For those that have trucks that are eating joints, you probably need to take your shafts over to a reputable shop that specializes in driveline fabrication and repair.

You'd be scared to death if you know the amount of run out that some of the driveshafts on our trucks have.

My front rear section had to be remade as the driveline shop could not tweak it back into zero, it was that poorly made.

 

i replaced mine at about 120000 and they still had some life left. My truck is a 2wheeler though.
