I’m gonna try this. I almost took the covers off like you mentioned.. my issue is that I had my seats in the down position for very long and now when I try to set them upright, they won’t lock in. So if I brake semi hard they come slamming back down. Thanks for the tip and hopefully I don’t have to take the covers off resolve this.
I'm a fan of fluid film type sprays. Learned about them in the marine industry I work in. Anything that seizes up or squeaks on my Jeep gets hosed with it.
