Hi all, I have a '09 FXD and just started hearing a knocking type sound in the front end when riding over rough road surface or bumps. It sounds almost like struts bottoming out, but I know that is not the case. Any thoughts?
Thank you.

 

Steering head bearings probably need adjusted or the tank bolts may be loose.

 

Thank you ackman, I will look into both suggestions.

 

Any time, how many miles you have on the bike?

 

Lousy stock fork oil. I had the same problem and changed to the next grade up....I think it was Screaming Eagle Heavy Duty, and that fixed it plus got rid of the front end dipping so much under braking.

 

2900 fun miles : )

 

i had the same problem with fork oil, i put new inverted forks on my FXDX, every bump sounded horrible, and the forks were hangin up .... Putting in the correct amount, aswell as the right kind, fixed it no problem... rides like a dream...let me know

 

Might even want to check your pinch bolt, axle and caliper bolts torque values.

 

Thx again guys. With all the advice, I am confident that I will get rid of it.

 

I'd have the tank bolts checked and the steering bearings checked.
