wim is not finite to say the least.

Maybe not, but you'll know more on the subject than I ever will

Seriously, I had no idea before joining this forum that geometry was such an involving subject (why would I?) I find it rather disconcerting that if my geometry ever needs attention, I will HAVE to drive a long way to have it done correctly. Omega owners are like that

I too was a bit naive on geometry, and kept taking car to local tyre place to overcome wandering/pulling/uneven wear.

Then I found WIM's website.  Its a complex read (well I thought it was), but its a complex subject, far more complex than I ever imagined...  ...there are still parts I do not fully understand, which is in itself frustrating.

There is no need to understand it in it's entirety... The wim site is divided between basic and theoretical allowing the adventurous to delve as deep as necessary.....

In truth Geometry is a mere scratch in the overall package of chassis dynamics. Expanding on theoretical dynamics would serve little value to this club so please understand the overall picture is much wider than the wim frame. although it is interesting

Sorry I haven't posted for a few day been away at work..

I had the wishbones changed in july this year after failing the MOT due to worn bushes, I then changed the rear shocks in september and at this point I decided that because I had work carried out on the suspension it would be best it I got the geometry adjusted. Its only been since the geometry was adjusted the problems have become more noticable, being a logical guy I put it down to the steering being much lighter as it used to be very heavy before. Although the geometry is now true, I suspect some sort of failure in a suspension component but the question is which part? I can't find and problem with the wishbones (both bushes both sides and balljoint look fine) and steering idler looks okay, my suspicion is the springs as the car has now done almost 104000 miles and 100000 miles seems to be about the correct time for failure. i'm going to do the tests that tony suggested weather permitting. When I describe the pull to the left it seems to be more noticable when braking its not so much of a pull but its as if its easier to steer to the left, not sure if this is a fault but it could be related to the camber on the road. It just doesn't seem right.

If it doesn't FEEL right, then it probably isn't.

My experience - The front tyres were a missmatched pair with the offside one worn on inside and outside edges.
 Before fitting new tyres, I had a full alignment done by a friend who works at a Subaru dealer. With their 4 wheel drive, they must be even more sensitive to mis-alignment than an Omega.
 It felt better to start with but slowly got more ' Bumpsteery ' on country lanes over the following weeks. Then I had a new pair of tyres fitted (Falken) and the car is fine now.

That's interesting. I've just swapped my front and rear tyres and have picked up a wobble and vibration.

I think I'll start with a wheel balance. I can't see any play in any suspension or steering parts.
