Dear Mika: The AT440 has a dynamic compliance of " 0nly " 10 cu, this means that it is in the low level of medium cartridge compliance. With a right tonearm ( best match with it ) this cartridge can track ok, nothing outstanding, with no problem like the one you report.
If your cartridge is right on specs ( good operational condition specially on its suspension. ) then that Technics tonearm could be the " culprit ": first because is not a good match for that cartridge, second because its bearing and design is not up to the tracking task or third that the tonearm is out of specs.
You can try your cartridge in a different analog rig or in yours with a different tonearm and see what happen. IMHO I think that you don't have to change the cartridge till you have a clear diagnosis of what is happen in your analog rig, of course that you can try a different cartridge.
Regards and enjoy the music.
