Or it could be a third problem: The coilovers and the Blues are working fine and the ride is just how it is going to be forever. With coil-overs like you have there is much less spring travel distance therefore they have more work to do in less space... THEREFORE they will not ride well no matter what. Coilovers will always give you a harsh ride and will be squeaky, noisy and clangy... thats their nature.

I think the blues are just fine. I have them and I dont think they will blow after only 2 years.
