ZILL4R

hi guys ok so i decided to do a bit more investigation on this so i got in the car with a mate and took it for a drive and after giving it a hit a few times to warm up the diff and gear box we went to a empty industrial road and started to turn the car. I steped outside to see if it woul lok up but all i saw was that the when you stop the car and take off and turn it shudders but the rear and front wheels move normal. I have been advised that because i have a jim berry Full monty that the clutch is a Brass button and when it heats up on the fly it tends to shudder I am lost now guys not to sure what it could be is there any ideas ?

Hi all I need your help? Just recently every time i turn my 32gtr 1989 model AWD starts to lock up the diff and is very hard to make it move where i have to over rev engine to get some movement, could anyone help who has had the same problem or has an answer on what i should do?
