Front drive shaft too much angle?

I have a 74 Scout II with spring over, I've already shimed front as much as I can. I had a cv style driveshaft made and it's binding up at t-case. Has Dana 20 with 1310 cv yoke.
What do you recommend to get tcase lowered to reduce angle? Do they make index ring for Dana 20?

Need help have no 4wd, lol
 
Did you cut and turn the outer c's on the axle housing? That's normally a necessary part of a spring over in order to angle the front chunk up towards the t-case.
 
I had the same exact issue when I did the SOA in my 74 Scout. An offset u-joint for the drive shaft mounting at the transfer case solved the problem. Worked like a charm both on and off road.

Either call up Jeff here at ihon,and he can order one up for ya or call up Tom woods custom drive shafts. They are the only one I know of who makes the off-set ujoint in the popular sizes. Here's the link Thier web sight.
 
I figured the cv shaft would of had enough drop in it but it doesn't. I'm running a Dana 44 from a dodge front end.
I'm running 38.5 x 14.5 x 15's the lift is about 8-10"!

What is the off set u-joint look like? How does it work

cutting the c's? Not sure on that one
 
I looked at the website and I think that cv shaft will work. Says they can get 35-40 deg out of it, I'll call em on Monday! Thks
 
Not sure if there would be enough clearance for a cv style shaft for the front, due to transmission bell housing.

Both my shafts were made by Tom woods. My rear was the cv style and the front was standard. I had the same issue with binding at the transfer casewith the front drive shaft. And the off-set u-joint that Tom woods provides will work. This is what I installed = super-flex universal. Joint That 1310 joint solved my binding issue at the transfer case.

Btw - even Jeff suggested those u-joints when I called him asking about the binding
 
I only used one super flex joint at the transfer case. Standard u-joint at the diff. I did not have any binding at the diff.

When I ordered the shaft, with standard u-joints at both ends, for the front, I wasn't aware of the binding untill I installed it. Then I checked it here in my own man cave of a shop, both on the ground with all weight on front axle and up in the air at full droop. That was when I had the binding at the transfer case. Not at the diff.

The one super flex joint swapped in at the transfer case solved the binding. Never had any issues with it while I was driving it like that. Along with highway driving, I've taken my 74 Scout off-road in hollister hills several times and the rubicon. Not once had any binding. That's with SOA and leaf springs that I believe were 2" to 2.5" over stock.

If I read your first post correctly, you mentioned that ya got more of a lift than I had. Best thing I suggest is to call them up at Tom woods. Thier customer service is great, just like the fellas at ihon. :icon_up:
 
I'm binding with wheels on ground not even drooped yet.
I'll call them see what's up. Thks for the help, gd start. I'll try and upload some pics Monday

Just assumed you were running the sii d44's which are set up SUA and require modification to go SOA. Wouldn't apply to your fa if it was already setup as SOA to begin with.
 
Ok, so I ordered a superflex u-joint to try out at tcase.
I have a 30deg angle from tcase to front diff with all weight on wheels. I'm going to a straight shaft w slip yoke and the superflex, maybe some grinding on yokes. Will it work? Million dollar ? Lol I hope so
 
Cool deal. Hope it works out for ya. I do know that that super flex joint fixed the binding issue in my 74 Scout. That was after doing the SOA and 2" springs. Maybe they are 2.5" springs
