12K miles
OE drivetrain & suspension
No damage/no bizarre parts/all lug nuts secure (checked)
Exhaust secure (checked) And I've kicked the tips around to see if something contacts - nope.
Spindle nuts secure (checked)
Diff bolts intact (checked)
Sitting still...flat & level pavement...clutch down...select reverse...lift clutch...
CLANK
Sounds like it's coming from beneath the center of the car, but could be further aft.
I can sometimes create the same sound if I select first gear and release the clutch, but it's usually easier to reproduce & more frequent when selecting reverse.
It's just at the first .5 second of engagement before the car begins to move.
If the stick is in reverse, I can make it CLANK - CLANK - CLANK again & again by depressing & releasing the clutch.
It doesn't respond to bumps in the road - only the first few sudden degrees of torsional rotation of the driveshaft when the car is stationary or b-a-r-e-l-y moving.
It sounds exactly like universal joint(s) to me...but with barely 12K miles??
Full disclosure:
The exhaust (new; Magnaflow CBE) and the tranny mount stiffener (new; Whiteline) were both done last Sunday by me. That's how I know they and those other things are secure.
