bring in the trashed ones they can see the numbers and get you replacements. Otherwise you'll have to get the numbers yourself off the old bearings and order online. If the stub axle is damaged then yeah you need a new stub axle...what that means depends on how your trailer is put together, I'm not familiar with what you have. Some are in multiple parts, and you could replace one side stub axle. Others, it's all one piece of metal with stub axles on each end and you'll have to replace the entire axle beam. Then there's the hub - for the studs that hold the wheel on, usually those can be replaced by a shop if the hub itself is not busted up or bent and the bearing races on the inside are not damaged. Same as for stub axle above, you'd need to get it apart and the bearings out and look at the races inside the hub. I almost did something like this the first year I had my M17...but I only got a mile or two heading thru town at low speed before I heard "that noise," so no damage done. Hope the fix is not too difficult! cheers, John On 5/28/21 6:51 AM, David Grah via montgomery_boats wrote:
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!
