You may need engine or gearbox mounts?.

Sounds like something you should bring to the dealer

Faiez,

How many Km has the car done ? Has it had a hard life ? ie rough roads or driven without thought of a long life ?.

A good mechanic should be able to look at engine & gearbox mounts & say whether they have collapsed.

Shock absorbers should also be checked. Any oil leaks here where the seals have blown out?

Stay with it man & be persistent.

Inspect the car with the mechanic & ask him to show you the problem first hand.

Make him understand, NO FIX- NO MONEY.

All the very best of luck.

sounds like anti road bar bush or the drop links

also check the control arm if you can find a place that is good at the wheel alignment they can check it out when car is on ramp check your tires also
