dhague Posted October 18, 2001 Share Posted October 18, 2001 For some time now, I've noticed an increasing tendency for tyre squeal coming from the outer-rear when turning right - initially when driving hard around roundabouts, but now on more and more 'normal' right hand bends. Does anyone have a clue what might be causing this? I don't think the tyre's rubbing against anything (since there are no scrub marks which would give it away). Could it be a damper? I had to replace the front dampers earlier in the year (oil was seeping from the left-hand one, i.e. the same side which is squealing), and I'm wondering if hard cornering on roundabouts together with some limited trackday abuse (including 2 or 3 spins & kerb-hops) might have damaged it. Or is it just road-camber and Avon ZZ1s? - Darren. Link to comment Share on other sites More sharing options...
philwaters Posted October 19, 2001 Share Posted October 19, 2001 Hi, I also have a slight squeal when taking r/abouts a bit quick, although mostly the tight ones. I don't think mine is caused by the tires though, to me it sounds more mechanical, but can find nothing wrong. I have pretty new dampers so I doubt it is them and have given up trying to find it. I will take a few r/abouts quick when in Spain next year to see if it does it the other way too wink.gif I am running a live axle, and suspect it could be something in a bearing somewhere.

Miraz Posted October 19, 2001 Share Posted October 19, 2001 Does it still happen without your better half in the car? Just checking.... Miraz Link to comment Share on other sites More sharing options...
dhague Posted October 19, 2001 Author Share Posted October 19, 2001 It definitely happens more with Alina on board - and she weighs a few kilos more than I do. Also, it's definitely tyre squeal, not bearings. The car has a deDion rear end. I'm tempted to swap the dampers over from left to right on the rear - this should tell me if they are the problem. Are there any 'gotchas' I need to know about when doing this? - Darren Link to comment Share on other sites More sharing options...
Alex Wong1697456877 Posted October 19, 2001 Share Posted October 19, 2001 Check you A-frame, especially at the rear joints. I had a bush fail here (still waiting for Caterham to send new ones......). This resulted in the rear axle being able to move from side to side. Link to comment Share on other sites More sharing options...
Tony Martyr Posted October 19, 2001 Share Posted October 19, 2001 I had exactly the same problem on a track during the Le Sept trip. As Roger Swift was running the same tyres and is expert in all matters relating to driving fast I asked why he thought I was getting tyre squeel on right handers and not on left handers. His answer was that I was not driving fast enough round left handers. Who needs advice when given wisdom instead? Link to comment Share on other sites More sharing options...
Andrew Walker Posted October 19, 2001 Share Posted October 19, 2001 This might sound strange but (depending which engine you have) it could actually be the alternator fan blades just contacting the engine mount as the engine leans over to the left on the bend.

Rob Walker Posted October 19, 2001 Share Posted October 19, 2001 If you have a rear ARB and its set on the softest setting the drop link could be rubbing on the inside edge of the rear tyre . As this drop link is very smooth it may not have left much of a witness mark Link to comment Share on other sites More sharing options...
millsn Posted October 22, 2001 Share Posted October 22, 2001 It would depend on how loud your squeal is but if your tracking is out your tyres can squeal (more like squeak really though) in certain conditions (esp multi storeys) Nigel Mills - 2.0 Zetec carbs Link to comment Share on other sites More sharing options...
Graham Perry Posted October 23, 2001 Share Posted October 23, 2001 Mine occasionally does this but only since I fitted the AP Suretrack. Have tracked it and all bushes are fine, so its a mystery, but it is definately the tyres. Link to comment Share on other sites More sharing options...
dhague Posted October 23, 2001 Author Share Posted October 23, 2001 Thanks all - I do have an LSD fitted, and definitely get it in multi-storeys quite a lot. I'll get the tracking checked, but it could well be the limited slip, as suggested. Must try and find some tight left-handers to play with... smile.gif Cheers, Darren.

Delberts Wallet Posted October 23, 2001 Share Posted October 23, 2001 Darren, you could save yourself some time looking for left hand corners and use the same right handers but in the different direction. Thus having a constant to meassure by wink.gif Gareth Edited by - Gareth Harrold on 23 Oct 2001 14:11:42 Link to comment Share on other sites More sharing options...
Red SLR Posted October 23, 2001 Share Posted October 23, 2001 Not read all of this so dont know if it has been mentioned... My SL on 13s rubs the front wheels on the wing mounts.... have you checked this? When stopped there is about 3mm of clearence but you can see the "shine" on the edges of the tyres.

dhague Posted October 29, 2001 Author Share Posted October 29, 2001 I think I've worked out why there is squeal on right handers - something I remember from biking days, when the thread was 'why can I go faster round left-handers?'. The answer, my friends, is road camber. Since we drive on the left, whenever we go right we are travelling on adverse camber. When turning left, the camber helps us. Hence, for the same speed (near to the traction limit), the limit is exceeded going right (hence the squeal) and not when going left. If I'm right, I shouldn't have the same effect on a track, since clipping the apex means that the camber is always positive. Similarly, the reverse phenomenon should be observed on the continent. I shall report on both og these when I get the opportunity. Cheers, Darren. Link to comment Share on other sites More sharing options...
