axle fluid capacity

[niceguypmp3]

on an '03 trailblazer with the G80 locker in the rear, what is the fluid capacity for the front axle and the rear axle? I know i'll have to put in the limited slip additive but if i buy a gallon of mobil 1 synthetic 75w90, would that be enough to do both axles?

The Information can be found in this Maintenance and Lubrication PDF as Part of the Service Manual for the 2002-2005 Traiblazers, Envoys and Rainiers that can be Downloaded from the Links provided by @Mooseman's Signature Line:

I am pretty certain that according to owners manuals etc you DO NOT need to add any additive.

That is correct. G80 does not need an additive. Just 75w90 synth gear lube front and rear.

One gallon should be plenty to do both. Like TJ and Moose said, don't put LSD addative in, you'll actually do more harm than good to the G80 because it's NOT an LSD.
