kawan2 tlg............
my car is a 4 door e30 with m40 engine. the problem is...bila tekan pedal minyak utk laju je msti gegar...gegar kuat..
what causes this? drivetrain? suspension? tlgla daku......

do you feel the vibration even when you rev at idle?

tayar allignment ?

Probably cause
please check in stages.

0. BAD balancing (when reached certain speed)
1. Center bearing (when car is moving and acceleration)
2. Long Shaft (gearbox to rear axle - stump sound and vibrate)
3. Dry Shaft (rear axle to rear wheel)
4. Gearbox mounting
5. Lower arm (this sometime vibrate when brake)
6. Disc brake wobble (this happen while braking)

i suspect the centre shaft bearing or the guibo since he said when accelerating..hmmm...must check

not happening when revving in idle.......

VIBRATION DAMPER ON YOUR DRIVESHAFT...RM 4++

03 TORSIONAL VIBRATION ABSORBER 1 2611143425

dont forget to check long shaft coupling

thanks bro.... more specific details..
the car start vibrating on the rear left side on and occurs on the 4th gear and above when the rpm reaches 2k and above with speed 60km/h and above

SAME THING HAPPENED TO MINE.the damper comes loose as you speed up and has the expansion effect hence the vibration and gravity pull effects the rubber as you go into a turn....much like tying a ball with a string onto your driveshavt and driving fast.....go under your car and check nn see if ithe rubber thiny has come lose as in the realoem part no 3 above

thanks bro...........might bring my car to a wheel shop..
