Rebuilding suspensions is straightforward but it is one of those projects that seldom goes smoothly. The key is to invest in the proper tools. Chain auto parts stores will 'rent' tools but I haven't found any that are designed to work on a BMW. Usually at least one part that has to be pressed will be big trouble and the shortcoming of the generic tool will rear its ugly head and hold you up until you buy what you need. I suggest investing some of the $$$ saved on labor to purchase correct tools. You can never have too many tools.
