We work together on a viewing ditch
Jacking the beam and removing the front wheel
Under the front end of the frame we substitute a reliable factory-made stand with a load capacity of at least 2 tons and a height of 700 mm
We lower the jack and leave it under the beam or, for convenience, rearrange it under the hub
In order not to damage the brake hose, it is advisable to remove the front brake caliper and tie it to the frame
With a “24” head, we unscrew the four bolts for fastening the ladders.
Taking out the ladders.
Remove the spring cover.
Holding the bolt of the front eyelet of the spring with the “22” key, unscrew the nut with the “24” head.
We knock out the bolt with a beard or a suitable rod.
We also unscrew the nut and knock out the bolt of the rear spring mounting (to the earring)
Remove the spring.
Cleaning the spring from dirt
Insert the bolts into the hinges of the spring. We stretch the cord between them and measure the spring deflection arrow
The deflection arrow should be 147 ± 10 mm for a two-leaf spring, and 135 ± 5 mm for a four-leaf spring.
If this value is less, we replace the entire spring.
Unbend the clamp, striking with a hammer through another hammer.
Having clamped the spring in a vise, with two “17” keys we unscrew the nut of the centering bolt and remove the bolt.
Disconnecting the leaf springs.
We clean the inner surfaces of the spring sheets from dirt and rust.
To replace the rubber-metal hinges, put the spring eyelet under the press.
Press out the sharn ir.
To facilitate the pressing of a new hinge with a file or an emery wheel, we make a lead-in chamfer on the edges of the metal plates from the end of the hinge.
Compress the hinge with a band clamp.
Lubricate the hinge with soapy water and, using a mandrel, press it in on the same press.
Having lubricated the sides of the sheets facing each other with graphite grease, we assemble the spring.
In this case, pay attention to the difference in the design of the front and rear lugs of the spring.
Unscrew the nut and take out the bolt of the spring earring.
Remove the plates of the spring earring.
While holding the bolts of the earring bracket with the “14” key, with the “17” head, unscrew the four nuts and remove the bracket
Replacing the rubber-metal hinge of the bracket
Install the removed parts in reverse order, tightening the ladder nuts evenly.
The vertical protrusion on the spring pad must face the longitudinal axis of the vehicle.
The final tightening of the nuts of the rubber-metal hinge bolts should be carried out on a loaded vehicle with straightened springs.
This is necessary for the hinges to work properly.
Similarly, we disassemble the spring and replace the rubber-metal hinges on the other side of the car.
Replacing the rubber buffer
Holding the bolt with the “17” head with the extension, unscrew the nut with the “19” key
Remove the buffer together with the bolt, washer, bushing and cup
Install the buffer in reverse order.
