Re: popping noise????
Whats happening is the first coil or two are collapsing on each other. I had this happen with my Intrax springs. This makes a clunking or popping noise. Its not uncommon. Some spring manufacturers will actually send rubber insulators to slide on the first coil rings. Go to Home Depot and pick up some rubber hose. Should take care of it. But first make sure the strut mount nuts are tight.
