Squeal when cold

strokin20 · Apr 30, 2015

Hey guys, finally picked up a '15 Plati a couple months ago. It's got all the exhaust and intake mods. I've noticed lately upon my first start up of the day or when it has sat for a while, when I move the truck, I get an odd squeal that sounds like its coming from under the truck. I believe it to be drive line related because I can rev the truck up in neutral theres no sound. I don't notice it high speeds, only around 15-20 mph and under. As soon as I stop, the sound stops. I did some searching and found the threads about the transmission squeal, but that seems to only happen during a ****, which isn't the case with mine. It's not a brake pad or rotor kind of squeal either. I'll attempt to get a sound clip but it's not extremely loud either. Just wondering if anyone else has noticed this.

And just in case anybody was wondering what said truck looks like, I'll throw a few pictures up to show off the new shoes.

Does it have a egr delete? If so make sure it's not leaking exhaust at the block off plate. Sometimes a slight leak will squeal but will stop when the engine warms the leak stops.
