While under my truck changing the oil I was checking on stuff. I noticed there is a little play in the front u joint on the rear driveshaft. It's only about 1/16" or so of slop. Not enough to notice any vibration. Need I worry? Should I be in any rush to swap the thing out?

 

yessssss, change it before it goes bad at 55 mph going down the highway like mine decided too. and besides there cheap

 

change it. 20-40 bucks and you dont think about it anymore
