What happens whena wheel bearingfails

Infortunately my mechanic isn’t too comfortable talking about his procedures, i.e. being questioned. In the past, he’s said that this just happens wtih some cars and then he hands me the bill. About $175 labor + $50-60 per axle.

Your experience is unusual. Something about that car is not right. Do the bearings look like they have been unusually hot, such that the grease was destroyed?

These days, when you hear about someone replacing any wheel bearing, the car probably has 200k or better on it. I replaced all four wheel bearings on my '91 Volvo by the time it hit 250k miles.

Back in the day, with RWD cars, the front bearings were open tapered roller type, you could remove them, clean them and re-pack them. This was part of a front brake job…Kept clean and lubricated, they would last the life of the car…Todays cars use sealed straight rollers that perhaps have a little more trouble absorbing side loads than the old tapered roller design…And they can’t be cleaned and re-packed…As with ANY bearing, once the seal fails, the bearing is not far behind…

Although high quality ball bearings are generally durable components – especially when purchased through a reputable supplier and produced by a world leading brand, such as Dunlop – these components can and do develop faults through regular use. Recognising the first signs or symptoms of ‘bad’ ball bearings will enable rapid repair or replacement before excess friction and waste heat leads to mechanical damage or premature failure in your application.

-----You don;t say how many miles you have on the car, but wheel bearings going bad within two years of driving suggests either an installation problem or poor bearings. Without seeing how they were installed (did the guy on the press force them in by using the inner race?) it’s impossible to guess.

Even a small lubricant leak is a red flag of a potential problem, often the result of a damaged seal on a bearing allowing lubricating oil to leak out from inside the component itself. The immediate result is less protection for the bearing and an increased risk of further wear and tear over time. A lubricant leak could progress into additional symptoms, such as excessive heat, vibration, and noise, and the issue should be addressed as quickly as possible.

Heat during operation is generated through a build up of friction – an issue that ball bearings are specifically designed to avoid. Above usual levels of heat are, therefore, a common sign of friction building up between the bearing surfaces and should be addressed quickly before it causes overheating and damage. Excess heat can have a detrimental effect on other components in your system if it is not addressed promptly.

Bad wheel bearingsound

The roads aren’t too bad. I live in the city of Chicago. Some roads are a little rough though overall they’re fine. I don’t know about the warranty on the wheel bearings. I’ll check with the mechanic. My guess is they don’t have a long warranty given that the mechanic I used did the bearings twice.

Bearing failure IMO, is dependent more on vehicle use with th influence of poor design. I wonder how well the bearings are sealed ? Check with the dealer on recalls.

The mechanic has shown me the bearings. It looks like the grease is almost gone and you can see rust starting to develop. Does this mean they’re running too hot? Or could there be an issue with sealing?

Wheel bearingfailure symptoms

I’ve had a couple of wheel bearings go bad over the years. Yet, given the number of cars I’ve had and all the miles driven bad wheel bearings is a rare event. Your experience is either a bad design or someone is using cheap parts.

Dec 4, 2012 — my bearing seized up and I want to know how to unseize it.

About 85K. not sure about the installation process, that is did he force them using the inner race. I’m pretty sure it’s the front . Since it’s happen quite often with this car, I’ve gotten accustomed to the presence / location of the sound.

One of the tell-tale symptoms of a failing bearing is excessive or unusual noise during operation. In particular, a growling, squealing, or humming noise could indicate insufficient lubrication, poor alignment, or the early stages of a mechanical fault.

In the interest of full disclosure, I did have about 180,000+ miles on the originals. I guess I can’t complain too loudly.

Of the 8 cars I’ve owned over the years, I’ve only had to replace 3 front wheel bearings. If driven on smooth roads, bearings can last the life of the car. It’s something yoiu just don’t worry about anymore. Owner’s manuals seldom mention bearing service anymore.

A good ball bearing will be designed to minimise vibrations during operation, with a smooth transfer of motion and kinetic energy. Vibrations, therefore, can be a sign of a problem with your bearings. For example, if the ball bearing is not properly aligned or is damaged or worn, it will start to vibrate unusually during operation, even at its specified speed and load.

How to tell whichwheel bearingisbadwhile driving

Back when I was a kid in the 50’s, a car lasted about 100k miles, and it was not unusual to have to replace at least the front wheel bearings once in the life of the car.

I had to replace a left front wheel bearing on a 2006 Chevrolet Uplander at about 65,000 miles and a left front wheel bearing on a 2003 Toyota 4Runner at 72,000 miles. In all my previous vehicles, I never had to replace a wheel bearing. I do remember repacking the front wheel bearings on my rear wheel drive cars that were made back in the 1940s through the 1970s. The rear axle wheel bearings were lubricated by the 90 weight oil in the differential and rear axle. My only explanation for having to replace the wheel bearings in my more modern cars is that sometimes parts just wear out prematurely.

In this article, we discuss the main early warning signs to look out for that could indicate an emerging fault with your bearings.

Today’s cars use double row “tapered ball bearings”, which are just ball bearings in tapered casings. They do it to reduce rolling resistance. Here’s an example. http://tijil.org/Scion_Docs/Scion_06_misc_docs/2007sciontc_ncf%20Folder/axle.pdf

I’ve got a Mazda Protege5. I had the wheel bearings replaced right of the box shortly after I bought the car new in 2004. They went bad again in July 2011 and now they seem to be going bad again. That same familiar sound. Seems strange to me. I’m not hearing anyone else talk about regularly having their wheel bearings go bad.

Spherical ball bearings are intended to rotate in all directions, accommodating both radial and axial loads. Rough or sluggish rotational movement may be the sign of wear and tear or physical damage, so if you notice a change in the range of movement when using your machinery, we recommend inspecting each component carefully to identify any potential issues.

I had to replace a left front wheel bearing on a 2004 PT Cruiser at only 40,000 miles. By browsing PT forums I found out that in high salt areas they were discharging static or other elecrtricty to ground through the left front tire and it was causing arcing inside the bearing.

I just recently replaced my front bearings. I was downright miffed when I discovered that they were using ball bearings for reduced rolling resistance. Darned CAFE requirements.

I actually misspoke in my initial post. The dealer replaced the bearings right out of the box. These lasted from 2004-2009. The same mechanic replaced the bearings in 8/09, 7/11, and now they’re going bad again. I hear the same familiar sound.
