My Gu patrol front differential is engaging while driving and making A clunking sound every now and then could it be in the transfer case ? ?

Thanks it’s not the hubs I’ve taken them off and gone for a short drive but still clunking and I can see the front tail shaft is turning ?
Have you got the right fluid in the transfer case?

Where is it clunking from? Inside diff or ends of the axle? Or perhaps the transfer case ?
It very well could be the transfer. As @mudnut said, transfer fluid ??

If gear oil of too heavy a grade is used, the spinning action of the drive shaft running through the TF can act as an unwanted hydraulic drive, especially if it is cold.
If you have auto hubs you must use auto trans fluid in the transfer case otherwise the front diff will try to engage.

When I did my oils I wondered why the transfer case was transmission oil and not gearbox oil. Put tranny in it as directed but wasn't convinced but never had any problems. This makes sense now.
replying to @mudnut post also.
What is the charge? Eating a meal? A succulent Chinese meal??

I've wondered about that too, have even seen posts here about the manual's different recommendations, with some folk using transmission fluid & others (like me) using a heavier gear oil. Have never seen any mention relating to manual or auto hubs before. Now it makes sense! Thanks Mudnut.

Even in the GQ they changed the fluid.
