Transfer case problems

I have an 02 and today while looking under the truck I noticed two problems with the transfer case. Where the transfer case rests on the support between the two frame rails. On one side where it bolts on the tranfer case is cracked and some peices are missing. On the other side the bolt was all the way hanging down ready to fall out. I tightd up the bolt again , but im hoping the crack dosent give me any problems. Anyone else have this??
