ticking noise, rear end maybe

[Boggin]

so when im driving the b2 i hear a tick tick tick well its more like a TICKthud TICKthud TICKthud and i opened the door doing about 10 and listened and it sounds like its coming from the rear half of the truck and im just wondering what the possibilitys may be. it almost sounds like the prank where you would put a cable tie around the drive shaft.
its like it in 4x4 and 4x2 and as i speed up the tick goes faster and when im in mud i can barely hear it. any ideas?
thanks

Check your driveshaft. If it's a GKN type, that uses two CV joints...and can make some interesting noises when it starts going bad.
