Scout Dana 44 Questions

I picked up some scout Danas the other day. Anyway I know I need to rotate the knuckles on the front because of the 0 degree caster.

My question is can I just set those to 6 degree or should I mock them up in my jeep first and then set the caster angle?

When I narrowed my 44, I figured out what the pinion angle needed to be, set that and then set the caster angle.

Do you just point the pinion directly at the transfer case?

Point pinion at the case and then turn knuckles. That's what I did with the hp 44.

if the caster is set and the pinion isn't placed properly you could bind.

So just point the pinion at the case?

How accurately does it have to be pointed at the case?

Am I over engineering this? I mean my jeep only has a 4" lift and I'm doing a SUA.

well it would be nice to get it right on. for me, well i installed a 4" lift and seeing as i have a M38A1 my front shackles on rear ward, so it put my front end almost flat with the ground. i mean you could of put a level on the bottom of the diff and it would of been level. i bought some angled shims and gave it some angle, never had any problems with handling or bump steer but if i wasnt so lazy id would of bought a pair of new mounts and set the right angle then welded them on. i just got lucky.

Do you have a single cardan shaft in the front?

I have a double cardan shaft on my TJ and to use it without vibes the pinion has to be pointed at the t-case. Single cardan shafts are not the same however.

Just do it right the first time! I'm thinking you will have to outboard your springs, I'm not totaly sure since you are doing a SUA, but you will still need to set your left spring perch. Depending what style driveshaft you have, I would loosley clamp the axle in, set your correct pinion angle, then you can adjust you castor. It's really not that much extra work and then you won't have any drivline problems later.

Yes double cardan joint needs to be pointed at the case and the normal single ujoint style shaft you want about the same angle at each end.

So you put 10 degree caster?

Did you point the pumpkin at the transfer case?

What kind of drive shaft did you use?

Also I want to Chevy/FSJ outer knuckles and spindles with early 80's F150 hubs and rotors to keep my bolt pattern.

Will I need flat top knuckles for this, even though I am not doing SOA(I may do SOA down the road I just don't want to complicate things more than they already are right now)?

I know the ford hubs stick out pretty far...Is there another option here?

I hope that post makes sense.
