Thanks guys! I know I can jack up the rear end to find my gearing, but anyone know what the stock gearing would be?

Would it be listed in the RPO codes, the sticker in the glove compartment? Mine is listed there.

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 (POSITRACTION)

HC4 -- AXLE REAR, 4.56 RATIO

EDIT: New member, and I didn't see the multiple pages to the thread, so this question has already been answered regarding using RPO codes. Sorry about that!

Installed new rear brakes pads and 1-1/2 inch rear spacers. Now the offset looks much better as the fronts stick a little bit outside the fenders.

Maiden voyage drive to the Desert this past weekend towing my 18' Toy Hauler with no toys in it. I would weigh it to be around 6500K.

Some grades got trans temp to around a 240 degree level, average towing on flat was around 210. Engine temp stayed around 190. Does this sound about right?

Going to change the trans filter/fluid/gasket and engine oil/filter before the next trip next month. Going to be adding about 1500 pounds to it with Desert Toys in tow.

That would be one hell of a hunting vehicle. Put a Big Game Boy on the hitch to haul around your game. They make them big enough to carry a moose and with that 8.1 L and if you jack it up and put some big tires, you could drive up to the moose. Field Dress it put it on the game boy and your on your way with not much work at all besides dragging it onto the the tail hitch game carrier. Roll it onto a tarp and drag it onto the carrier

That would be cool, but not much moose hunting in San Diego :superhack:

I wanted to tell you they have new leather seats that match yours because they match mine and they are easy to wrap the leather after you remove the old cracked seats plus you could add more foam so they are like new. If your interested let me know Ill give you the Ebay # for the front driver and passenger new leather seat covers. Plus Ill look for the back seat for you to. Plus you could get All Black Leather with Red GMC on the head rest for Front, rear, and third seat which would look killer. For the original bottom seats in the front is Ebay # 252581992716 Driver Bottom and Passenger Bottom Ebay # 252581992280. I can find everything you need under $1000 for everything if you want me too. I love the truck and I would love to see it resurrected. Take Care. Jonathan

Yeah, when I get the spare cash, I will do the drivers seat back and bottom/seat back on the passengers side. I got the drivers seat bottom replaced from a matching color leather cover off ebay months ago. It was in terrible shape when I bought the truck. I'll use the same seller.

To do the front and back seats in the front would cost $450 dollars if you work with them. The same in the Bucket seats in the back. The Third seat was a little more than I though it was $550. But If I were you I would pull all the seats re carpet the floor front to back and then install the seats reupholstered and if the roof line is good your good to go. Im sorry if Im a nuisance but I like helping when I can.

Installed a brand new radiator. Put a lower temp thermostat (180) and new belts. Not a leak in sight. Temps on tranny and coolant are nice now. Flushed and filled with Dex-Cool as the PO had the green stuff in it.

Ughhhhhh. ATF in my coolant reservoir and it started to overflow. Trans cooler inside the radiator must have cracked. She never got hot. Not happy at all.

Oh man. Time to flush everything really well. I'd get a trans cool 40k and just bypass the rad.

What a bummer! You replaced the rad and trans fluid/filters just last year. What rad did you get? I'll be staying away from that brand.

Definitely not good, hopefully a speedy recovery and doesn't hurt the pockets too much.

Agree. Spent half the day removing the radiator. Dropped it off at the autozone, which needs to be ordered. Will reinstall and have it towed to the shop to get the trans and cooling system flushed and re-filled. Already started a claim with autozone on this. My Yukon was doing so beautifully until this. Never overheated, both engine and trans even on trailer hauling.

The only good thing about this, is that I now have the time to install the Derale trans cooler that I bought 2 months ago and hook it up to my existing factory cooler.
