Asklepios Posted April 28, 2002 Share Posted April 28, 2002 Grateful for comments on acceptable rear toe. Struggling to conceptualise ,but on 1990DD I suspect that will have to live with this manufacturing /fabrication error(3mm left). Who has grappled with this?

Rob Walker Posted April 28, 2002 Share Posted April 28, 2002 The rear should toe in 20 Minutes. Link to comment Share on other sites More sharing options...
felix.klauser Posted April 28, 2002 Share Posted April 28, 2002 If the toe is incorrect, check that nothing else is bent. If all is OK you could get the aluminum DeDion ear/plate machined to correct the toe. But only do that as a last resort when all else appears to be correct.

Asklepios Posted April 28, 2002 Author Share Posted April 28, 2002 Thanks chaps. Does the DD ear usually determine the toe as well as the camber, or is this a fix to "correct" another out of true? If not, then how is the toe normally set. From your experience is this deviation from spec unusual? Link to comment Share on other sites More sharing options...
felix.klauser Posted April 28, 2002 Share Posted April 28, 2002 You're measuring 3mm per wheel or 3mm overall? What's your method of measurement? If my maths is correct 3mm of toe on one side of the car with a 21.5 inch diameter wheel equals 0.64451055 degrees. This is 38 minutes of toe. If the factory spec is 20 minutes then you've twice the recommended toe. Machining the aluminium ear is a way to compensate for another fault. What's the wear of the tyre like.

sjwb Posted April 28, 2002 Share Posted April 28, 2002 I think wheel / hub run-out will take care of the other 18 minutes!!!!!! Steve B Link to comment Share on other sites More sharing options...

Asklepios Posted April 28, 2002 Author Share Posted April 28, 2002 Felix, Thanks for your advice. On 4 wheel laser measuring device,nearside +3.1mm ,o/side 0.1mm. Tyre wear not signif.dif.. Thus if Rob is correct ,the o/side is closer to spec. ,but n/side is toeing out. I suppose what you are saying is not to get too precious about these small variarions and sj`s observations on the other system errors is well taken. So my question again,does DD determine toe ?

felix.klauser Posted April 29, 2002 Share Posted April 29, 2002 Yes, the DeDion tube determines the toe. There is no adjustment per se; what you get is what you're stuck with. Try swapping radius arms from left to right and see if that changes it. I think the length of the radius arms is a major factor in determining toe after the trueness of the DD tube.
