Just bought a gently used 2020 Expedition XLT. First time I washed it I noticed that the passenger side rear taillight housing was loose. Took off the trim piece to check the two 10mm nuts and both were tight. Removed the two nuts and housing. Felt no resistance when pulling the housing back towards the rear of the vehicle which makes me think that pins are not locking into the grommets. Anyone else has this issue? What did you do to fix it?
