Hey guys, I recently bought a 2008 g37. I started noticing my passenger side start to creak when it moves forward and back/ across the rail. I tried looking for debris underneath and in the rail, but I couldn't find anything. It doesn't sound like it's rubbing across any other part of the car either. I tried putting WD 40 in the rails, but it didn't seem to make it any better. I'm thinking I should remove the seat to check if I can see anything wrong with the motor or the rails. Any advice? Thanks
