Grunt

When I turn right into a ramped driveway or the like I hear a short "grunt" sound like a tire tread is rubbing. Everything is stock and I have looked closely for where a front tire might rub. Nothing. Could it be the differential? Never heard that on the 2012. My Corvette will do some popping from the diff when I turn short and it's still cold but that stops after it warms up.

Wonder if it is the slip joint for the driveshaft.

My rear diff will pop on a really tight turn. I have a LS.

Do you have a LS rear?

"Do you have a LS rear?"

Yes and I did drain the fluid, refilled and put a suggested additive in for limited slip when the car was new. That seemed to help a lot.

This on my truck sounds much more like a rub. Probably nothing to worry about anyway.

I get something similar on my '12 when turning right into a upwards sloped driveway or approach. To me it sounds like loose box or cab mounts.

I can hear rubber/door seals complaining a bit when driving into steep driveways where the frame gets torqued. That my guess, I think everything flexes a little.

It could be either of the last 2 posts. Maybe one of the rubber bushings between the frame and cab or frame and box. No worries, just an observation. You know how it is when switching to a new truck and everything seems quiet and smooth for a while. I'm sure more little sounds will surface.

Hi gang,

If your truck is making a new noise or something just doesn't sound right, you can always have your dealer take a look. Let us know what you find out and don't hesitate to let me know if you need some additional help.
