Tonearm causing static noises?

Tonearm causing static noises?

Im receiving distorted-like static noise whenever i touch or move the tonearm of my LEFT turntable. Never had this problem before, it seems like a grounding problem. Both of my TT grounded to Rane SL-3 Box, everything seems to be in their place. Not sure where this problem is comming from, im sure it has to do with the tonearm. I tested by vibrating the turntable, tapping the vinyl, pushing and hitting this and that, etc

Just want to know if this is a common problem? where should i start fixing?
should i replace the tonearm?

I tried replacing/removing the cartridge, doesnt work either…
im lost

Update:
Im getting noise just by placing the stylus on the vinyl while is stopped..

this reminds me of when i first got my TT and I forgot to ground it.. this is really bothering me..
please someone spare help

check the wiring of the tonearm, and the wiring of the cartridge.

are you lickin ur needles b4 u screw them in? those 4 posts on the end of the tonearm can get rusty n cause noise!
