So after getting the clunk fixed during the brakes service a little while ago, I found out I needed an alignment. After doing the alignment, I found out the uniball in my UCAs had some play and was soon due to be replaced (1.5 years of use, 1 year with ICON's UCA caps). I got a local shop to install ICON's Delta Joint into the UCAs. So far things are good, no complaints. Time will tell how well this new "sealed" setup lasts.
