Front Shackles

Does anyone know what would cause my front shackles to do this?

Bent and/or cracked shackle mount is one of the common causes. Whats it look like compared to the other side? //---\\ , //---// or //---||

Should there be a bolt in the middle too (three total)?

No. It's a welded tube

Mine.

I would also suspect the centering pin that holds the spring being worn, as well as the spring perch that's welded to the axle . This would be caused by the U bolts being loose, and the axle moving around.

I restored my Jeep 6 years ago and replaced the ball joints, tie rod ends, bushings and also bought factory shackles. I had a little wander but it is a Jeep after all. I thought everything was fine until my tires started wearing unevenly. I brought it back for a second alignment and they also adjusted the steering box. Now the steering is a little bit different than what I'm used to and after 6 months the wander is worse. A friend suggested poly bushings and heavy duty shackles. It took a lot of the wander away but when I installed them I had to pry the springs a little to get them to line up with the shackles. Sorry for the long read but I thought you might like a little background.

This is the proper way. If you read to the bottom, you'll find that the adjustment the align shop did, was at best a bandaid. And, if not done correctly can cause the steering box to lock up.
"The nut and screw adjust Worm bearing Preload and Sector shaft mesh. NOTE! The steering gear must be out of the vehicle to adjust it on all 1974 and later Saginaw rotary gear units. The earlier models can be adjusted (sector shaft preload) on vehicle. Here is the manner that GM Saginaw Division recommends how to adjust. Disconnect the pitman arm from the sector shaft, completely back off the sector shaft adjusting screw on the sector shaft cover. Center steering on the "high point" then attach an inch lb torque wrench to the steering wheel shaft, the torque required to keep the shaft moving for one complete turn should be 1/2 - 2 in lbs. If the torque is not within these limits, loosen the thrust bearing locknut or tighten valve sleeve adjuster plug to bring the preload within limits. Tighten the thrust bearing locknut and recheck preload. Slowly rotate the steering shaft several times, then center the steering on high point. Now, turn the sector shaft adjusting screw until a steering shaft torque of 3 - 6 in lbs more is required to move the worm through the center point. Tighten the sector shaft locknut to 35 ft lbs and recheck the sector mesh adjustment. Total steering gear preload should be 14 in lbs or less. Install the pitman arm and replace back in vehicle. To try and adjust the sector shaft screw without doing the preceding will DAMAGE the steering gear. Most of the play is not in the sector shaft adjustment, it is the spool valve"

I just fixed this on my Dad's CJ5. Loosen up the U-bolts on the axle/spring. Using a high lift jack, porta power, 2x4, etc, move the spring over to where its back in line where it should be. Tighten up the U-bolts... Done.

But that shouldn't have anything to do with the springs would it?

Lugnut,

I'm just glad you were wearing clothes when you took that first shot

My CJ5 does the same thing on the passenger side. I replaced the shackle mount, and the frame area is straight, but it still has that "lean" like yours. Next on my project list is to replace the springs on all four corners with Old Man Emu, so at that time maybe I'll sort out the issue.

I'll be curious as to what others have to say about the possible cause!

Edit: ate dinner, came back and posted this comment and never saw all of the new responses.

Thanks, it's worth a try

No It wouldn't. Go back and read what I added in quotation marks.
