Yuck, this doesn't sound good at all. Stop using this truck until you find out where this noise is coming from.
Inspect the drive-shaft, look for faulty U-joints (you may need to drop the drive-shaft to see if one is binding), look at the gear-oil inside the drive-axle (is it full, does it have metal in it?), check for loose lug-nuts on all four wheels, check for cracks in the rims, and inspect rear E-brakes, They may be defective. Good luck, let me know how its going.

Hello. I hear a very loud thumping noise from the back of my 2014 Toyota Corolla as I slow down. I have taken it twice to the service station at the dealer and they hear the noise but cannot identify where...


Here are the only reason that can cause a thumping noise
  1. Wheel and Tire Problems
    • Wheels can become bent from striking objects, and tires can develop bulges from broken belts or wear. Both problems may cause a thumping noise. Thumping sounds caused by wheel and tire problems will typically increase in frequency at higher speeds, though the sound may not be heard at lower speeds. These problems can often be spotted by visual inspection.
    Suspension Problems
    • Worn or broken struts or strut mounts can create a thumping noise, especially when the vehicle hits a bump in the roadway. To test struts, bounce the rear of the car by forcefully pushing down on it and letting go. After letting go, the car should settle back to its original position without bouncing or noise.
    Loose Trim
    • Loose trim pieces near or in the wheel well can flutter in the wind while a car is being driven. These trim pieces may create a thumping noise as they strike other objects. A car owner can check trim pieces for looseness to determine if that is the source of the noise.
Hope this helps

Micra K13 Loud Noise at Higher Speeds


I've just bought a K13 Nissan Micra and it doesn't sound quite right. The noise I hear also seems to be coming from the back but it sounds like when you chop down a gear in a manual going down a hill and the engine revvs, well this is the noise I get in the automatic speeding up and slowing down, even just cruising at a steady speed. Any ideas people? Apart from this noise I love this car.

What is the cause of continual thumping (appears to be coming from back of car) and violently shaking?


Many times, rear tires that are out of round or severely cupped or feathered, or that are out of balance can create this type of issue. My first recommendation would be to have them and the wheels on the rear of the car inspected. There may not seem like there is much wrong visibly if you look at just the tread of the tires, but a good tire tech can spin them up and give you some solutions, and the inspection itself is inexpensive. Hope this helps.

4x4 low feature


The noise you heard was the 4x4 mode engaging. This noise is normal.

Under normal operations, if you were to have wheel spin, this noise would happen quickly and numerously within a couple of seconds.

Be sure that before going above 20mph, that you press either the 4x4 HIGH, or 4x4 AUTO buttons to avoid damage to the vehicle.

Engine revs realy loud


You have a faulty thermostatically controlled fan clutch. Same thing happened to mine. As soon as you start the car, the fan is always turning, and the speed increases as the RPM is increased.
