You set the axle ball joints at 7* and then you weld the truss on at 0*. so it gives it the factory setting then you adjust your upper/lowers for pinion angle. Mine worked out perfectly as far as angles go.

 

Ideally with the double cardan at the t case your yoke will point at the output on the case. With a lift and proper castor this can be difficult. I would weld it in the same place as stock. The castor adjustment should come from the control arms. It gets complicated when you want to keep all the proper geometry ie spring buckets track bar steering and camber and set the pinion angle.

 

What about the spring buckets.... are your springs bowed?

 

Also when doing a swap like this what am i going to do about my gear box? keep it change it?

 

You have several options, one is redrill the pitman arm for one ton tie rod inserts, next is the same but use a durango steering box, and the thrid there is a steering box that is 4 bolts that isn't quite bolt in, but isn't that hard (I don't remember what it is because i'm gonna do a durango).

 

You never want your yoke pointed directly at the output. General rule with a double cardan is 2* below pointing at the output.

 

Thought that was for the rear to make up for axle wrap. Even so with lift the stock setting ( correct castor) the pinion angle will be off.

 

Nope no bow in my springs at all.

On my steering I am running hi steer/crosssover steering. Depending on what you are working with depends on what you need to do to make it work. I am running a stock pitman arm drilled for a 3/4 bolt.


On the front axle it is all about compromise. you want your caster axle as close to 7* as possible. Also you dont want to have your angles so screwed up that you are causing driveline vibes. The cool thing about having an axle with lock outs.. you really dont have to worry about that problem.

 

lets all just agree that 2 ton rockwells should have came stock lol

thats what i want...
I can dream right??

 

If I had to choose a set of axles it would have to be a set of Mogs, or daimond axle hybrid mog axles... but at 4k just for housings for stock mog.. and more then that for custom hybrids... I dont see that happening

 

Mogs all the way. With Rocks you have to lift a ton just to clear them and unless you're running 46+ inch tires they are too much. I'm thinking 14bolts front and rear for my next build. Put in a set of RCVs and you're at Rock strength with a whole lot less weight and you actually have gearing options other than 6.72.
