did you buy just a bearing or did get whole adj -idler-bearing ?
I swapped out complete belt tensioner assy,Idler bearing looked and felt to be in good shape ?? Maybe I should swap out bearing in idler pulley ??? thanks Steve
yes get the complete idler pulley. you need some special tools to change the bearing and its really easy to damage the new bearing changing it out.
Any luck on replacing the tensioner pulley. I have the same bearing rattle on cold starts!
Have yet to swap out Idler bearing, changed belt again, good to go for another month of quiet operatiobn. W.T.F
cold start rattle

Ok so by replacing the belt you got the noise to stop.
You should read my original post from 11-09....We may have different issues ???
!0-4 your probably right. Just trying to trouble shoot. Appreciate the help...
