Guest Suprafly Posted November 5, 2009 Share Posted November 5, 2009 I'm getting a slight fient knocking from the front and rear, so I've put it down to worn droplinks (I think anyway). Now I have Tein HA coilovers fitted and my question is this.. Are the droplinks on the tein's the same size as stock? If they are I'll just order some up from Mister-T, but if they're not then they'll be a bit more of a pain to aquire. Anyone? Quote Link to comment Share on other sites More sharing options...
legendswraith Posted November 5, 2009 Share Posted November 5, 2009 Are you sure its the droplinks and that you haven't got pillowball mounts? The sphericals on the pillowballs are fairly cheap and nasty on the teins but they are replaceable. If you can find out the sizes of them i'm fairly sure there will be some nice sturdy aero grade ones kicking around somewhere Quote Link to comment Share on other sites More sharing options...
Ark Posted November 5, 2009 Share Posted November 5, 2009 Drop links are standard items regardless of the coilovers you have fitted. As with all moving parts in the suspension, it's worth replacing them every now and them, but as has already been mentioned, most coilovers knock and rattle because they don't have nice rubber cushions like the factory item. Doesn't necessarily mean they are pooched. Quote Link to comment Share on other sites More sharing options...
miko_supra Posted November 5, 2009 Share Posted November 5, 2009 Replace the drop links with standard toyota ones, I think they are about £30 each. I always found them to be worth changing. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted November 6, 2009 Share Posted November 6, 2009 Yeah I'm pretty sure it's the links, where they connect to the rollbar it's wet with as if the boot on the link joint has leaked, wear soon ensues. But I'll still check the topmounts just incase. I cant see the harm in changing the links anyway, as miko Supra says they're cheap. Ark... I've had various coilovers on various cars in the past, but not the supra, and some of these cars the Tein's came with shorter links than stock, this is why I wanted to check first. Thanks all.

Chris Wilson Posted November 6, 2009 Share Posted November 6, 2009 Just disconnect them both from the bar and see if the knocking stops. Simples.... Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted November 8, 2009 Share Posted November 8, 2009 I've ordered them now, and if it isn't them then at least I'll have new links fitted, and I don't fancy the prospect of testing the car without the rollbar links. Also the Tein HA's don't have pillowball topmounts, they're found on the superstreet type I believe. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted November 18, 2009 Share Posted November 18, 2009 (edited) Ok, the new droplinks are fitted, but the knocking is still there but it's quieter, so It looks like the links wern't the only parts worn here, this is starting to turn into a process by illimination thing. I'm now thinking lower arm ball joints, then failing that I'm going to replace all of the bushes. Any further ideas or causes is much appreciated fellars. *edit* - just to add, I'm not feeling any feedback through the steering wheel, so I've dismissed steering arm joints.

Is it just over road bumps, or does it ever happen on smooth surfaces but when pulling away from a standstill, or at low speed (sub 30mph) when you go from almost lock to lock.....large radius roundabouts? Subframe bolts and engine mounts are possible areas to eliminate from your enquiries Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted November 18, 2009 Share Posted November 18, 2009 It only knocks when driving over rough road surfaces like ripples, manhole covers, those painted lines you get before junctions, that sort of thing, never when driving over speed ramps or mounting curbs, or steering lock to lock, or pulling away, also it's front and rear. This is why I thought droplinks initially. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted November 28, 2009 Share Posted November 28, 2009 Ok today it went in for a good inspection and it was found that I had loads of play on the front and rear anti roll bars, the problem is the anti roll bar bushes, so I'm going to fit some poly bushes this week. Problem identified. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted December 5, 2009 Share Posted December 5, 2009 Famous last words.... Problem NOT identified! Replaced drop links and anti roll bar bushes and the knocking is still there, Today we had it on one of those shaking lifters to identify knocking causes, and none were found yet this annoying knocky rattle type noise still exists, I'm really baffled now. The following have been checked off the list so far: Bottom arm ball joints Upper arm ball joints Steering arm joints Drop links Anti roll bar bushes Wheel bearings Top mounts We are starting to suspect the bushes where the upper arms connect to the chassis now, this has indeed turned into an ilimination thing which could go on for a long time and seeing me replacing the whole running gear, it's so frustrating. I thought that shaker it was on today (which is designed to find faults) would point directly towards the problem, but found nothing wrong. D'oh!

Chris Wilson Posted December 5, 2009 Share Posted December 5, 2009 I just re read this saga. The most likely cause of a knock is the Teins themselves, internally, as the pistons either wear or come loose on the piston rod. Have you tried some proper dampers? The things are dreadful internally Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted December 5, 2009 Share Posted December 5, 2009 Right, is there a way of testing this theory? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted December 5, 2009 Share Posted December 5, 2009 Only by swapping out the dampers for some others. They might knock on a shock dyno, but it's not 100%, plus time on them is costly. Springs that have very closely wound coils at one end can knock, too. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted December 5, 2009 Share Posted December 5, 2009 Ok, you seem to know about tein's, now I have a question.... I had tein HA's on a Nissan Skyline a few years ago (same type as I have now on the supe) and when I jacked up the Skyline the wheels would lift with the car without dropping, with me? Now I have noticed that whenever I jack up the supe the wheels drop down, is this a sign? Quote Link to comment Share on other sites More sharing options...
Terminator Posted December 5, 2009 Share Posted December 5, 2009 When were the front and rear subframe bolts last checked for correct torque? Quote Link to comment Share on other sites More sharing options...

Now I have noticed that whenever I jack up the supe the wheels drop down, is this a sign? It doesn't surprise me, the Skyline ones obviously had no droop travel at all, which is just ludicrous on anything other than a full on, modern chassis, circuit race car. The fact the wheels drop a bit on the Supra just shows there's a BIT of droop in the suspension, but has sod all relevance as to whether they are knocking, or not. Just borrow some good stock dampers and see what happens re the noise. There's no other short cut really.. Quote Link to comment Share on other sites More sharing options...
Guest Suprafly Posted December 5, 2009 Share Posted December 5, 2009 Terminator, all I know is at the garage basically every bolt was checked and all are tight, but likely not to the correct torquage, but tight. Quote Link to comment Share on other sites More sharing options...

I'll change the suspension then, it's the only way to be sure I guess, I'm just confused as to why the shock test today didn't point to that, surely it would have been apparent?
