As briefly mentioned, part of the trailer weight is tongue weight, and that should be 10-15% of the total weight. So if your trailer weighs 3500 pounds, you should have 350 pounds on the hitch which means your trailer is actually only carrying 3150 pounds.



ST trailer tires are rated for 65 mph. Spend the money and get the best trailer tires you can get, stay away from the Chinese and Korean imports.



The wiring diagram that is shown with that junction box is wrong, and as stated already, the wiring in the box that you purchased will likely be wrong as well. Iíve worked on, owned, and built countless trailers and Iíve never seen ONE wired the way the above diagram shows. Black-12V+ White-12V- Blue-brakes Yellow-L turn & stop Green-R turn & stop Brown-Running lights Red-center, either auxiliary or most trucks are wired to use that as reverse lights.



When installing the new drum and bearings you need to torque, loosen, then retighten the axle nut for proper bearing seating and so you donít burn your bearings up. Dexter procedure is to torque the nut to 50 ft. Lbs. while slowly turning the hub, then loosen nut and donít turn the hub. Finally, finger tighten the nut until snug, again making sure not to turn the drum.



If you have a grease zerk or what Dexter calls E-Z Lube, only add grease while turning the hub or you risk blowing the seal out.



Take a moment to go over all the wiring on the trailer while youíre working on it. Trailers are the worst wired things there are, and unfortunately there are no regulations for them. You could buy a Chinese fire trap off of eBay and it would be wired better than most trailers on the road.



Thatís all I can think of for now, hope the break install goes well for you.


Thanks for that. Yes I tightened the nut and loosened, then hand tightened to the first hole for the cotter(sp?)pin.


Mike.

You bet! Figured you probably had the job done already but maybe it will help someone that comes across the thread in the future.

The only thing I didn't do that has me a little concerned that you mentioned, is turn the wheel while I was filling the bearings with grease. It does have the EZ Lube hubs and I filled until it was full and coming out the front.

Re: Trailer Overloading


Hmmmm. . . . . Well, hard to say what the outcome was, some guys are fortunate and don’t have any issues, others not so much. I had one guy bring me a trailer for bearing replacement, he told me how he greased it regularly, and to his credit he did, but he never spun the wheel while doing it. I spent hours of time, and countless rags and cans of brake cleaner trying to clean up all the grease that blew past the seals. It was a mess. I don’t want to scare ya, but might be worth taking a peak at them.

I've put about 150 miles on it already without any issue. I've kept an eye on them. There's no grease anywhere it's not supported to be. I suppose if I were going to have an issue I'd probably know by now, yes? Those are freeway miles as well.

Re: Trailer Overloading


Not really. Once the grease gets past the seal and flung onto the shoes there’s no more centrifugal force pushing it out further. The shoes get saturated and basically stop working. The trailer I mentioned earlier had no indication of grease past the seals. Like I said, I don’t want to scare ya, you could be totally fine. If you say they are still grabbing good you’re more than likely fine, just something to keep in mind for the future.

Yep I check how well they grab every time I pull the trailer. If grease was all over the shoes I'd certainly know about it. Brakes don't tend to work well with grease all over them.

Re: Trailer Overloading


If you blew the seal it probably would not have pumped the grease to the outer bearing. I think you'll be fine Mike.

I'm sure there are other things to worry about....

Re: Trailer Overloading


I've never jacked up a trailer to put grease in the bearings so I could spin the wheel.

Spinning the wheel while greasing makes total sense however i can bet that at least 85% of people dont spin the wheel while they grease them.

If they grease them at all........

I grease them every 3 months. I have lost one bearing in 20 years.
