Front wheel rattling when going over a bump

My sister was driving the car and she said she heard a loud bang. Now when I go over any bumps in the road the front wheel makes a rattling noise, any ideas what this could be
Experienced mechanics share their insights in answering this question :
Hi there:

It’s quite possible that the loud bang your sister noticed was a suspension component or wheel bearing being damaged. In most cases, when the front end vibrates while going over a bump in the road, it’s caused by loose suspension pieces that are either worn out or broken and need to be replaced. However, it’s hard to diagnose an issue like this remotely, so you might want to have a professional mobile mechanic come to your location and complete a car is vibrating or shaking inspection; so they can determine the precise reason why you’re having these issues and recommend the right repairs.

Rattling noises that appear when you`re driving over bumps, or on uneven surfaces, are often down to the suspension. These rattles can disappear once you speed up a bit or when the going gets smoother. The culprits may be the drop links (e.g. if they`ve snapped), worn bushes or corroded shock absorbers.
Damaged or Worn Control Arms

Worn-out control arms may cause the wheels to move out of alignment, which causes the vehicle to make the clunking as you steer the wheels on a bump. The damage may be extended to the body mount and cause the cab compartment to vibrate.

Worn shocks and struts often produce noises, and their state of wear should be obvious from a profound lack of damping, allowing noticeable rocking and bouncing motions when the car is moving or a pronounced clunk whenever going over bumps.
A clunking, rattling, or squeaking noise from your front end while driving can be annoying and unnerving. Oftentimes, this noisy symptom means there is a problem with your vehicle`s suspension system. These sounds typically occur when driving over uneven surfaces, bumps, or potholes.
If you hear a knocking sound when your car is turning the corner, or hitting a speed bump, it could be because of worn out shocks that cause the car`s coil springs to vibrate against its chassis.
When the CV joint becomes damaged or worn, you may hear a clicking, clunking or popping sound coming from this area as the weight of the vehicle puts pressure on this area and shifts back and forth and side to side.
When the front (or rear) end of your ride starts rattling on smooth surfaces with barely any suspension movement, it`s most likely sway bar links. Most vehicles are equipped with a front sway bar (and many have them on the rear as well).
If you hear a rattling noise while driving, the first step is to not ignore it. The sounds and vibrations coming from your vehicle could be signs of a serious mechanical issue. Seek help from a professional who can find the source of the noise before any further damage is done.
If the engine mounts wear out, they cannot stop your car`s engine from moving around while you`re driving. When you press down on the gas pedal, your engine can come into contact with other metal components under the hood. This can result in a rattling sound from under the hood any time you accelerate.
When the brakes make a rattling or clicking noise, this is an indication that your brake pads need replacing. The rattling and clicking is caused by the vibration of loose components which damages the brake pad.
If a ball joint is beginning to fail, you may notice a clunking noise coming from the front wheels. This clunking noise will become louder and more frequent over time. You may also notice that your steering has been affected by the bad ball joint, potentially causing vibration in the steering wheel.
Unusual noises – When shocks and struts are worn out you may hear a clunking or knocking sound. This sound is caused by metal-to-metal contact when the shock or strut bottoms out when hitting a bump. In addition, these noises could be a result in worn shock or strut mounting components.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Front end rattle when going over bumps in a 2010 Milan Hybrid. Also drifts left noticeably on flat road. Are the two related?
ANSWER : The rattle could be due to a loose or worn sway bar, strut, body panel, or other suspension component. As you are describing it, the noise sounds fairly obvious so a mechanic should have no trouble pinpointing the origin on examination. The pulling is caused by misalignment and among the possibilities are too much cross camber. That is, inasmuch as your car pulls to the left, the camber setting on the left side of the car is more "positive" (measured in degrees) compared to the right side and the difference between the camber settings, left versus right (that is the "cross-camber") exceeds 0.5 degrees. Excessive cross caster could also be a cause, as well as a vehicle thrust angle that exceeds 0.5 degrees, side to side differentials in tire inflation pressure, tire faults (belt separations) and so forth. What I would suggest is first schedule an inspection to get the noise resolved BECAUSE to perform an alignment check, and do an alignment, there can be no faults in the suspension. Consequently, if the noise turns out to be due to a loose or defective suspension part that must be fully resolved before the alignment can even be accurately measured. To schedule an inspection of the suspension, please request suspension diagnostic – noise and the responding certified mechanic will get this taken care of for you.

Rattle sound coming from the front suspension over bumps?
ANSWER : Hi Cory. I watched the video, but it was very difficult to pinpoint a unique rattling sound that wouldn’t possibly be caused by driving on the gravel. In some cases when you drive on rough roads, a rattling sound will not come from a suspension component, but perhaps a loose exhaust bracket or perhaps a loose bushing somewhere. It might be due to a loose motor mount or steering stabilizer bar bushing – but without completing a car is making a noise inspection at your location, it’s really difficult for us to offer any additional advice or ideas.

Do I need to replace the hubs to go back to factory wheel bolts.
ANSWER : You’re wise to go back to factory fasteners. While there are a few good quality aftermarket products out there for your car, most of the options are a kind of one-size-fits-all that involve spacers and adapters that change the design offset and lead to all kinds of suspension and wheel bearing problems. you should not need to replace the hubs as long as the threads are not damaged. It should be possible to extract the studs through conventional means. If a hub IS damaged, then there is no choice but to replace it. This will involve replacing the wheel bearing as well so it can get expensive. If this project is more than you want to take on, you can contact Your Mechanic to have a technician come to your home or office and change out your wheels for you

When I put my car up on the jack and the front wheel comes up and I go to loosen it the wheel hole wheel moves left to right like
ANSWER : What you are describing sounds like free play in the tie rods. Your car has enough miles on it for this to be a problem. The tie rods are the link between the steering gearbox and the front wheels and as they wear, they will develop a certain amount of free play. There are about six pieces there that can be replaced as needed to tighten things up again. You can contact Your Mechanic to have a technician come out to your home or office to check out your front end and advise you on which pieces need to be replaced. Don’t put this off too long. Eventually, a worn tie rod can separate, if that happens, you will lose control of the car.

If i supply both front wheel hub assemblies, what will the total installation cost be to?
ANSWER : Sent billing question to CS for installation of the front wheel hub assemblies.

Rattling noise from front left during left turns or while going over bumps.
ANSWER : Hi there. Base on the information you’ve provided this may be a result of the leveling kit installation. I would check the caliper on the left front and make sure the mounting bolts for the caliper and pads are proper tightened. Then check the installation of the shock to see if the nut is overtightened and squeezing the bushing flat; simply look a the top of the shock and see if the bushing is flat and allowing the metal washers to make contact. Also check the sway bar link for similar signs as noted for checking the shock. The last thing that I would suspect is a wheel bearing that may not have been properly tightened or may need to be torqued. YourMechanic has several technicians that can provide you with a proper suspension inspection for the noise and advise you further on repairs.
