In the book, "How to Keep Your Volkswagen Alive: A Manual of Step-by-Step Procedures for the Complete Idiot", by John Muir, the Bible of the VW-owning set 35-40 years ago, he described a technique for those large nuts, involving a chisel and a hammer, to use if you don't have a big socket. Hold the chisel perpendicular to the nut, near one of the corners. Bang yourself a good notch. Then turn the chisel almost perpendicular, and bang on it again to loosen the nut. Use another corner to tighten it. It tends to knock the corner off, but you still get three overhauls per nut.
I still have my copy of that book, with many of the pages nicely stained with grease.

There is a nut on each wheel and another on the steering wheel. I think that these are 32 mm (I'm not sure because I've never used them). It is interesting to consider Dr Ferdinand Porsche's philosophy from a practical standpoint. To maintain your car your entire toolkit usually consists of two spanners (wrenches) that are exactly the same - 10 mm on one end and 13 mm on the other - one to hold the bolt and another to turn the nut. Your complete everyday toolkit fits into the ruler pocket on the side of your overall. The only time you need the 32 mm tool is if ever you need to remove a wheel - and in my experience that is fairly close to never.

Maybe ant VW Beetle aficionados out there could confirm this. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bill Hooper Sent: 27 June 2009 03:04 To: U.S. Metric Association Subject: [USMA:45273] wrench sizes I was browsing in the auto shop while my car was being serviced the other day and came across something I always "knew" in the abstract but, about which, I did not know the specific details. Maybe you all knew this (or similar examples) but here it is in case you didn't. They were selling two almost identical sets of socket wrenches, one in Ye Olde English units, the other in metric: The sizes of the sockets in the Y.O.E. set were: 5/16, 3/8, 7/16, 1/2, 9/16, 5/8 and 3/4 inches. The sizes of the metric sockets were: 9, 10, 12, 13, 14, 15, and 17 millimetres. The Olde English units were marked on the sockets with quotation marks to indicate inches (e.g. 5/16" for five-sixteenths of an inch) while the metric units were indicated by "MM" for millimetres (e.g. 9 MM for nine millimetres). The examples show so well how metric is simpler to understand and easier to use, that one can almost excuse the use of the wrong symbol for millimetres.
