Available from J Bugs for $11.95 https://jbugs.com/product/5748.html (There's also a 46 mm version for "big nut" VW buses).Felix Macaluso wrote:I found an interesting tool at a VW parts shop: it is a casting with a 36mm hole at one end and a 1/2 inch drive hole about 4 inches away. It has a spot to tap with a hammer. Idea is to apply many ft/lbs with a breaker bar and then whach it with a hammer. The impuls, added to the applied tourque, broke the nut loos easily.
It's cheap enough that it's worth a try.

Personally, I remove the nuts with an impact wrench rated for maybe 550 ft-lbs and replace them with an Al Zim "Torque Dude."
You might try renting a big impact wrench--some can do well over 1,000 ft-lbs. The also need big air compressors.

You could also get a "sritking wrench" the professional version of the VW tool.
There are also "tubular wrenches" which are effectively super-duty breaker bars. You get a separate 36 mm box head and a 36 inch handle. I've used these: suddenly a nut that wouldn't budge turned with light pressure on a long lever arm.
