2.5 coilovers making noise

[Atoledo95]

Not sure what you are planning to lube.

Are you able to narrow it down to front vs rear? Sometimes the slider on a dual rate coilover (rear) can stick a little and cause some odd noises. If you are able to rock the vehicle back and forth and recreate the noise, may be worth having a friend help you locate the noise.

I’ve actually done this and hear nothing only when driving.

I’ll completely honest… I’ve had 4 sets of Radflos on other platforms… 3 of 4 clunked.

this is called the Radflo clunk. They performed well but were noisy

I hear the springs click/settle on mine sometimes, but I'd consider the shocks quiet. What you're describing are loose lower control arm bolts, I had the same issue after an alignment, drove me nuts. I figured out the 4 LCA bolts were ~20ft lbs, hardly holding it together, I was pissed. Check ALL the suspension torques, not just the shocks, you have something loose.

I would consider that but they just got installed and it was happening before that and still going after I installed the aftermarket Rockjock ones. But I will check if everything is torqued correctly.

It more of a creaking noise, when going over speed bumps and normal turns at time. Mostly coming from the rear left coilover.

Probably not what you wanna hear man but during my suspension review. Both sets of Radflos made noise.

other things to check. Have someone rock your bronco hard while you go under and look and hold certain components. Sway bar links, shocks, arms, etc.

My sway bar bushings made hecka noise under weight transfer. Needed two people shaking Bronco to find it when not driving.
My kings developed a loud squeaking from rear spring slider (Radflo also has this part). Spray it and soak it with Tri flo. That helped me a bunch.

I’m going to try this Saturday and see what I can find. I’ve pushed down every side and only the left is where I here something. I’ve talked to radflo they just asked what spring rate I had and to check the droop. But hopefully next week during the week I can go and have them check it out. I appreciate the help.
I’ll try to record the noise so everyone could take a listen.

Another item to check is your body mount bolts. It looks like the body has had some work. Good luck.

I dont know if this helps but I had a similar type of noise coming from the rear on my car with King shocks a while back.

Tried everything to diagnose but it was hard to make the sound when the car was not moving.

Upon closer inspection, I noticed that that the slider on the dual rate shock was rubbing the crap out of the shock body (picture attached). On the other side it was also rubbing but on the inside of the shock, so we could not see the marks.

Got in touch with Kings as it is under warranty, and the supplied a single rate spring instead to replace the dual rate so no more slider in the middle.

Once the new springs were installed, I was getting a different strange sound, like some keys jingling everytime I went over speed bumps. Turns out that the bumpstop was not all the way down and there was a small washer that kept going up and down making the jingling sound. This was an easy fix, just push the bumpstop all the way down.. Or Jump the car so it gets set down naturally haha.

Anyway, I just wanted to share some expiereinces in the hope that it may help you diagnose and find the issue.

Best of Luck

Which spring did king give you for the rears? I’m planning on switching from a dual rate to single but I don’t know which coil to get.
