Front stabilizer strut. Causes of wear and self replacement

The stabilizer struts are a necessary link between the suspension and the body. They keep the car from a strong roll during cornering, acceleration and sudden braking. The need to improve this element of the suspension appeared with increasing speeds of cars. The faster the car travels, the more inertia will act on it.

To date, the simplest device is the suspension "McPherson". It is installed on low-end models, such as Ford Focus, easy to maintain. Stabilizer bars are part of this design.

Design features

The stabilizer strut is a metal bar with fastenings on the ends. All front struts have the same shape, but there are some differences in the material of manufacture, length and method of attachment.front stabilizer bar

For example, in Ford Focus, the front stabilizer bars are made of 25 cm aluminum.At their ends there are multidirectional ball joints: one is turned relative to the second one by 180 degrees. On the strut rack there is a landing pad for mounting the stabilizer bar.

Why does the front stabilizer rack fail?

The worst enemy of the suspension is the lack of roads and potholes. The more often and more strongly the surface relief changes, the more actively the nodes of the mechanisms react, the more stabilizers have to work.

Lurking danger conceals parking, or rather, the difference in the level of the left and right wheels. The owner of the car, which constantly leaves the car parked with one wheel on the curb, often changes the front stabilizer bar.replacement of the front stabilizer bars

The first reason

When the car is tilted without moving for a long time, the anthers of the ball bearings (rack mounts) are stretched, cracks appear on them, and then ruptures. Under the boot gets dirt and water. Ball joint fails. Often suffers mount with stabilizer, as it is closer to the ground.

PReason two

On an uneven surface, the ball bearing is constantly in the working position, that is, the ball in the sleeve is inclined to one part of its wall. As a result, the oil from the side against the wall of the sleeve is squeezed out.Uneven distribution of grease leads to the deformation of this wall and cracks in it. Front stabilizer rack fails.

Self-diagnosis

When in the front of the suspension while driving on a rough road, something starts to knock, you can diagnose the damage yourself:

  1. We put the car on a flat place.
  2. With force we swing it from side to side. If you hear a knock, then this is really the front stabilizer strut.
  3. Turning the wheels all the way.
  4. The assistant continues to rock the car with force.
  5. We push the hand over the wheel and test the ball bearings. During the swing, there should be no play between the support and the stabilizer.

If there is a knock and a backlash, is it possible to solve the problem on your own, and not to contact the service station? Replacing the front struts on the Ford stabilizer is a simple process. It is enough to have a key - "17" and a hexagon - 5 mm.

Independent replacement of the front stabilizer struts

Safety precautions: the car must stand on the handbrake and with wheel chocks. In addition to the jack, you must have additional support.front stabilizer ford

Jacking up the car and remove the wheel.With the help of the hexagon fix the finger so that it does not start to turn. The key unscrew the nut, release the upper and then the lower mount.

In order to remove the rack, you need to put an emphasis under the ball support and slightly lower the jack to the level until the rack is level.front stabilizer ford focus

Installing the new front suspension stabilizer is in the reverse order. It happens that the fastenings of the new part are not joined with the fasteners on the stabilizer and the shock absorber. In this case, you can use a small montage. Having missed it between the steering tip and the stabilizer, slightly bend the stabilizer downwards, without making an effort not to damage it.

"Ethnoscience"

The stabilizer rack is a consumable part, and it is inexpensive. However, it is quite possible to reanimate the ball bearing and give it another life:

  1. Remove the stabilizer rack.
  2. Remove the boot.
  3. Clamp the finger of the hinge in a vice, and pull the second end of the rack upwards.
  4. To get a finger, a lot of effort is needed.
  5. Cut out a cross-shaped seal from a plastic bottle so that each of its strips covers a quarter of a spherical part of a finger.
  6. We erase the old one and apply fresh grease on the ball and close it with the cut-out sealant, evenly distributing its sides over the entire area.
  7. We press the design in a vice so that the finger is back in the support of the rack.
  8. Installing a new boot.front suspension stabilizer bar

After such a repair, stabilizers will last about six months. There will be enough time to select and purchase a new part.

Replacing the rear stabilizer

The rear stabilizer "Ford Focus" are the bolts that are put on the damper bushings (they are needed to dampen the vibration between the stand and the lever). There are nuts on both ends of the bolt. Rear racks are mounted in the rear lower arm through the eyelet.front stabilizer bar

To replace the rear pillars will require an inspection pit. The key "15" or "17" unscrew the nuts. We take out the old rack and in its place we insert a new one.

Rear racks are changing many times faster and easier than the front, the rear wheel does not need to be removed.

If the nuts are rusty, use a penetrating lubricant WD-40. Within 5 minutes after application, rust will come off the nut and it will easily loosen.
