my car steering wheel vibrates when the car is going at 100++ kmh, i asked around and was told to do high speed balancing

but after searching around, many ppl said that it can damage the gearbox, especially on auto cars

so i want to ask is it really going to damage the gearbox?

are there any good on wheel balancing shops can recommend?

https://forum.lowyat.net/topic/2240033/all, this thread many years ago got mention it can damage gearbox
the transmision is in neutral? they got the machine to spin the wheels up to 100++ kmh? i thought they will step the pedal and make it run to 100++ kmh?

how is on wheel balancing being done actually? they jack up the whole car and there is a balancing machine to spin the wheels on car?

Never know got on wheel balancing..never done b4. If my car, accord do this, it will become smoother 🤔🤔?.

All of my car just do normal balancing. Never know got high speed balancing. Lol.
