The idea was to make it easier to remove your fw on the road to replace a broken drive side spoke. The little tool was carry easy. 'Hen's teeth' parts as of today. I also read the bit on smaller drive side bearings/which increased the odds on ds spoke breakage as well as faster wear. Best case scenario is finding one on a garage queen destined for a yard sale. LOL I too am wondering if it will lock up or what-when it goes. Not an appealing thought.
