Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about what factors contribute to vibration or wobbles in your vehicle system. Also on this show:

• How your car feels at different speeds and how that can help diagnose an issue with vibrations.
• How often vibrations are caused by your tires or alignment compared to engine issues.
• Fan blade problems that contribute to shaking.
• Information about misfires during acceleration.
• How your brake system could be causing unwanted vibration.
• 2005 Chrysler Town & Country: I’ve noticed my radio dropping out intermittently- followed by other electrical issues and warning lights. What is causing this?
• 2006 Nissan Sentra: I’m noticing a shaking while at a stop. I’ve taken my car into several shops and no one seems to be able to fix the problem. Where should I turn next?
• 1994 Chevrolet Cavalier: This car broke down after a loud knocking noise. We added oil, but the noise is still there. Is this possibly a hydraulic issue?
• 2003 Toyota Tacoma: I’m noticing a strong vibration during braking. Is there a shop you would recommend in Mesa to look into this?
• 2006 Hummer H2: I’ve had issues with my car overheating. After reinstalling the thermostat the issue went away for a while. Would you recommend a radiator flush?
• 2012 Ford F250: This truck is hesitating to start after sitting in the sun for a while. The dealership hasn’t been able to diagnose the issue. Any advice?
• 2001 Chevrolet Equinox: I have a severe shake during acceleration AND deceleration. Is this one issue or separate problems?
