How to Rebuild and Repair a Wheel Bearing on a Bicycle 

One of the best how-to videos i have ever seen. Clear, concise, nothing left out, nothing overstated. Well done! This will save me at least $20 this week!

The cross sectional drawing made this better than any other tutorial ive seen. Nice work man

Thank you for drawing a diagram! That makes everything so much clearer!

Excellent coverage of how to tighten the locknut, and how tight the cone should be against the ball bearings. That was what I came here for, and I got all the info I needed. Thank you.

Today (with your video help) I switched out a front axle for cost of parts, grease and two new ballbearings (8,70€). THANK YOU SO MUCH.

Great video! I just bought a bike and will be doing the assembly myself for the first time. Your tutorials have given me every confidence that everything will be just fine. Thanks!

Enjoyed your video. Well done. It was easy to watch and not too long. Keep your explanations the same (not too technical) as I for one find some videos overboard technically.

Taken all the fear of this task away - my Brompton bike riding buddy set me this challenge when we were out on the 'big bikes' and he discerned the need to inspect the bearings. My vintage Peugeot has sat in the dining room waiting for the moment when I could pluck up enough courage to start the task. Thanks CJH. BSA

Thank you for this fantastic explanation and diagram of the hub. It really helped me understand what each part is and what how it functions. The description of how to actually do it was superb as well. Thank you very much for your detailed explanation of the process as well. You are awesome!

great tutorial i was changing my axle to a quick release and found your info on the whole tight but not to tight on to allow the wheel to spin really helped me thought i broke my bike lol, thanks bro real good teacher

This is a great video. The detailed description of the hub is very well done.

What a fantastic video.. Well done man! Best explanation seen so far. Thanks for your efforts!! Cheers

Excellent video! You covered all the details so well! If you aren't a teacher by trade, you'd be a great one! Lots of patience, and seeing things from the other guy's point of view! Thanks much!

I watched a lot of you tube vidios on hub repair, and yours was the most informative!

Excellent video, going beyond the call of duty with the diagram. I wish more tutorial videos on YT were like this. thumbs up!

Absolutely excellent tutorial. I fixed my bike thanks to your video and will use what I learned for the rest of my life. Thanks a lot.

This guy is cool I like how he goes into in depth and he how he can see it in his mind like the back of his hand when he was drawing it out on the board.... those wheels are definately from early as the 1990s now upper end roadbike have essentially the same kind of bearings as you would see on skateboards but in different sizes... sweet vid man I know I'm like 8 yrs late

This tutorial was very informative and detailed. More tutorials need to be done like yours. Thank you and I look forward to watching the rest of your tutorials.

Now I finally understand how those hubs work. Thank you for such a great video!

Big THANK YOU! Very useful. The diagram is wonderful. I was smiling at explanations what a "cross-section" is, because I've got used to technical drawings, but I realize that many people can't read diagrams easily.

What a fantastic video! Now I finally understand what the internals of a hub look like, which helps me understand what I need to do to service it. Thanks.

Thank you for making this video. This was the only video I could find that shows how to take apart bolt on wheel hubs.

Excellent tutorial - just the right amount of detail to make it crystal clear.

great video - thanks! Finally someone working on a bike that's not brand new and shiney. Mine never is. :)

This is a really excellent tutorial. You are a natural teacher! Thanks!

Thanks a million, great video and you explain things so well. I now know so much more about bikes than I did 20 mins ago and I have been riding for 30 years!

You have the best bike videos on youtube. I love how you use really simple bikes and explain so well the mechanics, while there is a lot of video out there with top equipments that can't explain simple stuff like this. Keep up the great job

Thanks much. Watched this 5 or 6 times as I completed the relubing! *Very* helpful for me.

Best explanation for repairing/replacing wheel bearings on RU-vid!

Great video - I need to service my rear hub, but i'm a bit of a bike noob and didn't really understand what goes on in there.. now I do so thanks! The diagram was just what I needed. Great work CJ

I love that your ride this POS bike, but keep it so well tuned. I have what i call my trash bike (i found it in the trash), and i love working on it, keeping it in pristine condition, and yet no one would ever steal it. :) Great videos, thanks a lot!

I discovered it was a dust cap with an smaller inner diameter: like a doughnut cut in half sideways. Thanks for getting back to me.

Nice tutorial. I like your inclusion of the helpful diagram in the beginning. Good teacher!

Very clear thank you. I like the fact that you showed the diagram as well as the practical. That helped me understand what it was that I was doing and therefore made the job easier.

Thank you for this instructive video. It's very clear and takes the stress out of dismantling and checking/servicing the hub. I am rejuvenating a bike I haven't ridden for 5 years. Pumped up the tyres and one burst. Replaced it and the next split! And so it goes.

i've been looking all over youtube for videos like this, thank you so much for uploading these educational videos

Something I've found to be helpful, is that after I've greased the bearings and put everything back together I'll tighten the cone to the locknut just snug so that I can nudge the cone to loosen or nudge the locknut to tighten till I get the tension perfect then tighten cone to locknut to set the adjustment. This has worked pretty good.

Very informative. The whiteboard diagram was a nice touch.

Excellent, professional and thorough. Great video

Thank you for such thorough explanation. The cross-section diagram really helped as well.

You are a good teacher.... very well explained....thank you!!

helpful video! i have a newer Schwinn bike and the front tire only spins a couple times before stopping.. definitely going to loosen the cones up and get it to spin better.. feels like i'm dragging a wagon full of bricks when i ride it.

That was very helpful - thank you. Just enough detail without going too far. Top man - thanks for taking the time.

Lifesaver. The diagram was a huge help. Thanks for helping out this budding bike mechanic!

thank you, 11 years ago you made this vide, 2023 and it helped me - history is important - thank you again :)

Excellent video. Your explanations are clear and I learned a lot! Thanks.

This is a great video! Thanks for the clear, detailed instructions!

I tried to install a quick release system onto a bike it was too small for and had balll bearings everywhere, i was so stressed about it and this taught me exactly how to solve that problem!! I guess you can learn anything on RU-vid!!

Thank you for the awesome video buddy! It definitely taught me what I need to do a solid job on this. Keep it up!

excellent demonstration thank you very much for taking time and effort to help some one in need,i did all steps and fixed my bike .keep posting good stuff

Great video. Makes next week's task a lot easier. Thanks.

Thanks very much, this helped me understand how the wheel works and how to fix it. Great presentation and attention to detail! I appreciate it.

This video helped me Soo much and my bike is now running 100% thank you :)

You made this messy process perfectly clear. I applied it right away. Thank you !

Thanks for sharing this. It is very easy to understand. Well done!!!

So thats why my bearings kept getting loose and ripping in half! Thanks for the excellent video!

Good instruction video. I had done this while ago not knowing what I was doing. If I had watched this before, it could have saved me a lot of time.

I SO appreciate what a careful and caring teacher you are in your videos! Thanks for such a comprehensive, yet easy to understand, explanation of wheel bearings. VERY helpful, and I will quickly be putting this new knowledge to use. …and you’ve EARNED a new Subscriber, my Friend!

Thanks..very nice explanation on cycle bearing operation and how cycle wheel rotates on bearings smoothly. you are very good at explaining things.

A decade later and this video is still helping people. Thanks!

Dude. Your the Man. I was lost on what to do. . my first mechanic job. You were so helpful. Two thumbs up for you

Thank you, just nice to watch someone that knows what they're doing to double check my own work :)

This is the best video on ball bearings and greasing them.

Wow. Very nice video. What i liked is that you used for your video a real wheel instead a fancy new wheel and hub like other guys. Thanks for this beautiful tutorial.

Excellent video cj. Wish I had watched it before taking my road bike wheel apart!

Awesome Chris, great vid. Just fixed my hub on mountain bike. Came out great. Perfect tips and great explanation. Very much appreciate your taking the time. Craig

THE BEST EXPLAINING VIDEO ON RU-vid ON THIS TOPIC!!! thx this vid helped me a lot!

you are such a great teacher bro your videos are the best about bicycles on youtube :D i learn a lot everytime

Thanks for being very informative, which you take step by step of what tools are used.

Thanks for the video. Thus has been really informative. I am going to try this with my rear shaky wheels

Text book. If you cant sort your bearings after watching this, then give up. Great vid!!!!!

Thanks for the explanations. Enjoyed the video a lot!

Thanks for this very educational video. Very good drawing.

Thank you so much for making this, it is so helpful.

Thanks a lot man this helped me to figure out what my problem with my bike was, it sounds horrible so probably is kinda rusty inside i hope that i won´t be needing to replace the whole thing thanks again! God bless you!

Best video tutorial on how to clean out the front wheel ball bearings. Great explanation and to the point. Wish you could have cover the rear bearings and explain how everything works, but hopefully on your next video. Thank you for taking the time to post this video. Learned a lot today.

Excellent video! Great closeups. Very helpful. Thanks! :)

Big thanks, very VERY informative and instructional. Exactly what i was looking for to tweak my bearings. Thanks so much.

I'm teaching myself bicycle mechanics so i really appreciate this. 👍👍👍

Great video!!! One of the best presentations I've ever seen. You knocked it out of the park!

Thanks for this video. It helped me with the back wheel on my son's bike. The back wheel on the Schwinn bike was a little more complicated but I figured it out.

Finally got around to doing it. I tightened it up, worked like a charm. Thanks!!

helped me out alot! was wondering why the back wheel was so hard to turn, now i know

Great video! Ridden over 50k miles and yet didn't have a very clear picture of how this worked nor how to make a repair. Will try this out on my noisy front wheel this weekend!

You are a great teacher.

My bicycle need to repair now. And that's video really help me. Thanks for shearing.

Great job. This helped me save an old bike

Excellent video! Clear, focused, covers the topic. Great job

Great tutorial, just successfully cleaned and re-greased the bearings in my hub. Thanks for the video.

This guy is awesome. Very informative, great vid man.

Man, thank you for ur video, it's really helpful,please keep it on.

Nicely done! Today I took a hub apart and to my surprise.....bearings all over! (I'm a noob) Then the moment of "what did I do??" After your vid, I'm confident I can get it back together and running freely again, which was my intent to begin with. Thanks for you concise and clear instruction!

that was a good explanation of how the bearings work. I find it alot easier to adjust the bearings by using two cone and adjustable spanners at the same time, if there's too much play you carefully turn both lock nuts clockwise simultaneously and if its binding you carefully turn both cones anticlockwise simultaneously, so long as both sides start out moderately tight repeating the adjustment two or three times torques it up sufficiently enough. I've not come across anybody else that does it this way but if you haven't already tried it I've always found it to be less frustrating and more precise.

WOW, with this great video, I might be able to do the job myself. Very helpful! THANKS

Excellent video. Exactly what I needed. Thanks.

Great! very clear and helpful! Thanks for sharing.

A superb video, many thanks for this.

very nicely explained!!! no time wasted thanx keep em coming.

Hey cj. Really appreciate your videos man! Very informative and helpful.
