12. How to Check If Your Bearings Are Worn
Did you know that you can check the health of your bearings by listening to your bike seat?
Here’s a handy tip that will help you access whether or not any of your bearings are worn out. You’ll need to have the wheels suspended in the air somehow, using either a repair stand, hanging it from the roof, or by getting a friend to hold it up for you.
You can listen to your bike by pressing your ear up to the front of the seat. It will act as a speaker, amplifying the bike’s internal noises.
Now spin each of your components and listen to the sound. You will hear noise, but it should sound smooth and even. If it sounds loud and/or uneven, it is likely dry or worn out, and your bearings will need either an overhaul or complete replacement.
When checking the bottom bracket bearings, it’s helpful to shift the smallest sprocket and remove the chain to eliminate the noise generated by the chain and chainring.
To hear the rear wheel bearings better, remove the chain from the freewheel by removing and re-installing the wheel, so that you don’t hear the ticking as it spins around.
Since the headset doesn’t spin around as fast, it’s more difficult to hear if it’s worn. Any dryness or wear in the headset bearings will be very obvious, and you’ll feel a notch in the rotation if they’re pitted. Pitting usually occurs when the front wheel is pointing directly forward.
My 2006 Trek 4300 went swimming during hurricane Sandy and many of the components have seized up. The frame is in good shape, but everything else is shot, so I would like to pretty much tear it down an replace every component. I have no doubt that a complete overhaul will easily cost double the bike's value and I have no problem with that. My issue is: I cannot find info regarding what replacement components will fit the bike nor can I find a service manual. Any assistance will be most appreciated.

Newbie here to the forum, but I've diddled around with bicycles since clothes-pinning a playing card to flap the spokes, and that was a long time ago. I'm not specifically a bike nerd or wrencher, except, perhaps, when I need to be. I have tons of experience working with all sorts of materials, machines, and processes, plenty of which translate to things bikes need done to them, so can contribute things to this community from that vantage point...
What brings me to this forum is that I accepted a project from a friend to refurbish his son's KMart quality, 16" mini-BMX bike, so ... Read more >>
Very new to biking.
I have an older work horse road bike and a new to me mountain bike - CCM Nitro XT.
The rear tire on the CCM doesnt seem to be spinning very well. Doesnt coast well, esp. down hill.
I turned both bikes over and spun the back tires with about the same amount of force and the road bike spun for over a minute and the CCM spun for 7 seconds and came to a complete stop.
Any ideas where I should start? Is it possible something is just too tight?

I was recently given a haro backtrail x2 and a lot of the parts are old and rusted so i want to change most of the parts. Its going to be a gift for my little brothers birthday so i only have a couple weeks to get it done(beginning of sept.) Unfortunately im not 100% sure of what im doing. As far as taking things apart and putting them together i think i can figure that out but im having a hard time figuring out what parts to buy. I THINK i know what i need but i dont want to order parts and find out im wrong. He rides in the woods for the most part, jumps some stairs and likes to ride fast so... Read more >>
I could really use some advice with my bicycle problem.
I have a Mongoose Tyax Comp Disc 2010 Mountain Bike that’s literally falling apart.
It needs new chainset (the middle ring is busted), new front derailleur (it’s broken, had to removed it), the rear derailleur is on its last leg and the same can be said about the brakes.
I would like some advice on what parts to buy so they are compatible with each other and the bicycle as I don’t know much about that kind of stuff.
This is the link to the specs of my bike:

I own a Fuji Roubaix and when I pedal, I get the same constant clicking sound as when I am coasting. I have heard that there shouldn't be any sound when pedaling so is there anything wrong with my bike? How should I fix this problem or is this sound normal.... Read more >>
I recently took my bike in because of a knocking sound I have been having from time to time only while pedaling. It is not always constant and can come and go without anything (that I have noticed) triggering it.
I took it into my local bike shop and I ended up spending $100 for everything; got a new chain, had everything cleaned, etc. None of it fixed the problem so I brought it back in to see what they thought. The noise cannot be reproduced unless you're actually on the bike and pedaling. They wanted another $50 for something they said "may or may not" fix the problem... Read more >>
I just took on a project for a sick friend, I want to refurbish his old Schwinn Varsity, Im not to sure of the year, off the top of my head I can say it is a red road bike with the four brake levers and the gear shift is located where the handle bars meet the frame.
So what Id like to do is replace gears, tires, saddle, and brakes, also remove a set of the brake levers.
Any help would be very awesome,
thanks... Read more >>
So I found an old Ross bike, a cruiser, basically in total disrepair. I cleaned and repainted the bike and now I cannot put it back together. Pieces seem to be missing, the handlebars wont go in and stay in, and Im frustrated beyond belief. Any help would be so appreciated. I'll include more details if needed.... Read more >>
Why does my bike make rumbling noises when it is on speed 1 on the front and speed 1 on the back?
I have a GMC Denali 700c road bike and it has 21 speed. It only makes the rumbling sound when I am on speed 1 and 1 on both the front and back. Also, this is only the case when I flip my bike up side down to fix/inspect it. When I am riding it it does not make any noise on that gear and it seems fine. Is this normal? Why exactly is it making that noise? Im afraid I might damage the bike if I just leave it that way and keep riding. Also is there anyway to possibly fix this at home? Please hel... Read more >>
After a year of being outside doing nothing, I would love to use it again.
Its a Hawk Paradise, atleast thats what on the frame. When do you know when biting off more than you should? And hand the bike over to the rag & bone man. I'll be able to post photos tomorrow, when I get the weeds, grime off.
The chain will need to be changed, but how can you tell which to get on the gears, its got upto 3 on the left handle, and upto 6 on the right handle.
I have a basic knowledge of bike maintence thanks to my off-road bike loving ex.

So before I start, understand that I'm new to bike terms and may sound dumb but I need some help!
I recently decided I wanted to buy a bike on Craigslist, it was only $30 (laughs) aand I knew it needed fixing up but after getting it and really looking at it I realize whoever "tried" to fix this bike had no idea what they were doing.
The only identification I have for it is a little duck looking logo sticker thing on the front of the frame that says Raleigh. I found serial number on bottom and one number that was P1013-5. The frame is still in good shape but its been ... Read more >>
Hi guys, I've just joined this forum having browsed here many times before for ideas and information. If I could cut to the chase, I'm the owner of a now-broken commuter/occasional touring bike, ran into the back of a Benz last month and the bike didn't survive.
I'm contemplating new frames to swap parts and rebuild a commuter. In the meantime, I've found an abandoned KHS Winner, looks to be a mid-80's product: its on the heavier side and not an inspiring frame but rides ok...if the sidepull brakes are repaired or replaced. Its 27" rims are steel and degraded and the bars kill my ... Read more >>
Hi i have a touring bike it is well looked after but after a routeen weekly wash that i do on the bike there seems to be a clicking noise everytime the rear wheel rotates fully onece. the noise is louder and more frequent the faster i go
I wondered if there is a simple fix or if anyone could hint to what it is
Thanks if you can
Also all i use for cleaning is soapy water and clean water degreaser and lube... Read more >>
Hi, I know nothing about bikes but recently inherited a harlem toscano mountain bike.
I took it into halfords for a brake & gears service to ensure it was safe to use. They replaced some cables and the break pads, so all good.
I noticed that everytime I went up hill when changing gears the chain would come off. So I took it back and complained and they checked it again and replaced the chain and the back gear cogs. However they said the problem was because its a 6 speed shifter for 7 speed cog. I dont really understand what that means.
There is s... Read more >>
