Low speed vibration - 30-35 mph

[dmichaels]

So I developed a fairly significant (in my opinion) vibration at 30-35 mph. It's not the engine cause it's there regardless of gear or even if in in neutral. I'm a bit list for ideas cause I've never had a low speed vibe before

I'd check hubs/bearings, front tire/wheel balance, and front alignment. Probably in that order.

Then check for build up on your rotors.

DMichaels:

By coasting your car in neutral, I agree that you have eliminated the engine. Now it's down to your rotating parts.

Where do you feel the vibration? 1. Is it in your steering wheel or brake pedal if you lightly apply brake pedal pressure?

Or, 2. is it more pronounced in your rear view mirror, or passenger seat that seem to vibrate a touch at 30-35 MPH?

If it's more towards item 1, then check your front wheels and tires, suspension, brakes, bearings etc. if it's more towards item 2. Then check your rear wheels and tires, axle bearings, driveshaft, etc.

Chances are it's a wheel/tire pressure balance issue, but start with the easy items first. Any changes to the car just before this vibration started?

Keep us posted and let us know what you find.

Good Luck,
