2017 mustang gt the rear end is moving or jerking left and right as I'm driving straight down the highway wet roads make the problem worse any help would be greatly appreciated

 

Welcome. I think I would be getting that baby to the dealer. That doesn't sound good at all.

 

Thank you I appreciate your support but I figured out what was wrong it was a wheel bearing only 5200 miles on the car it had me stumped for a minute

 

Good deal, and I happy it wasn't anything more serious. Unfortunately these things happen on mass produced cars. Every now, and then a bad part comes along.

 

I'd say it would have to be a really bad bearing for the back end to sway side to side. Hopefully that fixes it.

My car had a defective bearing that was replaced before I took delivery of it. It was found during the pre-delivery inspection...
