I have a couple of questions re: the rear diff in my '99 Z28 M6. I pulled the cover off to change out the fluid, and just have a couple of general questions.

The gear on the left ..... I thought that I read somewhere that this set of teeth is part of the traction control system. But my car does not have traction control. At least, there isn't any on/off button in the car. So, not part of traction control?
In the center of the picture, there is a bolt connected horizontally. I pull that bolt out, and remove that clip it is attached to, and I can pull my axles out? On older cars, that bolt would be holding a pinion shaft .... my car has a Torsion unit so there is a clip instead? Are there "c clips" on the axle ends, or do I just pull that clip out and the axles slide out?
Thanks
Bill

FirstYRLS1Z - are "axle saver" bearings the same as offset bearings, where the bearing surface will ride on a new portion of the axle?
How far can I go into the rear diff without having special tools/skills to put it back together? I'm confident that I can replace the axle bearings, but how about the carrier bearings? Is that just an "unbolt/bolt-in" replacement? Can I remove the Torsion unit without effecting the pinion gears, backlash, crush sleeves and all of that stuff? I've replaced motors and transmissions, do all of my brake and suspension work. But I've never gotten into the differential, so I'm curious how simple they really are.

Yes,as long as carrier caps(not interchangeable for position) and shims are put back in their original location.
Carrier bearings require a press for off & on and new carrier bearings COULD affect 'lash'.
