2016 Ford Explorer Loud Noise When Accelerating
A 2016 ford explorer loud noise when accelerating is often caused by an exhaust manifold leak, a failing wheel bearing, or a worn-out CV joint. This guide helps you identify the specific sound—whether it is a ticking, grinding, or roaring—to determine if it is a simple DIY fix or a job for a professional mechanic.
There is nothing quite as unsettling as pressing the gas pedal on your SUV, only to be met with a roar or a rattle that wasn’t there yesterday. If you are currently dealing with a 2016 ford explorer loud noise when accelerating, you know exactly how stressful that can be during your morning commute or a weekend trail run.
You rely on your vehicle to get you safely from point A to point B. When the engine or drivetrain starts acting up, your confidence behind the wheel drops, and your to-do list suddenly gets much longer. We are here to help you cut through the confusion and pinpoint the root cause of that unsettling noise.
In this article, we will break down the most common culprits behind these acceleration-related sounds. From exhaust leaks to drivetrain wear, you will learn exactly what to look for and when it is time to grab your toolkit or head to a repair shop.
Understanding Your 2016 ford explorer loud noise when accelerating
When you hear an unusual sound under load, the first step is to categorize the noise. Is it a high-pitched whine, a deep rumble, or a rhythmic ticking? Each of these distinct sounds points to a specific system within your Ford Explorer.
Most acceleration noises are related to the engine, the exhaust system, or the drivetrain. Because these systems are interconnected, the noise may change intensity based on your speed, the gear you are in, or how hard you are pressing the pedal.
The Exhaust Manifold Tick
If you hear a distinct ticking or tapping sound that gets faster as your RPMs climb, check your exhaust manifold. On the 2016 model, the exhaust manifold studs are prone to snapping or the gasket can fail over time.
When this happens, exhaust gases escape before reaching the catalytic converter, creating that annoying ticking noise. As the engine warms up, the metal expands and the gap often closes, causing the noise to quiet down. If you notice the sound is loudest on cold starts, this is a major clue.
Common Drivetrain and Suspension Culprits
Sometimes the noise is not coming from the engine at all. If the sound is more of a rhythmic growl or a grinding sensation, the issue might be buried in your drivetrain components. These parts take a beating, especially if you enjoy off-roading or drive on rough, uneven pavement.
Wheel Bearings and Hub Assemblies
A failing wheel bearing often sounds like a low-pitched roar that increases with vehicle speed. While it might sound similar to an acceleration noise, you can often test this by gently swaying the vehicle left and right while driving at a safe speed.
If the noise gets louder when you turn, it is a classic sign of a worn wheel bearing. This is a safety-critical item, so if you suspect a bearing is failing, do not put off the repair. You will need a heavy-duty socket set and potentially a hub puller to complete this job.
CV Joint Wear
If you hear a clicking or popping noise specifically when accelerating through a turn, your Constant Velocity (CV) joints are likely the problem. Inspect the rubber boots covering the axle shafts for any tears or leaking grease.
If the boot is torn, dirt and moisture have likely compromised the joint. Replacing the entire axle assembly is generally the most effective way to solve this issue for the long term.
Engine Performance and Air Intake Issues
An engine that is starving for air or dealing with a boost leak can sound surprisingly loud under load. For models equipped with the EcoBoost engine, a whistling or rushing air sound is a common indicator of a vacuum or boost leak.
Turbocharger and Intake Leaks
Check all the rubber hoses connected to your turbocharger and intercooler. Even a small crack or a loose clamp can cause a loud rushing sound when the turbo begins to spool up. This often results in a noticeable loss of power, as the engine cannot reach its target air pressure.
Use a flashlight to inspect the hoses for oil residue, which often highlights where a leak is occurring. Tightening a clamp or replacing a cracked hose is a straightforward DIY task that can restore your engine’s performance.
When to Call a Professional Mechanic
While we encourage DIY maintenance, some noises indicate internal failures that require specialized equipment. If you notice a deep, metallic knocking sound coming from deep within the engine block, stop driving immediately.
This could indicate a rod bearing failure or other internal engine damage. Similarly, if your transmission is slipping or making a grinding noise when shifting gears, you should consult a transmission specialist.
- Safety First: Never work under a vehicle supported only by a jack; always use sturdy jack stands.
- Professional Help: If you lack the specific tools or experience for engine internal work, it is safer to pay for a diagnostic scan.
- Document Everything: Keep a record of when the noise happens and what conditions trigger it to help your mechanic diagnose the issue faster.
Frequently Asked Questions About 2016 ford explorer loud noise when accelerating
Is it safe to drive with an exhaust manifold leak?
While a minor leak is usually not an immediate safety hazard, it can allow exhaust fumes to enter the cabin, which is dangerous. You should have it repaired as soon as possible to prevent carbon monoxide buildup and to restore proper engine backpressure.
Could my tires be causing the loud noise?
Yes, cupped or unevenly worn tires can create a loud, rhythmic roaring sound that mimics drivetrain issues. Check your tire tread for irregular wear patterns and ensure your alignment is correct.
Does the 2016 Ford Explorer have known transmission issues?
While most transmission noises are related to fluid levels or solenoids, the 2016 model is generally reliable. However, if the noise is accompanied by jerky shifting, have the transmission fluid level and condition checked by a professional.
How can I tell if the noise is from the engine or the exhaust?
A simple test is to rev the engine while the vehicle is in Park or Neutral. If you hear the noise, it is likely engine or exhaust-related. If the noise only occurs while the vehicle is moving, it is likely related to the tires, wheel bearings, or drivetrain.
Finding the source of a strange noise can be frustrating, but taking a methodical approach will save you time and money. Start with the easiest checks—like inspecting your tires and exhaust manifold—before moving on to more complex components. Stay patient, keep your workspace clean, and always prioritize your safety. You have got this—get back out there and enjoy the drive!
