They do vary, I would take your trim tag info from inside the glove box and your VIN from the dash and check with your dealer; that should give you the ratio for your car. Mark any year above I think '79 is stamped right into the axle housing
There are four ways to find a ratio. 1 A dealer can normally tell from the vin number. 2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info. 3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires. 4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

Try changing transmission fluid and filter
I don't see why not! But why would you want to do that?
Take it to a mechanic.

Is a rear end in a 88 4x4 Chevy truck the same as the front in gears of a 93 Chevy 4x4
There are three ways. 1 A dealer can normally tell from the vin number. 2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info. 3 You can count how many times you have to turn the driveshft to get one complete turn of the tires.
Could be any of several. Check the little metal tag bolted to the diff. That truck also likely has a 8.8 rear, not a 9 inch. If the tag says "88" it's an 8.8. The gear ratio will be stamped with no punctuation, i.e. "327" would be a 3.27 gear.
