Séparateur de rotule
Please be aware:
A ball joint splitter is used to generate tension between the ball joint (track rod end) and the surface it’s mounted on (steering arm).
The idea is to create tension, then use a hammer on one side of the surface and a hammer on the other side to ‘shock’ the connection and let the tapered part release.
Just increasing tension until something breaks or pops off is not the intended use of these sort of splitters. No warranty is provided if you increase the tension thus far that the splitter literally breaks.
