Anyone else with a tapping/squeaking sound from back passenger doors? i've been noticing the problem last year, but by time service came around it was too late. very noticeable on hot days at slow speeds...the car is consistently 90+ now in tx heat and the noise is also consistent during those times

noticed both back door pieces creak on the bottom if pushed, wonder if they're rubbing against body and causing noise. is there lubricant or something that i could apply to it?
