I'm using RG coilovers, I dont think it's famous in the US, but the general design of the coilover is the same as all coilovers

I hear squeaks (like old barn doors) when there is load on my front driver side coil.

I suspect that the noise is due to the coil rubbing against the mounting.There is no problem with the other sides.

I've recently changed all my control arms and both the tierod-ends.

Anyone with similar experience care to share some info? What would be the best remedy to remove the noise?

I've had two sets of COs and two sets of spring/damper combo. Both coilover setups make noise. One clunked. The squeaks came mostly from the front. My sways bars make noise too.

I live with it.
