finally changed the u-joints. i need to remember to load the pictures so you guys can see how terrible the one was. i cannot believe it didn't until recently, the internal bearing races that are part of the center of the u-joint assembly were almost half way gone on one side and visibly worn away on the other side.
the old ones were moog and had no place to grease so that is what happened to them. the new ones are spicer and have zerk fittings and to grease like normal.
vibration is all but gone on the ol tj. i believe what is left is from the tires and i believe that are some broken transmission mounts under there. its a slight tiny vibration at take off now, once you are over 10mph, its gone.
i hadn't done u-joints in many many years. what a pain these were to remind me what needs to be done. took a decent sledge to whack them out.
