sory but i dont think tht anyone sells that tool other than mb.and second of all if u have never replaced a rear wheel bearing on that kind of car before than i would say just one thing .....dont do it yourself.it is not the easyiest to do.the tool can be bought from mb ,but i would not start it cause someone else might be finishing it.And i am not saying that u are incapable ,but it is a bit complicated and having too punch out old races and installing new once. Ive done over 50 rear wheel bearings and i would not attemp it on the floor and without the tool and a loooog prybar
