Sharan replaces pressure bearings and flat bearings

Xia Lang pressure bearing is fine on the left and always broken on the right. The original car plus the insurer claims twice, three plane bearings are broken.
The last claim began to ring in less than half a year, getting heavier and heavier and more unbearable.

The performance of the broken pressure bearing is as follows: the slow direction in place, the low sound of the front wheel collapsing, and the clattering of the front wheel spring when the vehicle is slow. When you slowly hit the direction, the hand touches the outer spring of the shock absorber, you can hear the sound and feel the spring moving the vibrating hand, and it can be concluded that the pressure bearing is broken.

The cause of damage to the pressure bearing: it is a common fault of Volkswagen. I estimate that the external cause may be related to not slowing down the stagnant area of the road surface when it rains. The stagnant water on the road surface is generally on the right side. After the right wheel presses the stagnant water area, the water and sand splashes into the shock absorber and dustproof sleeve and into the gap of the plane bearing, causing the bearing to enter the sand and make a noise after the rotation is not smooth. Because the revolver is less splashing, it doesn’t get into the sand and hasn’t broken all the time. The internal cause is caused by the structure of the plane bearing of Volkswagen original factory, the bearing seal is not good, there are cracks easy to enter the water and sand. So I estimate that in order to prevent it from going bad, try not to press the water quickly on rainy days.

There is a VIKA brand pressure bearing on the market. It is introduced that its working structure and sealing performance are better than those of the original factory, which can solve the problem of total failure.
There is also a GTS brand of all-steel plane bearings, which is quite expensive. It seems that refitted riders love to install when upgrading and reducing vibration, and they have strong bearing capacity and do not like bad ones.

“the inclined cover of the pressure bearing of the original model, coupled with the core structure of the VIKA pressure bearing, is assembled into a vika version of Charang pressure bearing, which is installed perfectly. “

After washing, the removed top glue has no damage at all and is as bright as new; the removed plane bearing does not seem to be broken after washing and can be repaired with butter and thrown into the trash can.
Another search: (do not disassemble and replace 09Polo planar bearings to solve the problem of direction sinking and not automatically returning to normal) this is awesome!

Bought the top glue of the original factory (top), the pressure bearing of the original factory (lower left), the mass pressure bearing of vika (lower right, flat plastic cover, and Xia Lang is not universal).

Import top glue of original car

The bottom of the top glue of the original factory.
There is a bulge in the rubber seat to engage with the grooves in the pressure bearing cover.
Because Xia Lang top glue has this bulge, so the price of imported goods has increased several times, except for the bulge, the others are the same as domestic Volkswagen.
This thing probably won’t break easily. It’s quite expensive to buy it.

The top surface of the original factory top glue is marked with an arrow indicating the front and rear direction of the installation.
This thing is universal to the left and right, so as long as the arrow is facing back and forth.
The actual rubber side has a groove bulge, install it toward the outside of the car, the top glue is in the right direction. The groove bulge is the upper left position on the left side in the picture.

Original car import plane bearing

The top surface of the pressure bearing of the original car. The plastic lid has grooves opposite to the top glue.
This nylon plastic cover is beveled, and the pressure bearings of Volkswagen models are flat.

The bottom of the pressure bearing of the original factory. The bottom shell coating is yellow and bright.
The nylon bevel cover covers the iron shell base, and there is a gap between the two.

Also bought a domestic vika improved Volkswagen pressure bearing.
The plastic cover is flat and has no inclined surface.

The top surface of the improved pressure bearing made in China is silver in galvanized layer.

The bottom surface of the domestic improved pressure bearing, the galvanized layer is silver.

Remove both bearing plastic lids.
The left is improved silver and the right is yellow from the original factory.

In the original factory, the ball in the bearing has a cage, and the soft plastic seal of the inner ring is transparent.

Improved model.

Improved model, many balls, no cage. The soft plastic seal of the inner ring is black.
Remove the top tile, with balls, a lot of bearing oil.

Improved bearing bottom bush

Replace the bevel lid of the original factory with the flat lid of vika. In this way, Xia Lang can use the improved pressure bearing.
According to the introduction, the improved model has multiple seals, various improvements, it is not easy to enter the sand, and the ball has a large bearing capacity. Balabala., should be all right.

“Note: when replacing the two lids, the soft plastic in the innermost ring of the bearing should be pressed inside by the inner edge of the nylon lid, operate gently, and properly use a small flat screwdriver to smooth through it. Do not use brute force to hard press and buckle, otherwise, the most inner ring soft plastic flanging and pleating, this is an important sealing structure, broken must enter the sand. “there is a slight deviation in size, which can be ignored.

Spend money to load the car, the nearby car repair shop is not very professional, lazy, do not remove the brakes to reduce vibration. There is no or no knowledge of the special tools for the Volkswagen 3424 sheep horn separator, and the shock absorber cannot be removed from the base. All kinds of fights, a sledgehammer, the tubing dangling the brake disc, the ball cage oil dripping all over the floor. Dismantling a shock absorber is simply, all kinds of special forces are not going well, and finally end up with the loss of the front glass edge clamp and the warping deformation of the brake disc protection iron pressed by a crowbar.

Put on a new flat bearing, the world is quiet! =
Buckle the small lid at the top of the tower to prevent the nut from rusting.
Another four-wheel positioning was done, the front beam angle was adjusted, and the high speed did not deviate to the right.
-gorgeous separation line–

There is a lot of sediment in the detached plane bearing.

Sediment

The top glue removed is the same as the new one after being washed. It’s not bad at all. There’s no picture here.
Remove the bevel cover of the original plane bearing, wash it almost the same as the new one, and have no damage. There is no carburetor cleaner. I washed it with facial cleanser.
This lid is matched with vika or cheap domestic pressure bearings, which can be assembled into Sharon pressure bearings. Make sure that the soft edges of the inner ring are not pleated when fitting.

Wash clean

Wash and assemble before taking it apart.
The stamping iron seat is originally integrated with the plastic base of the bearing, but the small clip on the outside of the plastic base is worn flat, as shown in the picture: the two are disintegrated and separated. I use two good AB glue to re-glue the two together, so that they will not suddenly fall apart during installation.

Disintegrate

Structural composition. I don’t see any serious damage.

Cage

Install the bearing back on the base.

Put the lid back and be careful not to crush the soft edges of the plastic. It’s not oiled yet. It’s smooth.
Put this cover on the new and improved bearing to fight again.

The cage, there is no abnormality in the rolling balls, they are all smooth and translucent, and there is no trachoma.

The upper and lower bearings of the bearing wrap around the balls and then fit together.

The rotation is very smooth.

There is no blue lithium-based grease, and it is tested and repaired with plastic gear oil. This gear oil is extremely long-lasting.

Because the original car received sand and sand, the rotation was not smooth, and the place was subjected to a large rotating torque. The clips on the plastic base of the bearing were ground flat and separated from the iron base.
I used AB glue to glue it back to repair the positioning.

After turning around, I didn’t wash it completely. After turning around ten times, I actually occasionally salad it.
After thoroughly washing the sand with carburetor cleaning agent, apply the ball bearings with blue lithium-based grease, and throw them into the trash can after repair.
