Automobile wheels spin round
thanks to the miracle of wheel bearings. The bearings themselves contain
rollers that spin around inside a cage.auto oil seals Isuzu. Wheel
bearings are often tapered against the coned races in which they spin in
order to handle the lateral forces placed against the wheels when the
vehicle turns. Given the right grease and care, most wheel bearings
should roll without complaint for 100,000 miles or more. Neglected
bearings will tell another tale.
Modern Realism
Wheel bearings need grease like tires need air. A swell time to inspect and grease up the wheel bearings is when wrestling with brake pads or brake caliper removal. Halfway there is always a good reason to press on. While some bearings are relatively easy to inspect and service, others are pressed onto axles or worse – of the captured bearing variety. Specialized tools and procedures make captured bearing service best left to the professional. Front wheel bearings on rear-drive cars are fairly basic.auto oil seals Isuzu.
Whine and Grind
When bearings go bad the noise is usually speed specific – clicks, groans, rumbles and noise that varies according to the speed of the spinning wheel in which the bearing is contained. A quick way to check wheel bearings without disassembly is to jack the wheel in question up off the ground, grab it from both the top and the bottom, and attempt to move it. There should be very little or no movement. Lots of slop? Read on.
Bearing Inspector
Reading bearings involves taking a look. Peer closely for loose or broken tapered rollers, scored race or roller surfaces, or excessive play in the assembly. The shiny surface of a bearing is hardened, and should be of a uniform color. Hot spots, different color lines or scoring indicate wear through to the softer metal underneath. Worst-case scenario? Friction created by a cooked bearing can generate enough heat to shear an axle. One of your own wheels bouncing down the road ahead of you is never a good thing.auto oil seals Isuzu.
Bad Cholesterol
Top quality high-temperature wheel bearing grease is the key to wheel bearing longevity. Brakes convert vehicle inertia into heat as they impart whoa. A lot of heat. Low temperature or chassis grease will liquefy and slip-up the brakes. The other rule of grease is that grease types are not always compatible. Out with the old and in with the new. Use solvent to remove grease and dirt from bearings. Let the wheel bearing air dry. Always relubricate with high temperature wheel bearing grease of the same type.auto oil sealsIsuzu.
Perfect Match
Replace wheel bearings, seals, races, and so on as a matched set. Bearing quality, as we recently discovered, makes a difference. Spending some extra money for good bearings now can save time later. A seal and race driver tool set makes seating in the races and seals a breeze. A solid drift works much better than a screwdriver for batting bearing races out of the hub. Always use a new cotter pin as a finishing touch. One penny is cheap insurance against wheels liberating themselves from axles.auto oil seals Isuzu.
