Yes there is an upper strut bearing that affects steering. I had the same problem for 2 years, could never figure out alignment, alignment would go out of whack with every test drive.
Also turned out there was a Nissan TSB on upper strut bearing, I have yet to go in dealer to see what BS they come up with. I have the letter in front of me but it has no TSB#, looks like it goes off VIN#.
Not guaranteeing this will be your problem but it's something to check. Mine caused alignment & steering problems for a long time and even failed once in Mexico leaving me to fend for myself for 600 miles of desert with a crooked wheel and strut stabbing the battery.
