SOA question!

Hi, I bought my 95' YJ two months ago and since then I got hooked. Now I want to go for SOA and have a few questions to ask the experts "out there" (and thank you in advance, guys!!!).
I hear about the angle of the spring perch need to be line up precisely, how can I do it ( measure the angle and line up the spring perch) ? Does it has anuthing to do with the ring and pinion of the differential (front and rear) ?
Can I do the SOA with out changing the SYE and CV shaft ?
Beside a dropped Pitman arm, do I have to do anything else with the steering system ? ( just installed a new stablelizer)

In the worst scenerio, I can't afford the SOA, can I just do the block (2") for the front and the rear on the YJ while saving up for the SOA kit? (As you already know, the block kit is only $25 per axle!)

Again, any answer will very appreciated,
Quang.

P.S. by the way, I am located in central Ohio, I have been asked around the 4x4 shop, no one is willing to do the SOA conversion, even thought I insist that I will release them from any liability.

i'm sorry to break some news to you.. but if you put blocks between your axles and your springs, you'll actually lower the jeep... any spring under axle setup will be lowered if you increase the distance between the spring and the axle.

the dropped pitman arm should do you well with the steering, but you will still experience bump steer. also, you will want to relocate one end of the front tracbar, you want the tracbar and the steering drag link to be parallel with each other. you should also consider a Z bent drag link or a crossover steering system

I have successfully done the soa on a jeep without using the sye and cv shaft... i would certainly suggest using that setup though... we lowered the transfercase 1.5 inches and it has never given us one problem.

as for your main question, the perches... for the rear, you will want to point the pinion straight toward the transfercase output shaft, then down about 3-5 degrees, if you point your pinion toward the halfway line between the output, and the skidplate, you should be ok... then weld the perches parallel to the ground from there... then for the front, you want your perches to be welded parallel to the old perches, which will keep your caster angle exactly the same.

we successfully did the soa for under $100 including shocks... any more questions, please ask

Thank you for your answer, I just have a few more questions that I have to ask to clarify some of my undertsanding.

I already have a lower transfer kit on my Jeep (1.5") since I installed the supension lift, do I need to lower it more if I do the SOA ?

(This question may sound stupid), how do I get the pinion point to the right angle to the transfercase output shaft, I mean does it involve take off the differential cover and line it up or just tilt the whole axle up until it line up the right angle?

In the event that I decide to go with the SYE and CV shaft, can I just take the lower transfer case kit out and not worry about the vibes ? Also, with SYE and CV shaft, do I still need to get the correct angle for the rear axle ? Or just put the SYE and CV shaft in and not worry getting the right angle ? (They will adjust accordingly?!)

Thank you,
Quang

if you have a 1.5" TCD, you should be alright as long as you have the pinion pointed toward the output... if you are using the drop method, i would suggest pointing the pinion straight toward the output rather than a few degrees down... this way, when you finally do install the SYE, you will already be a few degrees down and won't have to readjust the pinion....

to adjust the pinion... simply turn the entire axle... when you find the right angle, weld the perches on based on how the springs will sit on it...
