- ๐ ๏ธ Ball-pillar receptacle (squeezing) or special fork
- ๐ง Capable keys and heads for 16, 18, 21 mm (depending on the year of issue)
- ๐จ Hammer and mounting for dismantling
- โ๏ธ Penetrating lubricant (for example, WD-40 or analogues) for unscrewing the stiff bolts
โ ๏ธ Warning: Never use a pneumo-impact screw to tighten the ball nut after installation. This can lead to overdrawing and rapid failure of rubber elements. Tighten it with a dynamometer key.
Also prepare a new lubricant to lay inside the support, if you change only the part itself, and not the lever in the assembly. Many manufacturers sell supports already with a poured lubricant, but checking the tightness of the anther is mandatory. High-quality lubricant It extends the life of the node at times.
Step-by-step instructions for dismantling the old support

Insert the removable between the lever and the fist, twist its screw until the finger leaves the landing place. Do not try to knock your finger with a hammer on the thread - you will damage the slicing.
- ๐ Unscrew the nut of the finger attachment ball support
- ๐จ Use the removable to squeeze your finger out of the swivel fist
- ๐ง Unscrew the bolts of the lever attachment to the subframe (if you change the entire lever)
- Original Skoda
- TRW/Lemfรถrder
- Febi/Sachs
- Budget analogues
If you change only the ball support, and not the lever, then unscrew the bolts that attach the support to the lever. Usually there are two or three. Here, too, there may be difficulty in unscrewing bolts due to rust. Use a key extension cord to increase the lever and put in more effort.
Remove the old element and carefully inspect the seat on the lever. There should be no cracks, chips or severe corrosion.

Installation of a new part and final assembly
Before installing a new ball support, clean the seat on the lever from dirt and rust. If you change the support separately, apply fresh grease under the anther, if this is provided by the design. Install a new part and tighten the fasteners. Build quality directly affects the service life of the node.
Insert the finger of the ball support into the swivel fist. This may require little effort, so use the mount for easy lever lifting. Put a new nut on your finger and tighten it from your hand to fix the detail. Make sure the support is flat and not skewed.
Tighten the nut of fastening the ball support with the recommended moment. For Skoda Octavia A7 This point is usually about 30-35 Nm plus the angle of dolope, but it is better to clarify the data in the technical documentation. Use a dynamometer key for precise tightening. This is critical for safety.
โ๏ธ Pre-drop check
Put the wheel back in place and tighten the bolts slightly. Lower the car to the ground so that the suspension takes the working position. Now tighten the wheel mount bolts with the recommended moment. Tightening of wheel bolts It should only be made when the car is on wheels, otherwise you can skew the disk.
After assembly, be sure to check the suspension. Swing the wheel with your hands, make sure there is no backlash. Scroll the wheel to check for no extraneous sounds. If all is well, you can conduct a test trip at a low speed.
Descending and adjusting wheel installation angles
Any interference with suspension elements, including the replacement of the ball support, violates the factory settings of the wheel installation angles. So after the repairs Skoda Octavia A7 The decomposition procedure is mandatory. Ignoring this stage will lead to rapid tire wear and unstable behavior of the car on the road.
