2019 C7 GS vibration
HELP: A month ago I had the tranny fluid flush on my 19 GS and it seemed to shift fine and still does. Soon after I noticed a vibration that was almost like a harmonic sign wave that takes place every every 1-2 seconds apart and has become quite annoying. I took it to my regular tire dealer and he said I had tires out of round and a bent rear wheel. I had the wheel straightened and bought 4 new Conti tires and had the 4 wheel alignment done and still have the vibration. Any help,would be appreciated before Imtake it to a Chevy dealer 1.5 hours away. Thank you! Jim

I just had 3 bent wheels replaced under warranty by the dealer on my '19 GS.. had the same vibration you described.... much better now but not perfect...I'm thinking one of the new wheels is likely bent a bit as well....I may go for a road force balance...

thanknyou for your thoughts. I will have the wheels inspected and balanced by the dealer on Thursday. I will check on wheel replacement. I also wonder if it could be the drive shaft out of balance. Any one have any thoughts? Thanks
