Hard to say without actually driving, but Intrade has a good point with what he posted - have replaced those bushes (was actually cheaper to just do the whole arm) before for similar reasons to this.

Could still be a few other things though. I bet the place that did the W/A wouldn't of checked it for play in the steering . I can't count how many cars we've had come from Beaurepaires or similar that's just had a W/A done but has play in the tie rods or in the rack itself.

Could also be tyres, etc as well. Like i said hard to say without actually looking at the vehicle.

You won't get any play out of those bushes Intrade linked you to if the car is lifted up either, need to be checked while on the ground. Or as he suggested inspect them for any cracking etc.

Split/crack in front end subframe/crossmember! Possible even bent.

You can usually only see a split when its sitting on the ground (full weight of vehicle on it)

are you running directional tyres on the front by any chance!

had a similar problem and after a lot of stuffing around with wheel alignment, suspension bushes etc,which we couldn't fault, we found a broken engine mount. Replaced that. problem solved. Worth a try in your case.

the mondeos do not tolerate cheap nasty tyres. we put some cheap ones on ours.never again. they do tend to load the steering wheel when accelerating but hats because they actually have steering feel unlike jap cars which are so over assisted its not funny.
also the front "subframe" on the mondy is actually two rails running front to rear. the subframes have to be aligned to the chassis with special alignment tools. you can have the suspension aligned but if the subframes are out then you are wasting your time.also a commmon fault on them is the rear subframe mounting bushes are soft andcan lead to clunking in the rear or wandering.

Err, the front subframe is actually a box like section. The latest mondeo's are two rails like you said but the older one is basically a big square/box shape for the subframe.

Still, good idea to check all the bushes etc in the subframe (front and rear) as they can lead to it.

fordcrzy, Aug 20, 6:57am
what i was getting at was that the subframe wasnt a full triangulated "square" type subframe in that it spans side to side between the chassis rails like how you would think a subframe would. they just run front/rear.

Does the car have the original wheels on it!If somebody has fitted after market mags to this vehicle I would say that the offset is incorrect!

unbeatabull, Aug 20, 8:00am
It does run side to side, the Steering rack is mounted to it at the rear and radiator mounted to it at the front.

the mondeo front subframe is NOT a rigid body! it moves! and IT NEEDS TO BE ALIGNED TO THE CHASSIS WITH GOOD BUSHES!
you can do a static algnment and get it "right" but if the subframe is not aligned to the chassis or the bushes are worn (especially the rear ones on the front subframe) your car will pull and move around.
before i looked at any suspension bushes, i would be looking at subframe bushes FIRST.

One of you is talking about the subframe make-up, the other is talking about how the subframe is mounted to the body.

hopped in a "rental " once and under heavy acceleration it threw badly to the left. . Checking it out on side of road revealed 1 broken engine mount. Probably a very rare occurrence, but worth a glance

bayrock, Aug 24, 11:47pm
Does the car have the correct wheels on IT!

ema1, Aug 25, 12:09am
Got to be an alignment fault there still to be as pronounced as you say!
I'll bet the car has either had a prang some stage which has NOT been fixed to high standards or it has different wheelbase lengths between the left and right side due to a prang which has NOT been checked out at all!
It's my bet also that the wheel alignment chap who did the job was utterly useless at his job!
Believe me that does happen.
After all you do notice the odd car "crab walking" on roads mostly noticeable when following them at times, why I saw one only the other day and funny enough it was a Mondeo wagon.about the early 2000's model.
Another give away with that particular car when about 30minutes later I pulled up behind it outside a place I was delivering to was slightly different color toning in it's metallic light blue paint, showing up in the really bright sunlight at that point in time.

Regardless of how the chassis /subframe WHATEVER . is mounted . a computerized wheel alignment machine WILL show up the differences
It's up to the OPERATOR to be AWARE & understand what those figures mean.

Also adjustment nuts/brackets etc will to some degree, also show up any larger misalignment's from the original spec's.

In the beginning, it's YOUR car at fault
In the end, it's the alignment OPERATORS fault

Classic case I have of my own, was on an 88 v6 Mitsi Galant.
2 different alignment shops missed the HUGE crack 3/4's of the way around the main subframe, letting the whole beam flex.
Certainly was some ripe manure being flung that day.

mrfxit, Aug 25, 1:29am
I think you will find that most cars are made like that these days
Won't be many around where the front suspension is mounted to the monocoquechassis

mrfxit, Aug 25, 1:30am
FWD is the main cause of that & the japs simply took it to the limits.

About torque steer generally, I once had a Honda Civic wagon in the 1980's, torque steer was lethal.If you accelerated while turning, it would literally pull the steering wheel out of your hands, straighten the wheels and take you clear across the road. Got rid of that deathtrap fast.
I currently have a 1998 Primera, and my wife has a 1996 Primera.There is no detectable torque steer in those cars.If you didn't know, you wouldn't know they were front-wheel-drive vehicles.

Does the car have the original wheels on it!

My old Mitsi 3ltr v6 was good on tarseal, but you knew all about torque steer on gravel when booting it.

ceebee2, Sep 7, 10:01pm
When I worked for Mitsubishi in the late 80's through 2000 the first turbo Mirages were lethal for torque steer until they equalized the drive shaft lengths in the later models.

cjdnzl, Sep 8, 2:57am
I can't see the reasoning behind blaming unequal drive shaft lengths.As far as a drive shaft is concerned, torque in equals torque out - where else can it go!
Unless the longer drive shaft winds up - twists - under power, which would mean one wheel would get power before the other, but again I can't see the shaft twisting more than a degree or two, and in any case the function of the differential is to equalise the power fed to the wheels.
Unequal shafts does sound like wrong thinking to me.Anybody agree!Disagree!

unbeatabull, Sep 8, 3:27am
It is exactly as you said. The longer shaft twists more then the shorter shaft which means less torque at the wheel.

It's how torque sticks etc work with Rattle guns. Every try undoing a tight bolt with a long extension then try with a short extension or even without one. Far easier without.

Mate its not really an agree disagree matter. its a fact
