Well Arch lets kill the myth dead!

I mentioned loctite green because Mondello recommends it for putting on
loose harmonic balancers. My mistake, made without checking.

Loc-tite green is not for taking up space either, although it will as part
of the application. It is a bonding agent. I would not recommend it for
installing new ball joints, unless you never want to replace them again.
General rule is that threadlockers are red bottle, and bonding agents are
green.

I have however sent an e-mail to loctite and asked them the following:
1. If it can be reversed and easily removed if the need arises.
2. If it can be used under the mounting face of the ball joint, securing it
to the a-frame, and in conjunction with loctite 271 on the bolts.

You will have permanently bonded the metals together and very difficult to
remove. Please see:

Bonding
Bonding is now a full partner with bolting, riveting and welding as an
assembly method. Joining materials with adhesives offers significant
benefits over mechanical methods of uniting two materials. An adhesive
distributes a load over an area rather than concentrating it at a point,
resulting in a more even distribution of stresses. The adhesive bonded joint
is therefore more resistant to flex and vibration stresses than, for
example, a riveted joint. An adhesive forms a seal as well as a bond. This
eliminates corrosion which often occurs in a mechanical fastened joint. An
adhesive joins irregularly shaped surfaces more easily than does a
mechanical fastener. Other benefits include negligible weight addition and
virtually no change to the time in which strength must be achieved, the need
for surface preparation, and the need for eventual disassembly. The growing
variety of adhesives available in the marketplace makes selection of the
proper adhesive a challenging experience.

Proper choice of an adhesive is based on knowledge of suitability of the
adhesive for the particular substrates to be bonded, appropriate surface
preparation, curing the adhesive correctly, and matching the strength and
durability characteristics of the adhesive to its intended use.

Please select on of the adhesive types below to learn more about the many
bonding options available from Loctite.

What you want for front suspension parts including ball joints is loctite
271. It is specifically made for front suspension parts. see the following:

Threadlockers
Prevent loosening with anaerobic liquid threadlockers.

Invented by Loctite Corporation as a revolutionary method to positively lock
and seal threaded fasteners, anaerobic liquid threadlockers cure (harden) in
contact with metal if there is an absence of air. That's why threadlockers
are perfect for threaded assemblies. The threadlocker adhesive fills the
entire air space between the threads, forcing out the air. So the
threadlocker can bond to the metal and cure, creating a secure, unitized
assembly that will not loosen. Also, the gap between the threads has been
completely filled, thus sealing the assembly from moisture, and preventing
rust and corrosion.

Threadlockers are available in a variety of strengths to fit all of your
applications. Most threadlocking assemblies can be easily removed with
standard hand tools, or by the application of heat.

Cost savings are a major advantage of liquid threadlockers. Mechanical
threadlocking devices can cost three to four times more than liquid
alternatives.
