Article [13] ST1300 - Flange Bearing Inspection

Re: Checking your Flange Drive Bearings

Forgot to mention. Thanks again Chuck! Another job well done!! We will miss you! When you move to Colorado.
 
What are the noticeable symptoms of this flange bearing that would prompt you to inspect them? After my last tire change, i now notice a low-pitched humming sound when coming to a slow roll and stop. Thanks!

You should inspect them at each tire change. You may just have a very slight notchy feeling and that's enough to replace them. If your tire-guy isn't doing this, take the wheel off yourself and check. They are fairly easy to replace:

better make sure its not your back brake pads dragging... they make a hum sound as well !

As a matter of fact, when I had my tires replaced they also put new rear brake pads in. The braking seems to work okay, but there may be something related to that work that is producing this low-pitched hum when coming to a slow-roll stop. The mechanic did take it for a test ride after I complained about this, but he was wearing a full faced helmet and may not have heard what I was hearing. I use a flip-up helmet and can hear the sound easily with the helmet in the up position. Weird...
 
I know this is a very old thread but since it is in the Article section I would like to inquire about the pictures. They seem to be missing these days. Can someone relink those pictures please.
 
Why do you need to remove the flange just to inspect them? I stick my finger in the flange side while on the rim and can spin and feel the bearings. What is the difference?
Thanks for the help.

You don't necessarily have to remove the flange. I do like you do. If anything unusual is felt then remove and check to figure out where the bad bearing is located.
 
You will remove the flange every time after the first time you remove the collar and find bits and pieces of the inner flange bearing under the collar. The collar rides inside both bearings and the inner one is usually the one that comes apart. Turning the collar from the outside it still feels good because the outer bearing supports the collar after the inner one disintegrates.
 
hi guys, I just removed my rear wheel to replace the tire. Noticed the flange has some play inside the rim. Is that normal ?
will check the bearings when I get the wheels back from the tire shop.. Just wanted to know if I need to worry about something bad ?
 
I believe what you are talking about is normal. The flange is held by the big o-ring on the outside and the rubber cushions on the inside, so that if you grab the splines and apply side pressure it will move against the rubber cushions.

This is an old thread, but when I was going through the maintenance on my '06 last summer, I felt the same thing. Igofar recommended replacing the dampers in the hub, and that tightened things up significantly. They're inexpensive and a quick and easy replacement.
