Knocking Noise Front Left R33 Gtst

Hi all,

Having a little issue trying to find a small knock on my gtst.

It seems to be more prevalent when I am turning hard right and going over small bumps in the road.

It also does it goings straight.

I originally thought it was ball joints so they have been replaced but the noise is still there.

I have tried swaping my coilovers from left to right and it makes no difference, so I guess that rules them out.

Sway bar bushes look fine, ball joints brand new. no bushes look to be warn or sagging.

My next port of call is Sway Bar End links.

Let me know your thoughts.

Car: Ohlin Coils, stock everything else.

thanks

I had something similar after I put Cusco caster arms and some thick whiteline swaybars on.

The stock endlinks are a little weak and my whole swaybar had shifted a fraction over to one side, and as the suspension went up and down the caster arm was hitting the swaybar. The swaybars are the thickest non-adjustable ones that Whiteline make for the GTR, but they fit on my GTST.

I bought whiteline locking rings, but they didn't fit... in the end, I loosened the swaybar U-brackets a little, and crowbarred the swaybar back to the middle, tightened it all back up and now there is no more knocking.

Let us know if this helps!

even though you replaced the ball joints there is a stack of other bushes that could be worn and knocking and in my experience is the cause of knocking 95% of the time.

check on this diagram and you can see how many bushes may be the culprit...

      Slight brake pedal stutter after new pads

      Jack the back of the car up, pull that wheel off, pull that sensor out, and put a bore scope into the hole to inspect the outer casing, see if anything looks damaged before you pull the whole thing apart.

      Ergh... So I pulled the speed sensor out again and the tip was shiny so I think it's rubbing the bearing. The bearing contains the magnets for the speed sensor so I think when the first sensor broke it damaged the magnet ring on the bearing.  This is just a Google image, but there is a hole going to the bearing. So when the tip broke off the old sensor I'm guessing it fouled the bearing... As the magnet is only protected by a plastic cover it would be easy to damage it. So I guess I'm doing a bearing again.

      My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.

      Steps to DIY sanding car back ready for respray....

      Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.

      Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol
