There's a recently developed knock coming from the rear right side. It is more of a single "tock", which is barely audible. In its intensity, it resembles the usual noise of the gear selector when brake pedal is pressed while in neutral, or less than that.
This "tock" can be heard on a hard left turning from stationary and just before stopping on hard deceleration. But only sometimes and as said, it's barely discernible to the untrained ear.
I've noticed some small cracks in the rubber of the rear subframe bushes but nothing else out of the ordinary. Drop links, like everything else, look and feel pretty solid, too. I will be replacing the subframe bushes in fall anyway but does this ring any bells as to what else should I be looking into?

PS: The entire front suspension has been replaced less than 5 months ago so not likely to be confusing with something coming from the front end.

Upper or lower hub bushes which are enclosed heim joints are another thing to check, they fail and knock...  Pete

Thanks Pete, noted. That would make sense as any developing play would be longitudinal

Buy genuine joints there are some awful cheap ones out there that only last about 6 months...  Pete

You're right. No point replacing them now and having to do them again in six months time!! I used Lemförder, which btw were the priciest, for the front suspension.
Although the car is practically free of rust underneath, removing the bushes was a royal pita which took me and my buddy a whole day.
I'm therefore planning a trip to the stealers for my next service and rear bushes.
No mate's rates of course, but there are a few other things I wish to do as well, like getting a copy of the service book and switching on the front PDC. I might ask them to do a diff and transfer case oil change if they're not too greedy.

When I did the rears on my old fatty had to use an HGV 3/4 drive rattle gun to undo the bolts, it snapped two of them... they are about 15mm so a right PITA...

Wouldn't like to do it on the drive...  Pete

I know exactly what you mean. Had I known how hard the ball joints and bushes were to remove I would have opted for complete assemblies instead and saved me a day. All this on a practically rust free car! Lesson learned.
I'll leave this one to the stealers so they can waste their time.
