Good afternoon,

I just installed Heidt’s mustang 2 coil over conversion and now I have a horrible noise while trying to turn the wheel, almost like a rubbing or clicking noise. The install include new lower control arms and 2 piece shock and spring. I also replaced the tie rods just in case that was the issue. Any help would be appreciated

can we post videos on here?

Old coil was a 275# and new coil over spring is a 500#. Not sure if the new spring is to stiff. As soon as I Jack up the car the noise goes away

Have you been under the car with someone else turning the steering wheel..? This is what I would do in order to pin point the source of the sound.

In this picture the upper control arm looks very close to the spring pocket. Could this be making contact and creating the sounds you are hearing..? Also the spring looks to be curving in towards the frame..

I’ve tried. It’s very hard to pinpoint where it’s coming from. You can feeling it in the shock and a arm. Loosened both and still does it

Good eye Nova Thug. I think you nailed it. That spring looks to be rubbing against the frame. Maybe it's not correct for the application?

Could you have too much tension on the springs? Try backing off the tension collar on the bottom of the shock and see if it still makes the noise.

I would slowly disassemble one side down to the frame, inspecting each and every piece for a wear mark. There has to be something apparent.
One last thought. Are the shocks new, and rated for the 500#? Is there a large flat washer at the bottom of the spring, on top of the spring adjusting locknut? Mine is not the same brand parts so I cant compare, but it looks like something is missing. Im just guessing.

No flat washer at the bottom and a rubber grommet on top of the spring. They are new and rated at 500#. The coil over shock has the adjustable ring on it to draw it up and down

That spring should not have a curve in it. The barrel of the spring is curved away from the shock. They should both be straight with each other. Something definitely not correct. How does the upper spring pocket look, any marks?

Bob's 65 - I believe that is a thrust washer, two washers with roller bearings in the middle.

Just found your post. I have what sounds like the exact the same issue with my 66ChevII. Exact same set-up w/Viking Coil Overs. Were you able to solve this issue? Please advise. Appreciate it............. Alan
