So...looking at those pics has left me a liittle concerned. Is this to be expected of the OEM u-joints...because they're not greaseable? When the joint goes, will the outer shaft likely fail (like this) as well? I was gonna replace the factory u-joints eventually, but this pic makes me wanna replace the axle shafts as well...and SOONER than LATER. If someone could answer these questions, it would be GREATLY appreciated. Also...I'm wonderin how much mileage this jeep had when this happened?
