Knocking noise from LSD after FD swap

It needs to go back to the shop ASAP. Something was put back together wrong. Stop driving it and get it back to the shop immediately. Hopefully it can be fixed without replacing any major assemblies. You might need to buy a replacement/aftermarket LSD if that is broken. As it is, it could lock up at any time with no warning. This is serious. Get it back to the shop.

Thank you
The noise removed after changing the oil with right gear oil from toyota service. (Toyota 75w-85 LSD part number 08885-02606)
Now my diff is Completley silent .

Thank guys for care

Only our Cusco makes noise.
