Strange because no one seems to have to use shims.
The sound isnt whistling really i cant explain it. At the same time as the LSD install i fixed a broken vacuum line to the exhaust flap. But today i heard that the flap is creating all kinds of strange of noises. It rattles at idle and reving it almost whistles. Could be that creating the nolse. Because before i fixed the line. That little flap made the whole convertible rattle like something was loose..
You're right, whistling isn't really the sound I would describe it as if it were truly a backlash issue. It's more of a whine than whistle.

But noise coming from exhaust flap wouldn't happen from backlash issue. You said you heard whistling only on deceleration, and I'm assuming you mean gas off pedal not brakes being applied. Me thinks backlash too tight...

Just curious what gear oil did you use?
