cleaned & replaced parts... still noise

Coxy_UK

I've never experienced the clicking noise like my bike has now before. I have cleaned, greased torqued the stem etc, replaced top and bottom headset bearing, but to no avail.

It's not your normal clicks, it's far beyond that. When I use the front brake it is very loud and fast as the front is under load. I have investigated the brake etc, but the noise definitely appears from the steering components. I can't find any damage either.

Open to any suggestions now please.

Could be the forks? You don't happen to have a Marzocchi forks do you? I've seen some of the older ones get a cracking sound/click where the crown is attached to the stanchions.

If not, could be a bushing issue or similar in the forks.

Hi no I have Fox Float 32 forks.

I'm not sure how I check if is bushings or not? No noise is made on the work stand,, only when riding and with weight on the bars.

I bet it's the csu. Turn bike upside down, take wheel out and rock the legs fore and aft independently. I bet it's replicated by doing this.

The good news is mojo will replace them under warranty (subject to inspection) bad news is, depending on how old they are, they'll charge you the price of a full service

What is the CSU please? I had these forks converted from Talas to Float not so long ago and that included an upper service.

CSU=Crown Stanchion Unit:



So pretty much what i was referring to in my first post about the Marzocchis. Possible slight movement between the black part (crown) and the gold tubes (stanchions) in the picture above.
