Default Trailer hub/ bearing help

I am guilty of poor trailer maintenance. I blew a hub on a short drive yesterday. Does it make sens to replace the entire hub, and not just the bearing? I have never really dealt with this before. How do I determine what size hub to buy? I don't even know what other questions to ask.

here are some photos


here is the damaged hub

Here is the undamaged one with details of the tire


I love trying to fix things and learn new systems I just have no experience with this.

Thanks


Any thoughts appreciated

I'd just replace the whole hub. Besides being easier, you will won't have to worry about the old hub being damaged, or your rusted lugs.

A good start is to figure out what the axle weight capacity is, but the sure bet is to measure the bearings/races/spindle.

Start by soaking the lug nuts with PB Blaster or WD40 so you'll be able to get the wheels off. Hopefully the spindle didn't get damaged when the bearings fell apart.

Inspect the spindle carefully for wear before you install new bearings. You will get substantially less bearing life if you mount new bearings on a buggered shaft.

Probably a 5 on 4-1/2 bolt pattern, 3500lb axle, with no brakes. Fairly standard size. I'd buy a complete hub assembly with bearings rather than piecemeal it. As suggested, make sure the spIndle hasn't been damaged.

it looks like a 13" tire based on the tire code....rated for 1360lbs...highly unlikely its a 3500lb axle.

i think the best thing to do is jack up the trailer, and at least pull the hub with the bad bearing....you need to see if the spindle is damaged....if it is, i would just replace the entire axle at that point, as a single unit. if it is not damaged, you now have the hub in hand, and can go to a trailer parts store and ask for a replacement with bearings / race, grease seal, etc (essentially buy two completed bearing kits). However, even though the other side may not have been damaged, it is possible that the lack of maintenance just might warrant replacing the entire axle. you wont know until you pull both sides and inspect the spindles for wear and pitting.. In short, i wouldnt event bother trying to buy any parts without knowing the condition of all the parts.

Judging by the photos, i am betting the leaf springs probably need some attention as well....

For the difference in price between hub and bearings vs bearings only, might as well go with hubs and bearings. Make sure you check the condition of your spindles also. Not too hard to replace. I would highly recommend bearing buddies too. Good maintenance schedule and you'll have peace of mind when trailering.

I just replaced 2 of my 4 hubs and will be doing the same with the other two.

Bingo. Lot of times you cut enough off spindle new hub and bearing won't tighten back up. New axle time.

Something to consider if you have the time/money then:

Buy two hubs and three bearing kits. Do both sides of the axle now. Rebuild the used-good hub with new bearing kit at your leisure and keep it with your truck/trailer for a spare. This assumes the spindles are good, and price point of two hub/bearing sets is economical against an entire new axle.

Up here in Alaska they still want an arm for a hub, and arm and leg for an axle, so I end up getting just the bearing and seal kits more frequently. I'm jealous of the idea that "for a little more" you can just get the hub with race pressed in.

When you take off the hub measure te diameter of the wear sleeve.Your new hub has to fit over that.

That second picture doesn't look right. Hub should be centered in the wheel

Do yourself a big favor. After installation and greasing put the cap back on and get yourself some bearing buddy bras. Put them over the rubber grease cap.
What happens is the grease gets hot and expands and pushes the rubber cap off leaving you with exposed brgs

That's what I have. When I replaced my axle the lowest capacity I could find for a torsion axle conversion that matched my measurements was 3500 and kept the tires from my prior axle. Will upgrade the tires next.

I was hoping to get by with new hubs and bearings. But on closer inspection the spindle is damaged. for $300 pl;us shipping i am getting a new axle, springs /bearings. hubs from the manufacturer. However they wont be here for at least a month. My plan is to buy ONE new hub/ bearing set so I can get the boat back in the water for now. So far so good. I'll update photos once the parts get here. Thanks to everyone who reached out and gave advise. ( Spoke to REGMARINE on the phone)!
