I notice that Blau is offering a tool that enables one to change the FRONT wheel bearings without removing the strut from the car. Has anyone tried it, and if so, how did it go? Will it work on a quattro's rears as well? I also gather that Snap-on has something similar. Any input would be appreciated. TIA John Corbs Traverse City, MI '83 & '85 Ur-qs (for my sins)
