Dude, we car enthusiasts are all the same. I am equally difficult when it comes to my own car. So no need for apologies.
As for the PU bushes, I had some PU bushes in my old car but I didn't have noise like you. The noise was caused by other parts of the car moving/rattling more because of the bush. Having said that I've been in the Superpro PU test car that had everything swapped out. Full PU. The ride was pretty awesome and the only thing was the engine vibration was a bit too much because of the solid mounts causing rattling and all. But I don't think your car is having these issues. Probably metal to metal from the billet arms. Try greasing it yourself perhaps?
Sorry for the late reply. A few issues have come up since then. I realised no amount of tightening will rectify the noise, as it didn't come from the bolts not been tight enough. In fact i see the workshop use pneumatic air gun to tighten the bolts up, which cause massive scratches the arms, and also damaging the bolt and nut treads. SIGH. The noises did not cease. in fact they became worse. The reason, (or part of the reason) was some freeplay where the part the coilcover lower mount is bolted to the arm. Only the left hand side. If i wiggle the shocker body, it will hit the arm. thats what causing the noise. Funny i dun have that issue wif the original arms. I have since inserted a small washing to lessen the free play.
To be frank the noise is coming back, this time wif a vengeance. its getting worse, and while i can accept operational noise, i cannot stand knocking. its telling me its metal and metal which... isnt supposed to happen? Nevertheless I have rear superpro bushings and i decided to press them into my rear lower arms... So i got a very prominent workshop in JB today to help me press the arms.
I am from SG and as i didnt drive today i thought they would help me wif the press and i can bring the arms home and install them at another workshop when i have time.
The main point being i wanted to try isolating the noise. If it still have the same sounds then it must be my coilovers, If not then its the arms...
Alas.
Sometimes doesnt mean well known workshop will do a good job. This is what happens when you work with no heart. Now i have to go back to get them to push them out and repress in for me.
Nin na ma eh, best part. I dunno which side is pressed right, which side is pressed wrong now. apparently, 1 side either of the front or rear of both arms, should have a shorter/longer exposed area of bush. I hope i am making sense of what i am saying.
I am also wondering if pushing these bushes and their relevant steel parts out and pressing them in again will spoil them or not. If they become more loose, seriously whats the farking point....
