I have a Tera60R housing, and I need to add some knuckles to make it into a frontend. The Early Bronco C-bushing wedges measure 40" apart on the outsides. I believe the ball joint D60 knuckles are 12.25" from the weld on the axle tube to the WheelMountingSurface.
40" + 24.5" for both knuckles = 64.5" frontend.

I was hoping to keep it just under 63". Anyone know the measurement for the kingpin style knuckles?

Other considerations include;
Tera center section is setup for 3" tubing.
I would also like to add 35spline outers.

Thanks,
Brian Wickert

can you reshape your control arms to bend inward making it narrower?

Good idea, but the coil cups bolt to the top of the radius arms. That would move the coils under the frame, causing interference.

Thanks for the reply

so the more i think about this even if you end up 64.5 .....it is only 1.5 more than you were planing on which is not that big of deal.


somebody has to know what the king pin dimensions are. i would go measure mine execpt it is ball joint.

From EBML> 11.5". hope this helps

Awesome Jim, that will give me the 63" width I'm looking for. I'm assuming your measuring a Ford60. Any chance I could get you to measure the diameter of the axle tube. Seems like someone said they were 3.5", but that sounds to big??? My little axle tubes are only 3" x 1/4" DOM. Maybe I could make some kind of sleeve to fit the two together.

I wonder if there is any difference between the Ford and GM king pin setups from the knuckle out, besides spindle bolt pattern.

Would 35 spline outers go into one easier than the other?

Thanks again camo. btw, does the rainbow warrior deal have anything to do with #24 ?

LOL no the rainbow warrior started from lance paying me back for stickering his motor home with gay rainboy sticker and just kinda became our pirate4x4 joke. now as moderator of this board it is my job to fight off all the gay questions we get around here that don't have anything to do with hardcore wheeling so it just kinda stuck

Brian I thought that you had Redline knuckles? Or maybe that was someone else. I have a thought on the Redline knuckles if you have sometime and you do have the knuckles give me a call. 303-423-6152

Why are you gonna go to the trouble of building a front 60 from scratch and then slap stock radius arms on it. Or are you not doing that?
Rob

whats wrong with the stock arms. lots of guys use them when converting to 3 link up front. i plan on using them as well some day.

If you say so, but I've never seen stock bronco arms give a whole lot of flex. Why do you think everyone makes them wristed? But even then, since you are doing a good bit of fabbing anyways you could build better and stronger wristed arms pretty cheap and easy. I guess if you are looking at it from a simplicity standpoint then go with the stock arms, but building a good set of arms is definitely alot more simple than building a 60 from scratch. Why quit halfway. Just my opinion and we know what that's worth:beer:

he thought he did too ;) he is waint on redline, but decied to go his own way, and get it done sooner
I belive*

also Stock Arms are great, they are pretty beefy (don't snap but will bend if you hit them hard enough)

It should work. Also, you can save 1" on each inner knuckle by turning them down (which I did). They are 2" thick and don't need to be on a lighter truck. This is on a kingpin setup.

Case in point: my CJ front spring centers are 27.25" and i run 2" wide leafs. I built a Hybrid 9" / Dana 60 kingpin outers. There is still room for a spring plate and ubolts next to the knuckle AND the housing is only about 53" wms to wms.

Hope this helps you work it backwards...

After spending $$$$, I wasn't supposed to "go through the trouble of building a D60 frontend"!!! Don't even get me started!

Even if I didn't use the radius arms, the coils still need to be outside the frame. I suppose I could figure out a way to mount the coil cup on the knuckle. :rolleyes: I know the easy solution would be to go with coil overs. :p

I thought about building some tube radius arms, but I wouldn't gain anything. I was considering boxing the "I" beams on the radius arms with 3/16" plate to make them a little more rigid. Just seems easier then building new arms with Johnny joints, brackets for the frame and axle. Maybe when I'm ready to go coilovers I will do it then. But for now I'm happy with the way my frontend articulates (Thanks to Donovan for sharing his hinged arm with us 3-4 years ago.): http://www.bwickert.alloffroad.com/cgi-bin/i/ClawHammer/BrianClawe.JPG
What do you think?

Mark your prettty close. If I don't have my Redline parts by Thanksgiving weekend, the Tera is coming out and getting completed! I'm way tired of the B.S.!!!!!

It appears that my Redline knuckles will bolt up to a Ford Uni-setup (spindle/bearing/hub). A little machining on the hub, and I'll be set for 5 on 5.5 and half ton brakes. Guess I'll have to settle for 30 spline outers for now.

Rickb: That seems to be right on with the 11.5" measurement on the kingpin knuckle setup.

i don't have any pics handy but check out shannon cambels rig. he uses stock radius arms and i have seen them work well

It's me robellis77, I re-registered to get broncorob back, now I'm a fawking newbie again :mad3:

I didn't realize you were using a hinged arm. I'm using a similar design and it works great, so :beer:

extended stock arms can give insane flex, just look at Mike ladds bronco, that thing is?/was? crazy
