I have a 2001 Chevy silverado with the 5.3 and im almost positive i have 3.42 gears
Inside the rear axle.Inside the rear axle.
the 3.42:1 ratio was standard for that year if you look in the glovebox there is a white sticker with a list of codes you are looking for in the G section GU6 for 342 or GT4 for 3.73:1.. Also G80 is the code for locking differential.
SAE 75W90 synthetic gear oil
To change the front differential seals on a 1999 Chevy Suburban, first, lift the vehicle and secure it on jack stands. Remove the front differential cover to access the seals, then carefully pry out the old seals using a seal puller or a similar tool. Clean the sealing surfaces thoroughly before installing the new seals, ensuring they are seated properly. Finally, reassemble the differential cover with a new gasket or sealant, refill with differential fluid, and lower the vehicle.
you will need to use 80 90 weight greese in that
Same as the rear.
Yes it is but you will lose by the increase in gas mileage.
No you can not. The front wheel bearings will come apart and fluid will run out of the front differential.
It depends on the gear ratio of the rear ends. You can find this out in the glove compartment of your truck. It should tell you there. Hope this helps you out.
I would visit your local Chevy dealer's parts department. If you give them your VIN number they will be able to tell you the exact rear diff specs for your VIN.
The rear differential plug is located on the inside top part of the differential. Where the drive shaft connects.
You would have to install a gauge on the differential vent, usually located at the top of the differential at the left side
