Whirring Noise: One of the pronounced bad pinion-bearing symptoms is its whirring noise during acceleration or deceleration at various speeds. Worn out pinion bearings create more whirring noise rather than rumbling because it rotates several times faster than the carrier assembly of the vehicle. Vibrations: Vibration is one of the pronounced signs you can easily notice. Worn-out pinion bearing results in noticeable vibration or differential noise on acceleration.
Gear grinding: Gear grinding or humming noise is another symptom that reveals a bad pinion bearing. The gear grinding is produced in the process of acceleration of the vehicle. Tire damage: Tire damage is also one of the bad front pinion-bearing symptoms. Due to the higher speed of the inner tires, which is more than what the inner thread can sustain, the vehicle tires tend to wear out or get damaged in taking corners with the wheels and tires traveling at the same speed.
Failure from Lubrication: About 80 percent of pinion bearing failure is traceable to inadequate lubrication. Sometimes, it could be insufficient lubrication, inappropriate lubricants, or degradation of lubricants due to excessive temperature. Corrosion: Corrosion is another cause of pinion-bearing failure.
Corrosion could result from acid, moisture, broken down or low-quality grease, etc. Misalignment: Misalignment can result from bent shafts, out-of-square clamping nuts, out-of-space shaft shoulders, out-of-square spacers, and improper installations.
This error can lead to overheating and separator failure. Improper Mounting: Pinion bearings should be mounted with a press on the floating ring. Mounting bearings on shafts by applying blows or pressure on the outer race, poor finish on the bearing seat, etc.
False Brinelling: False brinelling results from lack of rotation in the bearing, which disables fresh lubricants from returning to the spot, and a rapid movement of the balls while the vehicle is idle. Fatigue: Overloading, excessive preload, the tight inner ring fits, and excessive bearing above lifespan can result in fatigue, which later results in pinion bearing failure. Overheating: Improper lubrication and excessive temperature can cause overheating. High temperature can cause loss of lubricating oils from grease, resulting in dryness that causes the bearing to seize.
Excessive Loads: Exerting too many loads than necessary on a bearing can also cause pinion bearing failure. Understanding the causes of pinion bearing failures and the symptoms of bad pinion bearings is a significant advantage for ensuring long-life pinion bearings. It is better to take preventive measures to ensure that your pinion bearing lasts longer. Proper lubrication: It is essential to use the appropriate or recommended lubricant for pinion bearing to ensure its longevity.
Avoid loss of grease and pay necessary attention to recommended intervals for an oil change. Careful mounting: Endeavor to follow proper mounting instructions provided by your vehicle manufacturer or vehicle experts when mounting bearings.
Keep corrosive fluid away: Ensure to keep corrosive fluids such as acid, water, etc. Reduce loads: Ascertain the maximum amount of load the pinion bearing can carry and stick to it, or use a bearing with greater capacity for loads.
Carefully store bearing before use: Make sure you store bearings in a dry environment at room temperature. Please visit our Returns page to download a returns form and for further information. Shipping Countries - Click here for more information.

Step 2: Raise the axle. Step 3: Set the jack stands. Step 1: Set the parking brake. Step 2: Secure the driveline. Step 3: Remove the driveline mounting bolts. Step 4: Separate the driveline. The first and most common is loss of differential oil which can cause gears inside the differential housing to break, grind, or even block the rear wheels.
Also, it is known that differentials can break if the inside gears are made of softer-type steel which is not able to withstand engine power and torque. The pinion seal is located inside differentials of vehicles.
The pinion seal is located near the pinion shaft and is designed so that fluid does not leak out of the differential. Estimate does not include taxes and fees. The heat would crash the wheel completely. To avoid this situation, it is recommended to drive at the slower speed so that your wheel stays in action a few more hours. SO, while thinking how long can you drive on a bad bearing? You should not go more than miles as it might result in some bigger issue.
It may become more pronounced during turns as the car's weight shifts and a different load is placed on the wheel. Ultimate damage: If you don't replace a damaged wheel bearing before it fails completely, the wheel will completely seize up.
If this happens while you're driving , the results can be catastrophic. How do I know if I have a bad pinion bearing? Category: automotive auto parts. Overly worn out bearings tend to make a howling noise when they do not properly support the gears. Rumbling while turning, on the other hand, is a sign of bad wheel bearings.
