Have a guge vibration while driving above 120km/hr speed, could you please suggest to solve this issue?

 

Welcome.

Whenever you ask a question Year (you did that), Miles and a description of any recent work done just before the symptoms you are concerned about started.

Without more info. suggestions would be the same as those you could Google. Bent rim, bad tire, wheel balance weights fallen off, bad U Joints, bad Front Drive Shaft CV joint, bad Half shaft.....

 

Thank you very much to Dear Doc Olds,

Due to the leaking engine oil, I changed the engine crank oil seal in march 2021 after changes only this happened.
