I just got four-wheel alignment done on my 406 earlier this week, and the tyre shop's computer (they gave me a print-out, it's a Corghi alignment machine apparently) seems to have slightly different values than the Haynes manual. Here's what it said:

Front -
Toe: 0 ± 0.6 mm
Camber: 0° ± 30'

Rear -
Toe: 2.2 ± 0.6 mm
Camber: -1°50' ± 30'

And here's the Haynes manual specifications:

Front -
Toe: 0 ± 0.5 mm
Camber: 0° ± 30'

Rear -
Toe: 1.5 ± 0.5 mm
Camber: 1°50' ± 30'

The most obvious difference there is the rear toe, but it also seems (unless a typo in the HBOL) that Haynes is suggesting positive rear camber and the other suggests negative? My car had a negative rear camber before and after alignment.

Does anyone know what Peugeot's own specifications are for the D9 saloon? Was the suspension setup changed at all between the D8 and D9?

Before alignment my rear wheels had a toe out! I should get it checked more regularly. It feels slightly weird going over bumps now - like the rear is wobbling more horizontally on the rebound. Could this be drop links or something, or was I just used to it being wrong?

There is no adjustment for rear toe on the 406. You can only adjust the camber.

You sure about that? As I said the rear toe was adjusted on mine, and to quote the Haynes manual:

Rear wheel toe setting is also adjustable. The toe setting is adjusted by slackening and rotating the track arm inner pivot bolt.

Actually they say the camber is not adjustable, which would explain why the camber (front and rear) didn't change much with my alignment - I guess adjusting the toe would change this a bit?

Jasper 5. Won't b/s you mate
Hes spot on there's only adjustment for camber
Of which is set by the bolt on the top links,

The camber shouid be set after replacing the top links

If its not set correctly, the car will skip out at the rear end on corners

Are you sure? I know Haynes are not renowned for their flawless accuracy (there's already the discrepancy with rear camber) but there's other evidence out there that suggests rear toe is adjustable:

http://www.frenchcarforum.co.uk/forum/v ... =4&t=38247 (says both camber and toe is adjustable)
http://www.peugeotlogic.com/workshop/ws ... ign406.htm ("Toe is adjustable on the front and rear suspension", also says negative camber for rear unlike HBOL)
http://www.honestjohn.co.uk/forum/post/index.htm?t=7112

The picture in the Haynes manual describes the very bolt that you Tipp-Exed in your pictures being the one for adjusting toe.

I'm very confused now. The printout I have here says the total rear toe on my car was previously -2.3 mm and was adjusted to 4.4 mm. I can't remember what it looked like before but there is a noticeable toe-in on the rear wheels - how could they have done this if the toe is not adjustable?

I don't notice anything bad happening going around corners, it's just going over bumps and potholes it feels a bit wobbly - but as I said I could just have been used to a different wobble before.

Interesting'

So the top link bolt adjusts the camber,
So if there is a rear toe setting where is the adjustment location for that
I've never found one,

The tip ex mark ain't toe mate its camber,

Camber is 12 and 6 o'clock ain't it
And toe is 9oclock and 3 o'clock for eg
Or am I wrong

I'm going back to sleep now.

The weirdness I was describing before seems to have disappeared after replacing the rear tyres - I guess the adjustments that were made are more suited to tyres with 8 mm tread, not 1.6
