Well, like it says. I just got done today welding new perches on this axle and now I'm 2nd guessing myself. I leveled up the inner knuckles and went to town on perches. Now, leveling out the perches it seems that I'm really not gaining much pinion angle.
Im doing 2 post: 1st YOU MUST PAY ATTENTION TO THE WOOD 2x4 on top.
The 1st pics are the way it sits now level and inner knuckles straight up and down.This, I'm not sure if I like the pinion angle.

Now, here is where I think the pinion would help the best. I'm really uneducated on the whole caster of axles and not sure about it.
So, if you look at the wood 2x4 on top now its standing up for a little higher pinion angle. Now, the inner knuckles are tilted forward. The top flat spots for bolting stuff on are now level.

So, What should I do?:dunno::dunno: Appreciate any help.

What truck is this going it?

#1 concern is caster angle. The angle needed depends on your use, but 4-6 degrees is common.

Pinion angle is a secondary concern unless this is a slow speed, trailered rig. It could've been adjusted before the c's were welded to the tubes, but looks like that bridge has been crossed.
 
Thanks for the info. It is going on a traii rig that doesnt ever get too fast at all. Maybe once and a great while street driven.
 
I think i can simplify it for you, When the axle is under the truck, at ride height, and "done", the part of the knuckle that you "leveled", should end up about 6*up in the front compared to the road.

EDIT: Remember, that caster is figured from the surface of the road. Nothing else. So, you need to know how the axle will sit in the truck so that you can set your caster. Dont underestimate the importance of caster! As you approach 0* of caster, you have a worse driving truck and a MUCH higher likelihood of death wobble!
 
Now, the first thing you need to really figure out, is the degree that that the leafs will have at the mounting pad position. If that is level, All you need to do is level the perches and have the knuckles about 6* up in the front. Make sense?

EDIT: Also, unless you are lifting more than about 8" or so, dont worry to awfully much about the front pinion angle. Specially with a high pinion.
 
Got it.

Long story short, y5mgisi touched on this:

Back when the axle was just tubes, with no c's no it, the pinion angle and caster could've been set to anything. Now that the c's are welded on, they're set. In my opinion, everything looks close so I wouldn't worry too much about any of that.

Like I posted above, the caster is the most important piece here. Normal caster is 4-6 degrees positive but trail rigs can get away with a little less. 0 caster, or negative caster, doesn't work for anything (yes, I know some Scouts had 0 deg caster from the factory, call them an exception that's totally boderline).

At this point, the pinion angle will fall wherever it falls, I don't see a problem in that department.
 
Cool. I really didnt want to cut them off and reweld some new ones on. Guy I bought it from said he got it as trade and he got it from a guy with a Blazer. So, maybe they set the C's to it. Thanks again
 
Well, when you get it mounted, check the caster angle. I get the feeling you have negative caster right now. I got $10 that says you are going to have to try again, or run heavily angled shims/zero rates.

Youre probably right. Once I get it in all check things out and see how they look. Maybe a little shim might help it out
 
I don't know how to help but I do know we're wheeling the last weekend in April so get your junk done! :haha::popcorn:

Yah and that really didn't work out for Scouts very well LOL

I have a low pinion non turned ( the cs have not been cut and turned) with about 3" of lift and my pinion angle is fine, meaning it doesn't bind up.

So with a high pinion and with how you have everything on you should be just fine.

thanks, My mind is a little more at ease. On a side Note....Anyone know if a different year brake caliper BRACKET will fit on a 78-79Hp60? Mine got all welded on by PO:doah:. Thanks
 
There's a couple ads I've noticed on Pirate for 78/79 HP60 parts, might start there. What exactly is wrong with it that it's not fixable?
 
I've seen and asked every one in tha classifieds. My pass has been ground down really bad and don't even see how a caliper will hold on. Pics to come
 
After researching all I could find out that all ford 60 brackets LOOK very similar. Anyone know which one will fit?
