Do you need wheel bearings to hum at 40 mph?
Front is pretty straight forward as it is a complete unit, hence the price. The back is more difficult and yes you should use a puller, however I have watched a youtube video of someone doing the rear wheel bearings on an E46 with ordinary tools and thought I might have a go when the time comes.

What makes a car Hum at 40-60 mph?
All fine… Re: Hum at 40-60 mph. Not wheel bearings wheel bearings. the only real way to tell is to jack it up and check them 1 by 1 by rotating the wheels by hand. You’ll sooon notice the noisy 1. Evil Si. Re: Hum at 40-60 mph.
Why does my car make noise when I go over 20 mph?
If you hear the noise above 20 mph it’s most likely a wheel bearing noise but it’s not a bad idea to check the tire tread to be sure the tires are not chopped or worn uneven. If you what to leave me more details about the noise I may have a more definitive answer to what may be the problem.
What kind of noise does a bad wheel bearing make?
If the noise is a little less if you turn right, the damaged bearing may be on the left, or vice versa. Note that tires that are “chopped” or “scalloped” (worn in patches) also make a rhythmic noise that increases in speed. This sounds very similar to a bad wheel bearing.
Can a wheel bearing fall off while driving?
Your tires will also wear out faster, and you can experience uneven tire wear. Last, but not least, your wheel can fall off completely while driving, as the bearing is an essential part of keeping the wheel attached to your car. Q: How much does it cost to replace a wheel bearing?
What’s the difference between front and rear differential noise?
Only difference between a wheel bearing noise and a rear differential noise would be the fact that the wheel bearing noise will change with wheel speed but usually will not change with load variations (accelerations/decelerations) while the noise from a rear differential will change with wheel speed and load.
Why does the outside wheel rotate slower than the inside wheel?
The pair of driving wheels in a vehicle does not rotate at the same speed during a turn. In situations like this, the wheel on the turning side (inside wheel) rotates slower than its counterpart (outside wheel). This is made possible with the help of the rear differential’s side gears and spiders.
