well, i'm the first to admit that i am mechanically blonde, & 2 guys did NOT hear the noise i heard! finally, i had some one drive it while i was passenger, & snapped my finges every time i heard the noise. FINALLY, he heard it, & pulled over to invesigate further. he did not know for sure what it was, but due to the area where it seemed to be coming from, he suggested i have it looked at. i called dealership, & spoke to shop foreman, & he said it COULD be timing tensioner, BUT could be.....
SYMPTOMS:
under load, between 2800-3200RPM (5 speed) heard faint rattle, especially 2nd gear.
since car was in shop for wreck repair, (almost 3 months) i was very skepticle, since the "mechanic" failed to plug spark plug wires all the way in & it ran poorly & HE couldn't figure out why???? ended up taking it to dealer for diagnosis.....
so, hope that helps, i can only relay what i hear & feel, no mechanical ability or vocabulary! just really glad i listened to my intuition & had it checked before xtended warranty was up!
about the dog bone, don't suppose you know a suby part #??
