Correct C bushings 2.5 inch lift, front pinion yoke pointing up, down or straight?

[Timmy390]

I’m in the boat with what seems like most others. My 74 drives like crap at speed on an uneven or bumpy road. Because of this, I try to read most of the posts on steering issues.

I keep reading references to the front pinion yoke angle in combination with C bushings. My 74 has a 2.5 inch lift and I put 4 degree bushings on it years ago. My pinion yoke points up which at the time I figured was a good thing. Now I’m reading it’s a bad thing.

What should the angle be?

Should I go4 degree or 7 degree?

My guess is I put the dang things on wrong and that’s why it’s pointing up but I need a “line in the sand” answer as to what’s correct.

Ideally you want your pinion to point upward and at the same time still have at least 4 degrees of caster. unfortunately with fords set up in stock form with a lift, you can't have both. If your pinion is pointing upward right now, you probably don't have enough caster and that to me is more important than correct pinion angle. I like to put the 7 degree bushings in with any lift that isn't getting longer arms or radius arm drop brackets. I would also venture to say that these eb's didn't have enough caster to begin with.

Thanks, I'll put some 7 degree bushings on there and see how it drives.
