I have a 94 SE with 189K miles. Changed the right front (passenger) wheel bearing due to excessive play that was causing tire wear. No noise. The 'new' bearing was used with 30K miles on it.

A month later, I am getting a hum that varies with speed. I put the front end up in the air and listened as the tires spun. The sound starts at about 25 mph. Definitely the passenger side.

No play or cogging with the replacement bearing.

Here is the question - Hard to tell if is the wheel bearing, or maybe the bearing on the output of the transmission. It looks like there is a housing bolted to the trans. where I would assume there to be an axle bearing. Is this bearing difficult to change?

Problem solved -

The first time I changed only the bearing - I think it may have been damaged when it was removed from the knuckle. The guy at the junk yard said that a used bearing needs to stay with the kunckle since it has been "worn in".

Regardless, I got another knuckle / bearing assembly from the junkyard and changed the entire knuckle / bearing assebly as one piece. The two bolts on the strut were a bear to break loose.

While changing it I noticed the lower ball joint was a little loose, so I bought a new one. It took a little while to drill out the rivets and chisel the heads off.

So, now there is no hum and I must have gotten the alignment very close because it tracks straight. I will watch for improper tire wear.
