Knocking
« on: December 03, 2016, 04:33:35 PM »
For some time now I've been getting some knocking from the front right wheel when i hit holes in the road. Does anyone have any idea what might be the problem?

Thank you in advance.

Crazy story... did some riding today, not much, maybe 20km. On the way at my grandads house, while lying on the couch I thought of the knocking, so I posted on the Forum. Got back home (through the fresh snow no one has driven on yet!! Nothing better! ;D) and in the garage bent down to see what could be the cause of this knocking and to my shock I saw this... http://s1036.photobucket.com/user/Tordesil/media/20161204_004909_zpsamsp8ff5.jpg.html?sort=1&o=0

I took my phone out to take this picture and at exactly that moment i got a notification from the forum about a Reply on this thread, about loose bolts ::) I think I've had this problem for a few months now. How is that bolt still there!?!? Not much riding because of school, but still...!? A few more km and... I don't even want to think about what could've happened. Atleast mistakes teach the most, I'll be more careful after this.  :) NOW THAT IS WHAT I CALL LUCK!!  :D

Well, I guess we need to add shock bolts to the list of bolts to check. CFM needs to pay more attention to this stuff.

When you give it a wash, I look at most everything hoping not to find a missing bolt.

Hmmm if that so, then you can add the Allen bolts on front driveshaft (the rear once which are bolted on to gearbox output to the front wheel) and most of the engine mount bolts. I discovered all these while I changed my engine my self last month (was on warranty). I now tightened absolutely all bolts and nuts and screws with Loctite on them.
Just for info :-) 👍

Wow..let's just say.."Check all drive train and suspension related bolts first" the work out from there...

On the survey I mentioned they needed to use locktite on the bolts. They have a tendency to vibrate loose.

I found a loose nut behind the steering wheel LOL.  Sorry I had to.
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.
