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?!@#

front upper arm outer bush

front upper arm inner bush

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

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

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.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
