Re: My caster mod (with pictures)
Thanks everyone for all these reply's and the great write up. I am starting my 67 drop and want to keep my stock spindles due to a disc conversion and this will be great. Does anyone know what the aliening specs are to be after this mod?

OE called for Zero to POS .5 Camber. I target NEG .5 Camber. For caster, I request as much as possible w/o impacting my Camber target. These C10's didn't have much Caster to begin with. If you can get 5° that's pretty decent (I was able to yield 6.9/7.4 for reference). Toe was pretty close to OE. The larger/wider the foot-print, there might be need to adjust to account for the increased contact patch.

Re: My caster mod (with pictures)
I know this is an old thread but I did this mod to my 67 and I have severe tire scrub when I turn, is it normal ?

Re: My caster mod (with pictures)
Not sure on caster need to find a shop I trust. Set at home Toe is 1/8" camber is close to 0. Drives good just when I back out of a parking spot and turn the wheels hard one of them will scrub bad (as in tear up grass or leave a black mark) they have a different turning radius from each other ?

I have 6.9/7.4 on my dually. Going from reverse to forward there is a shift but once you're moving it's not an issue. Toe needs to be dialed in as well.

As previously recommended get thy truck to the alignment shop. Now it is possible to install the upper control arms on the wrong sides and to put the centerlink on backwards. I have no idea how much of the front suspension you worked on but these are easy things to check before going to the alignment shop and trust me they are much cheaper to rectify at home, rather than when your truck is up on the rack. Good luck and please share your findings.

Re: My caster mod (with pictures)
It was frame up build, all new components. 2" or 2-1/2 spindles (don't remember) 1" springs etc.

Re: My caster mod (with pictures)
Ahhh.... Definitely verify the a-arms are on the correct sides & the Center-Link isn't backwards. I bet you're ok on the Center-Link because there's typically tie-rod to x-member interference when that occurs.

Re: My caster mod (with pictures)
Yeah, don't be like me and try to get it aligned with the UCAs on backwards. It won't work well.
Fist picture shows them on backwards. See how there's more angle between the UCA and the top of the spindle? Second picture shows them on the correct side. Look at how the UCA and top of the spindle are sitting more parallel. You want to have the bump stop towards the rear of the truck.

Re: My caster mod (with pictures)
Yes I see, the spindle is more in line with the front UCA mounting bolt too.

Re: My caster mod (with pictures)
Yes A-arms on correct side, as my helper double checked all my work on the truck.

Re: My caster mod (with pictures)
So if I use tubular control arms for my 67 build I will not have this caster issue, is that correct?

Some tubular arms are nothing more than a copy of the OE stamped steel arm while others might refine some of the geometry by making changes.
