Clunking during decel in heavy rain

[TheBoomSpoon]

I have a quaife lsd in my 7at. About a year since install, seen a few track days, etc. During heavy rain only and not even during each heavy rain but sometimes when slowing down as it gets under 25 or so a horrible clanking will be audible that slows as speed decreases. Tranny feels normal, never ever heard in non-heavy rain.

Also have whiteline front and rear sways lowered on swift spec r springs.
Less than 5 times i've ever heard it. Also, when engaging to park to reverse or into drive initially there is a harmless sounding click. I thought maybe i didn't notice before because of music turned up which is possible but could this click just be the lsd and the clunk in the heavy rain described above, anyone hear of that symptom before?

Thanks
