got this sound thats coming from the front right. it happens when i stop on an uphill so i can reverse to park

Its like got some play so when i brake it rocks back and makes the knock (mostly when im on an uphill so the car rolls back slightly)

best i can explain

some sort of bush must need replacing but im not too good on suspension issues so does anyone have any idea?

Could be your caster rods or if its aftermarket then it will be the pillow tension rods. Check also the tie rods.

I've got the same problem i'm pretty sure. Only does it once every time, right?

I think its the actual pads moving inside the caliper mounts; as theyre not a perfect fit, they tend to clack as they are moved when they contact the rotors. They caliper mounts should come factory with some kind of spring clips (i think) to prevent this (or at least to dampen it), but i think as mechanics/DIY'ers get lazy or careless, they dont replace them with the new pads.

only does it once, front right

and you could be right... only happened since i changed my pads but i dont see how they would be doing it

when i replaced my pads i put in the new pads, 2 shims and 1 smaller shim that goes on the corner of the pad, also put back the sliding bolts with the spring thing to keep them from sliding out

am i missing something??

Probably not, as most aftermarket pads are not a 'perfect' fit, they've got a couple of mm's of freeplay inside the caliper bracket. I'd say thats all it takes to make the sound.

ALSO to add something i just remembered... when i bought my car it has 4 new tyres which i assumed to be balance but most probably not aligned

anyhow... after 6 months or so i have MASSIVE wear on the inside front right tyre where incidently is where im getting the knock

what bushes/components would determine camber on the front?? im assuming its too much camber due to a worn bush or something

anyhow thanks so far

cheers

just to add, ordered some castor rod bushes, will replace them by monday/tuesday and will let u know how it goes

if that fails, will probably get new control arm bushes

Cool.. let me know how the castor rod bush replacement goes.. i'm looking at getting adjustabes in the next few weeks.

update, replaced the bushes on the castor rods which didnt look too bad but there were some crack going half way around them (which were a nismo item btw) with some d-project ebay jobbie ones

no knocking anymore, so far so good..

were easy to replace as all you had to do was jack the car up, undo 3 buts on each side

press out old ones bushes, press in new ones. Don't even bother if you don't have a press

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
