Left Rear Suspension Odd Noise

[mcmike27]

To all, recently we had our stock 98 986 in for service after I discovered a 'clunk' sound coming from the left rear. Upon inspection the dealer found the source of the noise. The half shaft bolts were not torqued down to sepc and when the car was not under drive 'load' they would shift and then under load they would bang on the bolts and the 'clunk' could be heard. Once properly torqued down they noise vanished. We recently started to AX the car and I noticed this past week when I was under the car trying to sort a almost but not quite similar noise that the left rear sway bar was not the same distance as the right rear sway bar as it relates to the alignment panel in the rear. The right passenger looks to be normal but the left side has 'sagged' a bit. It is now ever so slightly touching the alignment plate. When I drift in 1st gear and bump the gas or from a dead stop turn left I can hear a distinct small 'click' almost like metal on metal noise. I pulled the LR tire and everything else seems to be in good working order. The left side of the car does 'sag' a bit.

Any ideas here gang as to the difference in the sway bar gap or the 'click' sound? Could it be a falling shock, worn spring? Both are still original to the car. It has 91k miles to date.

Any help or guidance is greatly appreciated.

Tks
