need the code off rear or find RPO code inside glove compartment
it will be the same as the rear diff
The HOUSINGS are the same, But the gear ratio is probley different.
Same as the rear.
BEST SUGGESTION IS TO USE RTV SILICONE WITH A SEAL A SNUG THEM REAL GOOD
It will be the same as the rear. Write the VIN# down and call a Chevy dealer and ask for parts. Then tell the parts man that you have the VIN# and you would like to know the GEAR RATIO of your truck.
i think its above the diff
Simply by jacking both rear wheels off the ground,put it in neutral,handbrake off, and chock the front wheels, and then turn the rear wheel 10 revolutions, and count the number of revolutions the tailshaft makes. For example, if it makes almost 38 revolutions, the diff ratio is 3.78:1. Alternatively, If the diff is out and you can't find a ratio stamped on it,count the teeth on the crownwheel and pinion gears, and calculate the ratio from this.
my book says 80w90 gear oil. if it a limtied slip you gl5 with 80w90 wt
Texas edition adds a 5.3L, G80 locking rear diff, 20inch rims, towing package, and the Texas badges in and out.
depends on the gear ratio to begin with. keep in mind Z-71's are four wheel drive. If you change the rear diff ratio you also have to change the front diff as well.
There should be a small metal tag on the rear diff attached by one of the bolts. if that one is missing then check on the front diff. They have to be the same or you will do massive damage to your truck in 4X4. If they are both missing you're going to have to open the rear end and figure out what you have. You may have heard terms like rear axle ratio or final drive ratio. These refer to the gear ratio in the differential. If the final drive ratio is 4.10, then the ring gear has 4.10 times as many teeth as the input pinion gear. You could count teeth and figure the ratio out. You may be able to get more information at the site linked in the Related Links.
There will be a small metal tag on the rear diff. It will tell you your gear ratio, and will have an "LS" after that number if you have a limited slip.
