The Mueller-Kueps Ball Joint Separator System, No. 609 033, offers three interchangeable fork sizes (24mm, 27mm and 31mm), which are attached to the center screw to allow continuous adjustment within the jaw capacity range (30mm to 65mm). Designed for use with an impact, the separator is drop forged and comes with a “Vibro-Impact” reaction screw. This separator system will save time on ball joint work and helps users avoid damaging ALU parts and rubber hoses. This system can be used on certain Audi, Volkswagen, BMW and Mercedes-Benz makes.
