When is 4wd there is a clicking noise when your driving? kinda like a slight clanking? and also when you put it in 4wd ( no matter what position ) it won't go in even if the lever is in it unless you put it in neutral first is this normal?

As I read your discription the second part sounds like it's Standard Operating Procedure for the upgraded "Select track" transfer case that is on at least all North American CRD's.
We have a "Full time" setting where the "Command Track" does not have a FT 4wd setting.
Our shift lever is not directly coupled to the shift fork. Our shift lever pushes on a spring and when all is right with the world and all the stars and planets are aligned the spring pushes the shift fork into position
Even with the exact same tires on all 4 wheels inflated properly some outside procedure is needed.
I have 2 jeeps with this transfer case and what works for me is to pause in part time 4wd when going into or out of full time 4wd. also read the manual on the proper way to do it.
For instance if you are sitting still and have the transfer case in neutral then put the transmission case in any gear when you'll get lots of grinding noise when you try moving the transfer case lever

The clicking sound could be a CV joint, does it make the noise when your turning one way ofr the other?

Mine tends to do this when going long periods without use. When going into AWD usually does fine, sometimes however it gets stuck in 4hi and won't go into AWD unless first shifting tcase into neutral then back into AWD. With regular use, it rarely exhibits this problem.
