Usually vibration on ZIL-5301 is felt most at a speed of 60-70 km/h
If vibration occurs when driving ZIL-5301:
First of all, you need to check the wheel mounts and the condition of the rubber.
When a wheel loosens, vibration immediately occurs. Vibration can also occur due to poor tire condition.
It is imperative to install tires of the same height for paired wheels.
Tyres that specifically say "Bull" have proven themselves well.
Next, look at the condition of the driveshaft.
Inspect the suspension bearing and crosspieces.
Inspect the driveshaft mount itself.
Check the gearbox mount.
The gearbox should be screwed on well.
After driving on a bad road, you need to check the tightening of the rear axle shafts. You should also definitely check the tightening of the front caliper bracket.
If the previous steps did not eliminate the vibration:
Inspect the tightening of the wheel bearings. Perhaps, some wheel hub is loosening and vibration is occurring.
Check the play in the cardan-gearbox joint.
Vibration can also occur due to the destruction of the differential and wear of the gear pair of the gearbox. (On this topic, you need to look at the articles on repairing the rear axle gearbox).
Open the clutch guard and check the tightening of the clutch basket and the general condition of the clutch mechanism.
Basically, these are all the points for identifying the causes of vibration.
Minor vibration can occur due to wheel imbalance and imbalance of the cardan and flywheel.
