Ringing and vibration
'05 Edge 4x4, big 6
Hi all, 1st post.
Ok, I've got a ringing noise at around 25-35 mph on smooth (city) streets. When I get up to 50-55 I get a "pulsing" vibration. (Slight shudder, then smoothish, then shudder again.) Vibration seems to go away after a bit, but actually it's just probably less noticeable.
When I engage the 4wd the ringing and the vibration goes away. With that in mind I have jacked it up and checked shafts for play. left and right front shafts are tight. rear drive shaft is tight, but the smaller diameter shaft up front has some play. maybe 3/8's?
how much play should there be or could it be somwhere else?
