well today I must pay for a Uhaul because they do not have any loaner trucks and mine is still in the shop. I did this before I went back to a truck so nothing has changed in regards to needing a Uhaul to move family members around. I have never considered another brand in truck and I have owned over 9 new GM trucks in my life but thinking this one has me thinking - customer service and product have evolved into something not appealing to me.

 

Think on my way over to the Uhaul lot I may look at alternatives just purely heart broken

Ok. Vibration and a drone at certain speeds they cant fix. Infotainment has quit twice and the instrument cluster is out now. Seat creaks when you go around corners. Still has the drive line clunk that has been in the GM for years they cant fix. Been in the shop too many times for too many days. Recall of catching fire fixed and rear sliding window regulator fixed. I have had it for 34 days. Cant enjoy driving at any speed. I think that covers it. I don't know when I get it back from the shop. Have loaner but making payments on the new truck.

I know the feeling. I have had a few bad experiences with trucks. Each a different brand. We want to trash the entire line of trucks when we have a bad one. There are other Sierra and Silverado's that will never have a problem.

Never have a problem? I would like to see one of those.

I have owned several GMs that never had an issue. In fact sold a 2008 Sierra a couple months ago with a 4.8 that had 270+ thousand miles on it and drove it to work every day without issue. Trans filter and fluid every 50K, oil changes every 5K, spark plugs at 100K then at 50K intervals after that because the first plugs looked too worn for me, and diff changes every 50K and the truck kept ticking along like a timex. This truck however I think is making me pay for the luxury of that truck.

If you had an AFM engine it would never have made it to that mileage without any problems. Probably not even half of that mileage. I am surprised that the transmission lasted this long.

I have two 2014's that I have not had a problem with. Never had a problem with my 2002, 2005 or my 2010. All Silverado's fully loaded out. If you want to go back as far as 1999 then I did have the power lumbar serviced on that Silverado. My first Silverado was a 1989 when they first started making the extended cab. No problems with that one either.

Hey Mike,

 

I had the bridgestones put on my truck this morning and it didn't fix mine either. I too am waiting to hear back from Jeff for the next step. I have a vibration in 8 cylinder mode and it gets a whole lot worse in 4 cylinder mode, and they want me to buy a $200 aftermarket module to disable the 4 cylinder mode...I don't think so, maybe they should fix their own problems!

can someone tell me why the 5.3L engine is now on restriction? Thought I may look into a high country build (different suspension) but the 5.3L from what I understand is on restriction

Well, I thought it was the tires, so I got a new set, and now even at 65-80ish I still get some kind of vibration. I look over and my passenger seat is moving/vibrating and its like in the floor as well and I feel it in my seat. So could it be the drive shaft out of balance? What else?

Seats vib is usually rear tires. Maybe not well balanced. Ask around and see if you can find a place that balances tires on the truck and hopefully can true a tire. Some big truck brake, front end repair shops do such. Ask around. If cannot find such have the shop recheck the balance. Then look at drive shaft, u joints etc...Lifted trks change the angles on drive shaft, may want to check that too.

Just so you guys know, I had my stock Goodyears replaced with Michelins. When I got the truck back from Elkins Chevy, it still had a horrible vibration above 65mph after 2 failed attempts on a traditional balancer, with 2 different brands of tires. I found that they kept adding weights to the existing weights that were already on the wheel. You guys need to be sure that ALL weights are removed from your wheels before the dealer adds additional weights to balance. I found a different dealership with a road force balancer and the truck is now smooth as glass with the Michelins and fixed in under 2 hours. It took 4 different balances, 4 trips to different dealers, 3 different balancing machines and 2 sets of tires before my vibes were taken care of.

 

Not that you should have to but you could also take it to a tire shop that has a road force machine. Point being: Just because your tires are swapped out, dont give your dealer too much credit and assume that they did their job properly and balanced your wheels correctly.

 

BTW if anyone is in NJ, the guy who runs the road force machine at Turnersville Chevrolet really does know what hes doing. He also took pride in his work, removed all my old wheels weights and even the glue. If your in the surrounding area and need a good balance it may be worth the trip to go see this guy.

TR, just saw your location. You are close enough to San Antonio to check out Southwest Brake and Alignment . Have been using for years, Trued and high speed balanced on the truck tires even last longer. Call early in the week and ask for Ted the owner. He is there crazy early. Once the tires are done, he can tell you if the drive shaft, u-joints etc. still have vib problems. If he ever gives this up I do not know what I am going to do, as Discount tires road force does not match this.

Read my thread. I have it all.

Took my truck in to dealer yesterday for the shaking and found the 2 rear tires were bad. Funny thing is that out of the 3 new tires they had in stock, only 1 was good wtf :confused: . I have to take it back to get the other bad tire replaced. Don't know what is going on with this issue, will see what happens.

    • I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.
    • An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
    • There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.
    • The only problem I have seen this cause is longer crank times. 
    • Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
