Spider gears are all good everything spins very nice.. Ian stopped in as well and had a look, he as well thought it seemed very smooth.

Transfer case I havent taken off in a bit but last time i did it was smooth, and when i had all four tires up in the air, all for tires spun free with tcase... disconnected my driveshaft and spun my rear diff by itself and it was free spinning.

Front drive axles are new and are good, rears have no play.

I changed the stock line with 8mm hose and check valve from Ziggy. Check valve is in the correct way as well... The stock line was still working fine, but i changed it anyways.
