Feel, Hear, See, Smell 2f

  • Whirring from the front of the car that changes pitch with vehicle speed:
    Even though the noise is there at all vehicle speeds, it is the change in pitch as the car's speed changes that makes the noise most noticeable. Some problems will cause an extremely irritating sound while the car is moving at highway speeds. Some causes may or may not gradually develop, while others occur suddenly.

    Possible causes:
    1. Loose or worn wheel bearings: Adjust or replace wheel bearings as required.

    2. Worn universal joints: Replace universal joints.

    3. Damaged flywheel inspection cover plate.

    4. Loose fan shroud or bracket: Tighten or repair brackets as required.

    5. Faulty torque converter: Replace torque converter.

    6. There may be some internal transmission damage: Have transmission inspected and rebuilt or replaced if required.

    7. Differential unit needs lubricant: Fill differential to proper level with proper fluid type.

    8. The rubber of your tires may be too hard: Replace tires.

    9. You are using the wrong type of tire for the surface of the road: Use correct tire type.


  • There is a buzzing noise from the transmission:
    You notice a buzzing noise from the car whenever you start to move forward or in reverse. The noise is not there when you have the car in park or neutral, and it seems to go away after the car has been driven a while or when you are moving at higher speeds. The problem seems to occur more regularly.

    Possible causes:
    1. The transmission's fluid level is low: Fill transmission fluid to proper level.

    2. The fluid in your transmission is contaminated: Flush transmission fluid and replace transmission filter.

    3. You have an internal problem in the transmission: Have transmission inspected and rebuilt or replaced if required.

    4. Your torque converter is bad: Replace torque converter.


    Radio or Horn Not Working

  • Radio has a lot of static and sounds poorly:
    Every time you turn on the radio, you hear a lot of cracking, hissing and popping from the speakers. Even more so when you tune the radio to an AM station. The speakers work fine when you play a tape or CD.

    Possible causes:
    1. The antenna connection to the radio is loose or corroded: Clean and tighten antenna connections.

    2. The ground wire for the radio is loose or corroded: Clean and tighten radio ground wire.

    3. Noise from the engine's electrical system needs to be isolated from the car's body: Replace or install radio static suppressors.

    4. The antenna needs to be tuned (trimmed): Tune antenna.


  • Radio doesn't work:
    You turn on the radio and there is no sound or lights.

    Possible causes:
    1. The fuse to the radio is blown: Replace fuse.

    2. The wiring to the radio is disconnected or damaged: Repair wiring as required.

    3. The radio is bad: Replace radio.


  • Radio turns itself off and on:
    The radio turns itself on and off without rhyme or reason. When it works, it is fine and there are no unusual noises from the speakers. This may happen all of a sudden.

    Possible causes:
    1. The circuit breaker to the radio or in the radio is weak: Replace circuit breaker.

    2. The wiring to the radio is loose or damaged: Repair wiring as required.

    3. The radio is bad: Replace radio.
