I heard others saying that GM knuckles can be put on a Ford axle as well as other exchanges. I really knew nothing about knuckles, spindles, hubs, etc. until I took on this project. Therefore I have to rely on others to tell me "this will work". But if so many different knuckles fit on the same axle, why are there so many different knuckles?
The knuckle I just put on (36646) seemed to work at first. The knuckle, hub, spindle, axle all work fine. It was when I went to install the brake caliper that something did not seem right. It's still on the Bronco, still assembled, so comparing the 2 was difficult. Best I can tell, the 36646 is bigger toward the rear of the bronco. My caliper was hitting it before I was able to align the holes for mounting it. Then I noticed the tie rod hole (?) measures about 1" farther out than the other.
BTW, how tight should nuts be on the ball joints?
And what if the split coupling with outside threads that came with them?
I emailed Tom's once before with no response. I did email him again last night.
sprinks, I will definitely try them.
