Experienced mechanics share their insights in answering this question :
Hello – I believe the humming noise you mention in the right front wheel area is a worn front wheel bearing/hub assembly. If the noise is louder when turning left while in motion, that would confirm the diagnosis. I would recommend having the right, front wheel bearing replaced by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs. The clicking noise while turning the steering wheel may be a problem with the upper steering shaft in the steering column. Cadillac has issued a technical service bulletin for problems with the steering performance (# 232985). Check with your Cadillac dealer service center for more information on this repair.

How to Identify and Fix Common car Problems ?

Humming tire suspects include faulty wheel bearings and uneven wear on the tires. You can solve this mystery by: Having your vehicle`s wheel bearings inspected and serviced by a trained technician. Getting your tires rotated according to manufacturer`s recommendations.
The most common and most easily identifiable symptom of a bad wheel bearing is an audible one. If you notice a grinding or grating noise coming from your wheel or tire, take note that this is very likely caused by a bad wheel bearing—especially if the noise gets louder as the vehicle accelerates.
Roaring sound coming out of the tyre/wheel area: Typically, when a wheel hub assembly goes bad it`s actually the wheel bearing inside the single assembly that is damaged. This part will make a roaring sound, similar to a metal-to-metal grinding sound when the bearing is wearing out.
A bad wheel bearing will make a humming sound or a grinding, grating noise as it wears out. But a humming noise could also indicate problems with your transmission, differential, or universal joints, so it`s important to take a closer look or get a second opinion from a professional, if necessary.
A humming or growling noise.

However, this symptom is more often due to worn or damaged wheel bearings, a bad intermediate shaft bearing on equal length halfshaft transaxles, or worn shaft bearings within the transaxle.

You Hear Grinding or Clunking Noises

Loud clunking or grinding while driving may also be a sign that your front differential failed. What you`re hearing is the under-lubricated gears of your differential clanking and rubbing against one another. The noise will generally get louder as you accelerate.

Worn wheel bearings can make all kinds of noises, from snapping, grinding, and humming to the clicking and popping sounds under debate. Symptoms of worn wheel bearings include uneven tyre wear, wheel vibrations, and oddly performing brakes.
The most common symptom of a bad wheel hub assembly or wheel bearing is a rumbling, squealing, growling or chirping noise coming from the wheel or tire area of your car.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
Once you notice any sign indicating a bad wheel bearing, avoid exceeding 500 miles with that issue. A failing wheel bearing will increase your difficulty in driving. But with a high-quality wheel bearing, you can drive for another 1000 miles as per the estimate.
A worn wheel bearing can cause a howling noise. If you`re also hearing a rumbling noise when turning, then it`s likely a bad wheel bearing. You may also trace this noise to a loose pinion-bearing preload. It`s likely the case when you only hear the noise when decelerating.
Some of the most common causes of vibrations in the driveline are slip splines or U-joints being worn, components that are out of balance, misaligned angles or out of phase yokes, getting close to the critical speed range, or yoke ears that are not coordinated with the splines.
Reviewed by Shannon Martin, Licensed Insurance Agent. , it is unsafe to drive your vehicle. While you may be able to eke as many as a 1,000 miles out of a bad wheel bearing, ignoring the problem for too long can have serious safety consequences—including one of your wheels stopping without warning while you`re driving.

Humming noise coming from Right Front hub, click noise in the steering gear – What is the problem? 2004 Cadillac Escalade
ANSWER : Hello – I believe the humming noise you mention in the right front wheel area is a worn front wheel bearing/hub assembly. If the noise is louder when turning left while in motion, that would confirm the diagnosis. I would recommend having the right, front wheel bearing replaced by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

My 2003 ford explorer wont start up just get click click click click click click click click
ANSWER : If the battery is weak and the voltage is dropping to below 9 volts you will get the clicking without the starter turning the motor. Have the battery voltage checked and if battery cannot hold a load then replace it and clean the battery terminals and recheck system to see if it starts.

Slight vibration and a humming noise coming from steering column and the front wheels
ANSWER : Based on the symptoms you are describing, you may have a wheel bearing that has developed some free play and may also have dried out. This can cause both a vibration and a humming noise. If you have altered the size of the tires or wheels in any way and the tires are wearing improperly, this can also result in a traction control light, a humming noise, and vibration in the steering wheel. I would recommend having your truck inspected by a qualified professional to determine the cause of this issue. Consider YourMechanic as this inspection can be done from your home or office.

I hear a loud clicking noise on the drivers side by my tire rim when turning the steering wheel front tires vibrating as well.
ANSWER : A clicking noise on turning is very characteristic of a failed outboard CV axle joint. Sometimes, in such a circumstance, you can see that the rubber outboard boot is actually torn and leaking grease. If you see that (look behind the wheel toward the axle end), the axle for sure will have to be serviced. If you change the axle, be sure to install a new rubber seal on the transmission output side so that you do not have transmission fluid leaks with the new axle (a common mistake is to overlook that seal; if an old, left-in-place seal leaks after the axle is put in the job has to be done all over again). Vibration without actual shaking of the steering wheel "might" be related to the axle issue. On the other hand, such vibration could also be due to a failed wheel bearing, especially with over 200,000 miles on the vehicle and if those are the original bearings. If you were to need both an axle and a wheel bearing at the same time, and on the same side, that’s actually not that bad because the steering knuckle that holds the wheel bearing has to come off anyway to replace the axle. But, backing up here, the very first thing to do is get the issue properly diagnosed so you spend the minimum possible. If you want to obtain a diagnostic, please request a vehicle CV/wheel bearing noise inspection and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Lights come on and clicking behind steering wheel
ANSWER : It sounds like you may have an electrical short somewhere within your steering column. This may be related to wiring, the clock spring, or even fusebox issues. The fusebox is usually located under the driver side kick panel on most vehicles and therefore the short may exist there as well. I would recommend having your steering column trim removed by a qualified professional in order to inspect the circuitry that is hidden behind it.

This inspection should be able to detect any damaged wiring or shorts that may exist visually. If nothing is visually noticeable, the mechanic would then use a digital multimeter and check for resistance in various circuits in the area to determine where the short might be. Once the short is found, the mechanic would then be able to decide the best way to repair it. This repair may be as simple as wrapping some electrical tape around a wire to re-insulate it or as difficult as replacing an entire wiring harness.

Squeeking noise coming from front driver-side tire only
ANSWER : It is possible you have worn brake pads and the sensor is telling you the pads are worn down too far. Since you also had an ABS light come on you may have a bad bearing and sensor in that wheel. I would recommend have the brakes get a complete inspection and also have the ABS scanned for codes. You will most likely have a bad bearing assembly on the noisey wheel.

Loud humming noise coming from the right front tire.
ANSWER : Hello there, many different faults will cause a humming noise from the front tire of your 2008 Kia Optima. The most common would be a failing tire, wheel balance, wheel bearing, dragging brake pad, sticking caliper, or a CV axle issue. A qualified technician, such as one from YourMechanic, will be able to diagnose your humming noise and perform any repairs required to get the car back to normal.

Shuddering and noise from the right front tire area
ANSWER : Hello. The suspension system contains rubber bushings that help dampen the vibrations caused by an uneven road surface. Badly worn bushings or ball joints can cause noises and vibrations during vehicle operation. To have this checked, enlist the help of a professional mechanic to inspect your suspension and diagnose the shuddering issue for proper repair.
