I just bought new Dana ball joints (706944X) for front Dana 30 on a 2001XJ and the lower ball joints seem loose right out the box. What I mean by loose is that I can push the socket pin around fairly easily by hand, with very little pressure. I was expecting them to fell pretty tight being new. The top ball joints are very tight. The balljoints came in a Dana box but they are'nt stamped Dana just some numbers. Not sure whether to return them or not ?
