Dear BLM owners,

I've got myself a BLM for approx. 2 years soon already .. and now I noticed that there are sounds from the driving shaft whenever I pass through road bumps (when the car starts shaking while passing) and the engine seems to be another issue as well.

The sounds of like something loosen when you left go off the acceleration pedal or while you are stepping on it.

Does anyone here face such problems before ? .. Any solution to this ?

I ask some of the mechanic and they mentioned about that.
But I haven't asked them to fix anything yet. Thats why i am here ..

Its like when you are driving down / up the parking lots (ie shopping malls), the road will be bumpy right ? Then the sound will be produced when your car is shaking.
And the engine part will be during acceleration or releasing the gas pedal, the sound will be there like loosen screws. Got no idea what had happened ..
It used to be one of the common problem I encountered with my past experience when driving Proton Wira.


My came from both sides as long as it goes pass those bumpy roads. Some mechanic said its normal to have such problem dont need to change any parts, some said driving shaft, some said engine mounting structure ..

Really got confused with different feedbacks.

Last time I did mention to the mechanics over at the 3S Centre, Damansara about the noise issue. After checking they said is nothing wrong. But after service the sound is still there .. and worse part is they peel off the cover of the steering wheel and its loosen after that. 2 sounds coming at the same time in the end ..

Yea ! Its from the outside like metal shaking sound .. Abs ? Does that means I need to change a new one ?

Stepping the gas pedal and brake at the same time ? But the sound seems like coming from the engine itself rather than the wheels. What do you think ?

Thanks for the tip,MR_alien.
Really appreciate it very much. If that's the case I guess I won't be changing anything at the moment till it reaches the stage of necessity. I will give a try on the method u mentioned for the brake pedal vibration issue and lets see how it goes.

Thank you.

Most of the time, the roads that I travel is among the highway type and of coz roads with yellow bumps whether its my office building or my condo area.
At the moment the sounds of the abs is slowly getting louder ..

Hmm .. I see. I guess I still can take it on this sound issue. SC I dont really trust them sometimes when they simply just check your car's condition and charged us at a high price while the problem is still unsolved.
Sigh ..

Almost hitting 2 years already. 15K mileage service is done .. at the moment nearly 40K mileage ++ ..

I mean I've done with the final service by the SC which is free for the first 3 times. After that I went to workshops outside instead of the SC already.

@MR_alien
I've tried using the way you mentioned earlier by sticking my feet to the brake pedal to make sure its not vibrating but the sounds is still there .. from the engine compartment. Any idea ?

Are you sure its the brake pad, Bro .. ?
Its when I accelerate or letting go the pedal .. the sound comes from the engine as if there is something loosen like a screw hitting the walls like that.

I've done everything through the phone and of coz MyEG as well. It took me approx RM1.3K ++ if I am not mistaken.

Dear Bro, my answers are as stated below :-

1) Well, you could try recording the sound and posting it here?
• Its abit difficult to record the sound as it comes from the engine and it won't be really that loud if I wind down the window as well.

2) Are there any abnormal vibrations or not?
• At the moment there wasn't any abnormal vibrations - just that besides this issue, is my car abs that making sound whenever going pass the road bumps doesn't matter at fast or slow pace.

3) The sound only happens when you press the accelerator and let go the accelerator?
• Yes, at the moment it will happen either this 2 event take place.

4) It's a sharp loose metal sound? Like nail fall on floor?
• Its like a loosen screw hitting within the four walls between it. There is other sound that shakes when I drive along the bumpy roads (ie not smooth ones) - due to the new door that had been replaced after accident.

Thanks Bro.

I have tried the ways you mentioned earlier on try to balance the brake pedal to avoid the annoying sound but it seems to be not working. Guess its time to check out with the mechanic again ? .. As the sound is getting louder and more obvious.

Alright. Guess I will make it on the next service appointment with them. Just hope that it will not cost me a bomb to change any of the car compartments.

My car engine sounds like that .. what would be the major problem ?

What is IAFM ? .. does that means I will have to change any parts in the engine compartment ?

This kinda of sound have been started since the 1st year when I've got the car. Approx half year's later and I thought its very common also.

You mean if my car hits about 80KM/H .. but default there will be airplane sound ?
Mine I guess no airplane sound but the engine makes heavier noise when accelerating till 100KM/H
They didn't seem to have checked or fixed it for me either after 3 times service @ SC.

Alright. I will give it a try later today. Thanks for the tip.
