Front wheel humming sound
Posted September 07, 2014 - 05:01 PM
So I have taken the wheel off probably 4 times. I have tried greasing everything up, I've tried different ways of bolting/tightening the front wheel on and maybe this is my issue.
This is my procedure
Put axle through forks, tighten left side fork pinch bolts.... This is the part I'm not sure of. I have tried both ways. Do I tighten the axle nut then tighten right pinch bolts? Or should I do the pinch bolts first then axle nut?
I do believe the sound is coming from the wheel spacer, as the wheel is turning the humming is coming for there. Does the wheel spacer have any movement or should it be tightened down with the axle nut?
I guess it could be something else, but I can only get it to hum on slower stuff and not on a stand.

Hard to say
Try running it dead engine on the street, on a long hill
Wheel setting procedure:
Bike on stand
Install axle with nut no more than 3-4lbs
Insert hex tool inside of axle, and rotate axle and spin the wheel
Keep rotating the axle until you find the spot where the wheel spins the best.
If you are unable to rotate the axle in the clamps, pull it all apart, and inspect the axle for mushrooming/corrosion etc, and repair with scotchbrite, etc.
Grease axle, especially the wide hex part, and re install
Spin the front wheel fast as you can and jam on the front brakes. Several times
This will hopefully set the two fork tubes in parralell with each other
If your wheel or spacer or anything else is suspect, or not stock, do a search in this forum on 'are your forks binding' and follow those recommendations
Now that you believe the forks are set parralell, tighten the left (seated) fork lug clamps.
Spin the wheel again and jam on the brakes again just in case
Now tighten the axle using the hex tool to hold it in place, to 25ftlbs (1/2 spec?)
Now tighten the right (seated) fork clamps.
Now tighten the axle nut to 50 ft lbs (spec?)
Test on the stand for good wheel spin
Test of the stand for good fork action,

Thanks Krannie. I'll be honest I didn't even know there was a hex tool. I always wondered why that axle bolt was shaped like it was. I've been doing all my bikes wrong.
