Oil is seeping from the front differential on the left side axle shaft and there's a clunking noise when I accelerate from a slow speed. Sounds like a gear is jumping over a broken tooth in the differential. Is it time for a new differential? Or could it be in the transfer case?

If there is an axle seal leaking, it may just be a bad axle bearing. Have you checked them for play?

The clunking sound is the worn chain in the transfer case jumping teeth when I accelerate. I removed the front driveshaft and can drive the vehicle until I can replace or rebuild the transfer case. The oil leak on the front differential is from the vent tube.
