You should first look for an oil leak if you’ve noticed a humming noise when accelerating. If that doesn’t fix the problem, you can try checking the steering wheel and exhaust manifold bolts. If none of these work, you need to replace the exhaust manifold. You can usually find a replacement for the part for cheap. If the noise continues, you should visit a mechanic to find out what the cause is.
Causes of a Humming Noise
If you notice that your Jeep is making a humming noise when you accelerate, you may have several possible causes. Tires are one potential cause of this issue, as they may not be properly aligned. Depending on the severity of the noise, it could be a simple fix, or it could mean that a complete replacement is needed. There are several things to look for, so make sure you thoroughly inspect before making any repairs.
One of the most common causes of a Jeep Grand Cherokee humming sound accelerating is the serpentine belt. This belt takes motion from the crankshaft and turns accessories. Consequently, if the belt is broken, the noise will be high-pitched. This problem is more detailed in our article on the whining noise while starting your car. To diagnose this issue, you must repeatedly start your Jeep.
A faulty brake assembly or push rod is another possible cause of a Jeep humming noise while accelerating. If this is the case, you should have the front end checked. In addition to this, the brake shields and the axles may be at fault. Regardless of the cause, it can result in a dangerous driving condition and an expensive repair bill.
The power steering pump is another common cause of a Jeep Grand Cherokee humming sound when accelerating. The power steering pump may be running low on fluid or even out. To test whether this is the cause, try turning the steering wheel while the Jeep is sitting. Its whine will change with the RPM and steering wheel movement, so check that your power steering pump is running at a whole level.
Checking For An Oil Leak
If you’re getting milkshake-colored oil while accelerating, you may be experiencing a leak in your Jeep’s transmission. Check the oil level in the engine and check for white smoke coming from the tailpipe. High oil pressure can also cause an oil leak. Lastly, a burning smell may be coming from the transmission. All of these symptoms may indicate a faulty transmission.
First, you should check the engine’s oil filter. If there’s any oil under the Jeep Grand Cherokee’s hood, it’s likely the oil filter. You should also check the power steering fluid. It’s possible to detect transmission fluid leaks by looking for a low-level and foamy fluid.
Another problem with the ignition system on your Cherokee is the spark plugs. When these fail, your Jeep will lose performance and power. Additionally, you’ll notice blue smoke coming out of the tailpipe. A bad spark plug can also lead to engine cutouts and other costly consequences. When your Jeep Grand Cherokee starts jerking while accelerating, the spark plugs may be causing the problem.
The next problem you’re likely to encounter when accelerating in your Jeep Grand Cherokee is a smell. It is likely coming from the engine. The engine is probably leaking oil from the valve covers. Checking for an oil leak is an essential part of any maintenance routine.
Another possible cause of poor acceleration in a Jeep Grand Cherokee is a dirty or defective mass air flow sensor (MAF). This is a relatively easy fix. The next step is to replace the MAF sensor. The mass air flow sensor will tell you whether you need to replace the engine. The sensor’s malfunction may be easily detected with a diagnostic device. Luckily, the diagnostic device is relatively reliable.

Checking For Loose Steering Wheel
You’ve probably hit a snag if your steering wheel feels loose when accelerating in your Jeep Grand Cherokee. You might feel the steering wheel “return” too quickly or feel the vehicle pull to one side. The cause of this issue can be a loose steering wheel or a faulty tie-rod. To identify the cause, try turning the steering wheel while stationary. There’s a problem if the wheel turns less than 7cm at the wheel rim. Typically, your mechanic will raise your car and check the steering linkage and box for signs of wear and leaks.
Another reason your steering wheel shakes when accelerating is tire damage. Visually inspect your tires, as damage can be hidden, especially on newer tires. Other common causes include bent rims or damaged tires. In some cases, bent rims may cause steering wheel shakes. If your rims are bent, driving over obstacles too quickly can cause them to bend. While balancing your wheels will not cure this issue, replacing the rims will help you find the culprit.
If your Jeep Grand Cherokee shakes while accelerating, it may signify a worn component. Your Jeep Grand Cherokee might be lacking an axle, which is the rod or shaft that rotates the wheels and transmits power from the engine to the wheels. If you experience these symptoms, get your Jeep Grand Cherokee to a mechanic for a thorough inspection. In some cases, loose wheel bearings can cause the steering wheel to vibrate and cause other problems.
The loose steering wheel can signify a loose tie rod or lousy tie rod ends. If these are the culprit, it’s time to replace them immediately. A loose steering wheel can cause an accident. So, check for this issue immediately. You’ll feel a significant difference when you drive your Jeep Grand Cherokee.
Broken Exhaust Manifold Bolt
A cracked or broken exhaust manifold can result in various symptoms, including a loss of power and fuel consumption. Even though it’s relatively simple to replace, you should know how to tell if your exhaust manifold is the culprit. Here are some signs to look for:
The most common cause is a damaged bolt. A broken bolt can lead to various problems, ranging from poor performance to a ruined exhaust system. To avoid such problems, you should try to check for a broken bolt before calling a mechanic. Try WD-40 or use vise-grips to tighten it if you can’t find one.
A cracked exhaust manifold can also cause a loss of power while accelerating. This is one of the most common exhaust issues, and you should have your car checked by a mechanic as soon as possible. A cracked exhaust manifold may indicate that a gasket is leaking or cracked. Either of these issues can lead to a hazardous situation.
A leaking exhaust can be an extremely loud warning sign of trouble. The exhaust leak can cause damage to the engine and poses a health risk. The exhaust manifold gasket is responsible for sealing the exhaust manifold between the engine cylinders and the exhaust system. These gaskets are made from embossed steel, graphite, or these materials.
If you hear a loud rumble when accelerating, your exhaust manifold is damaged. In addition to leaking exhaust, a cracked or damaged exhaust manifold won’t transfer heat as it should, which can damage the gasket. Even worse, it could cause exhaust leaks or damage to the gasket. If this is the case, it’s best to replace it now.
