......actually includes all rear wheel drive GM vehicles with solid rear ends which were built within the previous 40 or 50 years

There's gonna be a tiny bit of in/out because the end of the axle against the pin. Usually there's a tiny bit of up down movement even with new bearings. TINY not sloppy.

Through the big hole. Put the axle gears on , then roll one spider in at a time and insert the shaft. You'll have to try several times to get the two shaft gears timed with the axle gears. Keep trying. Be patient.

Mine is the same as this and is GU6, I think it is considered 8.6

I assume you removed the pin inside the diff that keeps it from moving?

I had that on one side also. I had somebody bump the axle hub as I worked the c clip. It was pretty snug going in too.

If you need JUST the axle shaft, you can use any SIX LUG axle shaft from 1999-2006 Suburban, Tahoe, Avalanche, Silverado, Sierra, Escalade, etc. Drivers or passenger side axle shafts are the same......however, if you need a complete axle assembly, you will need to use 2004-2006 axle assembly from a truck with 3.23 gears (which is RPO Code GU5 as labeled on the sticker in the glove box. As importantly as the gear ratio is, you also need to make sure the axle assembly has the same brakes on it. There are four different types of brake options on these axle assemblies. The brake options are: Dual piston disk Single piston disk. 17 inch drum and another size (inch) drum. Though I don't recall what that other drum size is at the moment. All that being said, your truck being the GMC Sierra 1500 model, it more than likely has the 17 in drums on it. You can determine if this is true for your truck if you see RPO Code JF3 on the glove box sticker label. JF3 denotes 17 inch drum brake option. GU5 denotes 3.23 gear ratio option.....and more info, RPO Code G80 denotes Limited Slip differential. Additionally, if you need a compete axle assembly and can not find one for your 2005 truck within the years 2004-2006, you can use a 1999-2003 axle assembly BUT you will have to install your rear brake components onto the 1999-2003 axle assembly as the 1999-2003 axle assemblies come with disk brakes only. Obviously, you'll want to make sure any of these earlier axle assemblies have 3.23 gears in them (RPO Code GU5).

......one other thing, that retainer bolt which holds the center pin in place is originally installed with a thread locking compound. It's not necessarily tight, but it is locked in place. It takes great force to break it loose. This being the case DO NOT try to remove that bolt with a 12 point socket or 12 point wrench. If you do, the bolt head might strip and if it strips you'll never get it out of there. It is better to use a 6-point socket or a 6-point wrench. Whichever tool you choose to use the size will need to be 8mm..... And if you choose to use a socket, you will need to use 1/4 inch drive ratchet/socket as there is very little room to access that bolt using physically larger 3/8 inch drive tools. And once you get that center pin out DO NOT rotate either of the axles nor the drive shaft. If you do, the two smaller "spider gears" and their shims will fall out. You'll have a hell of a time reinstalling those pieces getting everything lined up again.

@@megatonesilva6546 Thanks man! You should seriously make a video showing and talking about that, as I feel it would help a lot of people.

Is there a measurement I need to know when installing a new c clip and axle? I was told by someone that there is a measurement between the end of the axle to the pinion shaft.

​@@megatonesilva6546 17" ?????

Basically the same

Perfectly normal assuming you have the center pin in.

No different mounts for axle since tahoe has 4 link

@@Golden_6.7 how about a 2004 Tahoe rear end gears and pinion will that work in a 02 Chevy 1500

Just because someone activated the brake line delete option doesn't me you should be a dick about it he did everything great and spoke well to help someone ya dick

Sorry but no. Good luck though!
