Diff shudder??

[vicszd30]

Howdy all, I have what I think is a diff shudder and was wanting to ask what options I have in fixing this issue..
All comments welcome and if someone has a stick of tnt I think I know where I would put it
I'm guessing locker but what is there for the 03 zd 30? cheers vic

How long has it been since the oil has been changed in the diff and when does it make the shudder?

What sort of lift have you got? pretty jacked up? how is the angle of pinion in relation to tail shaft, maybe take it to a suspension expert and see if caster wedges will help you out.
