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 identifying the noises your car is making and how to describe the problem to your auto technician. Also on this show:

• When I coast or let off of the gas, the noise my car makes gets louder. What could this be?
• I have a strange noise coming from my vehicle but when I take it in to the auto shop, it doesn’t make the noise anymore.
• 2002 Honda Accord: When I put the car into drive there’s a whining noise when the car shifts from gear to gear. What is this?
• 1977 Chevy 350: I recently had a transmission put in and when I put it in reverse there’s a thudding noise. I’m not sure what the problem could be.
• Mazda 3: When I get to 30-40 mph I hear a noise and when I turn the wheel, the noise gets worse coming from the driver’s side. Could there be a problem with the wheel bearing?
• 2005 Chevrolet Cobalt: The front end of my car started shaking really bad on the freeway but then less below 50 mph. My mechanic says I need tie rods and a high speed tire rotation. Do you agree?
• 2004 Chevy Silverado:  The air conditioner in my truck will randomly switch over to heat while I’m driving.
• 2014 Chevy Silverado:  The fuel pump is very noisy. Does this have anything to do with the fuel injection?
• 2006 Cadillac 36,000 miles: I’m noticing a knocking noise when the wheel turns. Is this an alignment issue?
• 1999 Suzuki Grand Vitara 134,000 miles: The passenger window has a delay when trying to go up and the driver’s side window gets stuck in one position. Is it worth fixing and keeping the car or should I buy a new vehicle?
• 2002 GMC Yukon:  What does it mean when my ABS light goes on?
