16. How to Replace a Freehub Body
Demonstrates how to remove and install a cassette freehub body. Requires a hub overhaul.
If your cassette cluster is loose or gets stiff you may need to replace your freehub body. To do this you’ll need a 10mm allen key, and you’ll have to first remove your cassette, axle and bearings as demonstrated in previous tutorials.
Once your cassette and bearings are removed, slide the 10mm allen key into the center of the hub, and loosen it by turning counter-clockwise. If the freehub is very tight and difficult to loosen you can get more leverage by mounting the allen key in a vice clamp and sliding the wheel down onto it. Then you can loosen the freehub by turning the wheel counter-clockwise.
Once the freehub body is removed, clean the hub surface and bolt and grease all the way around the bolt’s threads before re-installing.
Gently thread the new freehub body onto the hub splines and thread the bolt back into the hub. Using the allen key, torque the bolt to approximately 45Nm, or about 400 inch pounds.
I have an Avaya 27" wheel. On one side of the hub, the bearings were pushed out.
I purchased a new set of bearings for both sides (the kind that come in a casing, not loose), greased everything up and made thumb tight. One side, I couldn't even tighten/loosen, which wasn't an issue.
Maybe a month later, both sides are now pushed out, the bearings/casing is bent, making it unable to put the seal back on, and the wheel wobbles probably within 1/2" each way. I obviously made a mistake somewhere, but I'm not sure where.... possibilities:

Is it possible to go from 7 to 10 on the rear wheel. The bike is a schwinn sidewinder sold at walmart. I think it is a freewheel. It's a pretty decent bike, it get's me around without costing too much.
if it is going to cost more than the bike is worth, than I will live with 7 on the back, but the rear gear needs to be replaced one way or the other. I would like to go to 10, but not if it will cost alot of money.
I am mechanically inclined and will do the work myself, but if the more experienced of you could point the way, that would be great.

I've been having a terrible time trying to remove a very old Regina America Freewheel. I purchased a Park FR4 remover from a local bike shop. However, the tool would not fit over the ridged round "nut" on the outside of the wheel. A tech at the shop indicated that I should try to "tap" the "nut" in to access the freewheel locking nut. I gave it quite a few "taps" (actually, hard raps) with no success. I tried using a vise to press on it, also with no success. I'm trying to replace a broken spoke on the freewheel side of the wheel and have been off the bike for 2 weeks... Read more >>

I've got an older set of 700 wheels that should be replaced with a set I picked up recently. The problem is that the newer set has a 135mm rear dropout spacing axle and the old set is 126mm, which fits my older road bike frame. The newer set has a 9 speed cassette and the older is a 7 speed cassette.
Can I change the axle in the newer set to fit my older frame and will the older 7 speed cassette work fine or do I need to change the cassette freewheel??... or if there is a better way... ?
Thanks !... Read more >>
Hi there, I just wanted to know if you all use a spoke tensioning meter (park tool TM-1) when tensioning your spokes, or if there was another way of doing it without one as they are quite pricey for a bit of plastic! I wondered whether you just guess within reason or go by feel? thanks... Read more >>
I've just noticed my front wheel is not centred within my front fork and is off to the left, which is causing the right v-brake caliper to lean over towards the left also. How can I fix this? I've tried taking it off and rebolting it back in, but it just goes back to the same position. Thanks for any help!... Read more >>
I have had built a custom rear rim which uses a Novatec D042 hub. I received the rim back via courier yesterday, fitted the tube and tyre on and mounted it back on the frame (a Specialized Cross Trail Sport Disc hybrid).
When I turn the pedals with the bike on the maintenance stand and then stop turning, simulating freewheeling down a hill for example, the hub doesnt freewheel, it keeps turning the pedals like it was a fixed gear bike.
I know the obvious answer is to go back to the guy who built the rim (and who also put the disc brake and cogs back on the new rim for me) but he is... Read more >>
I have an old road bike with very narrow tires. I plan to use this as a commuter bike, so I'd like to swap out to thicker tires, something like the Schwalbe Marathons. The wheel size currently is 700c.
The issue that I have is that the fork crown is very close to the current narrow tire. I've attached a picture. The only option I can think of is that I need to get a slightly smaller wheel and also possibly new brakes with long-reach.
I wondered if anybody has suggestions or other ideas.

I have a 1998 GT Palomar and I put new wheels on it about 3 years ago and it was serviced just a couple of weeks ago. Anyway, after the service the back wheel has been spinning freely. However, I picked up a puncture and removed the wheel and sorted the puncture, but when I put the wheel back on and tighten the nuts the wheel only spins for about 1/10th as long as it was just before. I am completely stumped, could anyone help?

I just mated a 7 speed wheel with my old 10 speed and have noticed that the freewheel is wobbling in driven mode only...not so much when coasting. Ideas?

I broke two spokes and resolved to fix them myself.
I removed the cassette on the wheel, removed the broken spokes, thread the new spokes through the hub and the other spokes, but I cannot get the new spokes to screw into the old nipples. Or, rather, I can get them started, but there is a point past which my spoke wrench will not turn.
I am starting to think that I need to replace the old nipple with the new nipple that came with the new spoke.
Now that I type it out it seems obvious, but is this right? New spokes will not always go into old nipple?

Hello, I just would like to know if it's possible to put 26' hybrid wheels onto a mountain bike frame? and also if you take a look at the picture of this bike frame, whether or not the back end would be compatible with quick release as it's an old frame. The front should be as I've brought new forks for it, thanks. Daniel... Read more >>
this is a complete noob question i know, but please bear with me!
My front wheel had a bit of play so i did a bit of reading, took it off and tightened the cone nuts. Once i did this the hub turned freely and there was pretty much the same amount of axle showing at each side. the thing is, there is only enough axle to go about half way through the drop out. the way i see it, the axle cannot go all the way to the outside of the drop out, otherwise there will be no room for the springs to compress on the quick release skewer, but only about half the thickness of the drop out...

I don't know if I am doing this procedure whole wrong, but when I try to tighten my back tire, the nuts just keep spinning and not tightening. I made sure to hold the opposite still screw it in, but the nuts just spin rather than tighten. Is it something wrong with my bike or are the nuts faulty?... Read more >>
