The wheel bearing is a suspension element that supports part of the vehicle support. It is mounted on both the front and rear axles. This element serves for a long time. However, after a while, the car will need to replace the wheel bearing. Renault Logan is no exception. How to determine the malfunction and replace the part yourself? We will talk about this in our article today.
About Resource and Symptoms
The manufacturer claims that Renault Logan does not require the replacement of the front wheel bearing for the next 150 thousand kilometers. Practice shows that this element is really a resource.
Moreover, the bearing can last 200 thousand. His main enemy is moisture. If the case of the element is deformed and water gets inside, the bearing instantly crumbles. Corrosion processes in it are unacceptable. Therefore, as soon as the lubricant disappeared in the mechanism and rust began to grow, it will emit a characteristic hum. With increasing speed, it intensifies. Unpleasant sound can be heard from both the front and rear of the car. If so, the machine urgently needs a wheel bearing replacement. Renault Logan is equipped with four hub elements.
How to accurately determine the breakdown?
To find out on which of the wheels the bearing scattered, you need to jack each of the parts of the car and check how freely the disk rotates. If it plays backlash and at the same time makes a characteristic hum, then the car needs a wheel bearing replacement. Renault Logan may ride with this malfunction, but there is a risk that the wheel will jam. This will result in uncontrolled skidding. You can get to the place of repair with such a bearing without a tow truck. However, it would be unsafe to drive a scattered item on purpose.
How to choose a new part
It should be noted that the cars of the Logan model came both with an anti-slip system of wheels and without it. Replacing the wheel bearing Renault Logan with ABS does not differ in special tricks. However, the part has its own characteristics. When buying, check with the seller what type of bearing the bearing is (with ABS or not). If you put an anti-lock element on a car with ABS, the corresponding yellow llama will constantly light on the instrument panel.
How much will a Renault Logan wheel bearing replacement cost? The price of the original product from FAG is from three to five thousand rubles. For magnetic stripe bearings (for vehicles equipped with ABS), the price will be higher. There are also a number of analogues. Car owners respond positively to the following manufacturers:
The cost of such products ranges from one and a half to two and a half thousand rubles.
When choosing a new bearing, check the dimensions of the element. There are frequent cases when the non-original does not correspond to the actual diameter. The inner ring size (landing) is 37 millimeters. The outer diameter is 72 millimeters. Width - 37 millimeters. These parameters are applicable for both types of cars - with and without ABS.
Instruments
To replace the wheel bearing successfully, you need to prepare the following set of tools:
- Wrenches and heads.
- Screwdriver
- Round pliers.
- Hammer.
- Jack.
- Press or vise.
In order not to overtighten the wheel bearing nut, it is also recommended to use a torque wrench. What can a wheel bearing replacement do without? Renault Logan has a special hub design. And, to remove the bearing outward, we need a special puller. It is called so - for wheel bearings. The tool looks as follows.
Its cost is about a thousand rubles.
Self-replacing rear wheel bearing
Renault Logan is installed on a lift. If there is none, you need to hang out part of the body with a jack (on the side where you want to change the item). First, you need to break the hub nut with a key of 30. An important point is that the car should not stand on the handbrake (if possible, install backtracks). Next, the brake drum is disassembled . After they move to the circlip. Since it sits tightly in the landing hole, you need to pick it up with a screwdriver.
Next, remove the hub bearing cap. Using a puller, the crumbled element is pressed out. Next, the inner cavity of the hub is cleaned of contaminants. You can use a piece of rags and any solvent. Further this place is carefully processed with lithol. Since the grease is quite thick, it is recommended to apply it with a screwdriver or wood chips.
Next, a new bearing is pressed into the seat. The assembly of elements is carried out in the reverse order.
An important point - the hub nut is tightened with a force of 175 Nm. Twist the element so that there is a slight backlash of 1 degree. Pressing itself is done using the load on the outer ring of the bearing. It is important not to break the clip during installation. Otherwise, it may fall apart at the first corner.
Front axle
How is the wheel bearing replaced on the front axle? Renault Logan jacks up on one side with its own hands. It is also required to unscrew the hub nut. In general, the replacement process is almost no different from the previous case, but there are some nuances here. For example, to dismantle a bearing, you need to disassemble the knuckle.
This can be done using a standard set of keys and heads. After extraction, the knuckle is clamped in a vice. Next, with the help of a hammer, carefully knock out the hub. In order not to damage the element, use a mandrel of the appropriate diameter. Taking out the hub, we find on it a part of the inner ring. We also change it to a new one.
Further, the bearing is pressed out, followed by its replacement and installation. As in the previous case, the seat is thoroughly cleaned and treated with lithol. The fist socket is also coated with grease. After installing the part, the hub is pressed into the stop. The inner ring is supported by a stand. The steering knuckle is installed in the reverse order. After the work done, check the installation and the reliability of the pressing-in elements. The caps should be carefully fixed, and the wheels should be parallel to each other. Otherwise, rolls are possible at bends.
Conclusion
So, we figured out how to replace the front and rear wheel bearings on a Renault Logan. As you can see, the procedure is not very complicated and can be done by any motorist. Experts recommend changing the wheel bearing in pairs. This eliminates the need for an immediate replacement of an adjacent element and saves time in the future.
