Hello. I just joined the forum to search for issues within the front drive axle assembly. My initial searches tell me that the front diff is pretty stout...so I shouldn't have broken it.
I accelerated away from a dead stop, went through a wide-open-throttle 1-2shift, and heard a loud pop followed by a grinding sound. The vehicle no longer move under its own power. I took a closer look after flat-bedding the truck home. I have input from my front driveshaft into my front differential, but I have no outputs. I'll be tearing it apart in the near future...so I'll post the carnage pixs when they become available.
Like I said at the top, the front diff doesn't seem to have a reputation for instantaneous failures. My setup is harder on the geartrain that stock...but just through the use of higher shift pressures, quickened shift times, and omission of most of the torqur reduction during shifts. My tires (275/45R20) and a mild exhaust mods are the only mechanical changes to the truck. I've also added a little fuel and timing to my tune, but not much. No power adders...stock shift points.
I'm hoping this is just an odd-ball problem...Anyone else having this kind of problem? If so, is there a stronger (larger) front diff assembly that is a bolt-in option? I'm guessing there isn't because the passenger side intermediate shaft that passes through the oil pan. If there is a bolt-in, I bet would require a new oil pan too. :hopeless
Let me know what you think.
