Mercedes W126 Ball Joint Tools

The Mercedes Benz W126 is one of the first S-Class vehicles that Mercedes Benz produced. Manufactured between 1979 and 1991, the W126 had the longest production life of any of the S-Class vehicles to date. The ball joint of the W126 requires a specific removal tool that is more common today but was revolutionary during the early model-years of the W126.

Ball Joint Puller

    The ball joint puller is a specialty tool that removes the ball joint from the steering mechanism (control arm) of the Mercedes W126. The C-shaped apparatus has two C-shaped portions, one that connects to the ball joint and one to the control arm. A machined screw with a turning nut attached to it connects the C-shaped pieces. A standard open-faced wrench is used to turn the screw of the ball joint puller, which loosens the ball joint from the steering rods.

Open-faced Wrench

    An open-faced wrench is required to turn the fixed turning nut of the ball joint puller designed specifically for the W126. An alternative to the open-faced wrench is an adjustable wrench.

Impact Wrench

    The impact wrench is a power tool with a torque-driven drill. An impact wrench will remove the wheel quickly from the W126, giving you access to the ball joint. At this point, the ball joint remover tools are used to disconnect the joint.
