Replace rubber bushings when worn
- 1. Place the vehicle on a lift or a pit.
- 2. Clean the attachment points of the levers from dirt.
- 3. Gears with chipped, chipped or broken teeth must be replaced.
- 4. Loosen the wheel fixing bolts.
- 5. If the vehicle is in a ditch, apply the parking brake, chock the rear wheels, raise the front of the vehicle and place it on jack stands.
Install a jack (preferably hydraulic) under the spring cup and, lifting the cup with it, load the spring.
- 6. If the car is mounted on a lift, first remove the wheel, and then place a stable support under the spring cup and, carefully lowering the car, load the spring.
7. Unscrew the fastening nut 1, remove the pin 2 and disconnect the upper levers 3 from the rack. Unscrew bolt 4 on both sides and remove support 5 with buffer.
8. Unscrew the nut 1 securing the lever on the axle, remove the spring washer 2 and washer 3 from the axle.
Remove lever 5 from axle 4.
To facilitate the removal of the lever from the axle, it is necessary to moisten the axle and the bushing abundantly with brake fluid, while shaking the lever in a vertical plane so that the liquid passes between the axle and the bushing.
If even then it is not possible to remove the lever from the axle, it is necessary to remove the axle with the assembled arms by unscrewing two bolts 6 and two nuts 7 securing the axle to the front suspension beam and removing the adjusting plates 8 located between the beam and the lever axle.
- 9. Press rubber bushing 2 out of lever 1. If the levers were removed with the axle assembly, first press the axle out of the bushing by holding the lever in a vice.
When the axle is pressed out, it is possible that the spacer sleeve 3 will remain on the axle. In this case, the spacer must be removed from the axle by sawing it or carefully cutting it with a chisel.
- 10. Thoroughly clean the lever eye from dirt and possible remnants of the old bushing.
- 11. Moisten a new rubber bushing with unleaded gasoline and insert the spacer bushing into it.
Press the rubber bushing assembly with the spacer into the eye of the lever using a mandrel.
- 12. Inspect the seat of the lever on the axle, if necessary, clean the surface with fine sandpaper.
- 13. Install the assembled lever on the axle.
- 14. Further installation work is carried out in the reverse order of disassembly. In this case, the head of the finger should be directed forward along the course of the car.
Let's take a closer look:
Jack up the car and remove the front wheel.
We install a support under the spring cup and lower the car, compressing the spring. The upper rubber buffer should move away from the stop.
Turn off the nut with a 22 head
We knock out the upper pin of the rack with a copper hammer.
Using a 12 key, we unscrew the bolt securing the upper buffer to the lever and remove the buffer.
We take out the rubber sealing rings of the threaded hinges.
Turn off the nut with a 24 head,
remove the washer and remove the front upper arm from the axle.
Remove the second washer from the axle.
The steering mechanism interferes with the dismantling of the second upper arm on the left side of the car, so we remove it together with the axis of the upper arms.
With a vise, through the mandrel, we squeeze the spacer sleeve out of the rubber bushing.
Then we squeeze the rubber bushing out of the lever in the same way.
Wet the new bushing with gasoline or WD-40 liquid and use a blunt flat screwdriver to fill its edge into the lever hole.
Having pressed by hand, we finally press the rubber bushing into the lever.
We also press in the spacer sleeve.
This is easier to do by inserting a slightly larger steel ball into the hole in front of the spacer.
Install the lever in reverse order.
It should be borne in mind that the final tightening of the threaded connections for fastening the levers should be carried out only on the suspension, which is in a loaded state.
Tightening torques: pin nut - 120 - 200 Nm (12.0 - 20.0 kgm), axle nuts - 70 - 100 Nm (7.0 - 10.0 kgm), bolts and nuts for fastening the axis of the upper levers - 44-56 Nm (4.4-5.6 kgm).
Check the alignment of the front wheels. (Descent collapse GAZ-3110)
