My bike (Rocky Mountain ETSX 70) has been making an annoying squeaking sound for a while. I thought it was just the gear cables making noise but I finally found the source!
The lower shock mount pivot was/is making noise. After freeing the shock from the upper mount, I noticed that the shock did not rotate smoothly around the lower mount. It is pretty tightly held into the mount... nearly bound. I never noticed while riding the bike because there is so much leverage that the bind is basically ignored.
If I loosen the bolt that mounts the shock, the bind/drag goes away, but there is some play in the mount - also the bolt would come loose unless I used some strong loctite. ]
So what should I do? Loosen the bolt ever so slightly (and loctite it)? Lubricate the bolt? Replace the bolt due to it having too much play? Add a washer somewhere?
