Then you’ll loosen off the socket by half a turn and then listen again to hear if the
knocking sound is gone. You may need to fine tune this tightness further but it
normally does the trick.
Scratching or scraping around the spring adjuster
This is likely an over tightened support arm bolt. Take your allen key and tighten
one of the four bolts until it just starts to become firm.
Be very careful to only tighten the bolts until you just meet firm
resistance as you can easily strip the threads if you go too far
Once firm then you loosen the bolt one complete revolution. Now do this to the
other 3 bolts and test to see if the noise is gone.
Scratching or scraping around the gimbal mount
The
bottom attachment bolt
with the spring attached to it is rubbing somewhere.
Firstly, you’ll make sure that the nut on the front side lines up with the end of the
bolt. If not take your socket and allen key and adjust it.
Then take your stabilizer and look thru to that bolt with a light above you so you
can catch the reflection of the bolt. If one side shows the reflected bolt and the
other shows none then you will need to take the Allen key and adjust the bolt so
that the thin sliver of light reflecting of the bolt is close to equal on each side i.e. if
the reflection is on the nut side then you will need to loosen the bolt.
