Hello all -

I recently purchased a 2013 that is quite lovely, but has an impressive amount of rattles, creaks, and pops. I've slowly been tracking them down myself, but one of the most jarring is the sound of the body mounts (outboard below the gauge panel) that make a loud crack sound over every bump. I don't believe there is any damage (yet), but it feels like if I continue driving as-is that I risk creating more issues. All of the noises seem to be coming from the forward half.

I've located the body mount bolts located near the driver/passenger knees and at the end of the footwell. All of them feel quite loose. Additionally, there appears to be a stud with two nuts on each side (again, near the knees) which are also loose. I'm hoping that tightening all of these will quiet some of the noise, but I'm unsure of any special procedure or spec for these.

My trouble is that I can't locate any of these in the Parts Book to know whether the hardware is correct, and I haven't seen much discussion on the topic here. I've seen a few posts saying to "tighten" these but I'm not entirely sure how to complete that task. It sounds so simple! Searching here and elsewhere online has been unproductive.

I'm left with a few questions:

1) Is there a particular order that these should be done in?
2) is there a torque spec? The mounting bolts (with the hex head) appear to have a rubber washer, so "tight" is a bit confusing.
3) The outboard studs seem to spin without tightening. Are the double nuts intended to be lock nuts? How exactly do these mount?

Cheers for any assistance you can offer!
