so, earlier this year, my bb started making a clicking sound about once per rev when I was really hammering it. Now it clicks several times per rev and does it even when I am pedalling lightly. The sound is definitely coming from bb-I don't have derailers and my freewheel is ok. My bike is a 2004 Specialized P Street with (I'd estimate) less than 200 miles. I usually work on my bikes myself (adjust brakes, shifters, replace pads, patch tubes, etc), but never serviced bearings in a bb before. The cranks still spin freely, but I want to fix the noise before things get ugly. Am I looking at bad bearings?

What is a fair price on parts for this job? What is a fair price on labor? Is it something I could do myself? Thanks!

Most bb bearings aren't serviceable, but are you sure it's the bb? Check your pedals, too, they can make similar sounds, as can other parts of your bike. I always have the tools to work on any aspect of my bike, especially the bb/cranks. Sometimes all it takes is a little cleaning and grease (on the threads) and reinstallation to get rid of bb noises.

Check your pedals are in good and tight (15mm spanner, non-drive side is opposite thread) but it sounds more like loose cranks, or crank, than a bearing issue or loose pedals. If you want to do it yourself, get a crank extractor, you local shop will tell you which type you need, pull your cranks, and thoroughly clean the axle ends and axle-holes in your cranks. Then apply a light coat of grease, even vaseline will do, to axle and crank axle-holes. Re-assemble with as much as you can manage on the crank bolts.
Creaks, cracks and groans could be anything, and then some. If it's not your cranks, could be the BB shell is loose (body or left side cup). Then again, it might be your seatpost...
It's basically a process of elimination. Be methodical and you'll figure it. If not, you'll go slowly insane and have dreams about creaks and clicks. Forever.
Peace,
Steve.

You could have:

Shot BB, loose BB, loose cranks.


Usually, throwing some grease on the BB spindle works perfect. I probably need to remove my BB and regrease the threads but I need the tool...

I had the clicks a few days ago as well ,I just tightened up my right crank arm and now all is well. They were pretty tight too, but I gave the allen wrench a tug anyhow and it worked.
