Newbie and proud owner of a '99 RX 300 with almost 210K miles. Have changed out engine, and transmission in the last 20K miles and recently replaced all mounts. There is a distinct popping sound emitting from the left wheel well when listening from the outside and a popping noise under and left of driver side when steering in tight spots like parking spaces or pulling out of my parking ramp and turning to access the street. Recently, because of the grease splatterred under the passsenger side and around the drive axle area, I got an auto repair shop to change out the right drive axle. This did not stop the popping noise. Further, I now have noticed a shimmy on the wheel at speeds above 60mph. Is there any way to confirm that it is indeed the left ball joint and not go throwing good money after bad at parts replacement? Any advise is much appreciated. Thank you all.
