What could be causing the vibration when I hit 60mph?The steering wheel vibrates as well.
Could be a lot of things, but I would check front alignment, tire condition and balance, and front end in general for starters. Try rotating the front tires to the back. See if that changes anything. It's a cheap way to troubleshoot something without taking it to a garage.
You could try taking it to any tire shop that does alignments and ask if it is possible for them to do a free alignment check. I work for a tire shop and we offer a free alignment check. It is up to you if you want to get it aligned after the check.
