front axle is twisting. WTF?

My YJ was lifted about an inch in the rear when I first got it. Looked hideous. 8got the shackles to put on the rear of the rear leaf springs to lower it a bit but noticed that lowering it seems to have twisted my front axle forward. To Illustrate, imagine the differential turned forward to the point it would be difficult to add oil to it. Its It's enough to affect the steering. The steering became touchy in turns. What can be done to correct this?

These are the best pictures I can get. Hopefully you can see what I mean.

I dont see how that is possible...the only way that front axle will pivot like you said it is doing is if the saddles that the leafs are bolted against are broken off the axle tubes.

all of the steering is connected to the axle, except for the drag link, so the spacing shouldnt change even if the axle is loose, as in loose u-bolts.

check for shims

Wonder if someone had a humungus lift and wanted to change the angle of the driveshaft by installing shim. Not realizing that would effect the caster and the steering.

Think it's twisted beside the leaf springs are flat. The springs relax and everything attached to them has no code but to roll forward, at least in my mind. Needs new springs anyway. What would be there biggest lift springs I could use without modifying anything else?

The springs dont look right to me...they have 5 leafs instead of 4 and have some odd insulator too. You might want to check your tire pressure too

...stock springs are flat. I would definitely check for shims. The pinion does look a little on the high side for stock. Also make sure the shackles are correct up front. I have insulators like that on my springs...but they ain't stock!

I know the tire pressure is a bit low. I checked for shims and found none. The springs are definitely flat and I am thinking that's the whole problem. Am looking for a now set now but don't want to mod anything else if I were to put on a set that lifted a bit over factory. However simply replacing with oem springs should get me a bit higher than I am now. What spring weight capacity do I need? They are available from 680 up to1080 lbs that I have seen.

How many miles are on them? Are the tires wearing funny?

But if the springs were flat. And I do mean flat. And the axle is bolted solid to it, wouldn't that tilt the axle forward?

actually judging by your pic they aren't 100 percent flat. but to answer your question the tilt comes from the mount or shim, not the spring or flatness there of. get me a pic of it from the front dead on and let me have a look at it.

Your springs and pinion angle are fine....but you need to address those shackles

I knew that was coming. But the shackles themselves wouldn't cause my problem.

Sure they can. They look bent which means your springs are no longer centered under the front which changes the whole geometry.

Hmmm. Sounds odd to me, but worth a shot. Will order a set before I spend a bunch on springs I may not need.

I dont care too much for those but everyone likes different stuff. Stock shackles work for 90 percent of the jeepers. I used currie ones on mine because I didnt have any stock ones laying around.

Those shackles made me LOL. Looks like a 12yr old made them.

Get some good new stock shackles then report back.

They are actually available at AutoZone and not my handwork. I just got this jeep at a steal and figured if this its all I have to do to it I am ahead of the curve

The shackles looking bent as Ibuildem said brings another question to mind. What do the bushings look like? There are bushing in the spring eyes and in the frame where the shackle connects. They very well could have been eaten away by that awesome shackle lift attempt/fail.
