The odometer just clicked on 200,000 so along with putting in a new fuel pump, fuel filter, air filter & spark plugs I plan on changing the oil in the front differential, transfer case & rear differential (did the motor and trans a 1,000 miles ago) but my repair manual only lists the what weight lubricant to use and not how much they hold. I'd kinda like to buy all the fluides before hand instead of having to chase back to town for another quart or two, any help??? Also, I plan on using royal purple oil, has anybody ever used this stuff or is it a waste of money??

 

what vehicle

 

2003 silverado extended cab short box, 4 wheel drive, 5.3 automatic, manual transfer case.

 

I believe it's 2 quarts for the front and 2 for the rear(with limited slip additive in the rear). Check the fluid with a allen key and it should be 15mm-40mm below the fill hole if you use synthetic
