Should I be concerned?!

While I was under the truck I noticed that my drive shaft looks like its not in the transmission all the way. I'm pretty sure it's because of my lift. Should I be worried about this? do I need a longer drive shaft?

And I know it looks like its leaking, but it's not. That oil stain is just from where oil spilled out the back of the trans when I pulled it to replace my clutch.

 

A lot of drive shafts have an amount that they can move in and out of the transmission as the suspension moves up and down. I wouldn't be concerned unless it is coming out a lot, like an inch or more. The coupler should go in on the shaft a good 5-6 inches, half an inch wont hurt.

 

Alright cool, thanks guys!
