Vibration during acceleration and braking

[YYC]

Hi what could possibly cause the vibration to Perdana V6 during acceleration and braking? The vibration is felt during mild acceleration as well as light braking only. No vibration is felt during hard driving and braking.
I have replaced the front brake set, both lower arms, as well as both driveshafts. It still happens. What else?

erm disc brake?

Not very sure....

But i think it could be the...

(1) Engine mountings need replacement

(2) Gearbox mounting need replacement....

No harm checking....

Unbalanced tyres or dented rims.

And rotors skimmed? Or replaced?

Already replaced another set, skimmed. No effect.

Yes I think there is at least one engine mounting is gone.

Unbalanced tyres or dented rims.

Maybe tyre balancing problem , damaged wheel... need to check.
Yes rotors, calipers and pads have been replaced. Rotors skimmed. Problem remains.

perhaps tie rod/ tie rod end woth checking also....

including alignment/toe setting

check your driveshaft, lower arms & engine mounting.

same with mine, while pick up from 70km/h my mech found that bearing at drive shaft is wrecked, changed the bearing not drive shaft problem solved

Just wanna update the progress.
I raised my car height by 20mm front and rear, the vibration has reduced in both circumstances. I think what my mech said was true, car height too low stressing some components like driveshaft causes some unpredictable problems like vibration etc.

means too lowered can cause vibration?hurm.....:stupid:...maybe....

Yes, I had that problem too when I lowered my front. After change back to original height no more problem. This is due to the angle of the drive shaft, when lowered....

Have u checked your suspension bushings? Vibrations may occur from worn out bushings too.
