For those that have lowered their cars, has anyone had problems with this bearing? It is a black plastic bearing that sits on top of the spring seat and rests against the under-side of the wheel-well. I lowered my car with Ground-Control Coil-overs and this bearing seems to squeek fairly frequently. If I clean the road grime off of it, the squeeze goes away but still comes back fairly quickly. I have also had to replace cracked bearings (cheap plastic) in the past. Anyone else run across this and know of better bearings to use or some other solutions to help prevent these sqeeks? I try to clean my wheel wells when I wash my car to try and help, but not much luck.
