I've been chasing an intermittent clunk in the rear end and I either found the culprit or I found an unrelated problem; at the very least, my drivers side rear diff bushing (OEM) has a big gap in it where the rubber has given up. Apparently this is fairly common, based on what I have read. Now the question is, short of replacing the entire subframe to get new OEM bushings, what is the least-NVH adding option to rectify this? This is an 80/20 street/track car and I'm fairly anal about added NVH, so I am trying to assess my options. Looks like I could go the BMR BK049 or Steeda equivalent poly lockout route, but that seems to add a noticeable amount of NVH, especially with me having a 3.73 rear end. Another option would be the Whiteline KDT933s, which are new bushings entirely and therefore have a higher installation overhead/cost, but they are softer and theoretically more compliant and less likely to transmit NVH than the poly lockout options.
Are there any other options I'm not thinking of? And regardless of which route I go, should I be looking at the BMR bolt/hardware upgrade as well?
