My lightweight carbon(carrera GT) seat started squeeking last summer. And it gets worse.

I am pretty sure its from the seat base/slider area. This problem started last summer and got worse over time. In the beginning i got rid of the noise sliding the seat from max forward to back a few times. That maybe lubed the slider?

Could it be noise from base/slider out of alignment or the seat adjustment lever rubbing? Or only need for lubrication?

Please check this. Squeeking also when pulling the lever
