"Groaking" sound when going over hump

[Yymail22]

Hi. Here's an update on what was done to the groaking noise.

 

Went to a workshop at Ubi. Described the symptoms to the boss. He tested drove the car, tested on undulating roads as the noise was most pronounced on such surface. He deduced that it was the steering rack. To replace with original, it would cost $600. It was $400 for canabolised part from scrapped cars.

 

At another workshop nearby for second opinion, the mechanic jacked up the car, went underneath to check. He then lowered it, went below the steering column in the driver's seat. He took a socket spanner to adjust something. He took a ride in the area. His conclusion was a coupling at the steering giving fault. The cost to replace was $200+. His boss subsequently showed up. Understood and tested drove with me. He thought that I had over inflated the tyre pressure. Instead of 32psi, he recommended less so there is more surface area contact and less vibration to the car.

 

I left without replacing any part.

 

As I drove back home, I noticed the noise was absent. On the next day when the tyres were cold, I lowered the tyre pressure to 29psi. It has been 5 days now. The noise is gone. I think it could be a loose part or something that required tightening. I also enjoy my ride more as there is more grip on the road though I have yet to check the petrol consumption.

May I check for those with faulty lower arms, do you feel like the car will sometimes will lean abit to the left/right?

bro, mine single tok nia. Recently weather hot til no tok liao.

 

Most likely it is sway bar link or bushing. I have been trying to find what make this "tok tok" for quite some time and recently i found that there is play around the bar when i move it, replace the rubber bushing and no more "tok tok" sound. Bushing cheap, cost me $30+ for a set. I also grease the rubber bushing before fit in, now super quiet.

 

something like that.

bro, i've changed shocks, mounting, bump stops n above bushings n links in contact w sway bar in red 2 yrs back, but noise still persist till i replaced left cv joint. now still some "groaking" sound like low / muffled metal grinding tone. suspect n may try changing lower ball joint though couldn't observe any cracks on lower arm bushing n ball joint.

Mine is the sway bar D bushing, ask your mechanic to check if there's play, mine is only slight play but that the cause of the sound.

tks bro, mine was lubricated & changed 2 yrs back, incl stabilizer link, but still not eliminate sound. so i concluded such sounds may be quite difficult to detect, n this not helped by ws here not willing to do proper diagnose using proper tools like veh stethoscope. so on our part as car owner, need to brush up our mech knowledge.

I know, i been trying to trace the sound for mths and finally i found some slight play on the bush while checking the sway bar link. i suspect it's the link but end up it's the bush.

Surprised to see so many people having the same problem. I have sent my car to 3 different WS to trace the problem. I told them about the "morning sickness". All did visual check and said no problem. But the sound keeps coming back. Mentioned to mechanic when changing starter motor but also cannot find problem... Really fustrating.

 

Will go bring it to check for the stabilizer link and sway bar.
