"Groaking" sound when going over hump

[EXO]

I am driving a Legacy 2.5 GT BL9.

 

Whenever I go over hump or roads whereby my front wheels will leave the ground (momentarily) I get this "Groaking" sound from the under carriage.

This sound is more pronounce when I first drive the car early in the morning (I assume when its cold, some rubber parts have not fully expanded).

 

Any idea what could be the issue?

Can be bushing? Morning stiffer then during day when driven a while feel less stiff?

Check your suspension mounting. It can be this problem surface

My front lower arm bushing (the one that is bigger) recently replaced.

Which bushing you referring to?

I replaced my van lower arm bushing recently and need to go for wheel alignment.

After the alignment, the boss took it for a test drive.

And says it's making gloaking noise and due to shock absorbers.

 

He's probably right.

I also have this issue but have yet to resolve it... Could it be the sway bar endlink worn out? Search for it in the net/youtube..

I personally experience this too and in my case, yes it is related to bushing.

i suspect subframe bushing? a number of bushings in undercarriage. i went to 1st auto semb to diagnose the croaking n found was subframe & sway bar bushings after replaced steering rack. for a few mths, car driving like new; now occasionally hear this sound early morning. maybe i also need to check front lower arm - can change bushing only or must change whole arm? price smthg like double if chg arm & bush ass'y.

i am having the same issue too on my back wheels when making turns and on uneven roads...

 

brought it back to AD and they said it is due to the stabilizer link faulty..

have them replaced and seem the prob is resolved...

 

but then, now my front wheels are "croaking" as well.

Hahahah... So many cars having this groaking sound......

 

Like TS case mine also have morning sickness... Having the groaking sound in the morning when going down mscp or over a hump... After warm up it seem the sound is gone....

 

My is 8 yes old cars... It seem all this ages of cars the sound is there.. Tough to trouble shoot... change 1 part Liao another sound come.. Change another 2nd part another 3rd sound come again... :(

 

Give up... As long no safety is comprises .. Will just bear w it....

90% of the time this noise is caused by the anti-roll bar bushing.

[Dream]

Just fixed mine... replace the mounting for the suspension and one linkage duno what is call... btw the sway bar endlink is ok... in case you are wondering how much... it is $226.

 

Now no more cloak cloak sound.

Probably not my shock absorbers, changed to a set of coil overs and the sound is still present.

My SUV had same noise when going over humps at low speed. Got both front lower links replaced and the croaking sound gone after that.

This is something new to me, subframe bushing. Will check it out. Thanks

bro, u read my feedback on 1st auto semb. They nvr chg any bushing. According to mech Meng, only removed bushings, sand away rust on bushing surface n frame bore, apply grease on bore, put back bushing, retighten. But I guess gd for few mths probably since initial sounds oredi present. I'll need to go back again.

 

Btw, if steer at an angle have a tok sound, what might be issue? Lower arm, shock mount, bump stop?
