Mj17 Posted June 9, 2009 Share Posted June 9, 2009 Hi,I'm running out of ideas so thought I'd ask if anyone had any suggestions.My car's on S alloys and was OK steering vibration wise until Sunday, when I took the front d/s wheel off to give it a good clean and keep corrosion/brake dust at bay.Since putting it back on I get a vibration at 70MPH that makes the steering wheel saw left/right, which is quite uncomfortable with a 60 mile motorway commute every day and the drive to Le Mans to look forward to.I've tried taking the wheel off and putting it back on after giving the hub a 1/4 turn - no difference.I've just had all 4 wheels balanced (at a specialist and not QuickFit - must be 6 weeks since I last had it done for much the same reason) - no difference.So...anyone got any thoughts what could be causing it that's triggered by just removing and refitting the wheel?Looking like a long (wet) drive to La Sarthe tomorrow at the moment :( Link to comment Share on other sites More sharing options...
Tim Bancroft Posted June 9, 2009 Share Posted June 9, 2009 Try another turn?Is it worse when you turn a corner at say 40mph? If so could be a track control arm ball joint? I am having big issues with this at pres. and I have been told that is the cause. Link to comment Share on other sites More sharing options...

Hard to identify with the suspension assembled.and/or Track Rod End Ball Joint, Wheel Bearing, Top Strut Thrust Washers, Top Strut rubber Mount, worn Shock Absorbers Link to comment Share on other sites More sharing options...
Mj17 Posted June 9, 2009 Author Share Posted June 9, 2009 Not saying this rules them out but...- Lower ball joints 12 months old (having had them fall apart on the way to last years Le Mans 24hr!).- Track rod ends ~24 months old.- Wheel bearing unknown but was vibration free until wheel off/on (and they end up off/on a lot :( )- Top strut thrust washers - none, roller tops fitted.- Top strut rubber mount - there is one?- Shocks ~9 months old.

Deleted User Posted June 9, 2009 Share Posted June 9, 2009 Have you accidentally trapped (and crushed) something between the faces of the hub and the wheel that means that the wheel is not seated properly on the hub. Something like that would cause the wheel to shimmy and feel out of balance. Link to comment Share on other sites More sharing options...
esxefi Posted June 9, 2009 Share Posted June 9, 2009 mj did you have the wheels balanced AFTER cleaning them?if not check you have not lost any of the balance weights,most wheels need weights inside and out.a sticky clean patch is a good clue.

Fuzzy Harris Posted June 9, 2009 Share Posted June 9, 2009 wasn`t the small centre disk and clips on the "S" wheel prone to throwing the wheels out if they weren`t fitted correctly, i`m sure somebody mentioned it before. Link to comment Share on other sites More sharing options...

Richard B Posted June 9, 2009 Share Posted June 9, 2009 Would'nt have thought so as it's weights further out from the centre of rotation that cause the balance problems. Link to comment Share on other sites More sharing options...

esxefi Posted June 10, 2009 Share Posted June 10, 2009 how about swapping front and rear wheel,the vibration may 'feel' different if it is the wheel at fault. Link to comment Share on other sites More sharing options...
Greeks Posted June 10, 2009 Share Posted June 10, 2009 I had chronic high speed steering wobble until I went to a 'good' tyre place ... they spent ages balancing and then fitting the worst of the bad S alloys to the rear. Now the front end all goes in the same direction at the same time ;) Link to comment Share on other sites More sharing options...
Mj17 Posted June 16, 2009 Author Share Posted June 16, 2009 Well just about had time to take one front wheel off, bash the centre disk forward with the butt of a hammer and put it on a 1/4 turn different.I don't know what did the trick and it's not perfect but was at least drivable and meant a trouble-free journey to Le Mans and back!
