Does anybody have the specs for the Wheel Alignment?
I have a CC T3 Auto and I find it lively on surface undulations as if it is toeing out too much.

After getting it checked the alignment came back ok.
But if the camber of the road rolls to the left the car will track left (and vice versa). This makes it very difficult to steer a straight line as the camber changes.
Worst journey is on the M25 anti clockwise around junction 4. The outside lane changes from a fall to the right over a very short distance to a fall to the left. So I find myself originally holding the wheel to the left (against the camber) and then having to hold it to the right and a small swerve to compensate.

I've been following some Ford Focus sites and it seems that a setting of +0.10 Degrees (+/- 0.20 Degrees tolerance) is a better setting. So this is a positive figure giving the bias to Toe In which is extremely unusual for a front wheel drive. It is expected that torque through a front wheel drive axle will pull the alignment towards Toe In so they usually start with Toe Out of about -0.40 Degrees.

I still don't know what the published figure is for the V40cc. I can't find it anywhere. But based on the Focus forums I'm going to get mine reset as close as I can get to zero.

Had ours (2014 CC T5 auto) done recently and the vehicle specs that came back on the report are as follows:
Front
Toe: 0.6-1.8mm, equal both sides (0.3-0.9mm)
Caster: each side 3.1ᵒ to 6.1ᵒ
Camber: -1.2ᵒ to 0.2ᵒ
Rear
Toe: 1.2-2.4mm, again equal both sides
Camber: -2.3ᵒ to -0.3ᵒ

Interesting. First I'll have to convert that to degrees! I don't know why it would be quoted as a linear measurement because it changes for the size of wheel. I'll assume you have 17 inch wheels.

Do you think the values you've been given are definitely positive? Giving Toe In rather than Toe Out?

Right. Conversion done...
Positive 0.08 Degrees to Positive 0.23 Degrees (Total Toe so half for each wheel)
EDIT (now with correct maths!)
For comparison, the Focus figures above would be Negative 0.10 Degrees to Positive 0.30 Degrees

Decided to adjust the steering for less Toe Out. A quarter turn on each track rod end. But I couldn't get the wheels off. The centre hubs were welded Alloy to Steel hub. So I resorted to an old trick. All wheel nuts back on and just a quarter of a turn loose. Then up and down the drive until I heard a crack from each side.
Adjustment done and Copperslip all over the hub. I'll report how it drives then go for a proper measurement.

Had many fords inc focus and they understeer for fun if anything less than parallel. FWD needs modest toe out at front and toe in at rear. I have a report from mine somewhere with stock figures on but I it got mine set to extreme edge of out/in front and rear.

Depends how you drive and your power, I would expect a D4 set wider than a D2. Used to counter torque steer also.

I've set front wheel drives to MINUS 0.1 Degrees (slight toe out). But I'm beginning to think this chassis might need slight positive. Can you find your figures?

Here ya go

If you are 0.1 toe out each side on front you are exactly mid limit (same as mine).

Allowance is 3 to 9 minutes toe out, so it seems they actually set mine mid, not top limit.

So like many a good 'old engineer' your guesstimate was PERFECT! ;)

Thanks for that. I'm going to drive 100 miles today and see how it feels. Then I'll take it for a measurement.

The 100 mile drive was an improvement but I still felt it 'kicked' too much.
So off to get the thing measured this morning and then the normal faff of converting form their 'Decimal Degrees' to real 'Minutes'. Turns out it had (positive) 27' of Toe In (0.45 Decimal Degrees). But the rear off side wheel was at Zero with no Toe In. Possibly this is making it kick. The effect of this would make it track to the right and needing some right lock to counteract it. But my steering wheel is dead ahead and therefore just adjusting the rear would leave me applying left lock to counteract the new rear axle setting.
So I decided to set everything back to factory specs. Which for the front is 12' Toe In (0.20 Decimal degrees)
I'll see how it drives before adjusting again. If it's still wandering as the camber changes I'll wind it up to 18' Toe In which is the top of the factory range. If it has settled down I might try 6' Toe In (the lowest factory setting) to improve turn in.

What on earth?

I sent you the factory spec? It isn't toe in at all, let alone 12' of toe in.

Thrust angle needs to be zero, I would just take it a 4 wheel alignment specialist with the correct Volvo spec, job done.

We may be confused. The factory spec is for (positive) Toe In of 6' - 18'. That's what I got from your PDFs and confirmed by my alignment company. They show a setting called "Volvo, 2016, V40 Chassis 3, All Models" I suspect this may be unhelpful for the CC Chassis with the higher compliance. I may end up closer to Zero if I have eliminated the tracking kick that takes the car off towards the side that has the weight on it.

I get your point on CC but TBH doubt much difference. my pdf (and post) shows 3’to 9’ toe OUT as the factory limits

They are positive figures which the normal convention says is Toe In. Toe Out is normally written as -xx Minutes

I informed they were toe out, they are toe out. 3’ to 9’

If you need a 2nd assurance look at the graphic, measured front of car, plus being toe out.

You'll have to help me. The graphic has only positive figures and no mention of "Toe Out" (or Toe In). Just the word "Toe"

OK. But you've reversed conventions and are relying on the little graphic rather than the actual figures (the graphic doesn't change between any readings)
