When Replacing Wheel Bearings Keep In Mind:
- If the car has a substantial number of miles on the failed bearing , it is a good idea to replace both bearings on the axle at the same time.
- Wheel bearing noise can be confused with tire noise from defective tires. In difficult cases, a mechanic will apply remote wireless microphones at all 4 wheel positions, and then drive the car while listening to a remote receiver, switching between wheel positions to pinpoint the location of the failed bearing.

Will A Bad Wheel Bearing Affect Abs
Wheel bearings are safety-relevant components. They are responsible for stable driving behavior and, depending on the version, provide the wheel speed information for the anti-lock braking system. If the wheel bearing is defective, the anti-lock braking system can also be disabled. In the event of emergency braking, this has a negative effect on the braking distance and the steerability of the vehicle.
How Do Mechanics Replace Wheel Bearings
The complexity of wheel bearing replacement varies greatly depending on the vehicle make, model, year, the wheel position , and the drive type :
- On vehicles with unitized wheel bearing/hub assemblies, the brake rotor and caliper are removed.
- The large axle nut is removed, the axle is pushed back through the center of the unitized hub assembly, and three bolts holding the hub assembly to the steering knuckle are removed.
- The hub assembly is then removed from the knuckle. On installation of the new hub assembly to the knuckle, the bolts are torqued to the factory specification. In many cases, it is required to discard the old axle nut and replace with a new one. Special attention must be given to tightening the axle nut to the exact factory specification because over or under-tightening can damage the newly installed bearing. All YourMechanic professionals use calibrated torque wrenches on these critical fasteners.
- Finally, the brake rotor and brake caliper are re-attached, the wheel installed and the car is road tested.
- On vehicles where the wheel bearing is pressed into a cavity within the steering knuckle, the steering knuckle must be removed from the vehicle in order to press out the old bearing and press in the new bearing.
- On some vehicles, the wheel bearing is pressed onto an axle shaft and thus the axle must be extracted from the axle carrier. This will apply to certain trucks.

DO NOT BUY JEEP!!!!
I have never had to take a vehicle into a dealership as much as this hunk of moving garbage heap. So last time I had my 2014 Jeep Patriot there which by the way only has about 61,000 miles on it, and has never been off road, just a daily driver. This Patriot has a whole host of problems I would not expect from a vehicle unless it had more than 150,000 miles on it. So I described the noises that we were hearing from the front and back of the vehicle and here is the list of problems they discovered with the bucket of rusting bolts otherwise known as a 2014 Jeep Patriot.
* Stuttering problem when going slightly uphill at about 1500 RPMReplace Spark Plugs @159.95 .
* Clunking / Grinding noise from front endNo Grease in Boot / Ripped Replaced under warranty
And finally the item that really has been causing most of the noise was the front wheel bearingsReplacement cost ended being $861.73 Not covered under warranty!!!!I have a Honda Civic which is 6 years older, and has OVER 120,000 miles on it, and is still as quiet as a church mouse.
Oh and they never bothered with the rear noise. Which is why it is back in the shop yet again, and getting the rear wheel bearings replaced as I am writing this complaint.

How Does A Wheel Bearing Work
A wheel bearing is part of the front and rear wheel hubs. In the front, the hub connects the wheel to the suspension’s steering knuckle. The wheel connects to the hub, and the hub spins smoothly inside the wheel bearing. This allows the weight of the vehicle to rest on the hub as it spins while maintaining as little surface contact as possible.
The wheel bearing is lubricated with grease in order to further reduce friction. Most vehicles feature sealed wheel bearings that encapsulate the ball bearings and the lubricant.

How Often Do Wheel Bearings Need Servicing Or Replacement
Most vehicles have sealed bearings that do not require maintenance. Sealed bearings can last 100,000 miles or more, and will need to be replaced once they go bad.
Vehicles with traditional, tapered wheel bearings should have them serviced every 25,000 to 30,000 miles replacement may not be necessary as long as they’re maintained.

Play In Wheel Bearing
You can also recognize a defective wheel bearing if there is too much play. Jack up your Jeep Patriot until the wheel can move freely. Then grab the wheel with both hands at the opposite sides and alternately press and pull. If the play is clearly noticeable and visible, then the wheel bearing is very likely defective. However, this technique requires some experience and a practiced grip.
What Are Wheel Bearings And How Do They Work
A wheel bearing assembly consists of rolling elements, such as hardened steel ball bearings or roller bearings, that roll on and around hardened steel bearing races. The wheel bearings support the front and rear axle, and all the weight of your car. Wheel bearings are made with a high-precision technique using extremely hard steel in order to withstand all the normal impacts that occur to the wheel and tire assembly as you drive along the road.

Grinding Or Humming Noise
Grinding or humming noise in the cabin of Patriot from the direction of the affected wheel is one of the earliest signs of a bad wheel bearing. The faster you drive your vehicle, the louder the humming noise gets. Damage to the wheel bearing is not easy to notice in the preliminary stages, as the noise is barely noticeable. In many cases, however, the noise builds up after a short time often after a few hundred miles.
Jeep Patriot Bad Wheel Bearings Symptoms Causes And Diagnosis
Wheel bearings in Jeep Patriot are one of the most crucial and stressed components. They cause the wheels to turn easily and at the same time absorb high radial and axial forces. Driving your Patriot with a defective wheel bearing can be dangerous, so you must act urgently for your safety and driving comfort.
The most common symptoms of a bad wheel bearing in Jeep Patriot are grinding or humming noise, knocking or clunking noise when cornering, shaking steering wheel, body vibration, uneven or abnormal tire wear, play in wheel, and vehicle pulls to one side when driving in a straight line.

How Long Will The Wheel Bearings Last On My Jeep
In theory, wheel bearings could last as long as your Jeep. Unlike oil changes or tire rotations, theres no standard maintenance schedule for replacing them. However, wheel bearings can be damaged if you hit a pothole, smack into a curb or bounce over a speed bump too fast.
If water, grit, salt or sand get to the bearings, the grease in the hub assembly gets contaminated. This will wear down the bearings, and they will eventually give out.
The best course of action? Find a reputable service technician for advice.
When To Replace Wheel Bearings
-
Growling or grinding noise from a wheel. Failed or failing wheel bearings make a very characteristic growling noise which will grow louder as the bearing wear progresses. If you believe the wheel bearing noise is coming from one side of the car, you can self-diagnosis your wheel bearing as you drive the car by loading and unloading vehicle weight You can do this by swerving from side-to-side. For example, if the noise markedly increases when you swerve to left, which shifts the vehicles weight to the right, then it often indicates the wheel bearing on the right is failing.
-
Axial or radial play in the wheel or wheel hub. Should the wheel hub move up and down or in and out, the bearing may be worn.
-
Vibration in the steering wheel or vehicle body and/or wandering. Vibration and lack of directional stability could be consequences of loose or worn out wheel bearings.
-
Tire and wheel assembly does not turn smoothly. With the wheel jacked up, and the car not in gear, the wheel should rotate smoothly. Rough or inconsistent movement, which is often accompanied by noise, can signify damaged bearings. Be sure the brakes are not dragging as you perform this check.

Check For Wheel Bearing Seal Leakage
Many wheel bearings are permanently sealed. But if the seal deteriorates, the grease will leak out. So check for signs of grease leaking from the bearing. A wheel bearing with seals should never show signs of leakage. If it does, its bad. Any seal thats leaking grease is a seal thats also allowing water to enter the bearing.
How Long Do The Wheel Bearings Last In Jeep Patriot
Under normal driving conditions, wheel bearings typically last around 100,000 miles. The mileage depends on the driving style and the quality of the wheel bearing. If you frequently drive your Patriot on bad roads with lots of potholes, drive over curbs with force or drive quickly around corners, the service life of the wheel bearings is significantly reduced.

How Long Does It Take To Change A Wheel Bearing
Replacing a single wheel bearing of Patriot typically takes 1 to 2 hours for an experienced mechanic. Sometimes it can take longer if the wheel hub is stuck, it then requires a lot of hammering or use of different tools and techniques to remove the hub. There are also a lot of moving parts that need to be removed and then properly reinstalled to complete the task. Due to the complexity and sheer manual labor, it is not recommended as a DIY project.
Is It Safe To Drive With A Bad Wheel Bearing
The short answer is: Not for too long. Having bad wheel bearings can range from inconvenient and unpleasant to downright dangerous.
If you have bad wheel bearings, you might experience the vehicle pulling to one side, sloppy or loose steering, grinding and rattling noises, and uneven tire wear.
In the worst case scenario, the wheel could come off while you drive.

How To Replace A Worn Wheel Bearing
If the hub bearing is a unit bearing assembly, you must replace the entire unit. Remove the axle nut , and then remove the hub retaining bolts. You
Wheel bearing hub assembly
may have to pry the old unit out from the knuckle.
If the wheel bearing is pressed into the knuckle, you must rent the proper tools to remove it or remove the entire knuckle and take it to a machine shop and pay them to swap out the bearings.
Tightening The Axle Nut
Always replace the axle nut with a new part. The single biggest mistake you can make when reassembling the new bearing is to use an impact wrench to tighten the axle nut. The rapid impacts can chip the chrome plating off the roller or ball bearings and can damage the internal races. You wont notice the damage right away, but the bearing will fail early due to damage you caused with your impact wrench.
So tighten the axle nut by hand using a ratchet and socket to seat the nut. Then use a torque wrench to set the pre-load according to spec. Failure to use a torque wrench can cause premature bearing failure!! Proper preload is critical! If the preload is less than spec, the bearing can separate.

There is a common problem with Jeep Compass/patriot vehicles where the rear wheel bearings begin to hum and grind at low mileage. I believe this is a known issue as Mopar appears to have superseded the part number a few times. My wife�s patriot developed said bearing issue on driver side at only 60k miles. Upon researching, I�ve seen tons of reviews saying the Timkens hold up better so went ahead and bought two of these to do both sides. They went on painlessly and resolved the loud bearing noise we were hearing. Parts geek price was among the best and shipping was very quick thanks guys! – Quality replacement hubs

Can I Drive With A Bad Wheel Bearing
Yes, but not for long. As the wear increases, so do the chances of damage occurring to other parts of the suspension.
If you suspect that a wheel bearing is beginning to wear, have a technician evaluate the problem as soon as possible. A vehicle with a significantly worn wheel bearing shouldn’t be driven. If the wheel bearing fails completely, it’s possible for the wheel to come off the vehicle and cause a wreck.

Premature Wheel Bearing Failure Due To Contamination
When the wheel bearing rotates, there is high friction. Therefore, the internal components must be lubricated with lubricants such as grease or oil to prevent overheating. The wheel bearings in Jeep Patriot are designed in such a way that they are absolutely maintenance-free. This is achieved with a grease filling that ensures adequate lubrication of the rolling elements over the entire service life of the wheel bearing.
Elaborately designed seals ensure that neither water nor dirt can enter the wheel bearing. But if the seals fail, water and dirt can enter inside the wheel bearing and contaminate the lubricant. These contaminants circulate throughout the grease and between the races and the bearings accelerating the wear rate. The increased heat may break down and eventually expel the lubricant, leading to premature failure of the bearing.
Knocking Or Clunking Noise When Cornering
At an advanced stage of internal deterioration, the defective wheel bearing can cause knocking or clunking noises, particularly when turning or cornering in your Jeep Patriot. However these noises can also occur due to faults in suspension or steering system components, therefore you should consider a bad wheel bearing if the vehicle presents other system as well, like humming or grinding noise and play in the wheel.

Should I Replace Only The Defective Wheel Bearing In Patriot
In general, it is advisable to change the second bearing on the same axle even if there is only one defective wheel bearing in your Jeep Patriot. It can be assumed that both bearings were subjected to roughly the same stress and that the failure of the second bearing is imminent. If they are replaced at the same time, this saves time and money.
Check The Wheel Bearing For Play
Grab the tire at the 2:00 and 6:00 oclock position and pull and push to detect hub movement. Dont confuse rubber movement with hub movement.
Check wheel bearing by placing hands at 12:00 and 6:00 and rocking wheel in and out
Then move your hands to the 3:00 and 6:00 oclock positions and repeat.
Then try rocking at 3:00 and 9:00

What Causes Bearings To Fail In Jeep Patriot
Even when driving your Patriot in a straight line, the bearings have to absorb high radial forces. The entire weight of the vehicle rests on the bearings. When driving, the speed creates additional forces. If a curve is then also driven through, axial forces occur. High impacts on the bearings also occur on uneven roads or when driving through potholes. Impacts of all kinds are much more damaging to bearings than the high loads. Therefore, all wheel bearings eventually fail. However, how soon they fail depends on driving habits. Other factors can also contribute to premature bearing failure on your Patriot, like driving with unbalanced tires or poor wheel alignment.
I Hear A Grinding Noise Coming From My Jeep
If you hear noises at the wheels, one explanation might be a need for a wheel bearing replacement at one or more wheels. The noises might be described as rattling, clicking, humming, growling, or squealing. It can be a real symphony of sound if youre not careful.
More than just noisy or bothersome, bad wheel bearings could also lead to real performance issues like inconsistent braking, spongy steering and handling, uneven tire wear and, in extreme cases, the wheels could fall off. No matter how much you know about cars, you dont want the wheels falling off, right?
Dont ignore the issue. Best to get it checked out by a trained service center.
