I think your problem lies in the way the stage is limited upwards. On top of the stage, right behind it where it slides against the arm, there should be a little screw. This screw limits the movement of the stage to a certain point upwards. If the limit exceeds the adjustment gear and its opposing track, then the stage just goes up one notch and then it clunks down. If you screw it down the stage is limited further down, if you screw it up it's limited a bit higher. The point of this screw is to prevent objective and slide damage. Try adjusting this little screw a bit further down and see if it still 'clunks' when you turn it up. After that we may work on properly adjusting it. If not, please post again with whatever detail you can provide to aid you with this problem further.

There is a bulletin (E31529192) that describes your exact problem and recommends replacing the screws with new different screws to prevent this from happening again. The front section around the lens assembly is only held by 3 screws so access isn't a big deal, just be careful if you try this because there is a cable connected to the microphone that is easy to damage. The new screws are part number 3-056-559-01. Be sure to rate this solution. Thanks!

This is a very common problem. It sometimes happens without cause, sometimes by tightening or removing a filter. There are a couple of keys that keep the front lens from rotating while zooming that are very thin and easily bent. They have to be removed and straightened, and the rear piece you see floating has to be reinserted. It's about a $40 job and half-an-hour by a local independent repair shop. Expect to pay Nikon twice that.

The zoom creep is an easy fix for Canon. I really do not recommend trying to tighten it yourself, since that would void your warranty.
It is usually free to tighten the zoom ring.

Those small plastig bungs do come out, you will need a fine probe to prise them out then you will see 2 philips head screws which hold it all together, not sure how you will tighten your shaft though, looks like it might be moulded into the plastic retainer, good luck! on mine the motor bearings are seized,
