I always get good advice on this site and once again am trying to take advantage of the knowledge available. I had installed new coil springs, upper / lower control arms, and whatever else came with the all in one kit. I have had it back to a couple of shops trying to get a clunking sound fixed. 2 of the 3 shops lubed it and sent me on my way. The last shop (which seems pretty good) thinks it is my coil springs moving on the perches and causing a "popping" sound. He suggests the spring be removed and the ends "flattened" (he thinks the after-market spring is rounded on the end and needs be grinded flat). Has anybody else had this problem and/or have any suggestions to fix. The car seems to handle good - just makes noise. Thanks.
