Hi – this listing is for a Zimber Professional Tools hub installation tool for various BMW models – E36, E46, E60 etc. The front bearing on many models is difficult to re-install correctly as it is easy to misalign and damage them on re-fitting. This tool allows easy, correct installation avoiding these problems. It is a very high quality, heavy solid and smoothly working tool. Also included is a 46mm socket for removal/re-installation of the hub nut. It has been used very lightly and is in good condition and full working order.
