    07 Heritage Softail, a chirping sound is coming from the front fork area when riding over small cracks or bumbs in the road, any ideas what would cause this annoying sound? No other sound except the quick little chirp sound when riding over a crack. Took off the windshield, and the noise is definately from the fork area.
    Thank you

    When you get this little chirp, can you also feel a slight knock from the bars? If so you have a loose nut on the top of the triple tree allowing the top tree to slightly rock on the stem. Harley replaced the old washer, that was bent upward to hold the nut in place, with a thicker/stronger washer so it wouldn't compress and let the top tree rock when hitting bumps. They also increased the torque on the nut from 35ftlbs to 80 ftlbs.

    Unless they have changed the bearing design, the wheel bearings cannot be lubed. They are a sealed permenately lubricated bearing. If they go bad you have to replace them. I doubt this is the case on such a new bike. There is a lot of things on the fork assembly that would cause a noise if loose. Head light or passing light brackets, fork tube pinch bolts, fork tube bolts, nacelle, windscreen docking hardware, fender bolts, caliper bolts, dust shields, just to name a few.

    I would start at the top and work my way down to the axle. Check every fastener.

    Could be the issue

    I tightened everything I could, except the tree nuts, didn't have a large enough wrench yet, but I can only get the noise to occur when riding, so it has nothing to do with the fork or bearings I think. It has something to do with the compression of the tire when I ride. I sat on the bike and bounced it until the handlebars loosened and not a sound out of it, until I get 20 feet on the road to the first crack line. I did take off the windshield and the chipring sound is still there.

    Any other suggestions would be greatly appreciated.

    Anyone in Milwaukee for the 105th?? I live here, so I can't wait to see all of the bikes. I ride into downtown Milwaukee from home for work, saw a nice group of 20 or so coming in this morning.

    It's an 07

    Take it to the dealer let them mess with it shouldn't cost you a dime unless you damaged something.

    The ex had a chirping sound coming from the front of his Road King, and it ended up being a broken motor mount. Your bike seems awful new for that. His is an '03 and it happened last September.

    Thanks for the info

    I have been looking at any little piece in the front end, just amazing the amount of different size nuts and heads there are, no two the same size anyware. The sound is really loud when starting out in the AM and when the bike is cold, the chirp seems to go away after 5 miles of riding, I'll take it into a dealer and let them try to figure out what is going on next week after the 105th ends and they get some sanity back. It is under warranty like what was posted.

    I want to thank everyone for the suggestions, if I ever do find the cause I will post it.

    BTW

    It's not that I didn't want to help but you have a warranty so why waste your time fixing stuff.

    When you are in the dealer get a Service and Parts Manual they are invaluable, will help you with doing your own 5, 10 and 20K+ services with details on what and how things are to be done.

    Parts book will help with getting a part correct with number.

    That noise could be any one of several items

    Loose front axle
    Loose neck bolt
    loose or broken motor mount
    loose exhaust

    Make them go over the whole front end with a fine tooth comb, fix and replace anything needed.

    spend hd's money...

    Front Brake

    I'll be taking it in, but when I was at the 105th and talking to other chapter members, they said to check the front brake. When I went home, I tapped the front brake a few times (wife didn't appreciate it though) and it chirped each time until it warms up, so the possibilities might be a warped rotor. It could be the pads shifted which would not be covered, but nothing I can check unfortunately. i'll update next week after taking it in.

    Hey,
    Just curious what the result was after you took your bike in?
    I'm currently experiencing this exact same issue.
    I have changed my fork oil, checked and greased my wheel bearings, greased my speedo and cable, checked front brake and pads and everything seems ok..
    I did not however replace my fork seals when I did the oil, but they seemed pretty good to me perhaps they could be my issue??
    Anyway, I'd love to hear what the issue ended up being on your end. Thank you
    Kurdt.

    Kurdt the OP might not chime in anymore as this thread was about 9 years now. Try to sit on the bike with the front brake applied and push up and down on the forks to trace the sound. Could be external sheet metal, fork springs/dampening rod, loose caliper. I'll be working on Kawasaki ZX6R soon right after we finished installing stuff we ordered at 4WheelOnline.com for the current the truck project. The previous owner mentioned about the random squeak sound it produces.

    Check your fender for tire burn marks, and make sure eveything on that front end is tight.
