Just re-read both the installation and service manual. I did not see the mention the blocks on the chain ends needed to be in any certain position, however, it makes sense they need to be vertical so they do not hit each other when they pass.
Mine makes a single pop when it is ??90% extended. Looking at the cable blocks they are no where close to each other when the noise occurs, however the cables are tighter than the instructions seem to indicate they should be.
It only pops on deployment after traveling. If retracted and extended while parked it never makes a noise.
Since I have no leaks and it only does it every now and then, maybe leave well enough alone.
