I pulled my axles and differential cover last night.The popping chunky sound was the planetary gears on the differential being shredded,spider gears looked great
but all four planetary gears are junked. This would probably explain the roaring noise,but I don't understand why this happened,the carrier unit was tight and
looked fine when I put it in the transmission. A friend of mine rebuilds transmissions and mentioned that my foot was unmerciful and tortured the differential.
