Times can vary from shop to shop!! AT dealer we are SUPPOSED to follow the factory time guide. OF course we have $200,000. + of special tools that MB requires so many times a front end job labor TIME might be less at dealer.
MB allows only 1 hour for both tie-rod assemblies & drag link.
ALSO with factory tools the ball-joints are less than 3.5hrs
However on your car the idler arm bushings are at least 1.5 hrs as the complete exhaust system must come off to remove the bolt thru the idler arm.
