Awful creak when flexing.

Skidsareforkids · June 19, 2017

My '17 Denali has 6,500 miles now, and whenever there is any kind of flex on the chassis it makes a horrific creak noise. Backing out of my driveway every morning it's the first thing I hear, and coming home at night too... It's driving me nuts! Any ideas?

Any suspension mods?

Whether this just started or if you've had it since new, take it in for service. I'd be very concerned if my truck made loud noises while backing out of my driveway. I wouldn't make any attempt to fix it myself as this is a new truck covered by a bumper to bumper warranty!

Most likely the leaf springs. Mine got really bad by 11k, the dealership greased them. Starting to come back at 21k.
