Guys and Gals,

I am trying to research rear alignment values on 3rd and 4th gen cars over time. What I am hoping to be able to get is the rear alignment specs from every f-body shop manual from 1982 through 2002. This may be the only place on the planet (other than some magical GM library in Detroit) where this may be possible.

For example, here is the page from the 1995 F-Body GM Shop Manual detailing the alignment specs for the 1995 model year:
http://shbox.com/1/alignment_specs.jpg

If you have a shop manual and are willing to contribute, please add the rear specs from your manual to this thread (assuming the year that you have isn't already posted).

Thanks,

Keith

Keith let me look at what I have here. Program wont let me cut and paste and have to hand write. Let me see what I can come up. I been super busy with my paying winter project so that comes first. John

I've got a 2001 factory manual, I should be able to check it and my 1988 and 1990 factory manuals are at a friends house right now.

The 1993 mannual states the same as the 95 you posted with the exception being that max rear camber is listed as 0.6 not 1.6.

I could only find rear caster and thrust angle in my 2001 manual (the set of three), Kevin. Maybe I was still at a coffee defecit, so if you find a rear camber spec please post the page number

From the 1999 Helms book, page 3-9:

Front Caster: Set 4.5 to 5.5, Check 4.0 to 6.0
Cross Caster (Front): Set -0.7 to 0.7, Check -0.7 to 0.7
Front Camber: Set -0.1 to 0.9, Check -0.6 to 1.4
Cross Camber (Front): -0.7 to 0.7, Check -0.7 to 0.7
Individual Toe (Front): Set -0.1 to 0.1, Check -0.1 to 0.1
Total Toe (Front): Set -0.2 to 0.2, Check -0.2 to 0.2
Steering Wheel Angle (Front): Set -3.5 to 3.5, Check -3.5 to 3.5
Rear Camber: Set -0.6 to 0.6, Check -0.6 to 0.6
Cross Camber (Rear): Set -0.6 to 0.6, Check -0.6 to 0.6
Total Toe (Rear): Set -0.3 to 0.3, Check -0.3 to 0.3
Rear Thrust Angle: Set -0.15 to 0.15, Check -0.15 to 0.15

I've got an 02 factory manual, will check tonight.

I'll look at my 94 manual tonight and post then.

The 2002 manual shows rear toe between -0.3 to 0.3.
Thrust angle -0.25 to 0.25.

I didn't see anything about camber.

1997 Factory service manual, page 3A-7:

Rear Camber
0.0 +/- 0.6 Set
0.0 +/- 1.6 Check

Rear Cross Camber
0.0 +/- 0.6 Set
0.0 +/- 0.6 Check

Total Toe
0.0 +/- 0.3 Set
0.0 +/- 0.3 Check

Thrust Angle
0.0 +/- 0.15 Set
0.0 +/- 0.15 Check

I don't have a GM Techline DVD manual (and I don't know how to make copies ) that doesn't list the alignment specifications for 1998-2005 (2002 in case of camaro).

copy & paste was too much effort, and forum doesn't take html so

PDF linky: 1998 to 2002 alignment specs

as you'll see in the linky I posted these rear camber numbers were eliminated (as in the mention of rear camber) in 2001 and 2002 manuals.

Hmmm, in 2001 they also reduced the nominal front caster and increased the rear thrust angle tolerance range

That's strange, considering my 2001 is a caster freak with more than most

I have created a table containing the rear camber specs by year using the information that we have already seen in this post so far.

It's 252k jpg file. Anyone willing to host it so I can include it here?

As new information becomes available, I will update it and again make it available.

Keith you just want rear setting only? I have every setting from 82-current. Just going to take some time to copy it.

Let me know John

Send an e-mail to Eric. Since it's usefull racing information, there shouldn't be any problem putting it on autoxphotos.com. He'll give you instructions on how to do it yourself.

John,

I am interested in what GM was saying regarding rear camber. It seems that there was an evolution in the specs for essentially the same part and I am trying to make sense of it.

I am not sure what form your information is but I would be glad to type the information in if it is in an e-mailable form.

Keith

I'll get to it some time today. Thanks.

Keith this info is from alldata here at work. The program does not allow me to cut and paste info. So I have to handy copy all the info. I've got everything from 82 and up, some of the info might be repeated but it just takes me some time to do this. I've been busy with my other project at nights, spare time has been hard to come buy as of late.

John

This isn't time-critical so don't knock yourself out.

Here is what I have so far in text form:

Model Year Rear Camber “Set” Rear Camber “Check”
1982 None specified -3° to +5°
1983
1984
1985
1986
1987
1988
1989
1990
1991
1992 None specified None specified
1993 +/- 0.6° +/- 0.6°
1994 +/- 0.6° +/- 1.6°
1995 +/- 0.6° +/- 1.6°
1996
1997 +/- 0.6° +/- 1.6°
1998 +/- 0.6° +/- 1.6°
1999 +/- 0.6° +/- 0.6°
2000 +/- 0.6° +/- 0.6°
2001 None specified None specified
2002 None specified None specified

RATS! I made them all line up nice and it stripped out the duplicate spaces...

use non-breaking spaces... &.nbsp; (without the . after the &)

Any new information available here?

This is the only info I could find mentioniong the rear axle alignment at all...sourced from 1982 Shop manual

Wow, up to 5 degrees positive?

If I did my math right, the top of the tire would be 2.25 inches further out than the bottom of the tire... That's a lot.

Ok, so I think that proves beyond a shadow of a doubt that alignment numbers on these manuals didnt get the QA/QC they deserved 5 degrees...that's funny

The plot thickens. I love a story with unexpected twists and turns.

Sorry for the delay.

1994 +/- 0.6° +/- 0.6°

Hmm, I know this doesn't help for the rear, but the alignment guy that Jeff94TA and I use put this up for the front specs on his site, based upon what's in the Hunter database:

http://www.centralfloridastreetcars.com/al...gnmentspecs.htm

He said it doesn't have the settings for the rear because it's not designed to be adjustable :-)

My previous table has been updated. Thanks. We have all 4th gen years except for one.

I looked through my 92 service manual and couldn't find any alignment specs for anything but the front.

Allthough I like what you have down for 94, I believe Jeff94TA said it was +/- 0.6° +/- 0.6°. Which would make 95 the changeover year to +/- 1.6*.
