Suspension issues

Ok so I have had this jeep for two years now it is my wife's daily driver. That being said I don't drive it on a daily basis and my wife is just used to it or she thinks its just a "jeep sound, smell or something and dose not always tell me what is changing. I have done a lot of work to it including replacing the gas tank that had a crack in it and more gremlins are stating to come out. I drove it to work today and noticed there was a sound like the axle was hitting the frame on large bumps. I has a really rough ride to begin with but it seems like its getting worse. When in got to work I looked into this "bottoming out noise and found the top of the rear diff is hitting the gas tank. Thats why I had a crack before! Anyways now I am trying to figure out what I have for a lift the guy I bought it from had no idea what it was ( I bought it lifted). I know there is at least a 3" body lift but as for the suspension I have no idea. I like the ride height and would like to keep it. How would you guys go about fixing this? Here are some pics I will try and get some better ones in the morning but I figure I would ask. Thanks in advance for the help.

How much you want to spend? As far as hitting and cracking the tank, your tank skid plate should be taking the hit, many dimple the tank for more room. Which brings up the first problem, why is it hitting the tank with the stock D35 rear end? This sometimes happens with a larger 8.8 rear end, or for those who stretch their ride. I wonder if your axle has bent the center pin on the springs and moved rearward. You could add a 1" shackle lift to the rear for more room. I'm not a fan of body lifts over 1" but it's not my jeep. If it were, with the tires you are running I'd go a 1" body lift, 2.5" spring lift, and .5" shackle lift. If you want some loving buy your wife Old Man Emu 2.5" springs.

?

Not sure what axle is in there I will check in the morning. What is the likely hood that the axle has slipped back and bent the center pins? What is the the best option for new springs on a budget?

I think of the budget lifts the 'zone' 2" lift gets good reviews. everything for around $500. the Old Man Emu are praised for best ride, but they require using their bushings so around $500 for springs an bushings then you have to get shocks an maybe hardware. I went with pro comp 2.5" an it rides better than the flat worn out 20 year old stock springs, but rides about like a HD truck. It might improve with better shocks. If you price kits look at what all comes with the kit. If you have to buy U bolts they add up.

Ok as for the shocks they are only 2 years old they did not help. I have 33x12.5r15 on there now would putting a 2.5 lift clear those tires? Also I would love to take this out on some trails due to the concerns with the suspension from the start I have avoided it. I found rubicon express 4" for around 850 on Amazon. Is rubicon express good have not heard a lot about.

You have a D35 in the rear, and your springs don't look cheap. If you can find out what brand you may get a replacement set if they have sagged. They look like they could be RE. As far as your axle, it's hard to tell in the photo, but it looks like your U bolts don't point straight down, it looks like the ends point towards the front, which could mean it's not centered over the center pin. It also seems you have a shim, and maybe even a stacked shim. Again the photo isn't clear but it seems like two pieces. I wonder if they bolted the shims through the center pin or just laid them on top.

Are you running an SYE? Your DS looks to be pointing right at the TC output. That would explain the U bolts tilting forward if the shims are pretty steep.

Is that a mark on the top of your leaf wrap from banging into that bolt head under the frame?

X2, you already have lift springs. I'd take it apart and check the center pins, your u bolts are pretty rusty I'd get replacements and just cut them off.
also, you said the shocks are new, are they the right length for the lift? they could be bottoming out.

Ok I do have an SYE and the axle dose seem to point up towards the TC. The shims are in a wedge shape not sure if thats all the problem is for that?

Yes that is what it looks like I need another set of eyes to see if it is hitting but all the signs are there.

The shocks I got are sky jacker they are rated for lifts from 4" to 6" not sure if that is too long since I don't know how much spring lift I have.

Your missing the bumpstop extenders and maybe even the bumpstops as well. Below is just one example of what i mean.. the part fits in at the u-bolts. Also is there some sort of odd bracket for the front steering, hard to tell in the picture.

It looks like the spring eye is hitting the bolt that attaches the bumper to the frame. I agree with 4Jeepn, you need bump stops or extensions or even both.

Yeah it is missing bump stops. The bracket on the front is for the SJ steering stabilizer.

I don't think you have 4" of lift, so your shocks may be hitting bottom and the bolt is hitting the spring in the rear, the best thing maybe longer Boomerang Shackles in the rear, Bump Stops and maybe a new set of Gas Shocks for 2" to 4" lift. Just my 2 cents.

I realize this thread is half a year old, and I hope the OP got his wife's jeep's issues resolved. (And I am OH so familiar with being told nothing about the "sounds and smells" of the wife's vehicle, then getting in it, for a short run and wondering "WTF was THAT I just heard?" Hint: her '95 Subaru Outback had an appetite for rear wheel bearings--hired it done, due to the hydraulic press required--$400. per bearing [Parts and Labor] FOUR TIMES--the first one under factory warranty, and the last one was also REDONE, for FREE, from indep. mechanic, because a bad bearing failed within 3,000 miles. Still, that's $1,200. for WHEEL BEARINGS).

ANYWAY, enough (from me) of the "Automotive Marriage Counseling" (I'm not actually married, anyway--just 30 years of "duty.").

MY QUESTION:
WHY are the "Old Man Emu" leaf springs, for the YJ, considered the best riding? I am contemplating buying an '88 YJ (with '99 Cherokee AX-15 and transfer case) but the front leafs are "sacked" and sitting on the jounce bumpers/bump stops.

I don't mind spending the money, to get a SUPERIOR ride, at STOCK HEIGHT, with STOCK TIRES. I will be doing some (non-commercial) snow plowing (Western, 6'6", hyd. angle), fire-roading/hayfield cruising, and grocery getting. I've had back surgery, and want the best ride possible in a stock YJ (and yes, I do realize it's a Jeep, and "best ride" is still relative to that fact, given the leaf springs, etc....) I DON'T MIND spending the extra dollars, but I'd like to know what makes "Old Man Emu" leaf springs have superior ride quality?

Thanks much.
