I'd drown that noise out even at level 3 or 4, so not a problem. Ha ha. I'm kind of a pragmatic OCD. I don't take a vehicle in for service unless it's absolutely needed. So far, I haven't. This little issue doesn't remotely qualify as such. But like all other little nagging issues, like rattles, squeaks, misaligned parts, etc., I like to fix them myself . Have a great weekend gang.

 

I had mine replaced at 3k. Both sides from squeaking.

 

Just went through this on my truck. Even though the isolator is there it can still be worn/bad. Had a similar noise traced to right leaf springs. Purchased the new black isolators (originally had white but no payload package) followed tsb/workshop manual instructions for cleaning and install and haven’t heard a squeak since in about 5k miles. Worth a shot considering they were only a couple bucks each. The old ones were considerably worn!

 

Thank you for input. Since it worked for you, I'll definitely try those black isolators if the noise comes back, and can't find a way to add a layer of rubber. My only concern is breaking the plastic 'inserts' (or bushings) on the adjacent 'C' clamp when forcing the second leaf down to insert a new isolator. And that wouldn't be fixable without removal, by looking at them, but could be wrong. Does anybody know if you can replace those bushings without removing the spring pack? If yes, any instructions for that? Then I'd buy a couple of isolators and a couple of bushings, just in case they break.

By the way, with just 11K miles, I doubt the isolator is worn out. Maybe just defective, or broken where I can't see it. Or the second leaf's curvature out of tolerance. Wouldn't be surprised due to the multitude of glaring QC issues, but fortunately, it doesn't affect the functionality of the truck. Another detraction to get it replaced is you could get another bad pack, and it's such a minor issue I can perfectly live with the noise, even if I was unable to quiet it myself. Thank you to all for your great comments.

 

Step 1 of the instructions say you can trim the bottom of the isolator to make it easier to install.

 

Thanks. But I got that from the instructions. I was talking about the clamp that holds the 2 leaves together, which is like an inch before the isolator. It has hard plastic 'bushings' (or inserts, as I called them). The clamp is wider, so those bushings fill up the space to keep the leaves tight. I'm sure you know what I'm talking about. If you break one of those trying to separate the leaves too much, can you replace them? If yes, THOSE are the instructions I'd like to see . And maybe just remove the bushings first, so I can easily separate the leaves, then replace the isolator (or put rubber on top of it), and finally reinsert those bushings, and job done. Thank you.

 

My 2011 made the noise. I would add some thick grease twice a year. When my 2018 started I took to dealer since it was under warranty. Tech said he could replace the pads and it would start doing it again in a few thousand miles. Told me about this, I said I'll give it a try. So far so good.

 

Mine was the clamp that hold the leaf from twisting - a little anti seize on the outside were the leaf touches it fixed it.

Noise was from the side of it.

 

That "clamp" appears to be a non-serviceable item. That is, it is part of the spring assembly. A trip to the dealership parts department will confirm that.

 

this is 100% true. non serviceable
