SOA conversion write up

I'm just curious if there is a detailed writeup about this. I'm thinking about doing it but I'm wondering how to do it like all of the steps involved and the cost for all the parts. If anyone has any information that would be great.

I have posted a list of items I used numerous times & posted 100's of pics and did write-ups along the way.

The search feature is your friend.

If you took the first step & listed your intentions concerning which parts you would like to use, that would be a good start. I really don't feel like writing down everything I did & then it turns out you aren't going to use the items I used, that would be useless, that's why I mentioned you need a list or at least a partial one first.

If you intend to use a D35, I don't have any advice except you really need to start rethinking this.

100% agree with joe, google is free, and there are a million write ups on this very subject.
a few things to consider....
a)if you want to do it on a tight budget, forget it.
b)if you cant weld to a reasonable high standard, forget it.
c)if you are in love with the dana 35, forget it.
d)if you cant afford bigger tires than 33's, forget it.
e)if you dont want to run a sye, forget it.

there are the basics for ye........ do it right, or dont do it at all. done cheaply/incorrectly, you would be a liability to yourself and everyone else on the road/trail!
read up on it, then if you have specific questions, feel free to post up!

Agree 100%. Don't try to do things on the cheap and think that the 90 dollar solution is just as good as the 250 solution. The more you try to cheap on things (including the D35 axle) the longer it will take and more time and money you will invest in the long run. I know because thats where I'm at. Redoing a lot of that stuff is not fun. Get a real full SYE, a new rear axle at least, and new tires at a minimum in addition to the suspension and steering aspects.

I agree with all the above. If you are coming from a 0-2.5" lift with no SYE, it's going to cost you $1500 or so to do a SYE. Leafs=650, perches/ubolts=100, shocks=200, steering=150+, brake lines=50, SYE=250, driveshafts=??

Do it right or don't do it. That actually applies to anything anytime.

Thanks guys I don't think I will go SOA at least not yet expecially for the type of wheeling I do. I plan on running 33" tires. Also I'll probably stick a 3 and 1/2"-4" lift on there. Will I still need a CV driveshaft and SYE kit? I'll probably keep the D35 in their unless I can find an 8.8 with the proper gear ratio. Now a couple of questions what gear ratio should I be looking at. Do you think that gears would be the best bang for your buck at getting the motivation back after getting bigger tires on? The reason I'm thinking of leaving the D35 back there is because I'm running the 4.2L and automatic trans whic (should) have 3.54 in it. It feels pretty slow with 29" street tires on it. Thanks for all the help so far guys.
