This is a classic symptom of too little toe in at the front, rear, or both ends.

I would get another alignment done elsewhere before chucking money at it.

And the 'upper balljoints' ?

There are none - its a MacPherson strut ffs!

Just had my 4th alignment done so its not that. My wheels are badly buckled and thats whats causing the issue. Everything has been checked now so its the only thing left. looks like bmw were right all along as thays what they said was the problem too.

It is EXACTLY that mate.

Any geo shop worth its salt should check alloy runouts BEFORE attempting an alignment.

On all machines I know of you CANNOT accurately align a car unless the wheels are true.

So its almost certain that the geo is a mile off, and this will be a prime cause of a wandering or 'twitchy' car.

Im really confused now as i took my car to kwikfit yesterday to have my front wheels balanced. Chap said his e46 had more buckled wheels then i had and hisdrove fine. Not sure if i believe that. Totally agree with what your saying MB they should have done that on all my alignments but they didnt. Im really not sure now if its my rack or wheels that are causing my loose steering. No one can fix this car, driving me nuts

CarbonSI, if you know the wheels are buckled, why not just get them replaced then see what happens? Right now, you know for a fact they're not true - until you've had the wheels replaced and the alignment redone, we won't know whether anyone's suggestions are making any difference or not...

Do you think that buckled front wheels could cause such bad handling?

Get them refurbed and straightened by Lepsons or try someone else's unbent wheels, but whatever you decide please just get on with it!

I know im having a moan but there have also been people on here who have advised that slight buckles wont make any difference to what im getting. These forums are a place to let off steam and its hardly mature to respond with 'whatever you decide just get on with it'.....

Maybe a little buckle wont upset a car too much.
If that is the only thing not correct with the car.

But trying to align four corners with bent wheels just wont work.
In fact it might actually make things worse if adjusted incorrectly.

Replace the substandard parts, get the geometry re-aligned, and see how it goes.
My guess is it will be fine

Do hope so mate Well ive taken the plunge and just bought two new 216 motorsport alloys which should be with me on friday. I will get the alignment as soon as they arrive. Do you mean that if you align a car with bent wheels that it will go out of alignment again after a few mins of driving? As i cant see how having bent wheels would make any diff to the alignmet at the time of doing it??

All of the measurements are taken using targets that clip to the wheels and are measured using lasers, so if the wheel is out of true, the targets won't be true either, so the alignment won't be correct...

Yup.

Thats exactly what I was aluding to.

Sorry if I didn't make it clear SI

You set up all the angles, some of which are as small as 1/60th of a degree, and then when you turn the bent wheel its all reading different.
A bent wheel wont throw it out of alignment, but a bent wheel will stop the technician getting these tiny geometry angles correct.
You see- you clip the datum points onto the wheels like Sean says, but you have no idea if they are pointing the right way if the wheels are bent.

Just doesn't work

Thanks guys for clearing this up. I forget how sensitive the measurement that it takes. Im just praying when i fit these new wheels that i see an improvement..

Well got the new wheels fitted and car aligned. Still not happy with steering. My fathers had a drive and thinks its fine compared to before. Must be i just dont like this particular pas on the si. The later epas system with servotronic might suit my needs better...

Sorry to hear that you still not sorted this issue out, perhaps take a test drive of the same model to see if there is any difference?

Cheers mate im so gutted. Spent around 1700 on it now. bought it in feb 11. Theyve got one like mine at a dealer in leciester but ive had enough now. it will be a massive downgrade in badge but i think im gonna go for a clio 200 with cup pack. Think that will give me the thrill im after for 10k. Anyone on here rate them, test driven one. Used to have the one down from a williams and that was proly the best car ive driven (which i owned)

I have a 335i with classic hydraulic PAS.
Also have the 318d with Electric servo steering.

My preference is the older system, the electric PAS is numb - it's good but not the same.

As for the Renaults I had the R26 Megane just before dipping into BMW for the first time and the 335i.
Fantastic little car, just as good a drive as the Clio which I have tried, and with more punch and space.
the Clio is arguably a better looking machine, but try the R26 F1 225 also would be my reccomendation mate.
It'll kick the BMW into a cocked had on everything bar the build quality of the interior. Software will see it easily at 250bhp +
Mechanically they are good these days, but still awkward to work on!

Yeah those megane rs's always got a great write up. I like n/a engines tho and would proly opt for a clio 200. Reckon it would wipe the flaw with my si handling wise and a decent bit more oomph lol.

A lot of people dont rate that epas bmw system do they on here lol. Actually when i took mine out tonight and parked it up, felt a knock through the steering column and sounded like something was loose when wiggling the wheel. maybe the problem that has caused all this in the first place has reared its ugly head....

Oh!

That may be good news if you can feel it that easily.
Rather than faf about why not take it to a tough MOT station and they'll probably find it?
Halfords online 1/2 price MOTs are guaranteed to find as much reapir work as possible LOL!

Many things can cause this. many.
Track rods - outer ends and inner balljoints.
Lower control arm balls, radius arm balls or hydro bushes.
A failing turret top bearing. Rack mounts loose, broken spring? etc etc.

All easy to fix and any one part should be less than 100.

GL, you need some luck!

I think these might be worn on my car - http://www.google.co.uk/url?sa=t&sou...odfyjhtl-JV0og

Does the e90 have same control arm bushes as the e46?


Lol just realised that the e90 doesnt have a lower control arm!
