Fluttering noise and Steering wheel vibration at highway speed

[EngineDweller]

THanks man. Ill get it looked at today or tomorrow.

Getting tires rebalanced and getting it aligned this morning, I think the fluttering is a valve noise...but again, its so faint I cant pinpoint location, and its not constant. We will see. Cant wait to get this thing going right so I can start modding it!!! Thanks for the input guys, its greatly appreciated. Any other thoughts on my noise issue id be glad to hear it.

Rebalance and alignment helped with pull, still have slight vibration. Bringing it to a gm dealer this week to get the propshaft and engine mounts checked...warranty covers it all so I might as well get it checked out now.

Progress good! Let us know how things work out.

Tires are all good...got a bent rim tho. So ill have to wait to get the prop shaft and mounts checked until I get some rims.

A bent rim will cause vibes. They didn't find that when they first mounted your new tires and tried to balance them? (Obviously)

[EngineDweller]

Apparently not. Never had an issue at this place before. But they didnt even tell me til I made one of the techs go for a drive with me. And then hes like, well you have a bent rim...so I was like damn dude...coulda said something about that before I paid for an alignment. And yea hopefully its just the rim causing the vibration. Really dont wanna have to do engine mounts and prop shaft...its under warranty, but that would still suck. The vin is 9L1 so its most likely gonna have to be done tho
