Cracked sliding mirror doors for bedroom closet

I honestly think that the one side was cracked when our 29RLBS was delivered to us back in 2005. Its been a corner crack that has slowly grown over the past 5 years and will only continue to get worse, I'm sure. I've got a call in to Forest River to find out about replacing one or both sides, but has anyone had a similar experience? We were wondering if those slides popped out and if we could maybe take them somewhere and have the mirror replaced rather than buying one or the whole set all over again.

Kicking ourselves for not addressing the problem earlier.

I have had mine out a couple of times. Lube and adj. Anyway the doors have to be raised up as high as they can go and the bottom will come out. There are adjustment on the inside of the door. I believe top and bottom. Been a while so bear with me. You may have to adjust those if you can not get it out by raising it.
