Issue after IRO install

Installed the IRO 3" probably a month ago. After a little over 100 miles i made sure everything was still tight and got an alignment. After the alignment i brought it home and made sure everything was tight again. Shortly after that i took the jeep to a little spot down the road to get her muddy. As soon as the jeep touched dirt it started clunking in the front. Back out on pavement it stopped. As the days went on it started doing it on pavement. Again i crawled under to make sure everything was tight. Sure enough, it was.

I had my brother crawl under and check everything while i moved the jeep around. What he found was the track bar moving on the frame end of it. The track bar is 100% tight and won't tighten at all, even with a impact gun.

How can i get this darn thing to stop moving on the bolt so this clunking stops?

The hole is probably wallowed. Drill out to a larger size or washer weld it.

its a brand new adjustable track bar from IRO. The bar is moving on the bolt. How would welding a washer in help anything?

It's not the bar its the brackets the bar mounts to that's what slaink8 suggesting....pull the bar off that side and look at the holes the bolt goes through chances are they are not circular anymore. If they are not you can weld the proper size washers on the outside of the brackets to stop the bolt from clunking. Or drill the hole out a size bigger and get a bigger bolt if you don't have access to a welder.

It's not the bolt moving though. It's the bar itself moving on the bolt

Bushing deflection? You sure? Did you use an aftermarket or OE bolt? How much slop with the bolt in the sleeve?

the OE bolt. the original. i thought they would've sent new hardware....but i thought wrong. i honestly don't know how much it moves. i can't move the jeep and look by myself. but i can lightly rock the jeep by grabbing the roof rack and it'll knock.

If its the bolt, why can't you simply remove the OE bolt, and try a larger size? You'll have to drill out the welded nut to do this. If its a stock replacement, I don't understand why there is slop in the sleeve, as you're suggesting is the issue. Did you contact IRO? And why don't you lay underneath your jeep and your buddy can turn the wheel? See for yourself what is going on.

I was trying to figure it out without contacting IRO. I'm kind of stubborn like that I guess. I crawled under it today and not a single thing moved. Not even the track bar like I had stated it was before. BUT, when I was taking it off the jack stands, one side compressed and the spring made a noise that sounded like it seated (was definitely already seated before). Put it on the ground, grabbed the rack and rocked it. No noise. Awesome right? WRONG! Now the noise is on slight bumps, like seams in the pavement, or sharp turns left and right.

Check the clearance between the track bar and the differential. IRO's track bars lacks the bend for differential clearance that your OEM bar had. Not to long ago there was a thread on here about an IRO track bar hitting the differential and clunking going over bumps. You will find it in the thread linked below, read post #7. Check post #11 for some pictures of the difference in the bends. http://www.jeepforum.com/forum/f310/...ength-1570680/

FWIW, I found that my IRO adj track bar had movement on the frame end, and I could see the bushings move. I put in the KOR super-ultra-mega-whatever bushings, and I find the Jeep is more solid up front. I was having a hard time keeping grease in the bushings though, and was getting some stick-slip noises from the bushings -- the fit is so tight with the parts that when you grease it and put it together, it just wipes off the grease. But I've had it apart a few times now and it seems better, maybe it's settling in.

I think the IRO bushings are a bit too soft.

Good luck,
Pete

Yes, I have firmer track bar bushings that require lube often. Or it squeaks a lot.

Might be the track bar squeaking.

I think it is the front sway bar bushings, check them and make sure that they are greased very well
