The quality movement of your Daewoo Nexia car, its convenient operation and safe driving are determined by many factors. The condition of the rear wheel bearings is important. We'll talk about them today.

You will learn how to identify a broken wheel bearing on a Nexia and how to fix it yourself.

When do you need to change the wheel bearing on a Nexia?

You will have to pay close attention to their lubrication and monitor how these parts work. Since this determines how the wheels rotate, and, accordingly, the reliability of the car.

Usually, after 50,000 km, it is worth thinking about replacing the bearings. This is if you operate your car efficiently and correctly. More often than not you have to do this a little earlier.

Why does the rear wheel bearing fail and need to be replaced? I will tell you in an accessible way.

• water and dirt penetrate through the seals;
• lubricant may be leaking;
• the poor quality of our roads, driving on which is not very beneficial for all parts of the car;
• wear of the axle shaft seating surface;
• the rear hub is worn out, the drum is unbalanced;
• The rear suspension has other problems.

The wheel bearing is located in the rear wheel, namely the hub. Inside, it is attached to a part of your car, such as a brake drum.

The rear hub is made up of two parts: a large roller bearing located on the inside and a small one located on the outside.

Wheel bearings for front wheels of Daewoo Nexia

To replace the wheel bearing correctly, you should be careful when dismantling, maintain cleanliness, replace the axle bearings at the same time, avoid distortions when installing new bearings, and avoid using sharp tools when replacing.

There are certain manufacturers who thoughtfully make some devices with which you can mount or dismantle wheel bearings without directly removing them from the car. If the design of the car provides for the presence of an ABS system, then this can save you time during replacement, as it will help eliminate subsequent checks of the chassis geometry.

The front wheel bearing is pressed into the steering axle housing and secured in it with two retaining rings, which are located in the grooves of the housing on both sides of the bearing. The front hub assembly is pressed into tension in the inner race of the bearing. The front wheel bearing is not adjustable. If play appears, the bearing will require replacement.

Checking which part is broken

Read this article and you will learn how to independently, efficiently, and, guided only by this article, replace the rear wheel bearing for this car brand. You can make diagnostics, change the previous one and install a new bearing.

It goes without saying that in order to begin any repairs, you must know exactly where the breakdown occurred. I'll tell you how to understand that the rear wheel bearing is broken.

• the chassis play can be felt even manually;
• the wheel behind is knocking, very noisy, a strange hum is heard. As you increase your speed, all of these symptoms get worse;
• lubricant flows through the seals;
• the raceways are deformed and you hear
• strong grinding. The separator becomes deformed and the rollers fall out.

Now you know that the breakdown is in this rear wheel bearing assembly.

I’ll also tell you one important detail when replacing. The engine size of your car has absolutely no effect on the progress of the repair. The number of valves can also be eight or sixteen.

Diagnostics of the rear bearing, signs of failure

Before you begin repairs, be sure that it is the wheel bearing assembly that has failed; the signs of this are as follows:

1. Chassis play, felt by hand;
2. Noise and hum of the rear wheel increases as speed increases;
3. Leakage of lubricant from oil seals;
4. Grinding and squeaking occurs when the raceways are destroyed, the cage is deformed, and the rollers fall out.

The front wheel bearing has similar signs of failure.

Procedure for checking the Daewoo Nexia wheel bearing:

1. Raise the rear of the car with a jack;
2. Rotate the chassis and listen to the sound of rotation;
3. Check the play by moving the wheel axially.
4. The video shows the process of diagnosing and checking rear wheel bearings.

Rear bearing diagnostics

It is important to know:

The repair process does not depend on the engine size (1.5, 1.6 or 1.8, n150), as well as on the number of valves (16 valves or 8 valves), follow the step-by-step instructions, and then replacing the wheel roller bearings will be done without errors. Repairs are carried out in a similar way on the Nexia hatchback 1997.

We change the bearing. Detailed instructions on how to remove the drum and broken wheel bearings

First of all, you need to remove the car from the brakes and be sure to put chocks on the front wheels. You do all this on a surface without tilting and in good lighting.

1. Raise the car on a jack and remove the rear wheel. The cap protecting the hub nut must also be removed. I would also advise installing a special support under the car to make sure that the car will not move when standing only on a jack.

2. Unscrew the hub nut, pulling out the cotter pin. In theory, if the nut threads are in order, there should be no problems here. But if there is still damage to the thread, use the head.

3.Next comes the removal of the drum and hub, using a screwdriver. The roller cage is pulled out. It is located in the outer wheel bearing.

4.Look at the brake disc, at the back you see the hub. Now it is necessary to press out the outer parts of the roller bearings. You can use either a screwdriver or a chisel along with a hammer.

5.The hub hole has special gaps, which are very convenient for removing the rings without any problems. When you have pressed out all the parts, the seating surface is thoroughly wiped.

Now I will tell you to install new parts.

Bearing adjustment

The following question arose for me: the other day I changed the wheels at a service center, and the mechanic who changed the wheels somehow “in the air” determined that “you need to adjust the hub bearings.” Maybe he expected me to immediately ask to do this, who knows. I just nodded my head in response. Interestingly, no more than a couple of thousand km. ago I did TO-40000 and asked to carefully look at both the suspension and brakes, while in my opinion the bearings are also inspected (done in Kardoctor). And the technician who did the inspection did not find anything that needed replacement/adjustment.

The question, strictly speaking, is this: was the phrase about the need for regulation not a banal attempt at divorce?

The front ones are not adjustable, the rear ones - yes, is there noticeable play in the rear wheels when suspended?

Replace the rear wheel bearing on a Daewoo Nexia yourself

1. The outer part of the bearing, which is larger, must be pressed into place. Use the old clip on top.

2.In a smaller bearing, the inner and outer rings are thoroughly lubricated. I advise you to use lubricants from trusted manufacturers. I include these: the MOBILE brand or LITOL-17.

3.The oil seal is pressed onto the holder that you previously inserted.

4.Next, in order, we mount the external wheel bearing. Head 30 will help with this. Apply lubricant again and place it inside the holder of the outer part.

5. The fastening nut is secured with a cotter pin. The drum and hub are placed on top of the rear axle shaft. These spare parts are installed in such a way that the hub holes and the gaps on the drum match.

6. After making sure that all the holes line up, you tighten the brake drum mounting bolt. Place the cap to protect the hub nut and put the wheel in place.

How to adjust new Daewoo Nexia rear wheel bearings yourself

In order for the installed hub bearings to serve you for a long time, they must be adjusted correctly. There is only one adjustment method.

You will need to tighten the nut with a torque wrench. Read here how to make this adjustment.

— after screwing the locknut, it is tightened to the limit;

— move the drum a little in one direction or the other, but do not put on the cotter pin. We do this so that the lubricant lies evenly on the surface;

- using a torque wrench, tighten the nut to 2.5. Turn the drum again and the locknut goes back, up to 180 degrees;

— we re-tighten the locknut also by 2.5. Don't forget to pin it.

The correct adjustment is complete!

Adjusting the rear wheel bearings of Daewoo Nexia (8/16 valves sedan and hatchback, n150)

Proper adjustment is an important criterion for wheel bearing life. The only correct method of adjustment from a mechanical point of view and according to official operating instructions is to tighten the nut to the specified torque using a torque wrench.

Step-by-step adjustment instructions

1. After screwing on the locknut, tighten it by hand until it stops.
2. Without putting on the cotter pin, roll the drum in both directions to distribute the lubricant.
3. Using a torque wrench, tighten the locknut to 2.5 N*M.
4. Roll the drum in both directions
5. Unscrew the locknut 180 degrees.
6. Retighten the locknut to 2.5 N*M.
7. The bearing assembly is now adjusted correctly. Be sure to install the cotter pin. The whole process is also shown in the video.

Adjusting the rear wheel bearing

What size and bearing number should you choose for your car?

The bearing installation scheme is called “in the spacer”. In accordance with GOST, bearings are marked as follows:

• internal number 6-7006A (in accordance with ISO - L45449/L45410);
• external number 6-7703A (in accordance with ISO - LM11749/LM11710).

The accuracy level is selected number six. Model A for increased load capacity.

I will suggest you a reliable manufacturer of wheel bearings. I consider the Russian Volzhsky bearing plant to be one of these.

Foreign manufacturers are also good. These are brands from Germany: FAG and SWAG. Spare parts from the French manufacturer NTN - SNR have proven themselves well.

A few more tips for performing wheel bearing repairs and how to perform service

1. When removing the drum and shoes, be careful and make sure that the roller bearing does not fly out.

2. It is recommended to replace roller bearings on both sides at the same time.

3. Replace the axle shaft immediately after you notice mechanical defects.

4.Check regularly during vehicle operation for the presence of lubricant and whether lubricant is leaking. Make sure that the bearing assemblies and seals are sealed.

5. If the adjustment is done according to all the rules and properly, the permissible clearance in the axle should be from 0.03 mm to 0.13 mm.

That's all you need to know to repair, replace, adjust and maintain rear wheel hubs for the Daewoo Nexia.
