2 Poor balance
3 PTO output shaft bearing or oil pump speed increase input shaft bearing wear is serious
4 Gimbal connection bolts loose
5 Front and rear universal joint installation direction is wrong
6 Cardan joint or telescopic spline worn badly

1 Straightening shaft
2 Do a dynamic balance test
3 Replace the corresponding bearing
4 fastening bolts
5 Adjust the orientation of the universal joint
6 Replace the new universal joint or replace the new one directly
