Step-by-step instructions to removing wheel bearings

Here you can get removing wheel bearings. Here we provide Step by step instructions to removing and Install new wheel bearings.

Wheel bearings are an important part of a vehicle’s suspension. Usually located within the wheel’s hub, rotor, or drum, bearings help the wheel rotate smoothly when the vehicle moves. If you notice a humming or whirring noise while you’re driving or your ABS light turns on, it’s going to be time to vary your bearings. you’ll economize by changing your own wheel bearings instead of going to a mechanic, but if you are doing so, use caution — the bearings could also be small, but they’re very important.

Park your vehicle on a flat surface

like most types of auto maintenance, you’ll want to require all necessary precautions when changing your vehicle’s wheel bearings to make sure your safety. The worst thing which will happen when changing your wheel bearings is for your vehicle to suddenly shift or roll away. Before you begin, park your vehicle on A level surface. Put the vehicle in park (or, for manuals, 1st, reverse, or neutral) and be sure to place the parking brake up.

Note: Every vehicle is different. The instructions below are intended as a general set of guidelines and thus won’t perfectly fit every vehicle. If you run into problems while attempting to vary your wheel bearing or have doubts after you finish, it’s extremely knowing enlist the assistance of knowledgeable mechanic. Doing so can save time, prevent future headaches, and economize within the end of the day.

Use wheel chocks to secure wheels whose bearings you aren’t replacing

added stability, it are often smart to use sturdy chocks to hold your vehicle’s wheels in situ. Obviously, you’ll be wanting to use chocks on the wheels you do not plan on modifying, because the wheels you are doing modify are going to be elevated off the bottom. for example, you’d place wheel chocks behind the rear tires if you’re fixing a front wheel bearing and behind the front tires if you’re working on a rear wheel.

Loosen the lug nuts and lift the wheel using a jack

For proper access to the internal components of the wheel whose bearings you’re replacing, you will need to elevate the wheel. Luckily, most vehicles come with a jack for just this purpose. Before you lift the wheel, however, you’ll want to slightly loosen the lug nuts with a tire tool , as breaking their initial resistance is harder without the bottom holding the wheel steady. After this, carefully lift your wheel.[3] If your vehicle doesn’t come with a jack, you’ll got to buy a suitable jack at an auto supply store. See wiki How’s guide the way to change a tire for help elevating your vehicle’s wheel.

  • to stop dangerous slippage, confirm that the vehicle is securely seated on the jack which the jack is flush with the bottom before attempting to lift the wheel. it is also important to form sure the jack touches the vehicle on a sturdy, metal piece of the undercarriage, instead of on fragile plastic molding, because the weight of the vehicle can damage the latter.
  • Most vehicles have jack points where the frame has extra support to lift the vehicle. it is best to see the owners manual to find out the simplest place to position your jack.
  • it’s also extremely wise to use a safety jack represent added support within the event the ground or scissor jack fails.

Unscrew the lug nuts and remove the wheel

he lug nuts, which you ought to have already loosened, should come off easily. Remove these and put them during a safe place where you will not lose them. Next, remove the wheel itself. It should come freely.

  • Some wish to keep track of the lug-nuts by removing the hubcap, turning it over, and using it as a kind of “plate” to contain them.

Remove the brake caliper

using a socket and a ratchet, remove the caliper’s bolts. Then, remove the caliper itself using a screwdriver.

  • When removing the caliper, take care to not let it dangle freely, as this will damage the brake hose. Instead, hook it on a secure a part of the undercarriage or use a brief length of string to tie it in situ . A bungee or a bent wire hanger are two additional ways to secure the caliper.

Remove the dust cover, cotter pin, and castle nut

In the center of the vehicle’s exposed rotor should be a small metal or plastic cap called the dust cover which protects the components holding the rotor in situ. Since you’ll need to get rid of the rotor, the cap and the components it protects will need to go. Usually, the dust cover are often removed by gripping it with calipers and tapping the calipers with a hammer. Inside, you will find the castle nut, usually secured with a cotter . Remove the cotter with pliers or wire cutters, then unscrew the castle nut and take away it (and its washer).

  • make certain to stay these small but important parts somewhere that they will not be lost!

Remove the rotor

Place your thumb securely on the peg within the middle of the rotor assembly. Firmly (but somewhat gently) bump the rotor itself with the palm of your other hand. The wheel’s outer bearing should loosen or fall out. Remove the outer bearing. Finally, remove the rotor itself.

  • If the rotor gets stuck, you’ll use a rubber mallet to hit it loose. This can, however, damage the rotor, so it is best to use a mallet as long as you’re not planning on reusing an equivalent rotor.

Unscrew the hub bolts and remove the old hub

The wheel bearing is inside the hub, which is usually held in situ with several bolts that screw in from behind. These bolts are often tricky to reach because they’re tucked away within the undercarriage, so you’ll want to use a thin wrench and/or a breaker bar to loosen and take away them. When you’ve removed the bolts, take the hub off of the axle.

  • Note that if you’ve purchased a new hub assembly, at now, you’ll install the new hub and put the wheel back together and you will be finished. to put in a new set of bearings inside the hub, read on.

Disassemble the hub assembly

To gain access to the bearings, you will need to require apart the hub. you’ll likely got to use a wrench (and/or a hammer) to get rid of the top of the hub and any anti-lock brake wheel which will be a part of your hub. Then, you’ll got to use a specialized “puller” tool to get rid of the central bolt. The bearing assembly should break easily.

Remove races and clean the knuckle

Removing the bearing assembly’s races usually means physically breaking them with a grinder or hammer and chisel. due to this, you’ll be wanting to have replacement races ready. After removing the races, it is a good idea to wash the within of the bearing assembly round the knuckle.

  • There’s usually many grease and dirt here, so have many rags handy.

Install new races and new wheel bearings

Set new races in place within the bearing assembly with a few taps from a hammer. Finally, grease a new inner bearing and install it within the assembly. make sure the bearings are properly aligned, that they are pushed in as far as they will go, which any sealing rings are flush with the surface of the assembly.

  • Use many grease for your bearings. you’ll apply the grease by hand or with a special “bearing packer” tool. Rub many extra grease round the outsides of your bearings and any sealing rings.

Replace all parts in reverse order

Now that you’ve got changed the bearings, basically all that’s left to try to to is to re-build your vehicle’s wheel. do not forget, however, that this suggests installing a new outer bearing after the rotor is in situ. Put the hub assembly back together and install it on the axle shaft. Put the rotor back on and secure it in situ with its bolts. Install a new, well-greased outer bearing at now. Lightly tighten the castle nut and secure it in situ with a new cotter. Replace the dust cap. Put the caliper and restraint back in situ and secure them with the appropriate bolts. Finally, put the tire back in situ and secure it with lug nuts.

  • When you’re all done, carefully lower the car backtrack to the bottom together with your jack. Congratulations – you’ve just changed your wheel bearings.
