Turbo/wastegate actuator rattle!

Yea the tolerances are definitely too big. I’m sure they factor in some expansion room because you’d rather them move freely than bind. But it’s obviously not right to have as much noise as some of them make.

My other idea was shimming the rod with some very small shims, but that may still not do it

Im going to reach out to the company that makes them for my 4 cylinder and see if they would have interest in doing the same for Ram. If they can make money from that, they absolutely will kill it for the Ram platform.

I have a 2026 with 2600 miles on it. I noticed the other day when our remote started it and walked up to it, it sounded like a rattle coming from the rear. It almost sounds like a loose exhaust piece or something. The sound isn’t coming from upfront, it’s more in the back. It’s a rattle and it will come and go. Is this the same issue???

Different but we all have that one...its the butterfly in the exhaust that rattles....you will know the rattle coming from the front as it sounds like bad detonation....think a bunch of rocks in a tin can being shaken violently lol

There’s valves in the rear that can rattle. Easy test is to put your hand on them (with a rag or glove) and have someone else cycle the accelerator pedal in varying positions. If you still hear it, it’s most likely the front waste gate arms

You can pin those exhaust valves open but you will still be left with the turbo rattle

I haven’t noticed that turbo rattle yet. How do you pin those valves ?

 

[MurphNH]

You use a flat piece of metal and two band clamps per valve. Search oem exhaust flaps and I did a brief write up with pics here

Exhaust Options

Well love the truck, but they really missed the mark with the exhaust. I know that Corsa and Borla will be coming out soon. I just wished they would’ve given the option to close the exhaust off similar to how the raptor exhaust is.

I think it’s shitty metal they use for the rods. It’s the exact rattle that happens on the Turbo 4 from Stelantis.

The fix is a bearing on both ends and a rod made from titanium.

There was a bulletin to replace the c-clips in the rod to try and help, but didn’t do shit for me.

Muffler shop cut mine out. $100 bucks.

For those of you that have the actual "waste gate rattle", from the actuator rods themselves, , I have been able to eliminate 99% of it with springs just like the raptor guys were able to do . I experimented with spring placement, lengths, and tensions. The position, and springs in the pic are where I have the best results. The rattle on cold starts and slow/light acceleration is 100% gone. (cold start was where mine was the worst. Sounded like a broken sewing machine) I now only hear the rattle on deceleration from higher RPMS, like when you are in Baja mode and decelerate from like 4500 rpms and higher where the trans holds the gear vs upshifting, and even then the rattle is almost imperceivably.

Hey brother, 2026 RHO with 1k miles and I’m experiencing the same thing. The dealer told me it was “normal” and two other RHOs on the lot do it. I ordered the springs and I’m going to give your solution a try. Still working for you?
