This! ... This is why I joined the forum, You were 100% right. They're not bushings as I first suspected and they have now received a much needed service as per your video. Sadly, it didn't get rid of my death knock, but was much needed none the less. Great info! That said, everything SEEMS tight really, so I suspect I may have a bad shock? Gonna try switching them sides to see if the knocking moves... Again, thanks for the epic advise!
