Okay,
For those of you have read my previous threads, I have asked some "nubieish" questions concerning axle swapping, spring hangers, etc.
My Jeep is in the frame state with NO spring or shackle hangers and I have option to do what ever I want since its a complete built. Problem is that I'm now on a time crunch before having to move back to AZ per the Military. Leaving in November 15th and I have to have a rolling chassis by Oct 31st so I can tow it. I have purchased Dana 44 axles from a 1990 Waggy (Thanx to 1BIGAZZBURBN) and now I need help figuring out what I need to do to make it work ASAP. Pictures will be greatly appreciated :confused:
The Idea is
37'', Street and Trail Drivability, Stock tranny and Xfer case on a YJ.
My problems are
1) Shackle Reverse, I have read that for street drivability it might not be the way to go.. What mods will I need to do to incorporate this with SOA and DANA 44's? And should I even bother?
2) Dana 44 front and rear SOA. The front is my main concern. I have measured the springs, perches off the OLD and NEW axles and BOTH are measuring 31” from center spring to center spring. DSD and the spring lands on the outer tube of the Diff. I have read people welding perches on to that and or grinding a pad into it. Best practices please..
I have been advised that I should outboard my springs for both or just SOA application but I have researched and I have found nothing of that nature.
All Help is GREATLY appreciated! And if I have overlooked anything please Please Please let me Know!
Thanks!
 
In the rear I would just cut the perches off teh axle and move them where you need them. If you were going to stay spring under up front I would suggest just doing a little grinding and running the hangers where they belong on a YJ, as that's what I did and it worked great. Since you're starting from scratch though I'd look for a spring over type perch that welds on your waggy front axle and just outboard the springs 1/4 or 1/2 inch per side (I forget how much would be needed) I've seen a few booty fabbed waggy front still in waggy's that were SOA and they just drilled a hole and let the spring ride on the rounded upper part of the casting :eek: As for the u bolts if it were me I'd just run a squared off u bolt to wrap over the existing perch, maybe with minimal grinding so it can't wiggle around. Then just run a round one to wrap under the tube beside the casting. I hope that helps a little.
 
get the longer MORE perches to fight axle wrap. they also sell weld it yourself shackle reversal hangers

Sorry for all the questions guys, this is my first build...
Another question, is the D44 off a 1990 Waggy the HD? Sizing for ordering the correct perches..
Also, I have the springs off the D35 and they are pretty rusted but looks to be only surface rust... Should clean them up, repaint etc or buy new ones? I dont know who makes them but its 5 leaf in the front and 4 in the rear....

Click to expand...

If they're stock YJ springs then you could use them. personally I wouldn't use lift springs to go spring over. 37s or 38s are about as big as you'll safely be able to go without concerns over breaking D44s. Going SOA it probably won't need lift springs to clear 37s. I'm running RE 1.5 SOA springs for my SOA project but i'm also going with 3/4 ton chevy parts.
 
Got all my crap! Thanx guys... Does anybody know what AMP rating is necessary to weld spring hangers to frame and perches to axle? I'm not trying to re-wire my home for 220v welder...
 
Another silly question... My leaf springs have the nipple that fits into the perch on the top.. Since I'm doing a SOA Should I cut that off and replace it? Also, I'm trying to break the leaf packs apart so I can paint them since they had a nice coat of surface rust but I cant loosen that same PIECE OF S**T in the middle due to it having a round nipple :mad: Should I just cut it? And where do I get a replacement..? I'll post some pics of my PAIN IN THE ASS build so yall can see my frustration!... A little to ambitious perhaps?
 
New Effing issue! So I'm removing the front and rear bumpers that have been welded on by the genius pervious owner while waiting for and answer to the item listed on above, which I have figured out by the way. After cutting everything off I notice that something is missing... Hummmmm? Oh that’s rite, the rear bumper that had a hitch welded to it was also the rear cross member... I thought that My cross member would magically appear underneath after removing this POS bumper... Does any body have an idea what I should do? I've searched online and can’t find anything to replace it...
 
So you have no rear crossmember now. You need one. Your jeep should be fine, there is one a couple of feet further up the frame. Your gonna have to fab. There will be no bolt on solution here.

Get a buddy with a welder, some 2x4 tubing and some cut off wheels and you can fix this.
 
More Help Needed!

Okay, Sand blasting the frame this week and then its time for welding and setting up my SRS SOA..
1) Can someone tell me the proper angle that my front shackle should hang in an SRS? I am doing this with no weight being that all I have is a frame and axles.
2) What is the proper pinion angle for my front and rear D44? Should I mount the tranny and xfer case while setting the SOA?
Thanx Again!
 
Tomorrow and through the next couple of days I'll be welding the Hangers perches etc, I got tied up adding a 50A circuit in my garage.. Does anybody know the propper angle for front shackles in use with SRS? All I have is a frame so there will be little weight and minimal spring compression? Thanx!
 
20-30 degrees is what I generally do. It depends on weight(which I know is minimal at the moment), arch in the spring and the over all setup. It sounds like you got in over your head a little.
