Driving with the severe misfire will destroy the cats in no time. I destroyed one driving about 20 minutes to my dealer with a severe misfire. I think it’s the unburned fuel that does them in.

I’d go kit. Issue I’ve had before is you have all these nice stainless pieces and when the shop welds it up they use non stainless weld material and the welds rust.

Vacuum pump?

If one quick chirp, it’s probably the flapper valve in the exhaust

Had my 2015 looked at last week for the valve chirp but since I’m 6 months out of the 3/36 bumper to bumper warranty, they wouldn’t replace it no charge. It’s not covered under the 5 year power train warranty. I was quoted $800 for the new exhaust. Figured I’ll clamp it open or put the $800 towards a borla/Corsa exhaust.

Cut a sheet of rubber from a tire inner tube and put it between the leaves at each end of the spring. This worked for me and others. If you do a search of my few posts I posted a procedure and some photos in one of the leaf spring threads.

Now that I look again, the pinned post is for 2014; this one is for 2015 but appears to be the same software patch fix

I’m blind. There’s a sticky for 2014. Please delete

Didn’t see this posted anywhere else. Not sure why it’s 2015 only....

As hokey as it is, the rubber inner tube between the leaves works to eliminate the noise. I 100% agree we should not have to do this crap. I mean Leaf springs have been around for what? 100+ years and they’re not complicated.

Keep us updated on how these hold up. I usually use raybestos advanced technology but the RPT are half the price. You’d think the coated ones would be more expensive.

A tech2 is just a bit more advanced than your run of the mill obd2 scan tool. You need bidirectional tool and I believe on 2014 and up, tech2 does not work.

They’re basically a toggle bolt design where as you tighten it, the 2ears flatten out against the inside of the bed panel
