Common Signs Your Drive Belt Is Misaligned Chirping can be due to misalignment of the drive belt, but could also be due to pulley misalignment, worn pulley bearings, worn belt ribs, contamination from oil, coolant, power steering fluid, brake cleaner, belt dressing, or other substances. Squealing is usually caused by slipping between the belt and the pulleys.

Sounds Like Trouble: A Quick Guide to Diagnosing Common Engine Noises Valvetrain Noise. Valve and tappet noise usually begins as a clicking sound, or chatter, at half engine speed and may then disappear at high speeds. The cause is often excessive valve clearance or a defective hydraulic valve lifter. To check your clearances, you can insert a thickness gauge between the valve stem and the rocker arm or lifter. If this reduces the noise, the cause is excessive clearance, and you’ll need to make the proper adjustments. If it does not reduce the noise, the sound may be caused by worn lifter faces or rough cams.

- Idle engine and short out each cylinder plug. The noise will disappear when plug with bad piston is shorted. Noise will also disappear at acceleration. This can be caused by worn or out of round cylinder, or broken piston ring.

What Are Some Symptoms of Worn Wheel Bearings? A grinding noise is most often an indication of a decrease in integrity and often occurs when there is a shift in the load or when the car is turning. If the rumbling noise is related to the wheel bearings, it usually worsens whenever the steering wheel is turned to the right or left.

Seven ways to pinpoint that high-pitched, whining noise One or more of these could be the source of the noise. Affirmative answers to questions 1 and 2 would point in that direction. These bearings could be in the alternator, water pump, power-steering pump or pulleys that tension and guide the fan belts and timing belt.

How to Eliminate Engine Noise How to Eliminate Engine Noise. Engine/Alternator noise sounds like a high pitch whining that gets louder and higher in pitch as you press on the gas pedal. This noise indicates that the system either has a bad ground, defective head unit, defective amplifier, bad RCA cables, improper installation, or a problem in the vehicle’s charging system. Follow the steps below in order to pinpoint the cause of engine noise and reduce or eliminate the problem.

- Our NordicTrack E5 si elliptical trainer has developed a squeaking noise when using it. The Model Number is XXXXX Based on the Exploded Drawing, the noise seems to originate in the area of the intersection of the Upright bar (part #10) and the Upper Body Axle (part #71).xpert: treadmilltech replied 4 years ago. from my experience with this unit it is usually #86 x 4 on part #1 and #93 x 2 that need tightened to stop the squeaking. if it is coming from the axle you may need to add grease and reassemble.

- 1. @Vibhor: Well, the pulley needs mass too. When the pulley has mass and friction, the force imbalance results in a net torque on the pulley (it cannot do so if the pulley is massless or frictionless), and is taken care of.

- A torque converter going bad makes the most noise when the engine is running and the transmission is in gear with the vehicle sitting still. If you move the shifter to the Neutral N position and the noise disappears, the case for a failing torque converter increases.

How Alternators Work One of the most common failures is bearing failure. The needle bearings that allow the rotor to spin freely inside the stator can break down from dirt and heat. When the bearings fail, the rotor will not spin efficiently and can eventually seize. Usually an alternator with bearings failure makes a loud grinding noise.If you suspect this problem, it's only a matter of time before the alternator gives up. Older vehicles with generators tend to require much more maintenance than newer models, but there's no hard and fast rule for how long an alternator will last.f you have a failing alternator, the voltage will be well below 14 volts. If so, it's time to replace the alternator. Before you decide you need to yank the alternator and replace it, make sure you check the serpentine belt. If the belt is worn or loose, the alternator won't function properly.

Diagnosing a noisy accessory belt drive Whenever a vehicle owner complains of under-the-bonnet noise, it is important to determine the type of noise and under what circumstances it occurs. A solution to a noise problem caused by pulley misalignment is not likely to resolve a slip noise problem that may be caused by insufficient tension. In any case, a noisy drive indicates a malfunction, and appropriate corrective action should be taken to eliminate the problem. Belt noise.

How to Fix Power Steering Pump Noise Power steering pump noise is one of the most identifiable sounds your car can make when it is broken. There can be a lot of clunks, squeaks or hums that can indicate a wide variety of other problems, but a whining power steering pump us usually very distinctive.

- Thank Jay. The noise you are hearing is the engine serpentine belt. The belt is turned by the crankshaft pulley and the belt will then turn the other accessories like the tensioner,v-power steering, water pump, air conditioner compressor and idler pulleys.

Symptoms of a Bad or Failing Drive Belt Tensioner 1. Grinding or squeaking noise from the belts or tensioner. The most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started. It is also possible for the tensioner pulley or bearing to wear out, in which case the vehicle will produce a grinding noise from the pulley. 2. Unusual belt wear. Another symptom of a potential problem with the drive belt tensioner is unusual belt wear. If the drive belt tensioner pulley has any sort of issue it can cause unusual and accelerated wear on the belt. A bad pulley can cause fraying on the edges of the belt, and in severe cases can even cause it to break.

- corvgreg. The sound of the lifters when the engine is running should help. If you here a distinctive tapping sound then you probably have solids. Some hydraulic lifters are noisy, though.Also. when adjusting lifters, tight to zero lash. If you can continue tightening the adjusting nut, then the lifter plunger is moving down.orvgreg.

Whining and Other Noises When Shifting Gears If when shifting into drive, neutral and reverse clunking noises are heard, a torque converter is often to blame. The torque converter turns while the transmission is in park and neutral, therefore any noise from converter problems will occur while in gear.

- I have found the grinding noise to be caused by either the power steering pump is low in fluid or a bad power steering pump. If you have a bad habit of turning the steering wh…eel all the way till you can't turn it anymore it will shorten the life of the pump.

- Drive the vehicle, making numerous stops and accelerations. If you hear a constant whining noise, accompanied by a slip in the gears as the transmission automatically shifts, it points to low transmission fluids. Without the proper fluid level, the pump has to push air through the transmission, which causes the noise and produces the hesitation or slippage. Any leaks on the ground will confirm a loss of transmission fluid. Sit in the vehicle with the engine idling and the shifter in park or neutral. Keep your foot off the brake pedal. Push the accelerator pedal, gently raising the engine rpm. If you notice a humming noise that increases in intensity as the engine rises in speed, it points to a malfunctioning transmission pump or pump shaft. Since the gear train has not been engaged in drive, it rules out all the other components.

- Noises once-per-wheel-revolution that only occur when you are pedaling are most often related to the freewheel or Freehub. The freewheel or Freehub bearings may be loose, or the cassette may be loose on the Freehub body.
