I have a Weslo Cardioglide - I think it's a WLMC0034? I noticed the pivot rod above the cylander that is next to the seat shifts back and forth - left to right. I originally bought the Cardioglide used several years ago, and am not sure if it always did this. In any event, I'm concerned that one of the dome caps/axle caps on the side of a link arm could pop off, as I've seen this happen on other Cardioglides - and then the machine would be broken. What is the best way to fix this? Is there a way to tighten the axle caps? Or, if a cap falls off, do I just buy a replacement and pound that on with a rubber mallet? Any suggestions?
