I got a 2004 Avalanche and I don't think the rear differential has ever been changed. Any recommendations on fluid? Also I'm fixing to change out the hydro booster for my brakes and powersteering. Any advise on that would be greatly appreciated. Thanks
 
Page 6-13 of your 2004 Chevrolet Avalanche owner's manual calls for SAE 75W-90 Synthetic Axle Lubricant for the rear axle.

Any name brand lube should do nicely.

I like to use Mobil 1, when available.
