I replaced all four shocks last year with Konis. Also replaced the rear caps above the shocks. Just recently I am hearing a rattle/metallic type of sound when I hit a bump in the road. Sometimes soft, sometimes loud but it is pretty consistent. Put it up on lift and the only thing that was loose was a hose of some sort that had a plastic clip on holder that went into a unit next to the rear end unit (sorry about my terms am not that technical). The noise stopped for a bit but started up again -- have to check the hose again if it is loose. However, it does not seem logical that a rubber hose would make that kind of noise. Any thoughts on what it might be? Any thing I can do to check on the noise?
