it only happens once in a while, but I get a hard clunking when my truck shifts. I think maybe it is a u joint? I noticed there is a bit of play in my drive shaft. I am not sure if this is normal..any ideas?

if you can move your driveline up and down while its in gear then ujoints will be the problem. the sooner you replace them the better. dont want to loose a driveline going 60mph it will really tear up under there!
