I was drivin my truck yester day and it strted revin fast and not pullin that much so I shut er down and checked to see if I had stiped any gears or if something was loose so I couldn't find anything wrong so I fired her up and it did the same thing so I thought diffs sre gone so I tore it down and found a toothless front bevel gear which didnt suprise me but when I opened up the pumpkin on the rear end it looked like thespider gears had been welded to the endside of the pumkin. I have had blown diffs befor but have never seen anything like this befor and I was woondern if you all might know what might have caused this.
Thanks
