Good Vibrations!
 

Hello all, Mr. Newbie here! I too recently acquired a 2018 Mustang GT Premium. I do have a question, I've been reading various "reports" online from other owners that also have had a similar issue - between 55 and 65 MPH I get vibration in the steering wheel. Some say it could be tire balancing, others say warped rotors, still others say it ended up (for them) to be a total driveshaft replacement that cured the problem. Anyone here have any similar experiences with a positive resolution to same? Thanks in advance for your input!

could be tire balance... Might swap front and rear wheels and see if vibration continues...

Yes, that is what I am hoping for. Off to the dealer soon. . . . . of course, reading "on-line" about this issue results in MANY posts about this problem and as stated, everything from tire balance to driveshaft replacement has been mentioned. Then, there is also the issue of the "type" of balance performed such as dynamic, static, road force, etc. so that just adds to the confusion. I'm going to have to leave it up to the dealer I suppose, and whatever balancing method they use and hopefully it'll get corrected. If anyone else has experienced this condition, feel free to weigh in as all input will be considered! Thank you!
