Ron and Listees, Using the Ron Bloomquist technique, with some modifications, including the information in the attached site, I removed the below-the-surface stud/broken outer CV joint bolt from the hub of my Westy in about a half hour this morning. The hub remained on the vehicle, and I approached it from the bottom, after having jack-standed the Westy to a height convenient for me to install the half shaft on which I installed CV joints obtained from busdepot..com. I found that working on the stud while it was at about a 9 o'clock position was the most convenient access for the tools and for my viewing.. Bookmark the site:.http://www.team.net/sol/tech/BrokenBolt.html I wrapped my Dremel and electric drill in transparent plasitc bags to avoid fouling them. Using a "long," sharp punch (an important item to making sure the starter hole is centered), and a tungsten carbide cutter (Dremel 9910), I very carefully indented the center of the stud with the punch, and, with a delicate pressure on the stud with the cutter, I cut a shallow "starter" hole with the Dremel. With an electric, reversible drill, I progressed from small bit sizes to larger sizes, cleaning the debris throughout the process, until I was comfortable with the mating of the largest E-Z Out compatible with the hole in the stud. A slight turn of the E-Z Out with the appropriate 8-sided, extended socket and the stud fragment emerged easily from the lubricated hole The key, to me, is the "patience" referenced in the team.net site. AND it was another balmy day here, too. Tom Hanlon Palm Springs, CA 84 Westfalia Ron Bloomquist wrote: > Has anyone used this product (Tom)? I've twisted off more easy-outs than I > care to admit.
