I have a 86 Silverado with corporate open carrier 10 bolt axles. Today i backed outta my driveway and went to pull away (i reved it up a bit and lauched the clutch) and a horrible metal cluntching like gears not meshing together right, sound emitted. I thought it was the transmission at first, but just now i went out there to move it and left the door open and it sounds like it from the rear. Plus when i went to move it forward (its parked on a slight hill in the rain) the right tire was spinning a little and i wasn't moving, but it was jerking and making all the clunking sound. Then it clunked hard and then shut up and suddenly all the power seemed to go to the left tire and it rolled right up the driveway.. So i have a feeling now that i broke a tooth off the gear inside the pumpkin. Does this sound right? Please give me any opinions and help. I gotta fix my trusty brute. Plus my Formula isn't insured to drive yet ;( I hope its the rear-end, perfect excuse to finally get that locker, unless the axle splines are whats broke.
