2017 suburban squeak

[Mercracing]

I’m having an intermittent squeak coming from what I think is the RR. It’s most noticeable when I back up my driveway, when I hit the transition from road to curb and curb to apron. Small bumps at slower speeds. I’ve taken off the front and rear sway bars but that doesn’t seem to be it. Anyone else with this problem or thoughts?

Thanks for your time.

Haven't been around in a while, partly because I haven't heard anything new in the 4 yrs I've had my truck.  If what you hear is a dull squeak, I believe it's some component in the Premium Ride suspension, if GM still call it that.  I've had that sound in my truck since day one when driving in similar conditions as you describe.  I personally believe it's in the shock with Premium Ride being to soft, but when I lift the truck and look at the under-carriage, everything looks good.  For me, I don't consider it a problem.

I found the problem last night! On the drivers side just in front of the drive axle is a bracket that holds the two park brake cables. One of the cables has a soft clear plastic cover on it. It’s that soft plastic rubbing on the metal hanger that was making the high pitched squeak. I’ll find some loom to cover both cables so they are not rubbing on the hanger.

Good find and maybe this will help someone else with the same issue.

Yeah, that's a different squeak than what I was talking about.  Good catch though
