I just replaced mine (Meyle HD) and have the tool available. There are two tool manufactures that exist, the one I bought uses machined cups that take any guesswork out of this - works great. Happy to see these go on to the next user.

See my post elsewhere about who, where, when, why & how of the these bushings (US English) or bushes (UK English). Bottom line: if you have an E53 and they haven't been replaced, it's time to do so ...
