My main concern is a woowoowoo howling noise that seems to be coming from everywhere. I guess I'll have to get someone else to drive while I hang of the bottom like Robert DeNiro in Cape Fear.
I verified, by slapping some packing tape on the driver's front tire, that the "woos" occur at the same rate as tire rotation (which means the hours I spent cursing over the u-joints in the rear CV driveshaft were wasted).
The noise happens at all speeds above 15mph or so, and doesn't change pitch. It does come and go somewhat and seems like it might get louder when braking, but it doesn't ever really go away. From all I have read, this means that it is either a wheel bearing or the carrier bearing. If there is anything else that would account for constant wheel speed noise, please let me know.
I'm in the process of eliminating the front wheel bearings from the equation, which leaves the rear axle shaft bearings or the carrier bearing. From my searching, the only way to check the axle shaft bearings is to pull the shafts and visually inspect the shafts and bearings. Is there any other way to find out? (I've got synth in there I'd rather not dump unless I have to). One thing I did notice, is that I couldn't hear the howl from the outside when driving by a wall with windows open (which, unfortunately makes me think it may be the diff)
Also, I've read that the carrier bearing will sound worse in reverse .. How about if the rear is on jackstands though? Will it still make noise, or does it need to be under load?
