Front Bearing Removal Tool UPDATE PROBLEM SOLVED!

[andrewwynn]

70 is about 103 ft/sec out tires are 5.7' circumference so 103/5.7=18.07 Hz at 70. 18*4.1=73.8 Hz aka 73.8*60=4428 RPM. That's definitely fast enough to be a problem with a small weight off balance.

I'm a little concerned about the possibility of under load causing an issue but that would be very similar to my theory of my under braking causing vibration.

Do you get UFO noises when backing up?

No UFO noises. That's why I didn't think it would be a wheel bearing. All the reading I've done on it the common denominator with a wheel bearing is the UFO noise. I'm not getting a crunchy noises from my CV joints either so

Do the test I described where you loosen the axle nut, tap the axle in a few mm (leave nut on just loosen a couple turns) and check for play.

My bearing which was silent with 235 tires but howled with 255s was stiff even with rotor on was wobbly even with just the hub once I removed the axle.

That reminds me; usually I can knock out the hub in a minute with a slide hammer but this time it was a beast to remove! It's so much easier to remove with a bearing separator plate and 55-60 mm M14-1.5 bolts.

I'll give this a try. Maybe this weekend. Not sure as it looks like rain moving in again.
