Hub Size

[Jozie & Me]

is there an easy way to determine hub size BEFORE I remove said hub?

I have a pontoon trailer that one hub started pushing grease out and looks to have a little water in it. I want to change it out. I would like to have the part ready to install and not have to go to tractor supply or northern tool covered in grease.

Thoughts?

TIA.

so you're saying a digital caliper is out of the question?

so you're saying you can't read a dial caliper?

good question

yes, I want you to tell me over the internet from 100 miles away which part number I should buy.

If I have to go that route I will. But i thought I would ask the boat gypsies if there was a way to determine before I tear the thing apart.

who made the trailer? Call them with serial number. Then ask to be transferred to their parts dept. Have CC ready. Order said hub, and wait for it to arrive.

That'll be $60 or a few High Lifes out of your cooler.

Most 5 lug are 1 3/8” by 1 1/16” but you won’t know unless you take it apart so quit acting like a dentist and go get dirty.

Ha!

Just go buy the parts in every size. Take back the ones you don't need. Close thread

Tractor supply!

Wish they could all be just the same size.

[Bad Habit]

Wish they could all be a sealed hub without all the bullshit- like a Ford truck hub, I have 32 trailer hubs to deal with.
Even if the bearing in a sealed hub goes bad- you typically get a warning long before it's inoperable- not immediate self destruction from a small pothole.

Most builders use generically sourced parts.

Look for the info sticker on your axle then cross reference online and you may be able to find the size.
Some hubs also have a part number stamped on the back side.

If you do much trailering buy good hubs.

[tsigmon]

You need the whole hub or just bearings and seals? Unless it got really hot you probably only need seals and bearings.

Unless you are really trying to save money it is way easier to just pop a new assembly on.

First world problems when you would rather replace the whole hub instead of 10 minutes to change the bearings and seal.

Not so much first world as my bills don't get paid if my trailer is broken on the side of the road. I also run vortex hubs, not the tractor supply cheapies.
