I paid a bundle in labor to have some coilovers (ST) installed recently. The car has 40k miles, I asked the shop ahead of time if the strut bearings should be replaced at the same time and was told it wasn't necessary. Now, when the car first starts moving in reverse I can hear a low grind/bind sound that seems to go away once driving (unless it's the source of the low/quiet "roar" that I figured was tire noise). It kind of sounds like the front suspension is shifting a little. I think I'm hearing it when slow rolling forward from a stop after sitting for hours also now.
Does this sound like strut bearings or something else binding/shifting? Also, until I can jack the car up again, what would be signs of a bad wheel bearing other than play in the wheel?
