I have a 2005 Dodge Ram Quad cab. I haven't driven it much since getting my Camaro earlier this year. It has mostly been sitting my garage. I changed the oil today and took it for a drive.
What I noticed
- About 35-45 miles per hour, there is a vibration. It's not uncomfortable but still unpleasant. Low frequency.
- Around 45-65 mph, rides pretty smooth (like a truck).
- Over 65, slight vibration. High frequency.
My uneducated thoughts and facts
- I had new tires installed a few thousand miles before storing but never got an alignment. Would an alignment help?
- Do these issues sound like the tires were flat-spotted and it will go away with driving? The tires were all down to about 20 psi and I filled them to 35 psi before driving.
Any other thoughts? I'm just trying to come up with a place to start.
