To replace a wheel bearing properly, it has to be popped out of the hub assembly, preferably using a hydraulic press. Problems can arise with the re-installation of the new bearing, as the alignment must be accurate to avoid the bearing wearing out rapidly and causing further pain.

Wheel bearings play an important role within the drivetrain of any vehicle, as they provide the first connection between the moving and static areas of the car. A bearing – in its simplest form – is a friction reduction device placed within something like a wheel to aid the efficiency of rotation. This is achieved as rolling produces much less friction force than sliding.

Last year I was driving from Townsville to Brisbane. And about 800km in the wheel bearing on the rear right wheel went which shook the wheel completely off. I was only a learner at the time so it was the scariest thing that had happened to me while driving. The worst part was the car had just been serviced for the trip and the bearings had been replaced.

With roller bearings , coat the outer race thickly with grease. Spin the rollers in their cage on the inner race while rubbing grease into every crevice.

The most common mechanical failure is due to a seal leak, which allows the lubricating grease to exit the bearing, and water and grit managing to worm its way in. This all amounts to the degradation of the balls and the outer and inner housing of the bearing, often creating that gritty, skimming sound as the wheel is rotating. Looking inside a worn-out bearing, there will often be small specs of metal that have broken off from inside the bearing itself and are grinding their way around the racers, causing more damage. If you have had a minor shunt, it’s always worth having the hub assembly checked over afterwards.

Wheel bearings should last tens of thousands of miles, but many mechanics will simply hammer the bearing back into the hub assembly instead of precisely aligning it and using the aforementioned press. This will inevitably lead to the bearing not rotating in the perpendicular fashion that it was designed for, accelerating wear and damage to the part. It’s important, therefore, if you’re not 100 per cent confident in your own ability, to ensure you’re using a trusted, professional garage.

For the inner races and the rollers or balls make no allowances at all. Any blemish is unacceptable and means renewal of the bearing.

Hey, i have driven a car to the limit where humming sound is so loud inside that you can’t even hear a Radio. They can last a long time before they go, even if they are shot.Also had an situation where from the moment bearing started to hum, till it disintegrated it self, it lasted about 2 km…. I guess it depends on how good brand you use and how lucky you are.

The wheel bearing is housed within the hub assembly, providing the static connection with the hub carrier through an outer ring or ‘racer’. On driven wheels, the driveshaft travels from the transmission and passes through the centre of the wheel bearing through the inner ring, creating the rotational partnership. Ball-type bearings are generally used on the driven wheels of a vehicle, while tapered roller bearings, with cylindrical rollers arranged around an inner ring, are predominantly used on the non-driven wheels.

Clean the hub and races well with paraffin or white spirit. Then drive the races away from each other. The inner and outer races may be of different sizes. If so, begin with the smaller one.

Wheel bearings are generally made from hardened steel, so they can withstand a serious amount of rotational abuse. But apply heat (through lack of lubrication) or dirt and water (broken seal) and all hell can break loose (this is yet another reason to avoid driving through deep water). Hitting one too many potholes or taking speed bumps too quickly can also exert excessive force on your bearings, shortening their useful life.

There’s a decent chance that at some point, you’ve had your car back from an MOT test and found a patch of orange on the results that says something along the lines of ‘play in offside front wheel bearing.’ It sounds scary - after all, in order of everything you want to function correctly on your car, the wheels are pretty far up the list.

Although it can be a labour-intensive job if one were to fail, the shift to selling entire hub assemblies should make a bad wheel bearing fixable from home, with a decent tool kit and a bit of know-how. So do not fret the next time that horrid whir begins to creep into the cabin, as a fix may be only a ratchet spanner away.

Lengthen the socket with an extension piece and tap this gently with a heavy hammer to expel the race. Use a bigger socket to force the other race out in the opposite direction.

As long as you catch a wheel bearing issue early, though, it shouldn’t be a massively expensive or time-consuming fix, and if you’re decent with a spanner, it’s potentially something you can sort yourself. Here’s what a wheel bearing is, why it’s important, and how to tell if there’s something wrong with one.

Carefully push the hub on to the axle, taking care not to knock out the inner race of an outer ball bearing with the axle end.

I feel dumb because I cant figure out how the bearings work with the rotating axle and how it doesnt just spin and the wheel not move.

Put the inboard inner race into its outer race; or tap it on the stub axle with a tubular drift if this is more convenient. Do not forget to fit any spacer between the bearings.

With either type of bearing, now insert the new grease seal . Be sure to fit it the right way round. If it fits flush with the inner edge of the hub, tap it gently home with a wooden block. If it is recessed, use a socket to press it in.

Insert a new split-pin, head uppermost, and open the legs. Trim the legs so that they will not prevent the dust cover being fitted. Reassemble the brakes.

Most online parts stores will now sell the entire hub assembly with the wheel bearing pressed into it, saving the hassle and potential scope for mistakes within the specific bearing assembly. It goes without saying, but you should also make sure that, if possible, you or the garage is using an original manufacturer part or one of reasonably similar quality - this is one area you really don’t want to skimp on.

Pack the bearings with an approved type of bearing grease - consult the car handbook or a dealer if in doubt. Find out also how much grease to apply. On some hubs the central area is heavily loaded with grease, but other types need only a light coating. Always fill the bearings themselves with as much grease as they can hold, forced in between the races.

A car’s wheel bearing does this by using small metal balls or cylindrical rollers that roll between two smooth rings of metal. Helped along by grease, the bearing rotates in tandem with the wheel’s rotation, the rolling motion of the balls or rollers allowing the wheel hub to rotate as freely as possible. It also helps absorb some of the forces exerted on the car’s wheel during acceleration, braking and cornering.

If the races are the same size, remove the first one with a flat-faced punch and heavy hammer, tapping alternate sides and working evenly around the race so as not to tilt and jam it. Be careful not to scratch the inside of the hub.

Which means, that a few months prior, I’ve just hit 210 KPH with broken wheel bearings in what’s essentially a 20 years old coffin on wheels. Yay.

Just a few months ago I’ve had the rear wheel bearings of my E36 replaced. When the mechanic popped them out, he said that the rear right bearing was shot beyond recognition and it was a miracle that it didn’t break.

How unbearable, those bearings look like Lindor balls all melted up. I’m losing my bearings, I think it’s hazelnut Lindors, but i’m not sure if it’s Dark chocolate or not, or milk chocolate bearing a dark top layer. Bare with me here……….., cuz i don’t really care, I’ll eat them both.

To replace bearings, tap the outer races into the hub using the old races as drifts. Be sure to fit a tapered roller race the right way round.

If left to wear down further, a wheel bearing could seize and lock the axle, causing all sorts of additional damage to the drivetrain. Worst-case scenario, the wheel may come off the car altogether, so it’s best to get the car looked at as soon as possible if you suspect a dodge bearing. However, considering the forces that a drivetrain has to counteract during its lifetime of usage, it is impressive how long wheel bearings can last if inserted properly and looked after - depending on the car, original bearings can generally last for comfortably over 100,000 miles.

Fit the thrust washer with its chamfered side towards the bearing. Screw on the hub nut, then adjust the hub. Position a castellated nut so that it lines up with the split-pin hole - by easing the nut, back, not forward - or fit the nut cover if there is one.

Like all mechanical parts on a car that rotates, rub and roll, they tend to wear out eventually. There are several signs of a knackered wheel bearing. The most common is a constant drone, hum or growl from the affected wheel, which will get more noticeable as speed increases or the car turns. You may also notice less responsive steering or speed-dependent wheel wobble. On more modern cars, which often have anti-lock brake sensors integrated into the hub assembly, you might get an ABS warning light on the dash.

They never seize immediately. No need to fear. I have a comparison to make. My Skoda had 5 out of 4 changed in its 175 000 km lifetime. Only one bearing failure might have been caused by an accident. My E46 has had the originals for 245 000 km and 13 years. And none of them seems to be on their way out.

If you are doing only routine lubrication, the outer races remain on the stub. Inspect them: very slight indentations are allowable, but if there is noticeable pitting or scoring you need new bearings .
