Pulled my front diff. and sent it to Sandcraft and had it bulletproofed as preventative work. Just took part right side and on 1st ride, the left axle popped out. Thought maybe I did not have it snapped in all the way, so when I pulled it, I replaced it with a new I had as spare. Next ride it popped out again, upon examinatio, I noticed the original was 1” longer. Is the TRE axle Different than the othe XP’s?
