Update:

After further inspecting the lens, I also noticed a mark/defect on the front element, so...

Went to B&H this morning for an exchange, no hassle!

New lens seems to be a bit quieter on Aperture change. Grinding noise on focus seems the same, maybe a tad softer. I'll test sharpness tonight and if it's good, I will keep it for the price.
