whining? noise, driver side around 25mph
1990 4runner, manual hubs, 3.0, automatic
I have not been able to figure this out for the life of me. It is hard to describe the noise, it is kind of like a whining noise, or maybe a bad bearing noise. It sounds like it is coming from the area around the alternator/distributor. But it is hard to tell because I can not get it to make the noise unless I am driving.
The alternator seems to spin fine and free without the belt on, no binding that I could feel. I replaced the belt as well, and that seemed to fix the noise for a day, but that could have just been a temperature thing.
I replaced the distributor cover this morning, I noticed it had a couple cracks where the spark plug wires attach. But it is only 9 months old and I don't drive a whole lot. I checked the rotor, it didn't feel like it had movement up and down, just a little side to side.
It seems to happen around 25mph now.
Here are a couple videos of the sound, as best I could do
Any ideas would be great, thanks!

I'll check that out. The tires should be all clear of everything, they are just 31x1050 on stock wheels. Will checking the bearings be something I can do in a parking lot without special tools? Will I need to take my rotor off to do that?

I jacked it up, but when I pulled on the tire, it moved the whole vehicle, it was hard to tell if there was play there or not. If there was play there, it is a small amount and I don't know how I'd tell, maybe if I figure out a way to get it off all the tires or something?
