I have a stock '18 Screw with 26K miles. Tire pressure is 35-38 PSI on original KO2s. When traveling over small abrupt bumps on pavement (probably happens off-road too, just never noticed it), think a minor pot hole or a manhole cover, at slow speeds (5-20 mph) I hear a noticeable clunk/thump. I believe it's coming from the front end but I am not totally sure. It sounds sort of metallic, like a loose part or clanging. It doesn't seem to happen at faster speeds or on larger bumps, although I suppose road noise may be enough to block those out. This just sticks out because the sound doesn't at all correlate to how little the bump is (sounds abnormally loud). Any thoughts about whether this is normal for Raptors or could represent a problem?
