Jeep Wrangler Vibration When Accelerating

It is common for Jeep Wrangler Vibration When Accelerating or slowed down. However common it may be, this isn’t normal. It can be quite disappointing and often infuriating to watch your vehicle turn into a shaker whenever you are about to reach your destination. We obviously expect better out of these beasts we invest our hearts in. 

We have conducted a detailed analysis to figure out why your Jeep Wrangler undergoes vibration when accelerating. We’ll help you ascertain the cause behind the embarrassing vibrations in your own Jeep Wrangler. Also, we’ll help you mitigate any damages that may ensue from this problem. 

It is important to note when your vehicle vibrates 

If your car vibrates when it is accelerating or slowing down, it is essential for you to get to the root of the issue. It is typical of Jeep Wranglers to undergo vibration when you push their gas pedal or when you press the brakes. However, if you are not sure what exactly gives rise to this problem, consider whether the vibration starts at the time you are approaching a stop sign. 

Your vehicle probably accelerates every time you are accelerating before turning around a corner. Even during emergency stops in traffic, it is possible that your Jeep shakes up with a jerk. And maybe you start vibrating embarrassingly when you attempt to cross another vehicle.

All the above instances should be sufficient to direct you to a good mechanic. Whatever be the reason behind these vibrations, it should be solved immediately to prevent serious damage. If a problem in your car is left unattended and ignored, it is bound to only grow further, not slow down. You could be surprised with a grave concern in the future. 

To avoid getting stranded on a road someday, visit a quality mechanic as soon as possible.

Jeep Wrangler Vibration When Accelerating

There could be several reasons behind your vibrating Wrangler

The vibrations and stutters shown by your Jeep Wrangler would surely be disappointing. While there may be many causes that could only be examined by a proper technician, there are some common reasons that exist more often. One of those reasons could be your drastically imbalanced wheels. Other than that, the U-joints in your Jeep could be worn out. More often than not, the problem could lie in your Jeep’s tires.

Vibration upon acceleration is commonly caused by imbalanced wheels 

Even your newly purchased high-quality wheels could cause vibration problems in your Jeep Wrangler. Because if your wheels are imbalanced, it doesn’t matter how efficient they are otherwise. Most vibrational problems in Jeep Wranglers are often caused by this easily preventable reason. An imbalance in the wheels would lead to stronger vibrations when you increase your speed. 

Worn out U-joints could also cause vibrations 

A deeper examination could reveal a problem in the U-joints. These joints are the facilitators that let the suspension system move upward and downward while you’re steering your Wrangler. Jeep Wrangler is a rear-wheel drive vehicle and U-joints are an excessively mobile part. The excessive mobility leads to more wear and tear. It is only natural for these joints to demand replacement after some time. 

One must note that different Jeep Wrangler models will have different U-joints. These joints are sealed in some models while they are incorporated with a grease fitting in others. The fitted U-joints need to be greased regularly. Severe usage could cause their failure over time so that they’ll need replacement.

When the U-joints are worn out, vibrations occur at every speed the vehicle is driven at. When you put the transmission into gear or when you suddenly change speeds, a worn out U-joint will typically emit a clicking sound. 

Worn out tires are amongst the common culprits behind vibrations

Oftentimes, the problem lies in the worn out tires. If the hefty tires of your Wrangler have worn out unevenly or have become separated, there could be severe vibrational disturbances every time your Jeep is sped. It is also possible for your tires to be inflated and improper pressures. A proper maintenance plan will save you from these unsettling vibrations and make your car last longer. 

While the imbalanced wheels, worn out U-joints, and the improper tires could possibly be the reason behind your shaky Wrangler, they are surely not the only culprits. It is possible that your Jeep has problems in its transmission system. Or maybe your driveshaft needs repair. One less common instance is when your brake pads or rotors are worn out. 

There could be a problem with your driveshaft

If the wheels of your vehicle are perfectly balanced and the tires are not worn out, your diagnostic process is bound to extend deeper. There could be an imbalance in the driveshaft. A problematic driveshaft is more likely to cause trouble in a rear-wheel drive than a normal FWD vehicle. 

The runout for RWD drive shafts is as much as 0.010 inches. This is about half of the acceptable runout measurement in FWD. Many FWD drive shafts have a vibration damper in place to effectively control these torsional vibrations. Note that most FWD drive shafts are imbalanced at the factory because these are meant to turn at the same speed as the wheels. 

The protective weight may have been lost or removed and could be the reason behind these vibrations. It is also possible that your vehicle has an excessive driveshaft angle. If you have raised or lowered the normal height of your Wrangler by some degree, this problem will be more commonly encountered. 

If a U-joint is disturbed by more than a few degrees, cyclic vibrations are induced in the shaft. A greater disturbance in the angle will only increase the strength of these vibrations. This problem is less apparent in FWD cars as their worn CV joints click rather than vibrating. 

Remember to examine the wheel bearings in your vehicle. Bad quality wheel bearings could cause chirping, grumbling, or squeaking noises.

Consider the resonance vibration in the exhaust system

Resonant vibration in the exhaust system of your vehicle can be easily confused with vibration in the wheels. Natural vibrations occur in the exhaust system of your Jeep Wrangler. At certain high speeds, these vibrations may stack up and cause the exhaust to start resonating. 

This problem could emanate because of a recent change in the exhaust system or a bent pipe. It is also possible that your original ‘tuning’ weights may have been removed or have gone missing. This could be a possible reason behind the vibration of your Jeep at unexpected speeds. 

Check your control arm bushings, shocks, and ball joints

If your Wrangler started showing the vibrational symptoms after once hitting a bump or a rough road, it is possible that your shocks are worn out. A bad quality hydraulic stabilizer system may also express its damage in a similar manner.

If your Jeep makes a whining noise that gets louder as you decelerate, it is possible that your bearings and gears have worn out. A severe problem in the differential gears would typically emit such noise. If you happen to hear problematic gear noise, first check the levels of lube in the differential portion, transmission, and the transaxle. 

One lesser examined source of vibrations could be the lockup torque converter. This portion could cause a shudder during its engagement and disengagement. A bad quality vehicle speed sensor or engine computer would contribute more to this problem. 

Consider the other simpler sources of the problem

While it is possible that your shock absorbers may have become faulty, or your spring mounts and ball joints have worn out, and even your exhaust system could be improperly hung. Sometimes, the problem may be simpler than we think. 

It is also possible that your steering wheel is loose and needs maintenance. Your steering rack mounts or the tie rod ends could have worn out. Maybe one of your doors does not close properly, or your windshield is improperly fit after a previous impact. 

It is suggested that you take your Jeep to a mechanic and have it examined properly in running condition as well as on a lift. 

Conclusion – Jeep Wrangler Vibration When Accelerating

There could be many reasons behind the embarrassing vibrations of your Jeep Wrangler. We have mentioned the most commonly encountered reasons above. The actual reason behind your Jeep Wrnagler’s vibrations can only be explained by a qualified mechanic. 

It is not wise to wait for such symptoms to get worse. As soon as you first notice a problem, take your Jeep to a qualified mechanic and get a viable solution. It will typically involve the replacement of some worn out or problematic parts. Note that the issues and the expenses of repair will keep elevating if you wait for things to get better on their own.
