Road Test Quick Checks
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2004 Mazda B4000, 2004 Mazda B3000, 2004 Mazda B2300, 2003 Mazda B4000, and 2003 Mazda B3000. However, it is still accessible from the selected car via links, so may be relevant.
- 24-80 km/h (15-50 MPH)
With light acceleration, a moaning noise is heard and possibly a vibration is felt in the floorpan. It is usually worse at a particular engine speed and at a particular throttle setting during acceleration at that speed. It may also produce a moaning sound, depending on what component is causing it. See SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - 40-72 km/h (25-45 MPH)
With steady to heavy acceleration or deceleration, a rumble-type noise is heard. It is very intense during heavy acceleration or deceleration and very light during cruise or neutral coast. The vibration is hard to duplicate with vehicle supported on a hoist, since the wheels are coasting free. For Propeller Shaft Vibration diagnosis, see SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - High Speed
With slow acceleration and deceleration or at constant speed, a shake is sometimes noticed in the steering wheel/column, seats, floorpan, trim panels or front end sheet metal. It is a low frequency vibration (around 9-15 cycles per second). It may increase when applying the brakes lightly. For high speed shakes diagnosis, see SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - High Speed
With slow acceleration and deceleration or at constant speed, a shake is sometimes noticed in the steering wheel/column, seats, floorpan, trim panels or front end sheet metal. It is a low frequency vibration (around 9-15 cycles per second). It may increase when applying the brakes lightly. For High Speed Shakes diagnosis, see SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - High Speed
A vibration is felt in the floorpan or seats, with no visible shake, but with an accompanying sound or rumble, buzz, hum, drone or booming noise. It will exist in all drive modes, but may vary somewhat in acceleration, deceleration, float or coast modes. In some cases, the driveline vibration is eliminated in the float mode. For Propeller Shaft Vibration diagnosis, see SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - Neutral Engine Run-Up
A vibration is felt whenever the engine reaches a particular RPM either with the vehicle in motion or while the vehicle is sitting still. It can be caused by any component from the fan back to the clutch or torque converter and by anything that turns at engine speed when the vehicle is stopped. For Engine Accessory Vibration diagnosis, see SYMPTOM TROUBLESHOOTING CHART - SUSPENSION NVH . - Noise and Vibration While Turning
Clicking, popping or grinding noises may be due to the following:- Cut or damaged CV joint boot resulting in inadequate or contaminated lube fill in the CV joint.
- Loose CV joint boot clamp.
- A component contacting the halfshaft assembly.
- Worn, damaged or improperly installed wheel bearing.
- Worn, contaminated or dry CV joint.
