What might be causing sort of a groaning sound from the passenger side of the engine bay when backing up?

PSMM, I bet. Mine used to creak when it was colder. I replaced it with an OEM part from RockAuto for just $30.

I wouldn’t be surprised. It’s squeaky when cold/damp. Near 150k on this and I’m sure it’s original.

Motor mount possibly

Mine is starting to get creaky in the morning as it gets colder too. I’m worried it might be the motor mounts for me.

6

My passenger side motor mount is definitely squeaky when cold/damp. I wouldn’t be surprised if this is also my backing-up noise. I’m just getting used to the noises from this car.

Is it the truck backing up, or is it the stop following movement while in reverse?
