How to Replace a Trailer Hub Quick and Easy 

Thanks for posting! Great step by step video. Pro tip - When reinstalling the castle nut, it's better to tighten the nut firmly with channel locks...this seats the bearings properly inside the hub. Then back the nut back out and hand tighten to where there's no play in the hub.

I never thought about buying a new hub, I always thought I had to replace the bearings and seals. Thanks for the reality check

Nice to see I'm not the only one who does mechanical work wearing flip flops. Proof we live in the South.

I have to pipe in too to say you need to 'seat' the bearings first by tightening up the castle nut (I use a 10 or 12 inch crescent wrench for 'feel') pretty tight (some say 25 ft lbs others 40 ft lbs but you can feel it)while turning the hub, then back it off and then retighten until there is Very little torque on it, then back off so the castle nut lines up with the cotter pin hole in the shaft. Old style round bearings required 'preload'; roller bearings should have zero play after the castle nut is backed counterclockwise snug against the cotter pin. Too much preload type torque on a roller bearing will cause heat failure, and premature bearing failure. I hope I described this so it's easy to follow.

20 ton jack for a kayak trailer... love it! Thanks for the video, I need to do a couple axles.

Thanks for posting. Somehow I didn't know or think you could just get a whole new hub. A few years ago I replaced the bearings in my trailer hubs which was a lot of work and I needed to buy special tools (brass punches and grease packers etc) not including the bearings and then figure out how to do it and hope I did it correctly. This is a much better option for a non mechanic and I now will be purchasing a spare trailer hub to carry with me when towing the trailer for the same reason I carry a spare tire "just in case".

I'm converting from 4 lug to 5 lug hub today, figured I'd re assimilate myself with the configuration of trailer hubs, thanks for the short, quality video

Yes a great easy to follow video. Well done .

Thank you for showing me what I was missing I've watched your video multiple times I appreciate you going step by step thank you

great video. simple and to the point. replacing mine very soon now!

Nice step by step summary! Thank you for the detailed video!

Thanks, dude. This is exactly what I needed.

Great video! You covered everything and didn’t waste any time! Thank you man!

Finally someone not scared to place bottle jack under axle. In the PROPER location. It won’t bend people.

Thanks for posting this great video! Swapping out my hub doesn't seem so overwhelming now! Cheers mate!

Well explained; and nice tool looks like a cordless impact driver

Clear and to the point! Excellent

fantastic content, thank you so much for taking video of this process for us.

Nice walkthrough and convinced me to do it vs taking it to a shop.

Brother that was awesome to watch. There are some people that don't know how to do that. That's a good reminder I need to go check the kayak trailer Wheels since I have plenty of time now. Kayak camping trip got cancelled because of this big East Coast storm. 50 mile an hour winds & heavy rains & floods all day cancel the trip. I was really looking forward to this trip. My Adopted son Paul was going with us & this was going to be his first kayak camping trip for him. Again good video brother. Hope you and your family have a good weekend.

Simple easy to the point great job

Excellent vid. Got right to it.

Great job brother! Thanks for the shout out, lol!

Thank you Sir! My hubby complains hard with any maintenance on the boat or the trailer. This was a huge help. Taking it to the boat mechanic for new hubs would be robbery.

Appreciate the video man!

Thank you .... GREAT VIDEO!!!

Thank you so much for this video. It's very helpful I just recently bought a trailer. The tires are messed up and so is the hub, I kept on looking online where I could find a good video. that would show how to remove Once again thank you so much

Great video, thank you!!

Good job.

Thank you u helped me a lot

awesome video my brother

Thank you sir!

Awesome video, what size tires is that set up?

You need to rotate the hub assembly while adding grease to keep from blowing the rear seal out

Great video man. I don't even need to watch.

great job

What hub did you end up going with? Brand? Great video man!

Nice video !

excellent

Castle nut should be tightened a good bit while rotating the hub. This seats the bearings. Then back off the nut and adjust lightly by hand. Seating the bearings is a very important part of the process. It takes about 30 to 40 foot pounds of torque to get them seated.

Love this video for so many reasons: 1. it's 2 years old and your fingers should just about be clean. 2. you do things like I do > no nonsense< and 3. using basic tools. (except the one to take off the tire). How often would you say they need changing? thank you again

Finally, been looking and looking and looking for the answer. I bought a Harbor Freight video and one of the points is to repack the bearings. But all of the videos nobody showed nor stated about greasing the hub after you put it on. Heck I've even asked a few mechanics hey when I put this hub back on do I need to add more grease and I'd been getting blank stares back. I've been sitting on the damn trailer in my garage since July trying to find "HUB" bearing greasing something actually talked about needing to continue greasing said hub after installation. I hate when I have a feeling that something is missing and you sure enough something was. Or maybe I just found an answer that is convenient to my thoughts. Thanks

Thank you

Good video on hub replacement. I have been doing axle repairs and maintenance for 40 plus years. The dust cap with the rubber insert will leak. I install buddy bearings with 19B covers.

Thanks!

Agreed.. the hub is the way to go over packing bearings

I know Bro but I wouldn't take those lugs off stuff completely like that then jack it up because if the tire shifts under the weight, you could end up with broken studs or worse bent studs or even worse yet the tire falls or POPS out to a knee bar or on your or someone's hand or foot to cause a sprain. Best to just crack those open on a Sure Town Loose but still close to the edge then lift those things up Man. Instead of hitting the hub with a hammer even lightly will dent up the metal, just use a thin Flat Head screw driver at the seam... Cheers !

I lost whole cap assembly, also would need to order these

Good job, definitely a job for rubber gloves.

Nice video!! What size spindle is on your axle and is your hub assembly rated for 2000 or 3500 pounds?

Thank you.

I got a problem with my utility trailer one wheel is sideways but the axle it not bent but the tire does not wiggle to the side what do you recommend to try?

Take it out for a drive, jack it back up and check it again. Good chance it will require tightening since you didn’t torque down the castle nut before backing off and hand-tightening. NBD. Just check it again after a quick drive and you’ll be OK. 😊

Looking for an impact drill. What do you have?

Just wondering if the spindle is bad or wore out is that fixable? Thanks let us know 1🤔🤔🤔🫡🏴‍☠️🙏💚😮🇺🇸🧐✌️

Always replace the cotter pin with a new one.

Thanks

What diameter is your spindle (Shaft) I need to fix my hub assembly and I’m trying to order the right parts

Would've been great to put the part number or the link you bought this one from.

The hub you took off looked ok

Where would I find a hub assembly for trailer ? First time owning and replacing a hub on trailer. Good video thank you and I will subscribe

Thank you, is that a good place to put the jack? I thought it could cause the axle to bend?

Dam man that’s super simple. So buy the prepackaged

Terrific job. The only thing I'd point out is that you spent so much time pumping the jack before it reached the axle. I'm thinking that you aren't aware there is a screw end and you unscrew the round part to just about meet the axle before you start pumping it. This way it's taking the load by the 2nd or 3rd pump.

How do you determine which exact hub assembly fits a particular trailer?

Where you buy that hub assembly at ?

Could you share the hub product, link/name?

Hello great video can I buy that exact hub on Amazon or where can I buy at please provide information Thanks.

What stores sell hub assembly

Any idea where I can get the seal and the cover that your were hammering off while rotating?

Need to check my trailer. Its a little over a year old. Probably needs some grease added too.

How do I order the correct hub for my trailer ? And where are they purchased ?

Where did you buy your prepacked hub?

Are there some trailers that don't have a collar pin?

Where did you get the part?

where did you buy your hub at?

How do you find out what hub to order?

I have play from the new hubs but not the old ones, can’t figure it out

First, never re-use a cotter pin on a trailer. The hub dust covers should also be replaced while you’re there. Cheap insurance. There’s no need to fill that hub with so much grease. The hub came pre-greased/packed. Grease zerks for hubs are a waste because you don’t know how much you’re putting in. Lastly, clean the castle nut and washer of the old used up grease before replacing it so you don’t contaminate the new grease.

Where to get trailer hubs

esay can change it out

Ah

Chock the opposing tire next time! You're lucky it didn't roll around and fall off the jack

My hub and wheel came off a trailer I bought brand new from the dealership. Less then a year old and 1k miles 🤦‍♂️🤦‍♂️

Why wouldn’t you use marine grease on a water trailer smh 🤦‍♂️

Yeah way ro go man , do you recommend putting grease all over the drive way as well , ha ha nice

Informative video, but unsafe. Might think about chocking the wheel on the other side, or hooking the trailer up to a vehicle so it doesn't roll and come off the jack. Or maybe use some jack stands?

Did you just remove lugnuts before jacking it up? lol sketchyyyy

LOL He take lug nuts OFF before putting a jack under the axel.

Nice gloves and sandals while you're eating McDonald's 👎

That's the way to go when you got more money then mechanic skills lmao

I rewatched this and didn't see wear it was ever hooked up to a vehicle to keep it from rolling away 🧐😮🤔🫣😉🙏💚✌️

Thanks!
