Feels Like a Rumble Strip at 21-24 MPH I used the search tool and could not find anything. I have no idea where to start looking on the car for this. I will be as descriptive as possible.
2008 Pontiac G8 GT
When driving at about 21-24 MPH, it feels like the rear wheel is going over a rumble strip.
This happens only when accelerating.
It is perfectly normal at 20 MPH and it is back to normal at 25 MPH
This happens in any gear. I have taken the car to that speed in 1st, 2nd, and 3rd gear.
Possibly irrelevant- Sometimes it does not happen AT FIRST, as in, the first couple miles of driving before the car is "warmed up"
I figure it can't be engine or transmission related because it is very specifically at that speed, having nothing to do with gear or RPM range.
Any help is much appreciated. Thank you in advance!
