What is wrong ?

[Vextan]

If car wobbles left to right vigorously when go over hump, what could be wrong ? Gurus, pls advice, thx.

[So_nice]

suspension problem? i think like quite normal leh. especially for big humps.

 

u might wanna check for leaks or uneven height of ur ride. or maybe tyre not enough pressure. :)

[SimonTan]

I think its unbalanced could be due to the driver is too heavy.

 

Time to change the damper I guess, since it cannot control the bounce and rebound of the spring.

try humping.....er bumping your car and if it stops immediately means ok...if it oscillates and takes time, then get a mech to check your suspension

if i'm not mistaken, are u referring to the steering wheel shuddering left and right when u go up the hump? If yes, then i'm guessing that u have lowered ur ride wif aftermarket coilovers. Not enuff suspension travel may cause such issues as it affects the suspension gemetery of the roll centre of the car, causing bump steer. A set of roll centre adjusters might help. Tie rods ends have roll centre adjuster properties too, u can check out moonface japan or ikeya formula.

before u commit on RCA, what suspension/coilover are u on? if u set it too hard...this might happen...

 

I had RCA on it.. but it doesnt works on your scenario...

[SimonTan]

Tried that for my car last time, I can't even push it down. Maybe I 'm too light.

Have your suspension & steering components checked by a reliable ws. maybe u sud try a different ws that changed your shocks recently.

 

Another cause cud b worn ball joints.
