Has anyone experienced this with Icon??

I have Icon 2.0 shocks installed along with an Icon RCT option 2 leafs in the back. The issue I’m having is on the passenger side of the truck the shock is moving up and down in the shock mount bucket. It’s not compressing like the other side. It’s just bouncing on the bushings.

I removed it and reinstalled and same thing is happening. The top nut is torqued all the way down so it’s not loose at all. The truck obviously is noticeably way stiffer passenger rear.

what would cause this? The shock looks fine. No leaks or anything

 

Here is a video of what the shock is doing. It looks like I could just tighten down that top nut but it’s all the way tight. There is no more threads left.

Is there supposed to be another washer/collar above the top of the shock? You're right it looks like it's just flexing through the top of that bushing.

 

The lower bushing and/or washer may be toast:



That or the threaded shaft stem has pulled out of the shock body somehow.

 

No it’s installed exactly the way the instructions say. Bushings and washers are correct

 

how would I be able to tell is the shaft stem has pulled out of the shock body? When I removed it and reinstalled it the shock looked fine. Is there a way to check for that? My mechanical skills are relatively basic lol

 

^You'd have to measure and compare against the other side. But if you've removed it and the shaft stem looked fine, then it's unlikely to be an issue.

Make sure the lower washer is sitting on this shoulder, not against the top of the shock:



Do the top and bottom bushings look the same?

 

The bushings are identical and it’s sitting on the shoulder as you described. I’m at a loss on this one. Iv searched and searched and have not seen this issue posted by anyone else. I guess I’ll email Icon and see what they say. My truck is drivable like this but it feels terrible in the back as you can imagine.

 

It definitely seems like that should tighten down more.
Did you check to see if there might be a damaged thread that is preventing the nut from tightening down all the way?
(try threading the nut by itself down the shock stem to see if it reaches the bottom of the threads)

 

Buy a bunch of standard washers from the hardware store and insert them between the nut and the big washer. That'll enable you to tighten down the nut and squeeze the bushing properly without bottoming on the threads.

 

I think I figured out what the problem is! The max lift the icon 2.0s can handle in the back is about 3”. I just measured from the top of my axel tube to the bottom of the frame and I’m at 12”. Stock Tacoma is 8” so I have 4” of lift on the side with the bad shock. The other side is 11 3/16th so I think the shock working correctly on the driver side can handle that. What I suspect is going on is some reason the icon RXT option 2 is giving me 4” of lift on my passenger side. How is that even possible? I have a 200lb camper shell on the truck too!

Before I go tearing into things and insight on this would be awesome.

 

Photos... we need a bunch of photos, of the entire setup.

Have you tried removing the shock and compressing it by hand? It seems like it's seized up.

 

Anything specific?

 

No. This would not cause the issue you’ve posted in your video.

what will happen is that the shock will limit your down travel. With new leaf springs, you likely can have the rear axle flex more and move more distance, increasing your travel. The rear shocks can only travel a fixed distance out and have a minimum compressed length so when bolted on, they will define what travel you have now.

 

Remove the shock and see if you can compress it by hand

 

Here is a video I just through on YouTube. I’m terrible with pictures

Show a picture of the other side to compare. Looks like that nut isn't all the way tight. Either your missing a washer/ rubber bumper or the threads are damaged so you can't tighten it down enough.

 

that’s the other side. The instructions say to tighten it flush with the bolt so it’s already tighter than it should be. I can’t tighten that nut anymore that’s as far as it goes. Nothing is across threaded. Both sides are installed the exact same. At this point I think icon sent me a bad shock. I’m going to pull it out again Tuesday and see if I can compress it. I do know they can be very hard to compress though so it’s hard to tell if it’s bad. None of this makes any sense to me

 

Any chance those rubber bushings are two different designs and you used the same two of one style on the good side and the bad side has the leftover size?

 

Are you using an allen key to stop the top of the shock from spinning? You’ll never get it tight

Use an allen key and tighten the top bolt with a open end wrench
