How Do I Know My Truck Has A Locking Diff? - 1999-2006 & 2007-2013 ...

A little more info is needed to answer this question. Where did that info come from? And what is the code on the door tag under rear axle?

1. Support rear of vehicle on jack stands,
2. remove rear wheels and brake drums,
3. put drain pan under rear end,
4. remove rear end cover which will drain the oil,
5. remove the spider gear shaft so that the axles can move inward,
6. Push the axle you want to remove toward center of vehicle
7. Remove C clip from inner end of axle
8. Pull out axle

Somebody has scanned the whole factory manual and it is available at the attached link as a PDF file

most axles you have to take off the differential cover and there will be a large pin that goes through the center of the carrier. this pin usually has a small bolt holding it in place. remove bolt and pin and that should allow you to push axle in enough to remove the c-clip on the end of the axle.then you can pull axle out of housing.

1st jack and use jack stands to safely lift the truck.disconnect brake lines and cables, remove tires,unbolt universal rear end to driveshaft, unbolt center bolts from axle to leaf springs, pull the rear end out from the side-much easier with two people. reverse process to put the new one on. I assume when you say axle you mean entire rear end. If you need to remove one axle side just take off tire and brake then remove rear end punkin cover and pull shear pin to remove your ring gear and planetary gear-pull axle shaft.

In the glove box will be a self affixed tag with many codes upon it. The code starting with the letter G will be the ratio code needed to ID the rear axle

It is possible, you just have to know what gear ratio you have in your Sierra. I had issues with my son's rear differential and did the Salvage Yard and picked one up for $250.00 with less then 45,000 miles. Remember new cars end up at Salvage Yards also.

Here are the Pro code for the rear ends to your Sierra and you can match one up at a Salvage Yard.
GQ1 -- AXLE REAR, STD RATIO
GT4 -- AXLE REAR, 3.73 RATIO
GT5 -- AXLE REAR, 4.10 RATIO
GU4 -- AXLE REAR, 3.08 RATIO
GU5 -- AXLE REAR, 3.23 RATIO
GU6 -- AXLE REAR, 3.42 RATIO
G80 -- AXLE REAR, LIMITED SLIP (POSI TRACTION)

HC4 -- AXLE REAR, 4.56 RATIO

Open Your glove box and look inside it. Should be a list of codes on the bottom.
Example: GU6 G80 According to that, you'll have a 3.42 posi

Good luck and keep me posted and call around Salvage Yards, there prices will differ from one to the next salvage yard and don't ask them for a posi rear end. The cost will you more, just search all the SUV's and look at the pro codes in the glove box. Hunt, most awd system SUV will have the G80 rear end.

Good luck and keep me posted.

You will have to remove the differential cover on the rear end, in the center of the gear cluster you'll have to rotate your axle until it exposes the ends of the axle shafts, push in the axles as far as you can from the brake pad assembly area, then, there this a C clips that slips into a groove on the end of the axle, you'll have to reove the C clip to pull out the axle.

Hi meduck4,heres what you need brother as I cant see your diff, 3 ways to tell what you have:
#1 The first is the driver's door tag; there will be a one-letter or one-numeral axle code listed there. You can then compare it to the chart below: CODE Rear Axle Ratio Conventional Locking 8 M 2.73 Y Z 3.08 F R 3.45 5 E 3.27 6 W 3.73
#2 The second is the axle tag, attached to the lower lefthand bolt on the rear axle itself. The bottom left line will give you the gear ratio, and the type of rear end (S for limited slip non-locking, and L for locking).

#3 The 7.5" rear axle height is shorter than the width and the shape appears "oval".
The 8.8" rear axle dimensions are equal and the shape appears "round".

This will tell you what you have my friend,good luck
