My 2005 Honda Pilot has 125k miles and has developed an occasional clunking sound from the rear suspension. It seems to happen around sharp turns or when the rear suspension is unloaded, like hopping over railroad tracks, or when going over short/sharp bumps. It is inconsistent, in that it does not happen all the time. I was checking and checking for loose parts for months and tugging on suspension parts like arms, links, sway bar, etc. I find nothing loose or clunking or showing signs of loose connections.
Today, I was checking with the car on jack stands and found the “hubs” or sheetmetal covers that the CV boots are clamped to are loose at the differential. I believe this is the sound of the noise. They rotate with the rear wheels and kind of clunk around with some manual pressure applied.
Are they a typical source of trouble?
Are they easy to replace?
Are they nothing to worry about or is this a precursor to the axles falling out?
