Alignment slightly out of specs? 850

Just had an alignment done today after the Struts,Spring seats and Strut mounts replaced.
The car goes straight down the road and wheel is 12 o clock so all good there.
But..I wanted to check out the printout with the numbers and compare to spec and found a PDF file (that also somebody else here on the forum also had found):

1995-6 850: http://www.volvoclub.org.uk/tech/service/850/WheelAlignmentSpecificationsProcedures.pdf

If these are the correct specs for my -95 Turbo wagon:

Front Toe-In: .11 To .21 inches (.23 To .43 deg.)
Front Camber: -1 To 1 deg.
Caster: 2.33 To 4.33 deg.


My values after alignment:

Front Toe in = 0.17 deg on both Left and Right, looks like they used inches value!
Camber Left = 0.2 deg Right = -1.0 deg
Caster Left = 2.0 Right = 2.5 deg

Camber is in spec and Left caster is slightly off, doesn't concern me a lot.

But the Toe-in, is this is significant deviation 0.17 instead of .23 deg on the low end of the spec?

Of course they'll fix it if I go back, just the hassle if it's not of importance.

What do you think?

on my dealer print out, toe in range is 0.12 to 0.22 degrees. 0.17 degrees is smak dab in da middle.

Caster should be 2.3 to 4.3 degrees. Camber should be 1.0 to -1.0 degrees

Those are the fronts. for rear tires:

Camber - -0.5 to -1.5 degrees Toe In (or out?) - -0.05 to 0.11 degrees

I took it to the dealer after I took it to a tire shop...the dealer was able to dial it in a little better, IMHO.

Awesome! Thank you so much ADub, I was just going to go down to the dealer to get this official info - saved me the trip :)

I was just a bit p-off after spending $80 on alignment, not to have it done to correctly to spec...

The document I was using was the Volvo shop manual from 1995 that is available for free download. I am guessing that the specs have since been slightly updated.
My shop's printout shows Volvo 850 1993 - 97 and I now see some "microscopic" digits next to my measured, that show the range almost exactly the same as your numbers. I guess there must have been an update after the official shop-manual was printed.

Good thing is that I am now all within spec, except the one Caster reading on Left Front 2.0 degrees in stead of 2.3 - 4.3, but I am not too worried about that since I think it is hard to adjust and for 3 tenths on caster I am not going to loose any sleep...
I have a feeling that Toe in and Camber is more important for even tire-wear and the car does run straight and true :)

Now I can move on to some detailing of the interior and freshen up that black leather with some conditioner.

Do the math on the toe in specs. If it is degrees, the the 17 equates to about .10 inch instead of the minimum value of .11 Pretty darn close in my book and it should not have a bearing on tire wear.

Measure the tread on the front tires, if you are concerned, and note any wear after about 1,000 miles. I doubt you will find any problems.

In my opinion, alignments from the run of the mill tire places and even dealers are highly suspect. Had a VW dealer do my Golf some time back, but it never felt right, even though the print out said all was well. Solution find a real shop that knows and understand this stuff; however, that will not be easy and the alignment will be more like 90 - 100 bucks instead of 60 (at least where I live).

Does the car drive well, if so, I wouldn't sweat it too much until I noted some issue like unusual tire wear or pulling to left/right, etc. Again, just my opinion.

I have a printout at home from an alignment I had done by the dealer after getting rearended. I'll look it up and see what numbers they posted.

Everything was in spec, yet the car still pulls to the right. SO even though everything passes muster on the machine, doesn't mean its all hunky dory. They checked the frame, etc (as I wasn't paying for it - All State did.)
