4100 miles and front end pop
 

the car is bone stock other than a set of 17x9 +42 wheels with 245/40R17 super sports and in the morning when pulling out of the driveway i hear a pop from the front right. this morning on flat ground with the wheel turned it did it... i originally just assumed it was a swaybar end link but i doubt there was enough change in side to side attitude on flat ground to upset the swaybar. what is known to rattle loose on the front suspension of these cars?

I have hotchkis springs sitting waiting to be installed but i want to make sure everything is okay before i go changing parts and have toyota/scion tell me my springs effed up whatever was already torn up...

I get a single pop sometimes when turning sharply at low speeds like backing into a parking spot.

Totally stock suspension, not sure what it is.

Long shot but I dealt with a similar issue for a year to find out it was the firewall/strut braces being slightly loose. Re-torque.

Sounds like a bad strut bearing.

Whiteline had a shit ton if issues with this, despite using the same bearing as the stock mounts. I'm pretty sure it was due to the bearing not being installed at the correct angle. They tried to make the mount work in three different positions, to appeal to as many people as possible. But the point loading caused by the angle of bearing and durameter of the rubber caused them to fail. Long story short, these cars seem to be very sensitive to minor issues with strut bearings.
