Hi Guys I have a 2002 Lexus SC430 and I need to replace the following items in my front end: UPPER CONTROL ARMS - BOTH SIDES LOWER BALL JOINTS - BOTH SIDES The parts I got from ROCKAUTO - but does anyone know how many labour hours it takes to replace the above?? Any help would be appreciated - I need to know how many hours it is suggested to replace the above in either MITCHELL or other source or even a LEXUS DEALER. Thanks Erik
