Re: Having alignment issues (caster)
Glad you guys caught that. I thought so, but not being a 73-87 expert I was looking around to make sure. Lots of sharp and helpful people here.

Re: Having alignment issues (caster)
That's a good catch! That will definitely make a big difference on your camber numbers.

Re: Having alignment issues (caster)
Any updates on your truck?
Curious to see how much your specs will change when they get everything installed properly.

That being said, I don't see how the orientation would significantly impact the alignment. What I'm seeing in the pics though is an equal amount of shims/spacers on both the fore & aft studs. Positive caster would typically yield double the thickness on the front stud of shims/spacers vs the rear stud.

I completely agree with you that the shim thickness on the front stud should have been greater to add caster. You can't a whole lot in the stock configuration on our trucks, but even a little bit extra caster makes a huge difference.

Re: Having alignment issues (caster)
What exactly do the concave shims do?

Re: Having alignment issues (caster)
They provide a 'better' bite on the shaft to keep it from shifting around the small amount it possibly can.

The alignment tech installed the uppers that way. Also, there are some shims on the drivers side.

Re: Having alignment issues (caster)
Also, in an effort to get more caster would it be worth the trouble to relocate the upper ball joint 1/2 inch back. My plan would be to take some 1/8 inch flat and drill the bolt holes and cut the b
Large ball joint hole. Then plasma cut out the existing ball joint hole and then relocate, trim, and weld in the new. It looks like I can get it back about half and inch. Any idea if that would work and how much more caster positive caster that would create? Here is a rough drawing

Re: Having alignment issues (caster)
Do a search for 'caster mod' There is a good write up with pics. Most people modify their lower controller arm shaft.
I think it would be a lot safer and less labor intensive than trying to modify your ball joints...

Re: Having alignment issues (caster)
Yea I read that thread and was excited to do it until I crawled under my truck to see that my lowers are the early style (1966) which are different from the ones in the thread. I know I could get a more modern front clip but that seems like a whole lot more work than modifying my uppers.

Re: Having alignment issues (caster)
Its too bad youre not closer im going to scrap the whole front suspension from the truck im talking about. If you can get it home and need spare parts you can have it Or any parts from it. The steering box is manual but it works fine I drove it 70 on the freeway to get it to the shop before I took it apart.

Re: Having alignment issues (caster)
Everyone is right about that top shaft though. Maybe when theyre right there will be enough camber adjustment to get the caster right.

Re: Having alignment issues (caster)
Any trig experts out there? I don't have a protractor and need to get a 20 deg angle so I can more accurately align it. I plan on cutting a triangle out of sheet metal to lay down on the shop floor. If I did my math right then a 90 deg triangle with an 11" base and a 4" height will yield me a 20 deg angle... Right ?

Re: Having alignment issues (caster)
I have to say, I am an alignment specialist correcting collision damage nothing more, just getting stuff back to specs and knowing by the numbers what is damaged (often you can't see at all) and I am blown away at how little some of these guys at the alignment and tire shops known. It is mind boggling how many will say "There is no way to align it" because the computer doesn't have the correct info, they MUST have the computer tell them how to do simple adjustments! They will have ZERO understanding of the simple geometry!
We have to send stuff out every once in a while because our rack is tied up with a car or something like that and I am always amazed at the stupid stuff that they will say. VERY few of these guys have the basic understanding of the angles they are working with every day. Brian
