How To Fix Loose Wobbly Wheel Hub

How To Fix Loose Wobbly Wheel Hub

I show how to repair a bike wheel with a loose hub that wobbles. I disassemble, the hub, clean, lubricate, and reassemble the bub with new bearings. After the overhaul, the wheel spun smooth with no wobble in the hub. The bike is a 2010 Specialized Hardrock.

Most front hubs use ten 3/16″ balls on each side; Most rear hubs use nine 1/4″ on each side.


👍 And please give my video a thumbs up 👍

    thank you for all these details through the process, like checking for tightness! this is super helpful 🙂

    What is the proper name of that ruler for measuring the bearings

  6. flamehairdisaster1 on July 20, 2022 at 11:14 pm

    So incredibly helpful. Thank you!

    Man i wish this guy was my neighbor

    Thanks for this great video. Question: why is it important for the quick release lever to go on the non-drive side of the front wheel?

    Hello, I know this is not the best videoto ask, but I’ve seen in the past your videos, a lot! and now I couldn’t find the more appropriate. my question is: could you go from a Shimano TA hub to a QR? considering we have 2 hubs could we swap the axle in order to have a "new" hub made by the TA hub + the axle from the qr hub?. I saw the overhaul for the shimano different freewheel body and I found it very helpful and technically amazing. Thank you for your reply and for sharing your experience.

  12. MaxximusD on July 20, 2022 at 11:21 pm

    I have both new and old bikes. I am extremely grateful for these valuable skills in repairing older bikes, this helps me so much. You are a very valuable addition to the biking community. Thank you.

    Why when tightening the cone I can’t get it smooth, only rough whether looser or tighter? What could be causing that please.

  14. Pat Del et Fan on July 20, 2022 at 11:21 pm

    it is so complicated. i aheve my back wheel loose same problem but i cannot do this. why they make it so complicated?

  15. BuDDaH MAyNe on July 20, 2022 at 11:22 pm

    Doing this right now on my motor bike.. it was in need of a overhaul.. 🚲💨

  16. Derek Kinnish on July 20, 2022 at 11:23 pm

    Thanks your videos have really helped me out 👍

    This is the most heartbreaking thing for me. Because, I like leaving and going to the big roads that my state has. my hub can be worn after a few weeks. If a car just needs an oil change then a bicycle should just need it’s chain cleaned then lubricated. I can’t believe my bicycle is 2 weeks old and has a broken hub which makes me broke, and now having to go on foot ,which makes things just horribly slow. I like traveling around town and the.only thing I want to think about is having air and lubricanting the chain.

  18. ITHz on July 20, 2022 at 11:28 pm

    Hello RJ,could you make a video on a wobbly wheel with a freewheel type hub?

  19. Wy Hunter on July 20, 2022 at 11:28 pm

    Seems you out dust cap backwards, good video though.

  20. Bryant Schubert on July 20, 2022 at 11:29 pm

    Note to myself: 3:39 Fails to show the part where all the bearing fall on the floor. Don’t bother watching the rest – don’t trust.

  24. CurtiMongous on July 20, 2022 at 11:37 pm

    Someone help I did everything in this video BUT I went to place the wheel back on and it wouldnt tighten all the way without the wheel being tight

  25. Lily Mitchell on July 20, 2022 at 11:38 pm

    My rear wheel hub is wobbly but I can’t undo the axle nUts to do anything to it

  26. Andrew Singleton on July 20, 2022 at 11:39 pm

    Considering I’m about to do a one year servicing on my bike. This is real good to know. Thank you for the video

  27. CrazyPancake on July 20, 2022 at 11:40 pm

    the bearings on my bike was change because it has play and then my bearings was change and after some time it starting to wobbling again how to fix?

  28. oneby on July 20, 2022 at 11:40 pm

    hey RJ, is it possible to replace loose bearings with caged bearings? If yes, is there any disadvantages of using caged bearings instead?

  29. NOMAN IN GIRO on July 20, 2022 at 11:40 pm

    I bought a bicycle and couldn’t install the front wheel. I messed up in the hub. I hope i get it fixed tomorrow

  30. Jon. Ward on July 20, 2022 at 11:42 pm

    helpful thankyou!

  31. peruRail on July 20, 2022 at 11:42 pm

    nice work!

  32. Cam on July 20, 2022 at 11:42 pm

    The cups in the wheel I’m working on are damaged but not replaceable. I replaced only the ball bearings and left the damaged cups and the wheel is completely silent now. It may only last a year, but this repair is cheaper and easier than rebuilding the wheel with a new hub.

  33. Adam Kostan on July 20, 2022 at 11:43 pm

    Nice vid

  34. BluxeEdits on July 20, 2022 at 11:45 pm

    Planning to do this cuz my wheels are wobbling i’m beggining to think it’s the bearing thanks for this video!

  35. quantum Q on July 20, 2022 at 11:45 pm

    Thank you

  36. Anthony Eadie, Jr. on July 20, 2022 at 11:47 pm

    Thank you! This is just what I needed! My rare hub was doing the same thing!

  37. Brett Yasu on July 20, 2022 at 11:48 pm

    Thanks RJ! Clear and concise. Easy viewing as well to see what you’re doing and no random stories that make the video 2 hours long! Thanks! Subscribed!

  38. Lewis Maynard on July 20, 2022 at 11:52 pm

    Top video my man. I learned a lot. Thanks for your step by step simple instructions. Top man. 👍

  39. dest 123 on July 20, 2022 at 11:52 pm

    I wouldn’t worry about magnetizing the bearings, that effect won’t last too long as that is completely not how magnets are made. Temporary effect. Nice work/commentary btw.

  40. Simon Powell on July 20, 2022 at 11:52 pm

    Little tip: getting that fine adjustment between cone and balls can be tricky. Over tighten cone a touch. Put lock nut behind it and back off the cone, not tighten the lock nut usually a much quicker job.

  41. Dinaltium on July 20, 2022 at 11:56 pm

    Can you use Vaseline as a greaser

  42. Jason C. on July 20, 2022 at 11:57 pm

    The hub on my bicycle wheels had ceramic ball bearings so they fell
    right out. I only had to tip the wheel over after taking out the cup. A
    couple where still stuck in the hub though. There was some grease
    holding them down in place. I got them out with a set of tweezers. The
    ceramic ball bearings is the new thing now. Supposedly the
    ceramic ball bearings are more round, smoother, and have a lower
    friction resistance. I did check the size of them so I can get a new
    set. I didn’t have the special park tool though so I used the screw/drill
    gauge that I already had. I just put the ball bearing in whichever hole it fitted in. It
    looks like they are 1/4". Nevertheless, I did get the hub overhauled.
    After I got it all back together I thought I did it wrong But after
    watching your video it looks like I did it exactly as you did. Which
    is a relief because now I wont have to take it all back apart again and
    redo it all. Thanks RJ. 😀

    i have had a bad wheel wobble on the rear wheel of my bike for a while now, i’ve replaced the whole drivetrain with a new one but it’s still there, now i know how to fix it though by watching your informative video, thanks so much, i’m subscribed to your channel my good friend ! ! ! ! ! 😉 lol

  44. DM18 on July 21, 2022 at 12:00 am

    Thanks for this video. Really helpful.

    Just out of interest – what would cause the hub to become loose like that? Could it just be age?

    I’ve recently started taking my mountain bike out again on trails – with some bumps but nothing major.

    It was in a garage for over ten years – before I dug it out and replaced the chain/ cassette/ crank, tires etc. but I never got new wheels.

    Would you say that’s my answer? Just want to ensure it’s nothing I’m doing wrong etc.

    The mic is highly sensitive, it’s picking up on whatever your sucking on, not really into weird fetish.

  48. Jimmy Men on July 21, 2022 at 12:06 am

    thanks for making this video it really helped me do some maintenance work!

  49. Trevor Holbrook on July 21, 2022 at 12:08 am

    Hi RJ, would you agree with Park Tools, that when adjusting a hub bearing that is on a quick release axle, that the cone nut should be tightened, then back off a 1/4 turn so there is very slight movement of the bearing, which makes allowing for the flexibility of the hollow tube axle. The bearings Will then tighten up when the axle is in the dropouts using the quick release nuts.
    Looks like I should have read ChuckD59’s comments first , as he has said the same thing.

  50. Hans Wurst on July 21, 2022 at 12:08 am

    Perfectly eyplained and showed how to fix such issue. Thanks.
