Subject: Broken CV joint Stud Extraction-Was "Drill-Out"
Content-Type: text/plain; charset=us-ascii
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..

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.
