Not sure if it's considered a bushing or what, so I'll let the photo speak for itself. This is on an 09 Impreza 2.5GT, which is supposed to be equivalent to a 2008 WRX auto:
Driver's side has that same type of split in the bushing(?). The car has 130k on it, but I haven't really noticed any handling problems lately, only some occasional light popping noise from that that area over small bumps at low speed.
Any advice on how serious this is, and what to replace them with? Thanks
