Toyota Tacoma TSS Sensor Garnish TRD Pro Grille

I found a new method to secure the garnish cover for the TSS sensor on TRD Pro grilles, instead of fighting those push on lock washers that Toyota uses take a 5/16 course die and cut threads into the two posts that the push on lock washers slide onto. Then use two 5/16 course nuts on the two newly threaded posts.

The push on lock washers are a pain to fully seat them. The nuts will solve this issue and the nuts will not back off of the plastic posts, they are nice and secure. In the video the two nuts were snugged up with a wrench and I was not able to back the nuts off at all by hand and even when the nuts were installed by hand they where nice and snug and would not just back off, you have to twist the nuts to back them off with some pressure so road vibration should be no problem.

If you wanted a extra measure of security you could put a drop of superglue on the plastic stud and the nut after it is installed, do not use loctite as loctite can damage the plastic stud due to chemical reaction of the loctite with the plastic.
