Jeep Grand Cherokee Humming on Acceleration
Faulty wheel bearing
Humming noises in your Jeep Grand Cherokee can be caused by a faulty wheel bearing. A grinding or humming noise coming from the direction of the affected wheel is the most common sign of poor wheel bearing.
Humming noise is the first sign of faulty bearing. After confirming that your Jeep has a bearing problem, you must replace the wheel bearing.
You’ll need to use a jack to lift your Jeep so you can replace the bearing. Remove the wheel after that. Using impact tools, remove the CBC wheel. Remove the brake caliper from the rotor and pull the rotor away from the jeep. Replace the worn-out bearing with a new one.
Even if your Jeep Grand Cherokee only has one defective wheel bearing, it’s a good idea to replace the second bearing on the same axle. It’s safe to assume that both bearings were under similar stress and that the second bearing will fail soon. It saves time and money if they are both replaced at the same time.
Uneven tire wear
Humming noises in Jeep Grand Cherokee can also be caused by unevenly worn tire tread.
Vehicle owners should consult their owner’s manual and adjust their tire pressure according to the manufacturer’s recommendations to fix this type of wear.
Low transmission fluid
Low transmission fluid issues are easy to check and fix. You can able to check the position of the transmission fluid by checking the transmission pipe under the hood.
Pull out the transmission dipstick to check the fluid levels. The location of the dipsticks is described in detail in your owner’s manual. If your fluid level is low, you’ll need to top it up.
Faulty transmission gears
When you accelerate, if the gears in your transmission system are worn out, you’ll hear a humming noise. In this case, you should take your Jeep to a dealership or a local mechanic.
If your tires are severely worn, you may hear a humming noise when accelerating. Tires that have been worn down will not perform well in snow or during rain. Which raises the risk of an accident. So replace it with a new tire in this case.
Loose steering belt
When the steering belt on your Jeep becomes loose, it may make a humming noise when you accelerate. If this is the case, you have to tighten the steering belt. Put the wheel straight. Go underneath the jeep to fix it up. Adjust the steering belt with a wrench.
Exhaust system leaks
If none of the other common causes of humming in your Jeep Grand Cherokee have been addressed, exhaust system leaks may be the cause. It will be difficult to tell whether or not your exhaust system is leaking. If you suspect this is the problem, you should consult an automotive professional.
