Hi, I’ve got a 2015 5.3 litre v8 crew cab Silverado 4X4 with about 70 000 km on it and on 3 occasions there has been a loud bang coming from the rear of the truck when pressing the gas pedal to take off (after being parked). It’s only ever done it after being parked for a couple hours or overnight. Doesn’t do it when driving around stopping at stop signs or stoplights. Thought it was ice and snow build up at first because we have had mild then cold weather, but this morning when I pressed the gas the truck didn’t even try to move, which was followed by another bang and then the truck was fine. Only thing different I noticed afterwords was a very slight vibration on a section of road where there was no vibration before (but roads are kinda rough here, it’s hard to tell between road and truck vibration). The stupid truck was in the shop for an inspection 3 months ago so it’s not like I’ve been neglecting it. I’m trying to figure out what it could be in order to make the best call on whether or not to park it until I can get it in to get it looked at, which will probably be a week or 2. I’ve done a lot of googleing but can’t find anything making a loud bang-mostly just clunks. I don’t consider this noise a clunk at all. It makes my dog get up from laying down. It’s comparable to the decibel your vehicle makes when you hit a huge pothole and your first thought is oh ****. I had my previous truck until it was 10 years old and it had its share of clunks, whines and rattles but nothing like this. Have you had issues with the infamous driveline clunks, worn u joints, binding slip yoke, or broken rear diff parts? Have any of them sounded this loud? I got distracted from this post for a bit and was doing more googleing. Found 2 post suggesting it’s the rear diff. Not good. Any thoughts?
