Suspension problems on purchased YJ

Posted this on some local forums, but figured it wouldn't hurt to get more insight.

Basically, picked up a YJ last weekend, and it rides like a toaster. I'm no expert, but I think something is seriously borked with the suspension. Here are a couple pictures of the setup; I'm hoping some of y'all have more experience with this stuff than I do and can't point out things that don't look right:

Front shackles and knuckle

Bushings look toast:

About 1" of play on what I assume is the bumpstop:

Rear:

It looks like the rear shackle can't be accomplishing anything other than smashing down on the top of the leaf, mangling itself and destroying bushing:

The front knuckle is facing outward, but from other pictures, I think that should be facing down? Only been at this for a short time, so feel free to take your shots at me and my back/neck destroying ride! Let me know if more pictures would help diagnosis; album is at http://rezk0.imgur.com/yj/.

Thanks!

I don't have any experience with them, but those are revolver shackles. The ride is rough because the spring doesn't have much room to compress like it does with a normal or boom shackle. Or so I would imagine. Others will be around to help you more.

x2 I dont have experience with them but from what I can see, it looks like youre missing the nylon blocks in the front revolvers. Not positive on that, but something is definitely wrong there.

The bushings are definitely gone to another land, no doubt about it.

You may want to cut that tie wrap that is holding the brake line to the shock.
Eventually it will wear a hole in the brake line.
As others have said you are missing the blocks for the revolvers. It is a pretty common thing to happen.
Replace the blocks or get new shackles.

Thats only the issue in the front, it looks like the blocks are there in the rear ones but his military wrap is sitting against the frame

I got more pictures and found that both front and one of the rear are missing.

Would it make sense to start by replacing the cushion blocks and all the bushings? Or should I just bite the bullet and replace the shackles completely, go with polyurethane bushings and maybe even replace springs. If I have to spend a few hours fixing it, I want to make sure I fix it right.

Youll have to either replace the blocks and bushings or replace the shackles all together. You shouldnt have to replace the springs unless theres something wrong with them that I dont see

I will send you my booms for your revolvers and since your new and need help, I will even let you pay for the shipping both ways.

Its hard to tell on my phone, but it does look like your springs are contacting the frame which will knock fillings out.

Oh and a few pics wont load for me, but if you still have track bars, ditch them as fast as you can!

Cheers

Edit: whoa so some more pics loaded for me. You have a lot going on there. Can you get some pics of the jeep from the side? How much tire clearancedo you have? There is like, zero, room for uptravel with the way that's bumpstopped. I imagine a small dip in the road would cause that to contact, which would be very jarring.

I'm thinking you don't have nearly enough lift for whatever size tires are on there and the PO did that to prevent the tires from shredding the fenders while driving.

Welcome to owning a YJ! I can't tell you it will be easy, just that it will be worth it!

Yeah, if you lift one side off the dirt, you can see how much of a dent the springs have made in the frame.

I can jump on the bumper and cause the bumpstop to hit on the driver's side. The passenger side doesn't have a bumpstop.

Got a couple pictures from the side. It's only sitting on 30" tires right now:

Thanks! Lot better response here than I've seen from a lot of jeep folks, which has generally been, "It's a jeep, deal with it." Took it to a local shop to look at doing a SOA lift, replacing shackles / springs and installing my Ford 8.8 rear axle and look like it's going to run me about $3000 after SYE / driveshaft / etc. I am kind of thinking do that route. Cost of regearing caught me offguard, so need to do more research there.

I think the front can be fixed by replacing the blocks and bushings but Im still stumped on whats going on in the rear. You could also remove the bump stop extenders for some more travel

It looks like you have 2" BDS springs..

I'd say order 1" BDS Boomerangs when you call to get new bushings, and replace everything at once. The revolvers are doing more harm than good.

Also, you're missing a body mount bolt above the driver rear shackle
