Knocking Noises While Driving

[longiie]

Hello,

My car started to make knocking noises everytime I drive on a really bumpy road (hume highway for sydney people) and its really irritating.

I dont feel any handling issues and my strut looks fine not bent.

What is that annoying noise coming from?!@#

[chiksluvit]

Sway bar links or worn shock absorbers

[chiksluvit]

Or some loose nuts and bolts

[Duncan]

Well I think based on your description we can narrow it down to

loose wheel nuts

front lower outer ball joint

front lower inner ball joint

front upper arm outer bush

front upper arm inner bush

shock top mount

shock lower bush

caster rod bushes

front swaybar links

front swaybar mounting bushes

steering rack worn

steering column bush worn

front inner rack ends

front outer rack ends

front left inner cv

front left outer cv

front right inner cv

front right outer cv

front caliper bolts

engine mount

gearbox mount

tailshaft uni joint

tailshaft centre bearing

diff backlash

rear left inner cv

rear left outer cv

rear right inner cv

rear right outer cv

rear subframe bushes

rear LCA inner bushes

rear LCA ball joint

rear traction arm inner bush

rear traction arm outer bush

rear UCA inner bush

rear UCA outer bush

rear swaybar links

rear swaybar mounts

rear steering rack

rear inner rod ends

rear outer rod ends

rear outer steering ball joints

rear shock upper bush

rear shock lower bush

rear caliper bolts

or maybe it's in the interior. hard to tell exactly from the description

I only liked your pst Duncan because you went to so much effort to list every possible driveline part that could come loose, did it take you long?

[Duncan]

frankly, I'm worried I missed something and gave him a bum steer

[Sinista32]

maybe you could help with his other topic re Gearbox issue ......

[niZmO_Man]

Bushes flogged out, strut top loose, the springs themselves hitting something. Those are my guesses.

chiksluvit i have checked the nuts and bolts.

Duncan Holy cow. thanks for that list. ill slowly cross some off.

What Duncan did was list everything possible from the description you gave but if you give more detail it could be narrowed down without going through that whole list.

Does it do it when you accelerate on smooth road or brake hard on smooth road? Does it sound like its coming from a corner? Which corner? Is it a metal sound or a hollow sound(hollow sound as in knocking on your steering wheel vs tapping on a piece of metal). My car does something similar, in the rear corner. I have a leaky shock. Its like constant tapping in the rear right with every bump on the road.

Hey All,

Sorry for the late replies.

Ducan, thanks again for the list and it seems like it was the top mount and prob the outer ball joint as well.

Its all sweet now. Now im not paranoid of losing control at higher speeds, now for some normal driving speeds.
