increases feedback through the chassis but delivers noticeably more precise and consistent handling.\u003c\/p\u003e\n\u003cstrong\u003eWill this bushing kit fix a wandering steering feel on my LS400?\u003c\/strong\u003e\n\u003cp\u003eIf the wander is caused by worn front upper control arm bushings, replacing them with this kit restores the correct geometry and typically resolves the issue.\u003c\/p\u003e\n\u003cstrong\u003eDo I need an alignment after installing this bushing kit?\u003c\/strong\u003e\n\u003cp\u003eYes, an alignment is recommended after any front suspension bushing
