I have put a few posts up about my bad axle u joints that are less then 2 years old and some hollowing I was hearing...Well me and a buddy just got done putting 2 new hd u joints on and all my problems went away. But get this the old u joints that arnt that old I had a shop do cause at that time it was something I couldnt do on my own. well the shop NEVER PUT THE GREASE FITTING ON!! so my u joint had 2 freakin holes in them so of course the joints were destroyed. Think I should do something about this?
