In the article, we will consider the replacement of shock absorbers and front suspension springs
We prepare the car and install it on a lift or a viewing ditch
Shock absorber replacement
Unscrew the lower shock absorber nut
Remove the shaped washer, installed with a bulge to the rubber bushing
We also unscrew the top fastening nut and remove the washer
Using a large screwdriver, we pull the upper and lower shock absorber lugs off the axles
Remove the upper and lower inner washers
Remove the rubber bushings from the shock absorber lugs
If it is necessary to replace the lower shock absorber axle, unscrew the nut with a 22 wrench
Through a drift with a hammer, we knock out the axle and remove it from the hole
We install all the parts in the reverse order, applying grease to the axle cone and replacing the rubber bushings
Removing and disassembling the spring
Hang out the front of the car by placing stops under the frame
Remove the front wheel from the desired side
Using a 22 head, we evenly loosen and unscrew the four nuts of the spring ladders
Remove the ladders and spring cover
We loosen the nut of the upper fastening am with a key of 17 and move the shock absorber together with the spring spacer to the side and up
Slightly lower the bridge, unloading the spring
With a 22 head, unscrew the two nuts of the spring fingers and remove the outer cheek of the earring
We unpin the nut of the axle of the front spring mounting with pliers
Use a 22 wrench to unscrew the nut and remove the washer
Using a mounting spatula, we remove the spring from the frame side member and remove it
Remove the inner washer from the front axle (the chamfer of the hole should be directed towards the frame)
Remove rubber bushings from the spring eye
We unscrew the bolts of the rear mounting bracket and remove the bracket together with the cheek of the earring and rubber bushings
We disassemble the rear spring mount and clean the spring from dirt
Using a chisel, we unbend the spring clamps
Clamp the spring in a vise and, holding the center bolt, unscrew its nut with a 17 wrench
We take out the bolt and push the vise jaws apart, disassemble the spring
Sheet bending radii
| Spring sheet number | Spring leaf inner radius, mm | |
|---|---|---|
| Front | Back | |
| 1 | 1506 | 1711 |
| 2 | 1449 | 1642 |
| 3 | 1377 | 1574 |
| 4 | 1306 | 1506 |
| 5 | 1236 | 1440 |
| 6 | 1167 | 1375 |
| 7 | 1100 | 1309 |
| 8 | 1100 | 1248 |
| 9 | - | 1100 |
Replace damaged sheets according to the table
Lubricate the leaf springs with graphite grease
We assemble the spring in a vice, centering the sheets with a screwdriver or a rod of a suitable diameter
Install the center bolt and tighten its nut
Bending the spring clamps with a hammer
When assembling and installing the spring, you need to pay attention to the difference in design:
- front spring eye;
- rear spring lug
If necessary, we replace the axis of the front spring mounting, for this:
- unscrew the nut ku axis with a key of 27, holding the axis with a key of 30
Remove the spring and flat washers
We knock out the axle with a hammer and take it out
Install the axle, bracket and spring in reverse order
When installing the axle, apply lubricant to its cone
Finally tighten the nuts of the axle, pins and stepladders of the spring in an equipped car standing on wheels. Otherwise
The service life of the rubber bushings will decrease and the stepladders may loosen.
Replacing the rubber buffer
We unscrew the two bolts securing the buffer to the frame side member with a 14 key and remove the buffer
Before installing a new buffer, lubricate the threads of the bolts
