Tech Note 1: Threadlocker and Anti-Seize, When to Use
Shop manuals may or may not specify the use of a Threadlocking compound. Most older manuals do not make any reference to any thread treatment, but most recent ones do. With the exception of wheel lug nuts, most threaded fasteners used in automotive drivetrains could be candidates for either a Threadlocker or anti-seize compound. If your service manual gives no guidance, you need to base your decision on both environmental conditions (corrosive and/or wet) and the consequences that may occur if a fastener backs off. As a basic rule, I apply Threadlocker to most fasteners such as spindle bolts that could cause severe consequences if they loosened up. For things like crossmember bolts that usually do not come loose, but are subject to corrosion, I use anti-seize.

Tech Note 2:Directions
1. Clean and dry parts using Permatex Surface Prep activator, 24163
2. Shake packet of High Strength Threadlocker well before each use.
3. Cut or tear off corner of packet.
4. Apply to threaded areas and assemble parts.

Tech Note 3:Parts Not Clean?
Sometimes, threads can’t be cleaned of oil residue or other contaminants. For these applications, consider a Surface Insensitive Threadlocker.
