In this video we will be going through 12 things that will break on your 2014-2019 GM Truck. We will be specifically talking about many issues that have occurred on my 2014 Silverado as well as other common issues across the GM lineup for those model years. These sister vehicles include the GMC Yukon and Sierra as well as the Chevy Tahoe and Suburban. We have linked many of the solutions for these problems below under associated videos. Enjoy and please let us know of any issues that I have forgotten so we can make a part 2. Issues Covered: 1. 6L80 Torque Converter 2. 8l90 Shudder 3. Chevy Shake 4. Exploding Driveshaft 5.

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.
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, JK29
