Precor 5.17 clanks, too
I have a Precor 5.17 with a clank at the bottom of the left stride. I have struggled to find the source, but no luck. Mine is a different model than yours (epv02), but I will watch this post hoping for a solution in case it might apply to the 5.17, too. This clank is making me suicidal, but (so far) I still put in my 45 minutes 4-5 days each week.
