Remove the steering knuckle from the rack.
Clean the knot from dust and dirt.
Clamp the column 4 in a vise and knock out the locking pin with the barb 1.
Knock out plugs 2 on both sides of the kingpin.
To do this, install the key on the flats A of the king pin 3 and knock out the plugs with a hammer on the key in both directions.
Knock out the kingpin 6 and disconnect the steering knuckle 1 from the rack 2, while removing the ball bearing 5 with a protective cap.
Remove the two rubber protective rings 4 and press the needle bearings 3 out of the rack lugs.
Assembly is carried out in the reverse order of disassembly. When assembling, align the pin holes on the kingpin and the lugs of the steering knuckle.
Needle bearings should be pressed flush with the end of the undercut under the plug using a brass mandrel with an outer diameter of 29.5 mm and a guide shank with a diameter of 20 -0.50 and 20 -0.10 mm (along the inner diameter of the bearings).
When installing the bearings, the lubrication holes in the bearing housing and the strut head must match.
Before installing the kingpin, it is necessary to lubricate the bearings with gear oil and select the adjusting washer so that there is a gap of no more than 0.2 mm between the lugs of the steering knuckle and the rack.
The kingpin plugs must be replaced with new ones. The new end caps are spherical, to fit snugly into the rack ears, straighten them through the flat mandrel when installing.
It is recommended to install a new pin. Finger heads should be directed forward in the course of the car.
It should be borne in mind that the final tightening of the threaded connections of the lever fastening is carried out only on the suspension, which is in a loaded state.
Pin nut tightening torque 120 - 200 Nm (12.0 - 20.0 kgcm).
Lubricate the kingpin bearings with gear oil through the grease fittings.
Adjust wheel alignment. (Descent collapse GAZ-3110)

Remove the front suspension strut assembly with the steering knuckle and hub from the car.
- 1. We turn off the grease fittings so as not to damage them during subsequent disassembly.
- 2. With strong blows of a hammer through a barb or a similar tool, we knock out the locking pin.
4. We rest the chisel against the edges of the flat, and tapping on it with a hammer, we shift the kingpin along its axis, first to one side and then to the other side, squeezing out the plugs with it.
6. With light blows of a hammer through the beard we knock out the kingpin
- 7. Removing the stand.
- 8. Remove the thrust bearing with a protective rubber ring
- 9. We remove the adjusting washer (the washers can be of five sizes from 0.8 to 1.6 mm, the pitch is 0.2 mm).
- 10. Using a screwdriver, pry off and remove the sealing rubber rings of the needle bearings from the holes.
- 11. Using a hammer through a mandrel of a suitable diameter, we press out the needle bearings.
- 12. We install the kingpin in the reverse order, taking into account the fact that two holes are made in the needle bearing housing.
When installing the lower bearing, one of its holes must be aligned with the hole for the grease fitting, and the other with the channel for lubricating the lower threaded hinge of the rack
At the upper needle bearing, we achieve alignment of one of the holes with the channel of the grease fitting.
The thrust bearing is filled with grease during assembly.
During operation, the kingpin wears out only on one side. To increase its service life, it has two flats for the locking pin.
If the lateral play of the kingpin exceeds 0.3 mm, you can knock out the locking pin, turn the kingpin 90 ° with a wrench until the second flat is aligned with the hole and reinstall the pin.
Removing the king pin or replacing the pin with a new one is not required.
