Does anybody have the Lexus PN for the driver and passenger ball joint assemblies? The time has come for me to do mine after ~222,500 miles.

It would be for a 2008 IS350

I understand this to be an older discussion however, in process of having the left / right ball joint assemblies replaced;;

- OEM part 4334039505 – Left Front lower ball joint / RWD
- OEM part 4333039625 – Right Front lower ball joint / RWD
- OEM part 43330-39635 - Right or Left lower ball joint / AWD
