Does anyone know what the diff cover bolt torque spec is? Is it 25 lb-ft?

I am not even up to 20 lb-ft and those things feel like they are going to snap any second.

tight with a 3/8" ratchet...

20 Ft Lbs.

I use a 3/8" rachet and hold the handle close to the head so as not to over torque it. You don't need alot.
