Fun fun fun changing my Hub Bearings. Thank god I don’t need to press it out like the old style cars did. Make sure you have a 30mm 16 point socket and an impact gun for the axle nut. Just take out 4 bolts behind the hub and the hub bearing pops rite out with a “slide hammer with yolk from MAC TOOLS” Replaced with TIMEKIN hub bearing $145.00 from eBay [box says made in china, I thought it was made in Japan] I bought this “slide hammer” 20 years ago and only used it a few times when I used to work at an auto shop. So glad I kept all my tools, because it definitely paid me back many many years later! YEWWWWWW Toyota Prius V 2015 @209,000 miles
a small buzzing noise coming from the front end of the car. (In due time it will make a grinding noise) when you put the car on a lift or Jack it up, you won’t be able to tell which bearings went bad. the best way to diagnose it is to drive the car and sway/turn it at about 40mph. if you turn right and sway to the driver side, and the noise gets louder. That means the driver side is bad. if you turn left and sway right, and the noise goes away.. that means the driver side is bad, and vise versa.
I used the same kind of slide hammer doing mine, but it took a very large amount of slide hammering for a very long time, and I was very ready to stop when it finally came out. I think it depends a lot on the car's age and where it is driven. It's not a bad idea to leave the bolts in by a couple threads, just so the final swing of the slide hammer doesn't send you sailing backward with a hub on the end of your slide hammer (and some torn wiring attached to the hub, if it's a rear). There can be times when all rules of thumb (like "how does the sound change turning left or right?") will fail to tell you which bearing is bad, but something like a ChassisEar (little four-channel wireless stethoscope) nails it in seconds.
