Bent U bolt plate/axle saddle and twistes leaf spring?

Hey thanks in advance for the help. I was looking at my passenger side spring (shackle looks slanted) and noticed the u bolt plate may be bent up toward the center of the jeep slightly. This has twisted the spring and maybe caused the shackle to be slanted.

Has anyone saw this before? I'm guessing I need a new plate, sway bar, axle saddle....etc

Here are some pics you may be able to see that the spring is twisting. I read somewhere that this may be caused by spinning the wheel without positive traction?

Put the front end of the Jeep on jackstands, loosen the spring eye/shackle bolts and ubolts, re-align everything making sure the center pin is in place and in good shape. Tighten up the ubolts (follow an "X" pattern) to spec. Put it back on the ground and then tighten up the spring eye and shackle bolts.

Thats odd for stock chassis jeep. Lift shackles can cause something similar, but typically they lean to the driver side due to the track bar pulling on the Axle due to the lift. The spring looks to be seated in the perch good, and looks level at the perch. Its like the spring itself is twisted at or close to the front eyelet. The fact the spring plate is tilted could be caused by someone over tightening one side and not tightening the u-bolts evenly. The bushings look to be worn out bad, might try a set of new poly shackle bushings, they are 11.99 a set through Morris 4x4, they have specific bushing for stock shackles or aftermarket shackles too. Takes one set of four bushings per shackle, plus you will get new bolt sleeves. You would reuse your shackle bolts and shackle plates.

looking at the pics for a second time, it looks like both shackles are leaning the same direction. I would just about put money on the shackle bushings being shot. Causing it to lay over to one side.

Good eye the drivers side isn't as bad as the passenger. Those shackles are brand new put them on yesterday. Had the same problem but worse with the old shackles

Right angle grinder will cut off the old u bolts, or heat the nuts if you need to re-use the ubolts, but if it was mine, I would cut them off and replace them with new ones, if they are the original ones.

Did you replace the shackle plates and Bushings, or just one ?

Has it ever been hit in the front on the drivers side in the past ? You said the shackles were new, did you mean the shackles bushings were new or just the shackle side plates were replaced ?

I ordered 2 shackle kits from quadratec had bushings, plates, bolts, sleeves and everything. Replaced both front shackles.

I will definitely order some new U bolts I got a hugh rachet that can bust anything loose. This thing is unbelievable

Ahh ok. The only other thing I can think would cause that lean like that, is if hit took a hard hit in the drivers side front wheel at some point, or if the axle tube is bent up on the pass. side.

Did you notice if the leaf spring was still twisted on the end, when the shackle was removed from it ? That could mean the main leaf is twisted, and that can definitely cause that. You never know what a previous owner may have done with it. Believe me. lol

I found all kinds of things to fix on mine after close inspection at home. Bought mine in Feb this year, since Feb, I have replaced all the rubber bushings underneath with polyurethane bushings, I mean all the suspension bushings, sway bar and track bar bushings, Torque arm bushings, transmission mount, motor mounts and body mount bushings, all polyurethane. Rebuilt the spring packs, new hub bearings, new ball joints, new soft top, new bikini top, new rock crawler bumpers, new winch, new passengers side Knuckle, new tie rod ends, new rear brakes(fronts were already new, with new rotors). It already had a new radiator, starter and alternator. I also put on a Carr light bar and 2 - 6 inch KC lights, Rugged ridge console, Jeep Floor mats, subs and amp. Waiting for UPS to bring my new hi lift jack, and fairlead isolator for my new winch. Nex is the motor.. lol .

Yes, you could say that. But, having all the right tools and knowledge sure helps. Plus a Bigg A$$ barn with concrete floors to work in, makes it much easier on an old man like me.LOL.

I think I would try Non Rubicon's suggestion about loosening everything on the springs and retighten using the method he stated, then see how it looks, make sure to check the leaf spring center pins to see if they are broken, centered correctly in the perch, etc. I have seen some center bolts that have a smaller head on them, which can cause movement within the perch if there is not a tight proper fit. Whether it would be enough to make those shackles lean like that, I doubt it. But, its worth checking while you in are there anyway.
