I'm at 45,000 miles too (hit it today), and I have that problem as well. Last time I used Gummi-Pflege, and it worked like a charm, but the noises came back after a few weeks. I applied some more today, but not as painstakingly as before, and the noises didn't disappear. That made me very mad. I hate touching that stuff. I guess it's time to find that Kent stuff--tomorrow! I'm getting tired of this. I wonder if I should get the seals replaced anyway.
