Well I ordered all the parts this morning to do the rear axle shafts and brake job. Truck has 81,XXX miles on it. Factory pads are about gone. The passenger side axle shaft seal is back to leaking pretty bad. It was R&R'd at 16k and has been sweating ever since and the dealer didn't want to hear it. 9 months later when I bought our new Enclave, I made sure I didn't step foot in that dealer. Anyway, I've also had the driveshaft balanced by a local shop which helped out quite a bit. All but one person who I've found did Yukon shafts said it fixed the vibration. So for $260, worth the old college try. Parts list en route are....
-Yukon Axle Shafts
-ACDelco Wheel bearings (both sides)
-ACDelco axle shaft seals (both sides)
-GM Diff cover gasket (yes I know its reusable but I've already used it once with my PML Cover and put silicone on it. )
-Raybestos Police package rotors. I read that these are mill balanced to a pretty good spec. Tolerances in general are much tighter.
-Raybestos hybrid ceramic truck pads
While I have it apart I'm going to do a gear pattern check, R&P backlash check at multiple locations around the ring AND check the pinion pre-load measurement. I read that one of these lemon buy back vibrators was donated to a tech school and upon disassembly the pinion pre-load was zero. Yes, zero. So i'm going through the axle my way.
What up fella's. I've been back and forth the past few months with my dealership in regards to the severe vibration I'm having on my 2017 Silverado Z71 Crew cab. The vibration occurs between 74-84 mph. It rides worse than the 2011 I traded for it. I feel it in the steering wheel, the gas petal, seats and center console. My main concern is it vibrates the hell out of my daughter in her car seat, which tears me up inside. There is no way we can take her for long drives in it as it makes her physical irritable and sick. Here's a video - https://www.youtube.com/watch?v=7giDNI70pTk&feature=youtu.be
Last time I took it to the dealership, they rode forced the tires and did a "pico reading" and dealership stated "it is operating within the specified range" and there was nothing they could do for me. Funny thing is I actually rode with the Service Manager and Tech while doing this test and both of them said they felt the vibration/shaking but it rides better than other trucks. Such horse shit.. This is one of many issues I've had with it since I bought it; FE: replace full exhaust system due to bad flapper, removed "rail dust" in paint, replace mass airflow sensor within first week of purchase, replaced "gateway module" which took 30+ days in the shop. I purchased the truck last November and am honestly depressed I'm even having this issue to which no dealership can/wants to fix.
Ive requested specifically requested to speak with a GM rep last time I was there which the service manager said ''I unfortunately don't know that info". You guys are my last resort, so I'm looking to see how I get in touch with the GM Rep to see what options I have before I get with a lawyer. Any help you guys can provide is greatly appreciated.
I’m working with a Chevy dealer in central Maryland on a purchase of a 2016 Silverado 1500, 5.3L, RWD. The dealer disclosed that it was a buyback. The salesman showed me the documentation and the listed reason for the buyback was “outside temperature gauge not accurate”. I’m worried that the listed reason may be bogus...that seems to be a minor nit and not worthy of a buyback. I plan to request the full service records and copies of the buyback paperwork. The Carfax is linked here
The dealer is reputable and we’ve purchased from them before. Any takes on what kind of situation I’m looking at here? Thanks for your opinions and advice.
I want to apologize in advance for the length of this... I just need to point out the details. It’s time GM does something for us who own 2014-2015 models, trucks I’ve dubbed "the engineering guinea pigs" thanks to personal experience and the myriad of complaints in this forum.
Good day to all of you. I’m presenting you an issue that is causing more concern to my safety in my truck than holding a gun to my head. Starting this off by stating I made the grand mistake of taking my truck in to get the steering update instead of checking ground connections myself. Doing this update bit me in the ass within a week of getting my truck back. Let’s just say that after I received my truck from the dealership in far beyond worse condition than I sent it in with, I’m getting consistent and far worse problems after updating. My truck shut off on me completely, losing control of steering and everything, while approaching a red light at about 45 MPH...with my younger brothers in the truck. I took it to the same dealership that same day, and they weren’t able to do anything. I was beyond frustrated. I’ve never had any vibration at any speed until my service. Now I’m getting vibration at 70mph. When I lightly press the brake, I’m hearing a rotational sound coming from my left front wheel, my mechanic says it’s the bearing but with our trucks having sealed bearings, I’m going to be looking at an $800 hub assembly. Just this Saturday, I made a 45 minute drive up to Ft. Lauderdale and as I arrived, I noticed my engine was producing a sound almost like a lifter noise, even though the dealership serviced my lifters(or one specific lifter, not clear at the moment as to what it was). When I got back in my truck after a few hours, I had no lifter noise...WTF? This is getting out of hand.
Here's the part that has me worried: ever since my update, my volt meter is below the half mark all the time (never happened beforehand) and I noticed that my headlights flicker and dim, along with my dash lights sometimes. When I press my brake and use my turn signals, the lights dim significantly and brighten back up but flicker. With my turn signal, my headlight dims when I engage it and as it blinks, my headlights dim and brighten with the blinks. Just the other day as I was backing up out of my buddy's house, my backup camera froze and I got a "service rear camera" message on the display. I’m so confused, how does an update manage to mess up my truck? I'm beyond pissed. The only good this update did was actually improve the shifting slightly, even though I’m still having that infamous 1st to 2nd rough shift. Other than that, this update makes me want to tell GM to F-off and move onto ford or something. Yes, I’m that serious. I’ve been a Chevy person all my life, the majority of my family owns Chevy's... this is just getting out of control. I've searched up all these forums about this and haven’t found too much. Already have links saved and screenshots of individual posts about all this, but I need more insight.
Did I make the mistake of buying a first-generation truck? I’m not looking forward to pursue legal action, which will end up costing me an arm and a leg, on top of that I probably won’t benefit much from it. Realistically, I’m also not looking forward to switching sides just yet. I want to make sure I’ve exhausted all my efforts before I make a drastic change like that.
This was my dream truck... and I was beyond blessed to be able to own it, and I had so much plans for it. Now? It’s looking like a nightmare, and I've got the urge to get rid of it.
HELP. ME. PLEASE.
I have a 2016 Silvarado LTZ Z71 4x4 with the 8 speed... About 13,500 miles on it and it's started to develop a "shudder" and it's been shifting harder. On cruise control it will shudder at around 1300 rpm with speed staying constant. I've driven it in manual on new roads at 35 MPH and it also shudders around the same RPM range. We're talking about vibration enough to shake the steering wheel. Almost the same effect as driving over bumps in the road. When driving it very aggressively at higher RPMs the issue isn't as severe. Also when drifting, aka letting the vehicle decelerate, the issue goes away.
Has anyone had the same issue with the 2016 8 speed? Any solutions?
I'd like to have an idea of what the problem is before going to the dealership tomorrow. I bet $100 they'll tell me it's the tires....
Thanks for input,
