Well you may have a bit more angle but that's not your problem. Plenty of guys run close to 10" of suspension without modification to the drive shafts. It's your gears or gear setup. The shop knows this...I guarantee it.

 

This issue is common with the Duramax and 263hxd...maybe not half tons tho

 

Blackout probably right.

I'm just gonna take yalls advice and go to another shop, I'm sure they will diagnose it correctly cause they want my $.

 

In this case the other shop is the stealership. Oh well, its coming up on winter and I'm gonna need 4wd regardless. Just want this over with...

Took it to the dealership and they told me its the front diff causing the issue. Guess its time for warranty work and if the other shop won't do it I'll have to drop the cash for the dealership to do it

Make sure you update us with what the shop that did your install has to say, along with as many posts on as many forums with their name and address to adequately warn others to stay away if they don't get with the program.

Took it back to em just now and told em what the dealer said. No questions asked just took the keys and told me they will pull the front diff. and let me know what's wrong, whether its bearings or gear set.

Well, they didn't do anything. Im furious right now. Called me yesterday (Friday) and said "Oh I looked it up and there a bunch of people that have problems with the auto trac transfer case and lower gears" so I looked it up on google and found my topic and a couple others, but those pertained to the tcase blowing up. Blackout, I know you have the same tcase and you aint got problems. And if I have bigger tires to reduce the RPM's so it stays at factory speed, I don't know how that would make a difference versus the STOCK trucks with 4.10's (that's what my RPM's are equivilant to right now)

 

The guy said if they pull the front diff. and don't find anything wrong then they have to charge me full price. I said eff that and went and picked up the truck. So I think I will pull it myself and take it to the dealer to get this shit over with. Im tired of screwing around, cause Im gonna need 4wd coming here soon. Im just going to buy a new gearset and bearing kit and have them rebuild it with those and see what changes. That means my truck will be down about another 2 weeks.

 

I completely doubt they will "see" anything and want to charge me anyways, so Im done with them and wasting the money at the only place that tells me any truth around here. Guess I should have just stuck with my gut feeling and taken the IFS diff. to the dealership in the first place. Cause now its gonna cost me the $400 for the first rebuild and now probably $600 for this one, plus a new gearset and bearing kit, just to be safe.

 

Anyways, sorry for the venting lol

Its okay man, live and learn. My front diff in my 05 blew up because I had the axle seals changed.... First time was fine and they laughed a bit as my diff wasn't leaking bad yet and I never lost noticeable level but paid to have them swapped. 6 months later leaking again so warranty repair.... and within the first few hundred miles after picking it up it was howling in 2wd..... I regeared the truck to 410 from 373 ( big difference on something heavy with an 80e) and just bought a low mile used diff this time. I had a guy look inside and do seals but he was a GM tech that was excellent for around 20 years who went on his own.

 

If you aren't careful they are easy to bugger up. I just don't like doing the 9.25" in particular myself as the drivers axle shaft seizes in the spider gear forcing you to split the diff.... hence why axle seals became a killer for my original.

 

My original shop that wrecked my diff didn't compensate me either nor would take any responsibility.

 

Hopefully you get it fixed properly and your truck is done this time!

That's some really crappy customer service right there. Those crooks know damn well what the problem is and that it started after the gear install. The gears are whining loudly because either it's a poorly machined set (this happened to me) or they didn't set them up right. I can't imagine that they didn't change the bearings when they installed the gears so I seriously doubt that's the problem. You should post up everywhere warning people to stay away from that shop.

 

When my first set whined i went back to the shop the next morning. Told them what it was doing and they went straight at it without hesitation because it was pretty obvious what the issue was. They even outsourced the job to another shop since they didn't have the gears needed, just to make it right ASAP. Those guys your dealing with need to understand that that is the level of customer service people expect these days. Have you run your concerns up the chain in hopes of getting this handled?

I talked straight to the manager or owner (not sure where he is in the chain of command) of the shop and all he does is agree with the mechanic and basically believes whatever the mechanic tells him. They do not have a shop foreman I believe. When I went to my dealer, they let me speak directly to the shop foreman in regards to the problem. We have bought quite a few vehicles and numerous parts for work trucks and my truck there so I kind of know a lot of the guys there, and they know when I bring my truck in, its either for an alignment or there is something seriously wrong lol

I should take them there because the first diagnostic they did were bad wheel bearings. Me knowing they are original to truck (345k) I replaced them and noise persisted. That's $400 right there. And then they said transfer case. Already had one, so cant really do much, except for the coupler gasket, output shaft seal, and auto-trak II fluid, so bout $100 there. They I paid them an hour rate to diagnose it, when they said tcase ($100) and then the dealer spent two hours looking at it ($160). So that alone is $760 I didn't need to spend. That is a fresh rebuild at the dealer right there!!! If I brought in my own bearing kit and gear set of course...

As far as removing the front diff, so I don't get charged for that labor, I have to:

 

remove front tires

remove driver side torsion bar and kicker brace

remove both CV shafts

remove driver side shock

remove two bolts holding lower control arm on

Move that whole knuckle/ control arm assembly

and then I can get to the lower bolt that holds in the front diff.

and also remove the upper driver side bolt, and the two passenger side bolts

and "wallah!" there is the front diff.

 

Shouldn't take but 2-3 hours at a nice leisurely pace if I "Grab Some Buds" sorry I had too lol

If you haven't paid them yet, don't. They screwed you over, now it's your turn. Maybe they'll think twice before they do it again.

I already paid them. They were loose differentials and installed them in the truck myself. This has been going on like 4-6 weeks now

      Low fuel pressure after installing new fuel pump

      Low fuel pressure after installing new fuel pump

      By Gilkey96 · Posted

      Hello, first time posting here. I have an 03 Chevy 1500HD with the 6 liter gas engine. The truck ran fine until the fuel pump died on me and had to get it towed. Replaced the fuel pump with a precision pump from O’rileys and changed the fuel filter while I was there. The truck will run and drive now but it wants to idle around 500 rpm when in drive and it tries to stall if you touch the gas. It drives fine though, just doesn’t want to idle. Put a fuel pressure gauge on the rail and only have 50 psi. I guess these trucks should have 55-62 psi to run right. I thought the regulator might be the issue because when I would unplug the vacuum hose it jumped to 56 psi. Replaced the regulator and no change. The only thing I can think of is that I was sold a faulty fuel pump. Any help would be appreciated because I’d rather not have to take the bed off again if I don’t have too. Thank you!

      AFM Experience

      By diyer2 · Posted

      I've been wrenching on GM trucks for 17 years. And I need to get something off my chest because it's been weighing on me for a long time. After all that time, all those motors, all those people standing in my bay, I've figured out there are really only two kinds of owners. The ones who already know about this. And the ones who are about to find out the hard way. A guy came into my shop a few weeks back in a 2018 Silverado 5.3. Sharp guy, maybe 35. Knew his truck cold. He'd been on the forums, read the threads, done his homework. He only rolled in so I could double-check a little module he'd already plugged in himself. Wanted a second set of eyes on it. Ten minutes, in and out, drove off happy. Two days later, a completely different story walked through the same door. Older fella this time, in a 2016 Sierra. Gorgeous truck, clearly babied, not a scratch on it. Wedding ring. Looked like a guy who took care of his stuff. He was in because his engine had started knocking on the way to work. And by the time I got the valve cover off, I already knew it was too late. Lifter collapsed. Cylinder 5. Camshaft chewed up. The whole top end shot. Same kind of truck. Same motor. Same roads, probably the same dealer. The only thing separating those two men was information. I've been at this since 2008, and I've worked on everything GM puts out. Silverados. Sierras. Tahoes. Yukons. Suburbans. Escalades. The 5.3 and the 6.2. Doesn't matter which badge is on the tailgate. They all carry the same problem. So here's the information one of those guys had and the other one didn't. It's called Active Fuel Management. AFM. GM started building it into their V6s and V8s back in 2007 to squeeze out a little better mileage on the highway. Maybe a mile or two a gallon. All to hit government fuel economy numbers. The way it works, the motor quietly shuts down half its cylinders when you're just cruising along. And the little lifters that pull that off have a tiny pin inside them that's constantly clicking in and out. Lock, unlock, lock, unlock. Hundreds of times a drive. Thousands of times a week. Eventually one of those pins wears through. The lifter drops. And it starts grinding the camshaft down like a chisel on butter. And what nobody tells you is that the shudder you feel around 40 or 50 mph? That's the system cycling. Every single time. Here's what really gets me. The pre-2007 trucks, the ones without AFM, they're bulletproof. I've got customers still daily driving them with 260,000 miles on the odometer. Not a problem in the world. GM took a perfectly good motor that would have lasted a lifetime and bolted this system onto it. And it is wrecking engines that should have run forever. The guys who hang around the forums already know all of this. So do the techs. They handled this years ago. They didn't sit around waiting for the dealership to mail them a warning letter, because that letter is never coming. It's the guys who figured somebody would've told them who end up on my lift. And I want to be clear, because this part matters. Maintenance has nothing to do with it. I've torn down motors with barely 30,000 miles on the clock. I pulled apart a Tahoe last summer with 24,000 on it. Practically a brand new truck. Owner had it less than a year. Spotless oil. Best synthetic money can buy, changed early every time. Made no difference. I've seen guys with full dealer records, every interval stamped. Made no difference. The oil changes were never the problem. The pin was. And no amount of babying that truck stops that pin from cycling every single time you drive. That's the part that eats at me. These are good motors. Take the AFM out of the equation and a 5.3 or a 6.2 will run 300,000 miles and never blink. So a few years ago I started telling every single owner who comes through my doors the exact same thing the smart guys already knew. Get yourself a FullForce disabler. It plugs right into the port under your dash. Couple of seconds and you're done. It just tells the computer to leave every cylinder running, full time. No more cycling. No more beating those lifters back and forth every time you turn the key. It doesn't reprogram anything. Doesn't touch your tune. And unplug it before a dealer visit and there's absolutely zero trace it was ever installed. I've had customers come back at 40,000, 60,000, 80,000 miles after I put one in. Zero issues. The trucks run smoother. And the lifters aren't getting beaten to death every single drive. I won't sit here and tell you it's magic. A lifter that's already damaged is a lifter that's already damaged, and this won't un-ring that bell. But it takes away the one thing causing all that wear in the first place. That's the whole game. You don't need a five-thousand-dollar delete. You don't need an expensive tune. You don't need to tear anything apart. You just need to stop the cycling. I'm not writing this for any company. I'm writing it because I'm tired of watching the guys who didn't know pay four and five figures for it. I'm tired of being the guy who has to break the news. I'm tired of knowing that the guys who did know fixed the whole thing for the price of a tank of gas, and the only difference was that somebody told them first. If you drive a Silverado, Sierra, Tahoe, Yukon, Suburban, or Escalade from 2007 or newer with a V6 or V8, you've got AFM. You've got those lifters, and they're cycling every single time you drive. So be the guy who already knew. Not the one I'm scraping metal out of next month. EDIT: A bunch of folks asked, so here it is. The one I put my faith in is FullForce. This is where to find it: https://www.tryfullforce.com/products/fullforce™-afm-dfm-disabler They back it with a 60-day guarantee too. I've handed out more than I can count and not one's ever come back to me. Not one. See less

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Thanks for following along. I'm not author material, my tenses are all over the place and an editor would have a heck of a time cleaning up after me. Reading and writing is still a fun pastime though.   My new scanner came in yesterday, wow, where the heck has this thing been?! It connects right up to the Blazer, there's all kinds of bidirectional tests like EGR activation and percentage, toggle the fuel pump relay, EVAP purge valve, IAC control, AC relay, reset the transmission's adaptive learning, toggle shift solenoids and TCC lockup, and I can reset fuel trims with the click of a button...all things I could have used over the last 60 days!   It's also telling me there is a stored code in the ABS module for front left wheel sensor open and something about the brake switch. The ABS dash light works. It illuminates normally during the self-test at key on/ start and that's it. I cleared the codes and will see if they set when I take it out later. That, and I'm going to get (hopefully) real data on timing and cam ******. The PID's are there.   I connected the tool to my truck...holy smokes. Newer vehicles make early OBDII vehicles look like 8-bit, pixelated, early Nintendo stuff. This? This is like wearing 3D virtual reality goggles playing one of those elaborate, cinematic video games with seasons and plots in comparison. There are SO MANY modules and SO MANY tests and SO MUCH data. There's a scanner sequence for filling the coolant...   End of the day, it's a tool with way more power than I need, but the versatility to do old and new is there (and I need an adapter to connect it to my OBDI Camaro). It will allow me to do the first pass of diagnosis when out-of-warranty vehicles need help, and it will enable more DIY maintenance like brake system bleeding, ABS bleed, etc. I probably over-bought here, but, mission is accomplished.   Enjoy your Sunday...I need to shut this machine down and go get ready for the week ahead.

      Which 2027 engine will you choose?

      Not that I've read, after all the issues they've had in the past I'm pretty sure they learned their lesson.
