Clunk from rear end

[lanej2]

Anyone have a problem with a clunking noise when taking off from gears one through three? I notice it most going up hills. Mechanic says it isn't transmission. I'm confused of what it could be.

It could be a number of things, one would be worn out pinion bearings, chipped and damaged ring gears, broken spider gears, or worn posi-traction or limited-slip clutches.

Wow. That's a lot of options. Any way to test some of these options to eliminate them?
