Sorry if there's already a post about this but I can't find anything like it.
Ford transit custom limited 2015 43k miles
In fourth gear going 50+ mph the van shakes violently back and forth. Continues to do this into 6th gear. Only shakes while accelerating. Had the wheel re aligned, so it's nothing to do with tracking.
Does anybody have any idea what it could be?
Would it still be under manufacturers warranty?
Thanks alot!
