G'day guys

Having some issues with my spoon 1.5way clutch LSD in a s80 gearbox


Currently gearbox is mated to a b16a2 in an ek4,using all my previous gear that was on the s4c non lsd gearbox (driveshafts,midshaft etc etc)

Now,if I'm driving straight, car is fine, if I do a u turn, after when car straightens out, car feels weird, like the steering wheel just let loose and feels disconnected
While that's all happen, it makes a clunking noise,and whoever is standing outside can see the front wheels moving and shaking

It sounds like someone using a hammer and hitting something metal. Flyid type used is motul FF type2.
Midshaft has no play,axles:driveshafts have play pulling them in and out

It has really baffled me, is this a normal reaction with FWD clutch pack lsd's? As I drive pretty aggressive LSD on car at work and they don't clunk and knock at all

Any input or suggestion would be greatful
