Suspension.
#? doesn't have a name in the Nissan parts catalog, but is welded to the front suspension member (engine x-member). I call it a "engine-mount horn".
#15 is bolt that holds the engine crossmember to the chassis (4 bolts needed, two on each side).
#41 is called by Nissan "front stabilizer torsion bar" but is also known as:
- anti-sway bar (or just sway bar)
- anti-roll bar (or just roll bar)
- stabilizer bar
#14 is the "front suspension member", but more commonly called:
- engine crossmember
- engine x-member
#35 is the "front suspension tension rod", aka:
- strut rod
- caster rod (castor rod) [edit: both spellings are acceptable]
- radius rod
#19 is the "tranverse link", aka:
- lower arm (the only arm in a McPherson strut design)
- lower control arm
Note that it is not an A-arm, because it only has a single 'leg' on the inside. A-arms are a-shaped.
