Clutch Backlash
I know that backlash is common in 4lo, but ive been having a really lot whenever i shift out of reverse and 1st gear is this normal? Its been getting louder and louder so just wondering if anyone else is having this happen.

Do you mean clutch "judder", where the clutch vibrates and causes the clutch peddle, drivetrain & sometimes the whole vehicle to shake when the clutch reaches friction point? 
It's fairly common on JKs with a few miles on them, particularly when the drivetrain's cold and the air is damp (apparantly it's got to do with the metal particles in the friction material on the clutch-plate oxidising, a bit like when you've just washed a vehicle & sprayed the wheels & brake discs with water you'll notice a fine layer of rust-looking discoloration on them, which disappears when you use the brakes again)

Mine does that also but im talking about when i shift at low speed as soon as the clutch lets go there is a really loud clanking sound, sounds as if the clutch its bouncing around. i know its common in 4lo but i get it in 2hi and it seams like its getting louder and louder.

I used to hear a loud *CLANK* that seemed to be coming from the rear end when I would push IN the clutch pedal at low speeds in first gear. I started giving it more gas and upshifting closer to 15mph rather than 10mph. I don't notice it anymore, it may be because the engine is louder
