Hi all, my rear derailleur's cage is slow to return back when going towards smaller cogs. In the end, the chain just looses all tension until the cage finally goes back after some time (or if I manually pull it back). It also makes a noise when I pull the cage backwards (squeaky).

First thought it could be the clutch, so removed it from the derailleur. Same behaviour. Seems like there's friction between the cage and the body where the clutch is. Doesn't seem like it's possible to lubricate/grease this part. Any hints or new derailleur needed (it's 2 summers old).

possible that it is the spring inside the derailleur, or an over tightened bolt maybe?

Spray all of the pivot points with grease whilst moving the derailleur back and forth by hand with the clutch off. If that doesn't work it may be that the clutch is so tight that even when it's off it is still on. You can adjust the clutch tension, just Google it and you will find instructions on what to do

Cannot be overtightened at this place, the cage pivots at a lower point than where it is attached to the frame. As I said, I completely removed the clutch system from the derailleur, so it's not the issue.

Anything else I should be checking?

Assume the cable is moving freely and isn't holding the derailleur in a lower gear? Other than that, not sure, other than stripping the cage off and giving everything a good clean and lube, or the spring has lost its effectiveness.

The cage can be removed. Ive had to do this a few times to clean and grease the pivot, not the same derailleur by the way.
I googled "11sp xt rear derailleur diagram" and was able to find the manual explaining the process. I tried posting the link direct, however, I cant figure out how.
