Alignment help

Idk if there are offset ball jts for these axles but doesn’t matter. OPs camber is perfect.

so maybe the guys alignment program punched in random numbers for what it should be because if the specs

Going to be a couple of weeks before I can get back to the shop to ask, but Aurora Girls info sounds plausible.

Id also say that to be honest I do not trust the person who did the alignment because the print out had the wrong spec according to FSM(which is not necessarily 100%... depends on if gm put out a TSB or not), but if he didnt bother putting the right spec in, did he infact properly even get a check on it? basically, maybe see if any shops offer free alignemtn checks or if you dont mind spending more maybe something.. different.. idk.
maybe go take measurements best you can and then if you do it as best you can, and its not discernably negative or its not excessive, then send it. its a 4x4 87 its not like youre expecting 80k out of your tires (probably?)

No, it doesn’t sound plausible and I’m not certain why you’re worried about with your alignment printout. (Except why the rear looks wonky and why a 4 wheel alignment would even be done on a solid rear axle is beyond me. Unless maybe trying to chase down an obvious issue with the rear like a bent axle or something.)

Unless there is more to this, your alignment is _____ing perfect. Although ideally I would like a tad more + toe (toe in). But if the truck isn’t wandering all over the road, not eating tires and all the steering components are tight, your mission is complete! Lol

im sorry you dont like me but please be my guest and go look at the FSM where I got the ******* specs from.

Why are you trying to read more into this to prove some point?
There is not even a “spec” shown on the printout. Only an actual (which we don’t know if is before or after “adjustment”, but that is of no consequence as it’s right, correct, good as printed).
The 1.5 deg of camber “spec”, as @idahovette mentioned (not that I knew of that spec until he mentioned and you posted it) is as wrong as Kaitlynn Jenner.

I’m sorry you are taking this personally. Not meant to be. And I believe the spec you posted is true. Idahovette sort of confirmed it in this thread prior to you even posting it.
But that spec is incorrect for camber. Without question.

1.5 (Presumably stock? or common , an overall OK number?) degrees plus or minus .75 degrees. shouldnt become that much off that spec.
As I said to him, if this is actually true and all that, that he had almost zero, I wouldnt be worried. but being the guy who did the alignment has a lot of suspicious stuff, such as the SPECS FOR CAMBER saying they should be 1 to 2 degrees. then I do not trust it

But Im not him. If he doesnt notice anything visually, with any checking, tire related, or handling, then hes probably fine.

Thats why. I wouldnt doctor up a chart to misdirect someone and I provided GMs spec listing to clear up any wondering, and I also noted that its not necessarily "the" spec because they could have always changed it whenever they wanted and that TSB would be old enough to not be readily found and a lot of machines/databases may still use the one pictured while there could exist a "new" one

The nominal part makes me think its been misinterpreted as being strict 1.5 +/- .75 when I Read it as a value one may reasonably get on a good truck(no issues) and the +/- gives it possibly an acceptable contact patch while wheels turned agressively out, and because its for v30 as well as v10, maybe its to accomdoate kingpins which to my understanding will have different camber when turned all the way (which is also a shorter radius)
Are oneo the ball joints more prone to wear generally? if so that could be to accomodate that

I just did a deeper search to find any TSBs or official data, I did not find anymore. oh well

Again, I do not doubt what you posted. But it was bad intel in 1978 (apparently) and still is.
And that said, I’ll take my solid axle trucks with no camber please.
(As well as most all IFS vehicles for static camber).

Another useless thread down the rabbit hole. I agree with Grit dog. Now let's talk about something useful....fuel milage.....oil preference... gas guage reads empty...yada yada.

@bucket ....handling....really Andy?..we are talking 4wd here......lol.. There are shims for camber changes that go between the spindle and axle housing that I have used for YEARS and also different degrees of sleeves to use on the upper ball joint. The shims work very well, better than the sleeves IMO. Never seen offset ball joints for a K series?

Hey hey, I made sure to say it's not needed on a 4x4, lol.

I run about 2° negative on my Celebrity. The tires hate it, but it sure has great turn-in response on the high speed corners. Fun is more important than tire life

thats old alignment specs before he adjusted anything, wheres new specs after adjustment
