How do I determine Ring Gear?

Postby ricka182 [OP] » Oct 03 2011, 11:21pm

I am in the process of preparing to change most of the fluids on my vehicle, including the differentials and transfer case, and tranny. I already know which fluids to use, but I have some concern I'm not sure of the actual capacity to use.

The chart on the AMS site for my truck shows different capacites for different ring gears in the differential and transfer case. They are fairly close, and part of me says to just fill them until the fluid comes out of fill hole..but I don't want to take a chance if someone knows how I can figure it out to be certain..

I have a 2006 Silverado 1500 Z71, 5.3L V8 Flex (Z) engine. Not sure about any other specifics concerning the differentials or transfers case/tranny.

What I'm looking for :

Front and Rear Ring Gear size
What Transfer Case: NVG-xxx-NPx
Which Tranny - 4L60-E or 4L70E
2006 1500 Z71
Onyx Bed Liner
Magnaflow 15, single in/dual out to rear bumper
TC 4" Blocks -- RC 2" Leveling keys

It would probably be good for you to know the sizes, just to know. But your own point is exactly right. Fill the differentials just to the point that some fluid drips out of the filler hole, and you are done.
Buy an extra quart to ensure you have enough, and you'll have no worries.

I hope this helps some.

1500 is usually a 8.6 rear axle with 8.25 front unless you gave the max trailerin option pkg and that includes a 9.5 rear. Typically it takes 5 qts to change out the front and rear axle on all 1500's. The other sizes listed are for 2500 and 3500 series but with trucks anything is possible especially with fleet builds.
The trans capacities are the same no matter what trans you have
The transfer takes a special GM fluid and you can find out which one by comparing option codes to the list below.

Re: How do I determine Ring Gear?

Postby ricka182 [OP] » Oct 05 2011, 2:35pm

Thanks guys! I'm putting the truck up Saturday to replace the torsion bar mounts, so I'll take a look at the gear boxes and see if there any markings on them.

As of, I'm planning to use the Sig Series for engine, the 80w90 syn lube for diffs, the low-viscosity ATF for tranny, and the syn multi vehicle fluid for the trans. I think I got all that right from the AMS site, I don't have the paper printed out in front of me with the specifics.

I also just got my preferred customer package the other day; mulling over to push my friends to buy AMS as well and become a indy dealer..
