Digsy Posted February 29, 2004 Share Posted February 29, 2004 I get this too. Seems to happen most when the road surface is a little bit wet. Feels like one wheel is slipping slightly? Link to comment Share on other sites More sharing options...
Steve Cargill Posted February 29, 2004 Share Posted February 29, 2004 Two possibilities. 1) Search for "i don't creak anymore" 2) LSD. Link to comment Share on other sites More sharing options...
Ian C Posted February 29, 2004 Share Posted February 29, 2004 Get yer subframe/suspension bolts tightened -Ian Link to comment Share on other sites More sharing options...
lust2luv Posted March 1, 2004 Share Posted March 1, 2004 I get this too, Toyota supposedly checked and tightened all my subframe bolts on a recent service (no I'm not convinced). When you say LSD, is that LSD performing normally, or LSD that is shagged? It's always made a slight clunk in that situation, but it seems worse of late.

It's always made a slight clunk in that situation, but it seems worse of late. I haven't got one so don't know exactly but remember it being discussed about the same time. Something to do with a tight turn and the wheels scrabbling as the diff does not allow enough difference in movement. Try the search. Link to comment Share on other sites More sharing options...
Digsy Posted March 1, 2004 Share Posted March 1, 2004 My noise comes from the front, so it aint my LSD. Link to comment Share on other sites More sharing options...
Guest Terry S Posted March 1, 2004 Share Posted March 1, 2004 Have the cars with this got lowered springs? Sometimes they move slightly. I have had it in the past with various cars. May also be duff ARB mounts. Link to comment Share on other sites More sharing options...

I could almost creak mine at will buy braking hard, flooring it - only upto 40ish then standing on the brakes and it would then clunk. This was in addition to the parking speed creaks.

Whitesupraboy2 Posted March 1, 2004 Share Posted March 1, 2004 I get this but not that bad...full lock and you try to move and feels like both wheels slip to the outside a little bit.but more of a jump sensation then a slip.....and its from the front as well... Had this on my old car...it turned out to be the steering rack was on its way out....hopefully not same on this car Link to comment Share on other sites More sharing options...
Digsy Posted March 1, 2004 Share Posted March 1, 2004 Originally posted by Steve Cargill 4WD Supra? No, it feels like the front wheels are slipping slightly. I can feel it through chassis. Only ever happens on full lock, when parking or reversing out of my driveway. Something I have noticed as well is that when manouvering on a smooth concrete surface (like a multi story carpark) the tyres squeak like hell. I've been told this can be down to the "Ackerman" angles not being quite right. This is the difference in angles that the front wheels turn through when cornering (because the outer wheel describes a larger diameter circle than the inner, so the outer doesn't have to turn quite to tightly). I was wondering whether it might be something to do with this? Link to comment Share on other sites More sharing options...
lust2luv Posted March 1, 2004 Share Posted March 1, 2004 I only really notice it backing out in a multistorey too with lots of lock. Link to comment Share on other sites More sharing options...
Bobbeh Posted March 1, 2004 Share Posted March 1, 2004 Me too, get it worse with the bigger wheels. Its a clunk, but its always done it on full lock when reversing. Link to comment Share on other sites More sharing options...
richy2jz-gte Posted March 2, 2004 Author Share Posted March 2, 2004 pphhheeewwwww its not just mine then, mines got standard wheels and suspension (at the mo) it does sound like it comes from the front of the car like a bush but ive checked everything its as tight as a ducks chuff.

Jez sutherland Posted March 2, 2004 Share Posted March 2, 2004 I get exactly the same problem - a big clunk when I reverse on full lock. Used to happen on a mates old car (Ford Capri - so a forerunner of the Supe then:p ) - turned out to be worn suspension top mounts. Don't know if it could be the same on the Supe though.

Ian C Posted March 2, 2004 Share Posted March 2, 2004 Still sounds like suspension bolts need tightening. Some of those suckers go up to 160+ft/lb so unless you've got a really beefy torque wrench and enough room under the car to swing it you can't check they are tight *enough*. I checked mine, the main bolt was less than 100ft/lb, I got it to about 130ft/lb with the space/leverage I could get on axle stands, and then snapped the extension bar I was using. The clunk was diminished but stilll there. Got the garage to do them all to the right figures and the clunk has gone and not returned. And I used to get it every time I used the car due to backing out down the driveway and turning right full lock. So it's worth a try... -Ian Link to comment Share on other sites More sharing options...
Bobbeh Posted March 2, 2004 Share Posted March 2, 2004 Originally posted by Jez sutherland Don't know if it could be the same on the Supe though. Capri Supra - are you on crack I might get my handy mechanic chappy to give it a once over and see what his opinion is. I've had it ever since I bought the car nearly 2 years ago. Thought it was normal. Link to comment Share on other sites More sharing options...
veilsideTT Posted March 2, 2004 Share Posted March 2, 2004 The clunk your all talking about sounds like the problem i have on my car. The noise i get is from my brakes. If i move forward slowly whilst braking and then reverse i get a clunk noise from the brakes. Same if i go reverse to forward. I was told by a few people that its my disks sliping slightly due to the fact that i dont have a little screw that goes through the disk to the hub to stop them doing this????? Awaits to be corrected:D Scott Link to comment Share on other sites More sharing options...
GetawayDriver Posted March 4, 2004 Share Posted March 4, 2004 i get this too, noise is defiatley from the front and comes from the side on the outside of the turn radius. more noticable in the wet with what feels like the tyre slipping, also worse on new tyres. my suspension is really low, just had the tracking done and it's still doing it. Could it be something to do with the geometry of the front suspension when on full lock in reverse that causes it? i think i will be giving the suspension/subframe bolts a tickle with the torque wrench.

Steve Cargill Posted March 4, 2004 Share Posted March 4, 2004 Got me thinking. I don't have the loose bolts at the moment but when on full lock in our rough yard it is very harsh when I go over anything rough when manevering . I'll pay more attention next time.
