Mine pulled quite significantly to the left,new tie rod ends and the subsequent re-alignment made no difference,until I changed the front tyres 600 miles ago...then it spent a couple of weeks drifting to the right 
It has now settled down,and tracks straight,suggesting, in my case at least, it was tyre related. "Better to remain silent and be thought a fool,than to speak out and remove all doubt" ?.....what rubbish...

Hi
This is a long shot but is the garage actually adjusting the tracking, this is just a thought but when I replaced the front arms on mine I had to use oxyacetlene to heat the bolts to release them before replacing them with new ones so wondered how on earth they managed to adjust anything if the bolts were totally seized its not like you can heat them without melting the bushes which would then need replaced.
Do the dealers have an alignment machine that gives a print out before and after Ive never been offered this so was just curious, as most other alignment companies give you this so you can actually see that they have done something
cheers

They have a machine that shows before and after. Everytime recently it is done it is within spec, but whether or not they look at it and can see whether or not it can be adjusted is another matter.

check out this PDF for possible reasons of error....assuming you haven't bent the chassis
http://www.disco3.co.uk/gallery/albums/use...5B1%5D.pdf
also check camber not just toe front and back
If the Steering Axis Inclination (SAI) is different from side to side, it will cause a pull at very slow speeds. SAI is a nonadjustable angle, it is used with camber and the included angle to diagnose bent spindles, struts and mislocated crossmembers. i.e when blasting around Morroco...  It is better to have and not need it then need and not have it.

Thanks for that. I'm going to speak to another company who are up the road frmo where I work and they do four wheel alignment and will see if they can put it in tight tolerance mode if they can check and adjust it or if they have ever done one up there. I spoke to my local dealer last night and they are going to try and find a D3 that they have that I can try to see if that pulls to the left as well. If they all do then I will have to live with it, but it never did it at the start.
I would be surprised if I have bent the chassis as it has never been in an accident whilst I have owned it nor has it been offroad and it would have to be an almighty great big pot hole to bend a chassis and be taken at speed.

If the steering wheel isn't straight, then it needs to be adjusted, via the track rods until straight. most 4 wheel alignement machines set the wheel in straight ahead position & then you adjust the tracking each side to get correct.
The front Castor angle has a big impact on the vehicle pulling, as does the difference side to side of camber etc.
The front lower wishbone bushes need to be in good shape, as this can cause the wheel to go back on one side slightly causing pulling.
What mileage have you done & what suspension work have you had done up til now?
If you have a printout of the readings of the four wheel alignement that might be helpful, although if the steering wheel isn't straight it means the wheel alignment needs doing corrctly again.
Regards
Steve

Thanks for that. As far as I am aware some anti-roll bar links and nothing else. The first alignment was done at my service when I had four tyres as they were wearing abdly and it is ever since then, but have had a following three wheel alignments after that as well to try and cure the problem.

I'm going to swap the wheels side to side and see if that makes a difference before I do anything else with the car. Tyres can do strange things, and in a way it would be nice if it was something simple like this that could be solved pretty easily.

Tyre wear will cause a pull, but usually because they have worn unevenly.
worth swapping side to side as you say

I certainly hope that if I swap them side to side that I don't suddenly pull to the right as then I will need yet another set of new tyres  Alex

I think I remember, when I had mine tracked on the Hunter kit, the guy said that the D3 has to be set up to counter act the 'natural' tendency to drift towards the kerb

Guys this isnt worth grinding your teeth over, if your tyres arent wearing excessively and the adjustment is correct then leave it be. You may be able to alter it slightly by swapping/replacing tyres but it will be short lived.
If your not fighting it and it doesnt shoot across the road as soon as you let the steering go then as before let it be.
As somone else as said if the steering isnt straight then you are more likely to notice this problem...get them to set thetracking with the steering straight. If your tyres are worn on edges or nearing limits then this can make it worse....infact when tyres are nearing limits on Disco 3s they have all kind of handling issues.

My 2008 HSE used to run straight for miles on a good road when on Good Year Wranglers. Now on Michelin Lattitudes, and it drifts left. I have had the tracking checked and adjusted ( I stood there while he done it ), and it is better, but not perfect. I will be checking the geometry again with my Trackrite ( one of those things that you drive over and a pointer gives an indication) to see what that says. I have used it over the last 25 years or so with total success, on less complex suspensions. My thoughts are that the rear n/s may be towing in too much, easing the back out and would give the impression that the front is heading towards the left.

Just had 20's with Pirrelli zeros changed for 19's brand new grabbers and now has a slight tendancy to drift left not there before.
Not a huge issue but would think it would indicate tyres causing the deviation, not other issues.
My previous Merc had a much stronger drift to left and was told changing the wheels round would more than likley solve the problem, but sold it before trying this solution out D4 Landmark MY16 Santorini Black THE LAST
