t-case

I installed a new u-joint in my front drive shaft couple days ago and while down there I noticed that when the t-case is engaged with truck off i can turn the fron shaft about half a turn in either direction before it takes on the gears,is this normal?Could my chain be loose and if so is there any adjustment on it?
93 1500
350 4x4
automatic

Sounds like it could be.How many miles and how hard were those miles?

Lot places it can have slack.
Check fluid level and if not making any noise just keep on driving it.
If it is not broke do not fix it.
If it gets to lose it will let you know.

211000 KMS ,not sure how hard they were as I only had it since 203000KMS.The t-case was low on fluid when I got it cause the rear seal was leaking,I filled it but I havent checked it lately.Everything seems to work fine other than a lil more noise when its engaged but i think its just normal noises.
