Hi everyone! Hope all is well with you and your motor
I am well but I think something is wrong with Albino.

Problem/issue:

Drive and pull throttle all is good.
When throttle is released, some strange clunk noise is coming from back.

Is it gearbox? I topped up the fluids today and hope that will help.
Could it be the rear axles / lsd?

Going from D to P or R it is very clunky and in P it "rolls" a bit before stopping.

Please help

Have a great day!
