Brake light jiggle

[pdedse]

2017 model I was working on the taillight assembly I noticed that when I tightened the two screws holding the taillight unit into the bracket assembly that even when tight the red plastic assembly is free to wiggle in the bracket

Is this normal? I don’t know why I haven’t noticed it before I’m not missing any pieces as far as I know. I assembled using an exploded diagram to be sure I had all of the correct parts

 
Hello S. Wendelin...

No, it's not normal.  Other forum members and I have had problems with this.  I searched this forum and the other for a fix I came up with involving inserting rubber washers, but the link is dead.

Basically, I think what I found was that the threaded ends of the bolts go in too far, and then they don't grab anything.  By inserting a rubber washer, the bolt's threads grab at the right spot and pull the unit tight, eliminating the rattle/wiggle.

A few photos from the thread that seems to no longer work: 



Or it might have been this washer: 

You might give it a try.  Be gentle with the tightening down. Another member found that his unit where the bolts thread into was cracked if I rembember right.

Edit: since we're not supposed to upload copyright material (the exploded diagram), here's a beautiful artist's rendition of the bolts in question:


Don't laugh.

I believe those threads are too short to tighten down the assembly.  Adding a washer gives the threads more bite in the right spot.  That's my theory anyway.  For me, the bolts with rubber washers pulled the assembly together and no rattle/wobble since (about 6-7 years ago).
