'89 525 ls clucking sound rear on low speed turns

[Gene in NC]

'89 525a limited slip, 150k has clucking sound rear on low speed turns and less loud occasionally on straight away. Sounds almost like loose lug bolts, but lugs are tight.

get under the car, take the heat shielding off and grab the tailshaft near the centre bearing and give it a shake. is f its loose and makes the twitching/ clucking noise then thats it. Was the same symptoms on mine. hope this helps
