It is not uncommon for a freshly CLA'd Nikkor to be a bit stiff. I had that happen with a few SLR Nikkor's when CLA'd by Mora Camera Service years ago. They loosened up with use.
How bad is it? Does it start to dismount the lens?

not that bad but not fast action is impossible

the grease on the focussing helix is too stiff.

would the repairers do it again with thinner grease ?

heat the lens with a hair dryer and then work it back & forth.
