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.
Your best bet is to just visit your family doctor. It is not advised to look on websites towards the help of strangers for something as serious as prostate cancer. Let a doctor do it.
3.08
Same as the rear.
It might. Depending on width and bolt patterns. But the gear ratio maybe wrong. Consult a locak mechanic about checking into your gear ratios
80W-90 gear oil
no they will not fit the gear ratio is different and the 4x4 axles are longer you will chew out the transfer case as soon as you put it into 4x4 on something packed
Check in your glove box for the code... 2.73=gu2 3.08=gu4 3.42=gu6 3.73=gt4,gq1 4.10=gt4 G80=posi trac
yes there the same
You have to know three things, the transmission type, the transfer case type, The rear axle gear ratio. Also in some cases, the underdrive. Enter the information in the site linked below and you will get your answers.
The rear axle ratio is 3.73 for a single cab short box and 4.11 ( Or 4.10 I've seen both quoted) for long boxes and extended cabs.
depends upon the truck, diffrent ratio's were used
Remove the end cover on the differential and measure the ring gear (the larger one) I believe they are about 7.5" and you should have a new gasket or gasket maker on hand also 80 -90 sae weight gear oil and if the rear end is limited slip you must add a small container of GM additive to the rear end as well.
it should bolt right up
