The last thing to consider is that GM used a standard cut gear in the front which is well known to be weaker when used in a front axle application (vs a revese cut gear, think Hi-Pinion diff in the front). This is because the gears are running on the "coast" side of the ring gear teeth.

No, the front axles use a unique ring and pinion, they are not the same as any rear axle gear set. They do not use the coast side as the drive side. You may be thinking of Dana 44 gears from the 70's. </div></BLOCKQUOTE>

What's unique about it? All I've read so far is in the material density nothing about how the gears are cut.

Standard cut, vs reverse cut gears are still very current. Its a low pinion design, its running on the coast of side of the ring gear teeth when used in a front axle application.

The backlash measurement is interesting...that would allow of a whole lot of slop between the ring and pinion. </div></BLOCKQUOTE>These Ring/pinions are not interchangable front to back. These are designed for front wheel drive, so, obviously it's not on the "coast" side.

They've been dedicated ring/pinion sets for the front for quite some time.
