littlebrownbike Posted July 27, 2009 Report Share Posted July 27, 2009 The reason that I ask this, is that I had my alignment checked less than 2,000 miles ago....and the results differed to that of the today. Let me explain. 77,700 miles, but with no correction - I left it how it is. 79,230 miles, still no changes to the car, but the alignment has some how fixed itself. The alignment was then fixed.

Tony Posted July 27, 2009 Report Share Posted July 27, 2009 You have to question the machines calibration?...... Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted July 27, 2009 Author Report Share Posted July 27, 2009 Lets assume its the same? Quote Link to comment Share on other sites More sharing options...
Tony Posted July 27, 2009 Report Share Posted July 27, 2009 Toe is the easiest angle to displace so it could have corrected it's position "by chance".... Other factors that will change the position is temperature, this will have a bearing on bushing compliance and damper compression. Quote Link to comment Share on other sites More sharing options...
NickT Posted July 28, 2009 Report Share Posted July 28, 2009 Doesn't mention which car it is. Could one where you need to add pre-load to the front and have a full fuel tank etc too. If it's the Ford Mondeo, aren't these renowned for front bush wear and other compliance problems? Quote Link to comment Share on other sites More sharing options...

If it's the Ford Mondeo, aren't these renowned for front bush wear and other compliance problems? I think it's on Garys mondeo, which is also a MK3 so wishbone bushes should be ok. It's the MK1 and 2 that has issues with wishbone bushes wearing as I would know! Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted July 28, 2009 Author Report Share Posted July 28, 2009 Hi, It is a mk3 mondeo, all the bushes were cheked while on the ramp...they are tight as a drum. In the space between those two alignment print outs, my new front offside tyre has worn badly on the inside. Quote Link to comment Share on other sites More sharing options...
CIH Posted July 28, 2009 Report Share Posted July 28, 2009 tyre wear seems to match the first print-out then....? Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted July 29, 2009 Author Report Share Posted July 29, 2009 tyre wear seems to match the first print-out then....? It would appear so, anyway I've just hit the biggest pothole I've ever hit, so now my alignment really will be knackered. Why do I bother!!!

littlebrownbike Posted September 7, 2009 Author Report Share Posted September 7, 2009 Lads, 2 questions. I got my alignment done 1000 miles ago, but have now had 2 new tyres fitted. Will my alignment be out again? If so, I have done 160 miles on my new tyres, will they have started to wear funny already? (as in getting it stuck in their memory). I really hope I dont have to spend another £70 on alignment!! (and yes I should have got them changed before the alignment...) Quote Link to comment Share on other sites More sharing options...
CIH Posted September 7, 2009 Report Share Posted September 7, 2009 tyres won't affect the geo specifically. I doubt 160 miles would be enough for a pattern to develop, unless it's really bad. I mean, undriveable bad. Quote Link to comment Share on other sites More sharing options...
Tony Posted September 7, 2009 Report Share Posted September 7, 2009 Normal driving, no huge potholes or excursions off a cliff the alignment should be fine..... Actual tyre condition at the time of an alignment makes no difference. Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted September 7, 2009 Author Report Share Posted September 7, 2009 Excellent, in that case my alignment should match the above picture, saying that I did hit a massive bump in the road!!! The operator told me a car needs aligning with every new set of tyres, this matches what I read in a fast ford / performance ford magazine when they did a feature on a certain company down south. But I take WIM's word for it! Quote Link to comment Share on other sites More sharing options...

But I take WIM's word for it! Their talking bollox.... It's wise to measure the chassis with each tyre change but not a requirement. The tyres condition during a calibration "cannot" influence the readings.. The tyre does "not" have the constructive energy to change the angles. The actual geometric angles is why the tyres are wearing "not" the other way around. Quote Link to comment Share on other sites More sharing options...
littlebrownbike Posted September 8, 2009 Author Report Share Posted September 8, 2009 Excellent thank you, the garage insisted my steering wheel won't be straight with new tyres. Quote Link to comment Share on other sites More sharing options...
Tony Posted September 8, 2009 Report Share Posted September 8, 2009 Excellent thank you, the garage insisted my steering wheel won't be straight with new tyres. Do you want me to speak to them because their obviously in need of education!! The actual chassis positions are a constant, the angles are not aware of the wheels or tyres so they cannot be influenced by new tyres, in fact when i calibrate a chassis i don't even need the wheel on the car!!
