Hi there – if the noise is a roar that occurs even while on smooth highway, most likely your front wheel bearings are worn out, and need to be replaced. If these noises only occur when turning, or going over speed bumps, potholes, etc, suspension components are worn or damaged, and must be replaced. I would recommend a front suspension inspection 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.

Bad Tie Rods: Tie rods connect a vehicle`s steering rack to the steering arm. This helps translate the turning of the steering wheel to the direction of the tires. When a tie rod end is worn or loose, they may produce a clunking noise.
The most common reasons a Subaru Outback has a rattling noise are the ball joints, struts or strut mount, or a problem with the sway bar links. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
You`ll know when the axle is about to fail when you begin to hear a loud, rhythmic clicking noise coming from the front wheel as you turn. That noise is due to a lack of lubricant in one of the CV joints. A CV axle is a critical component of your Subaru, so it should be replaced properly by an authorized Subaru expert.
Squealing or Chirping
A high-pitched chirping or squealing noise that comes from beneath your Subaru`s hood indicates a problem with its belts. Belts are one of the most heavily used parts in a car, which causes them to wear down easily.
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.
That clunking noise you hear from the front end of your car when driving over a bump can be telling of an issue with your car`s suspension. More specifically, the problem is with your control arms or suspension system struts. This damage can occur if you are off-road or roughly going over potholes.
Your Subaru will have a recommended octane rating. If you fill it up with gas with an octane rating that`s below the manufacturer`s specs, you may hear a knocking or pinging noise coming from the engine.
A failing or dirty sensor can send incorrect data, resulting in too much or too little fuel going to the engine. This can result in a rough running engine that is louder than normal. Bad or Dirty Spark Plugs: Bad spark plugs can cause the vehicle to misfire which will make it run louder.
If you hear a whining noise from your car`s engine, it may mean much the same thing: there`s a component that`s worn out. If these parts break or wear down entirely, they could cause damage, so hearing a whining sound means that it`s time to schedule a service appointment.
The engine and road noise are a common characteristic of Subaru vehicles. This has to do with the engine design and the all-wheel drive system and I would guess a general lack on noise cancelling insulation. Not that you need a new car but the last Subaru I drove was much more refined and quieter than older models.
Besides brakes squeaking, the most common squeaks are usually associated with your vehicle`s suspension. The squeaking suspension parts are often associated with a lack of lubrication when metal-on-metal wear is happening in connections such as the tie-rods, suspension joints and steering linkage.
Some common causes for squeaking include faulty serpentine belts, power steering systems, brake pads, or suspension. Although you may ignore the noise, it`s counterintuitive as it indicates a problem with your vehicle. Leave it unattended for too long, and you may have a bunch of expensive repairs on your hands.

Clunking
If the clunk happens when you drive over bumps, there might be a problem with your car`s suspension, or part of the exhaust could be loose. However, if your car clunks when you`re turning corners, it could be a problem with the steering, wheels and tyres, or a worn-out wheel bearing.
Buildup of Carbon Deposits Commonly, engine knocking occurs because of a buildup of oily carbon deposits inside the combustion chamber. This can be caused by burning oil or incomplete combustion from misfires, which coats pistons, cylinder heads, and other parts of your engine with residue.
