Yeah they look ok, at least the ones I can see.
What's peculiar is it's only one time.. after whatever is moving settles into its spot for either forward or back, you can drive 100 miles and never hear it again. Heck I drove 150 miles on Wednesday and only heard it once, when I was leaving the house for the first time, then once more when I backed out of my spot in Ft. Collins. It's only when you switch directions that you get it one more time. So if it were a bad motor mount, tranny mount, or even a loose u-joint or driveshaft or broken CV, I'd hear it a lot more than just once, right?
