Hi, I have a 2014 Sierra and it’s been making this really loud rattle every time I hit a bump for a couple years now. Would’ve had it fixed by now if it weren’t for all the other, bigger issues that constantly pop up. I’ve always assumed it was my leaf springs, so I went ahead and replaced all the leaf spring isolators, and also went ahead and added a few of my own. I have a total of 8 isolators on each leaf spring and it still makes the noise. It sounds like a crappy old boat trailer going down the road at this point. I assume these are the original springs at almost 200k miles, but the fact that they still make the noise even with the isolators leads me to believe it may be something else. I’ve hammered and wiggled everything under there, but the only way to recreate it is to drive. If I need new springs, I’ll do that, but I figured I’d check and see if anyone else has had this problem and how they fixed it. I was able to mount my GoPro and get it on video, here’s the link YouTube link to video
Just noticed that every time I back into a steep driveway that requires the rear suspension to articulate to one side there is a pronounced suspension clunk and bushing noise. This is a pretty extreme articulation even for a driveway, but was curious if anyone else has a similar noise. Suspension is Z71 on 20inch tires. No noise if both tires hit curb at same time. Similar noise is produced when exiting and turning making each tire descend the curb individually. Thanks!
