Coil spring POP (1 Viewer)

[Alberta4x4]

Hello all,
I have been dealing with a popping noise in my suspension since September when I was elk hunting. It happens randomly like if it's under a torque. Sometimes turning, sometimes braking, sometimes accelerating and sometimes flexing. I was in some nasty terrain when I first heard it. I had it up on a lift, checked all the bushings up front with a bar and everything looked nice and tight. Changed out motor mounts with Oem from prior problems. Had my mechanic look at it yesterday and he couldn't find anything.

So last night I just asked my Dad to look under my vehicle while I moved back and forth over a large snow mound. AND AHA it looks to be the passengers front coil spring making the noise. It's an OME 2.5inch lift why in the world is this thing popping? Do the fj80s have coil spring bearings up top ? Or is the isolator possibly buggered? Hopefully one of you smart fellows will be able to add some wisdom

You’re probably missing the isolator at the top. As springs compress and extend they actually twist. It’s probably just making noise because it’s metal on metal

Okay so I took some pictures of my coils, let me know if anyone sees anything wrong. I personally don't see anything...

First 4 are the passengers last 4 are the drivers

I have the same problem with my Slinky springs. @Broski mentioned it’s an issue with some springs and he has a fix. Hopefully he’ll chime in and school us.

Idk if I’d worried about it then

Look at the spring on the inside right at frame height. It's most likely rubbing there.
My guess is you have a stock panhard bar and the the lift is pulling the axle to the the drivers side and causing the spring to rub on the bottom of the spring bucket.

In @Road Apple case the Delta control arms move the axle forward putting the springs off center off of the spring buckets and are most likely rubbing in the same spot.
In the last picture in post three you can see the horizontal piece of metal sticking out from the bottom of the frame it has a semicircle cut into it to allow clearance for the spring.
I cut that piece back flush to the frame and it solve the problem.
