Default What caster angle?

I picked up a axle that needs the caster set and the inner C's welded on.

Does anyone know what the factory caster setting is on a D44 frt axle?
I'm looking for a baseline to start from.

Should I set it to 6-7 degrees or more? My jeep has 4" of lift (springs) and its from a '78 Ford Bronco if it matters.

thx

I had my outers off at the ball joints put the housing under my jeep set pinion angle put a steel rod up through ball joint holes and used a angle finder. I cut the welds out of the axle tubes to punkin and just turned tubes in punkin was easier then I thought it would be. Top ball joint behind bottom

Thanks...I'll have to rotate the C's, the tubes are freshly welded to the pumpkin.
No biggie though.

One other thing....did you Mig weld the tube to the cast steel or use a stick welder and Hi-nickle content rod?

I used an arc welder with Hi-nickle rod 70-18 seemed to take more power than other welding I have done to get it to flow good

if you are saying 7018 is what you used that is not a high nickle rod meant for cast. remember when arc welding cast with a high nickle rod you need to follow different procedures than standard welding.
1- pre heat metal
2- de-stress the weld with a hammer and punch after every rod
3-wrap in fiberglass or build a hot box to let the metal come down in temperature very slowly or it will crack.

I generally like around 6-7 degrees.

You are correct, that you set it off the ball joint/kingpin axis.

Don't forget to dial in your pinion angle at the same time.

Last one I did was for my toyota, set the knuckles at 7* caster, and pinion 5* up from stock.

This is a High Pinion D44 (ford)
If I set the pinion for a double carden joint drive shaft (point it at the t-case output)
Are there any special considerations for the oil level?
One blurb I read was to use a mid 70's F250 cover becouse it has a higher fill plug.

Is there anything else I am missing or tricks I need to know?
This will be driven to and from the trails, across several states at a time.
It needs to last.

thx for all the help everyone
