Quoted from Pin_Guy:Not normal, but this will be tempered glass so your also not likely to break it. The most likely cause is the glass is getting hung up on the rear trim, you may be able to re position it to correct the problem.
I usually put some simple green in a small cup, soak q-tips in it, then run the q-tips along the inside of the channels. All sorts of gunk tends to accumulate in there over the years and it helps to get it out.
The other reason for hang-ups could be a damaged portion of the channel--maybe a chip or crack.
Otherwise, just make sure the glass is aligned and slide it in gently--it doesn't need to be forced.
Quoted from mystman12:I thought tempered glass was super easy to break from the sides though, or is that just on concrete and stuff? I've read the stories where people end up holding air with a pile of glass below them, so I'm always super nervous when I'm moving the glass!
When setting aside the glass, I usually set the edge down on a folded towel (regular or microfiber) and lean it up against something. I've seen too many after photos shattered/exploded glass after being placed on a hard surface and being moved in some way. Note that this isn't a really that common of an occurrence--I just figure better safe than sorry and it gives me some peace of mind.
