Kaamos Posted June 24, 2014 Share Posted June 24, 2014 Hi Since a couple of days I am having a whole bunch of weird noises coming from the back. As they all appeared together I made the assumption thay they are somehow related to one another. noise 1 appears : all the time, at each wheel spin description : high-pitched ticking sound occuring at each wheel spin (the faster the driving, the faster the ticking), forward and reverse, D or N (Auto gearbox). Seems to be there regardless to the speed except beyond a certain speed I can't hear it anymore because it's covered by engine and tire-roll. cause : comes from rear passenger wheel. Upon inspection I noticed that some "pin" of the brake-pad simply isn't there anymore (red-circled part in pic 1, taken from rear driver side). as a consequence, at each wheel spin, I see the part of the pad circled in green in pic 2 moving up and down at each TICK sound, showing the whole pad is a bit loose. Is it posible to order thoses pins alone or do I have to get new pads with all the fitting stuff ? my pads seem to have a fairly long amount of life still on them noise 2 appears : after highway ride, only when driving slow (about 20mph or less) description : lower-pitched and MUCH louder CLONK noise, still coming from the rear (passenger) area (?) causing light, still noticeabble vibration in the seat cause : perhaps a friction > heat > dilatation issue related to noise #1 ? sidenote : it seems weird to me but this sound sometimes happens only when turning right, sometimes only when turning left, and sometimes is constant when driving slow after a highway period..... then when I park and let the car cool down for a while the noise disappears. noise 3 I think this one has lesser links with previous issues but, still.... appears : after having driven for 0.5hr+ when heat builds up, when on throttle at given engine speeds-not always the same (disappears when off-throttle, disappears after cooling-down). description : lower-pitched machine-gun-like sound coming from the rear causing light, still noticeable vibration in the seat cause : perhaps a friction > heat > dilatation issue related to noise #1 ? and/or silentbloc problem as the exhaust seems to be a bit close to rear passenger triangle.... ? (rattleing noise while slow-driving on bumpy roads tend to make me think the exhaus is a bit loose as well) Thanks in advance for your help, I want my quiet supe back haha Quote Link to comment Share on other sites More sharing options...

David P Posted June 24, 2014 Share Posted June 24, 2014 Check the brake calliper isn't sticking? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 24, 2014 Share Posted June 24, 2014 My guess is seized caliper pistons or seized pads in the caliper. Quote Link to comment Share on other sites More sharing options...
Kaamos Posted June 30, 2014 Author Share Posted June 30, 2014 Thank you for your hints. In the meantime I made 2 small (not very exciting) videos to show the problem..... about noise #2, shooting them made me find out that if I don't use the brake (IE let the car slow down to stop in neutral or use handbrake), the loud cracking noise almost disappears.... here are the fantastic shaky movies : -low-speed city cruise, there's also a bit of noise #3 after the 1st turn in the 1st video https://vimeo.com/99535699 -some indoor parking stop-and-go's with windows donwn, no metal plates on the ground whatsoever, all you can hear comes from the car https://vimeo.com/99535702 This is a loud supra, but not the way you'd expect it to be :/ Quote Link to comment Share on other sites More sharing options...
