anyone here that is running an XJ shaft have that problem? Well, when were fixing my steering last week, my buddys dad noticed that one of the caps on one of the ujoint was busted, allowing it to make a clunk noise, and cause play... are these replacable? I thought I remembered seeing a "key way" of some sort on them.... So, should I: buy a new XJ shaft, or just buy a Borgeson shaft? Or, could I use something like this, from Borgeson ????
