I have noticed lately that there is a strange type of vibration coming from the front end of my 08 FLHX. I can feel it in the floor boards as well as on the highway pegs mounted on my crashbar. The front tire is new, I had a new front motor mount installed last season(warranty),I am thinking ,wheel bearings? How do I properly "check" the front wheel bearings to determine if this could be the problem? The wheel bearings were also replaced last season, both front and rear. Any Ideas?

 

Simple check for this because it happened to me... look at the mufflers and see if they are centered in the bracket under the bags, if they are up against the bracket because they moved it will vibrate through your floor boards...

Only way to check wheel bearings s pull the wheels and roll them with your finger, if they feel like they are chattering, sloppy or not rolling smoothly, replace them...

 

Another thing it could be is the outside tread on the rear tire. I had a funny vibe when I was turning, especially noticible at lower speeds. I felt it through the floorboards as well. Seems that it was the deeper tread that was left on the outside of the tires. Have a new back tire now, and no more vibe.
