Hey guys, I've been searching for about a half hour in here trying to find anyone who has installed Zurk fittings into the control arms. I installed poly bushings a year ago and they squeak bad now and I didn't want to dismantle everything to grease them so instead I thought of installing zurk fittings to make it easier.
Basically I'm wondering if anyone has done this and if so do you drill thru the bushing to the center or just thru the control arm housing stopping at the bushing?
Or i will take any input that will help stop the squeak!

Thanks for the help
