Trailer brake controller? Never seen it in the 800s, first offered in 1/2-ton 900s in 2009.

There will be fellas along in the morning who know what's wrong. I've read the posts many times before but my memory fails me. If you don't see any activity by 0900, give it a bump.

Those marks are from the machining process, everything looks original to me. If your driveshaft is shaking, it will soon cause a leak at either end, the pinion seal or tailshaft seal and soon after would destroy them both. How many miles and what year is this vehicle? Do you feel the vibration in the seat or steering wheel strongest? When did this start? Have you: Measured the play in the upper and lower ball joints? Measured the play in the inner and outer tie rods? Checked the condition of the front and rear sway bar bushings and end links? What brand tires are you using and how many miles are on them?

In my youth, riding a motorcycle would have been a death sentence. My muscle cars were faster than motorcycles and those got me into enough trouble! Nowadays, no motorcycles for me still, too infirm to ride them.

I'll never trade safety for gas mileage, consider the costs friend.

Research done long ago showed me that the panels themselves were done for after about 8-10 years. This was ten or fifteen years ago.

In many instances that I saw, they are! Bad again! Oil is the life blood of prosperity and freedom. Without oil, a society is not prosperous and cannot defend itself. Global Cooling, Global Warming and now Climate Change is the same Communist plan to destroy America while laundering money to corrupt politicians. American Communists, like all of them, create nothing and destroy everything. Remember when paper bags were destroying the earth? Now their plastic bags are destroying the earth. They are the ones working tirelessly to destroy the oil and gas industry and cease our use of the natural resources God has given us. Oil does not come from dead dinosaurs or the vegetation from the flood. That's another set of lies. It's made deep down in the earth. Ironically, the Soviets discovered this during the Cold War, they were forced to drill down two and three times deeper than the west and made the discovery. Sam's Club - $4.729 for 93 octane.

I don't know that Florida's governor has the power to tell FPL how to generate electricity. No, they are doing away with boilers and steam turbine generators for smaller gas turbine generators. So they need 7 GTGs to do the work of 3 STGs including down time for maintenance. From my unlearned observations, the GTGs also require even more cooling water than the old set up. They also claim to be more fuel efficient but in my experience that has never been so. The units are much smaller, requiring more of them to do the same work as the old turbines and while the old plants were designed to run two up and one down for maintenance, I reckon they are going to have 2 or more of the new units down for replacement or maintenance. On paper, the new plants generate more power, along with the 400-600 acre 75 MW solar farms. Another boondoggle. As for DeSantis, you sound like his opposition and are projecting. That article jives with my observations.

only because Texas was dumb enough to reduce their electrical generation capacity. I'm watching this happen in Florida too. FPL is replacing old steam plants with smaller gas turbine generators, 7 replacing 3 in many cases. On top of that, they are putting in 75 megawatt solar farms of 400-600 acres as well. Stupid doesn't even begin to describe this. Treachery does.

I updated and replaced the file above. Makes it a little more user friendly and informative and deletes some useless and incomplete information. Update, tweaked it again just now. It's never been peer reviewed and it wasn't built by a committee or team of engineers, just me. I fix it and modify it along the way.

6YH and 7YH are your front shock codes.

Came across that nugget from a tire engineer's website, it's their industry standard so I adopted it. I tested it with my stock size tires and the 35s on the Sierra and it was perfect. Thanks for the compliment! I rarely get feedback and wonder if folks thought I was nuts!

Good man! Keep us posted and consider taking photos/video and doing a tutorial if you are so inclined.

You'll be fine, have at it!

Well, you can change all that in the calculator. On the left under "Tires & Wheels", you can change the tire size and the calculator will adjust. You can even track RPMs as the tires age and wear down by changing the tread depth. Under "Tires & Wheels" there is the transmission and transfer case calculators. The green field is where you enter the axle ratio and this will update the calculator to show your rpms in every gear at every speed. Right now your stock tires and 3.42 gears are turning 1,751 RPMs @ 70 MPH. Swap to the desired tires and you'll be turning 1,667 RPMs @ 70 MPH. Using the new tires with 3.73 gears and you'll be turning 1,818 RPMs @ 70 MPH. You will not be "straining" the drivetrain with the larger tires. You don't NEED to change the gears. The previous generation to yours, mine, ran 3.08s through 3.73s behind the 6L80. The 3.73s being reserved for the max towing package (NHT) in the pickups which some of the earlier models of your generation ran also with the 6L80.

They are not complicated at all. As long as you can physically do the work and have watched the videos it's easy peasy. Precision Transmission on Youtube has lots of MP3023 (yours and mine) teardown videos with lots of advice and how tos in them. Now, just to be sure, did you engage 4x4 on pavement or off-road? No 4x4 likes to turn on roads, especially parking lots. There was a software update way back when these were new that got rid of chain noise and slop, not sure if this applies to you or you want to go through the motions of a software update.

I made my own with excel. Attached is the file or you can ask me what you're wanting to accomplish and I can run the numbers. 00 Towing Calculator and GMT900 SUV Driveline Calculators.xlsx

I like it, front winch is cool, probably why they lifted it.

They is wrong! 45E1243 or 19365869 for the leaf spring bushings, 45E1242 or 19365867 for the shackle bushings.

Buy a Tech-2 to help you get this thing pieced back together. You'll also need a subscription to the shop manual for wiring diagrams at AllDataDIY. The Tech-2 can do pass through programming via a laptop if necessary. As the Tech-2 shows codes you can solve for them and move on to the next, provided you get power to the data link via the fuse that powers the cigar lighters.

Yes, but it will ride like crap. The front suspension on most pickups is rated for 3950 and the Yukon XL is 3600.

My motor was more noisy running Mobil One oil than it is now running ACDelco's Full Synthetic. Analysis of the oil showed less wear too. An exhaust leak, depending on where it is, can sound like a bad lifter. If she sits a lot, consider putting a battery tender on it to keep the battery charged up and conditioned.

Buy a Tech-2 ($300-$350) so you can work on this truck if you intend to keep it. Combine that with an electronic subscription to the shop manual at AllDataDIY and you'll have the same tools a dealership has. This will allow you to properly diagnose problems and decide whether or not you want to do a repair yourself or farm it out. The CAI could have thrown off your numbers without the tune, it takes time for the computer to adjust, most of them are worthless as the stock airbox flows more than enough air for even a 6.2. How many miles on the truck? How many miles on the oxygen sensors? Sensors over 100K miles, even if working perfectly fine, start to not calculate the alcohol content properly. Throw in an exhaust leak or two or off-brand sensors and it will never be right.

On June 17th, I paid $5.699 for Chevron's 93 octane gasoline in Stuart. On June 25th, I paid $5.369 for Chevron's 93 octane gasoline over in Tampa. On July 4th, I paid $5.359 for Chevron's 93 octane gasoline back in Stuart.
