Is this a job I can do in an hour or two? Or do I need to plan half a day?

Just a little homemade 6' utility cargo trailer I bought several years ago.

Easy. You can buy the whole hub though at northern tool and just slip it on though.

Need to find the right size, put it on and top off the grease.

He is correct. Fix the old hub and use it as a spare.

But redoing the bearings isn't hard and doesn't take very long.

If you do a search and make a phone call or two, I'm sure you can find a place that will repair for you. It should cost much, maybe 100 or so per axle.

It's a pain in the arse to replace the bearingss and races. It's worth the extra coin to buy a whole new hub. Remove the castle nut, pull old hub off, clean spindle, slide new hub on. Took me about 15 minutes.

Get a new one. Have the old one rebuilt and keep as a spare. They are not hard to rebuild if you have the right tools. But it’s probably not worth buying a race removal/seat kit for just 1 hub. Take it to a trailer shop or an auto shop and have them rebuild it.

If there is a trick to the deal, it's getting the nut properly tightened. I do it by ear. I over tighten it a bit while turning, then I back off till it's loose then shoot for the high pitched quiet sweet spot right before it starts to bind when you spin it by hand.

It’s easy and you only need a pair of pliers.

Remove grease cap
Use pliers to remove the pin stuck through the large nut that holds the hub on.
Remove nut. Pull hub off.

Remove bearings and rear oil seal. If the bearings broke and messed up the race (metal rings inside the hub that bearings sit in) you’ll need to tap them out with a hammer and screwdriver and get new ones.
Get tub of grease. Scoop a couple fingers worth of grease and pack it into the bearings filling all crevices. Put bearings in hub. Pack more grease inside the hub. Put on oil seal. Put hub back on and put grease in grease cap and put it on hub

I can replace the bearings and races in the old hub in 15 minutes. Its really not hard. Unless it’s a boat trailer and the races get rusted into place then you’re talking a PITA

Loup is correct. Make sure you clean the spindle as best as possible. Clean it a little longer than you think. That’s a very important step in the process

I've only changed them on boat trailers on the side of the road without the right tools so you're probably right on it not being that hard. I replace my hubs every two years now.

I bought a cheap kit years ago to pull and put the bearing racers back in.

Takes 5 to 10 minutes to pull, grease new bearings, and put rear seal on to rebuild a hub.

Look for a part number on the hub. Otherwise just carry it into a Tractor Supply and match them up.

Got the hub off no problem, gonna go match it up.

Is there any reason to replace the other side at the same time? It's not having issues but just wondered if that would be necessary.
