Could be worn strub boots or a broken spring... Doing some maintenance on my BC's and found out I have a broken spring AND my boots are completely worn out after 2 years... Not impressed... My MEGANs were shit, and died a hastened slow death, but at least nothing broke outright on them...Thanks for this. I am hearing a clunking noise in the rear going over small bumps and can't figure out what it would be from. I'm wondering if this could be from not adjusting the preload?
