Hey guys, I'm just about to start my Powerflex bushing install along with some Madness strut plates. The only two questions I have now is, do i need to order a new circle clip that holds in the drive shaft once I pop the old one out? And, can I only pop the inside of the shaft, enough play to leave the hub side still attached? I have both BMW tools to remove/install the control arm and press in/out the bushings, hence, I'm not dropping the sub frame.
