whenever I lift my truck it makes a weird squel/screech I have narrowed it donwn to my air tank anybody have this happen to them? At first it was just the rear no it is doing it when I raise th front too.
I've heard about people with similar problems to yours in the past. The only thing that was determined is that there cvould be some harmonic noise that was caused from air transfering through the tanks.
I don't have a remedy or suggestion at this time to eliminate that noise. Sorry.
Mine does it also. But not only when i hit a switch. When my edc is running it will do it just not as loud. Also if you want some real nice check valves check out gravity-werx.com they have some nice brass parkers. The smc's are imo are cheap and not worth the price.
We offer check valves in 3/8"NPT and 1/2" NPT sizes. The thing that is killer about ours is the fact that they're a cone style check valve. That way the air now flows over a cone shape sealing valve rather then a flat sealing valve. We also had our check valves designed with that cone to be high flowing so you don't see very much speed loss. Here's a picture of how they look.
