I’ve been trying to chase down a creaking noise from what I think is the front passenger side for about a month now – it happens when I accelerate and the weight of the car (2005 mercury mariner) shifts. It’s mostly a creak but almost a knocking/crunching sound that seems to correspond to when I give it gas.
I recently got my sway bar links and tie rod ends replaced, so I could have sworn it was a bushing on the control arm. Spraying silicone grease doesn’t do anything, and last night I noticed what I think is the same noise happen when I shift from park to drive.
Could this be a worn motor mount? I’d rather replace that on my own than have to bring it in and get a new control arm installed so I can get a realignment.
