There is a product made called torque stripe.

It is like a wax after it dries and will break or fall off if the nuts move.



this will allow you to tell at a glance if the bolts/nuts back off at all.
we use this in the military.

Comes in different colors too








In the Aviation industry, we call that stuff "bird crap".

I would definitely recommend using either the green (light) or the blue (med) Locktite on all drivetrain parts.  Glad you caught it early.

For the most part green is not what you want. Although the meaning of the colors sometimes varies, "green" usually is a high-strength wicking-type product for press-fit type applications (like to keep a bearing race from sliding around it's housing). It's not really meant for application on threads. Purple, blue, and red are the traditional light, medium, and permanent colors for most thread-locking brands.

Blue is what you should use for almost everything. Red is stronger but in most circumstances unnecessary and a lot more of  a hassle to deal with. Blue has a break-away torque strength of  arround 100-110 foot pounds. Under most circumstances, you only need a break-away torque of arround 30% of the bolt's torque spec, that means that blue should be able to handle bolts up to 350 foot pounds, which should cover pretty much most of the bolts on our trucks, while keeping it easy to remove and re-use. Keep in mind, the point is not to super-glue the bolt, but rather to protect it from small vibrations that can work it loose over time. So just because blue is easy to unscrew, does not mean it doesn't do an excellent job of keeping your bolts locked in at the correct torque spec.

Be aware that not all colored thread-locker products are the same. There are many different variations for different applications. The most important of which is temperature resistance. Normal blue and red loctite are good up to 300-360 farenheit. There are high-temp versions of both blue and red loctite that are resistant to 650 farenheit. So if you are using it somewhere where temperature might be an issue then keep that in mind.
