knever3 Posted October 27 Share Posted October 27 My front coil spring mounts are rotting out, above the rubber isolator. I can't find a replacement for them, just the bump stop cup. Are these replaceable, or are they welded to the body? I thought I had a broken front right spring because the right front tire rubs on turns, it didn't when I first got these tires. They either sagged just enough, but it looks like I need to replace the mounts, but possibly the springs as well. I hate that they are all rusty, so I would like to buy some OME coils while I'm at it, but they are pricy. I want a SOFT ride, I have JKS adjustable uppers and lowers and a 3" lift, but when I look at the truck I don't think I have any lift in the front anymore because of the sag. Tell me what you think I should do, and what to buy. Link to comment Share on other sites More sharing options...
GonzoTheGreat Posted October 27 Share Posted October 27 Those don't look too bad. I could be wrong, but from these photos it doesn't look structural. I think if you pry the rubbers off, you'll find good, clean steel underneath, and you can just clean up and repaint any bits around there that were rusty. As for the rubbing, you said you have a 3" lift and it's the passenger side that is rubbing? Do you still have the stock track bar? If the track bar is too short, it's gonna pull the whole axle to the driver's side. Try putting the wheels straight, and measure the distance from frame to tire. It should be equal on both sides if the axle is centered. Link to comment Share on other sites More sharing options...
ThatJeepGuy Posted October 27 Share Posted October 27 Honestly the coil spring looks broken at the top in the first photo you have. Like the coil itself doesn't end at a full thickness like it tapers down to flat - and that flat thin section has rusted away. Putting your jeep up on some tall stands supporting your frame from behind the control arm mounts, maybe taking the wheels/tires off as well could relax things enough for the front axle to droop out and you could maybe wiggle on those coils to see the condition a little better.

knever3 Posted October 27 Author Share Posted October 27 I am surprised these coil springs have went bad, but it's been about 13 years since I bought them, time flies! I guess I will buy some OME 2930 coils and some new rubber spring isolators and see where that puts me. My adjustable track bar tie rod end is worn out, I can't find any replacement tie rod end for it. I think it was a Superlift? No real brand name, I just knew the tie rod end was bad, I guess I will have to buy a better adjustable track bar. If anyone wants to chime in on any other ideas, or which adjustable track bar I should go with, feel free. I have the OME coils, Moog spring isolators, and a BDS adjustable track bar in my Amazon cart, another $500, sigh. Link to comment Share on other sites More sharing options...

Gojira94 Posted October 28 Share Posted October 28 These? It's what I replaced mine with. Steel core inside. Also, I've noticed the holes under the coil/ module assembly can allow water to enter the void above the spring/ cushion. Only way to drain trapped water is to remove the bumpstop/ cup that's screwed into the middle on the bottom side. Later XJs have the bumpstop cup welded on. Every one I come across in the boneyard has a wet slimy grimy mess under the expansion tank and open holes with water surely inside that void. If I owned one of those later XJs I'd get in there, drain it, flush it, hose it with rust converter. I sealed all the topside holes on my MJ to prevent water getting inside. My bumpstops were screw-in, but have been replaced with ACOS. At least with the earlier XJs and the MJ you can pull the bumpstops once in a while and drain any water.

knever3 Posted October 28 Author Share Posted October 28 Good info here, I will need to investigate this further when I'm in there! Yes, I need those rubber isolators as well, or a similar brand. Link to comment Share on other sites More sharing options...
knever3 Posted 4 hours ago Author Share Posted 4 hours ago Ok, update time. I bought some OME 2930 coils to replace my sagged "Motion Offroad" 3" springs. I don't even know who made them at the time. I removed the springs and the upper coil spring mount was torn apart, that's what all that metal was in the pictures above, springs weren't broken. The OME coils are about 2" SHORTER than my current coil springs. I didn't even need to use coil spring clamps to put them in. They are a bit bigger in overall diameter, but the steel is a smaller diameter, so I am certain I will need to buy some coil spring spacers to my sinigrin. The Dana 30 upper control mount bushings were bad, by the way, K3166 is the correct part number no matter what you may read on the internet. I am in the process of getting it back on the wheels so I can measure how much of a spacer I'm going to need, but then I can't use the rubber spring isolators, that would be a waste of money. I spent $250 on the springs when in reality I could have bought just some basic spring spacers. I guess you don't know until you're in there. My JKS upper and lower control arm bushings are shot, so they will warranty them, but I may have to send them mine, wait a week or two, then get some replacements. That would be a serious inconvenience not to have a truck for that long. I bought some new sway bar bushings for my 28mm sway bar, but the main clunk was from the upper control arm bushings in the axle, I'm sure every other bushing was taking a beating to add to the noise. I guess we'll wait and see tonight where it ends up, then order some spacers to take the place of the rubber isolators. It seems kind of strange, the OEM uses a nice rubber spacer impregnated with steel for a quiet ride, then the aftermarket just uses some hard rubber/plastic to replace them with. I am surprised that someone doesn't make a spacer with some soft stuff to go to the body. Anyone with some advice from here would be helpful. Thanks!

It only rubbed on the passenger side bumper end, but when I took the sway bar off to make sure the body bushings were making noise it rubbed on both because of body roll. I forgot to mention I need new bump stop cups, and I didn't order any... Link to comment Share on other sites More sharing options...
