The suspension lift won't cause that issue but a transfer case drop sure can. Or perhaps the transfer-case linkage simply slipped a tad out of adjustment which they do.
When it slips, the t-case lever can't pull the t-case completely into 4Lo so you need to adjust the linkage which is a one-banana job that only requires a 1/2" wrench.
With a helper shifting from above, crawl underneath your Jeep so you can see your transfer case linkage. Have your helper pull the lever into 4Lo so you can see how it works. Then loosen the bolt circled in the below photo so you can position the shift linkage rod a little further into its holder on the linkage so it can pull that shift rod far enough.
It's easy once you've done it and not too hard if you haven't.
