    One of the rear bearings on my 2012 was shot, probably a result of driving offroad while overloaded. The other side was a little iffy as well, so I replaced them both with SKF bearings off Amazon. Threads in here indicated they were a good brand.

    Less than 3 years later one of them failed. No overloading or offroading this time, mostly highway driving. So yesterday I changed them both out for OEM bearings bought from a dealership to be safe. Luckily, I had thoroughly cleaned and covered the mating surfaces with anti seize so they came off pretty easy this time.

    So... either SKF is no longer good or I bought fakes. It's a critical component so probably worth paying extra for known good parts.

    If you're in the rust belt, the old ones can be very difficult to remove. I tried several different methods. The only one that worked was penetrating spray, a big hammer, and this bad boy:


    Also, if you're in the rust belt your dust shields are probably on the way out. You might consider replacing those at the same time since you have to remove the bearing to do it.

    I guess Amazon links are a no go here. The tool I used was basically a heavy steel bar that bolts to the bearing and you smash the end with a hammer. Crude, but effective.

    SKF is still good of SKF authorized dealer is the one who sell it. Too many fake product using SKF or Toyota box.
    wheel Bearing should last 100k+ miles

    Yeah... Sustainability for me means last longer without wasting too much materials and energy.

    It is not like TEMU, shopping like a Billionaire, without thinking how long things last or usable.

    Known good Bearing Brands: Koyo Seiko (Toyota), NTN, Timken, F AG/INA.

    On my Gen 2 ex taxi with 700,000kms, left rear wheel noise, bought a complete rear hub, disc and all, complete with calliper and brake cable from a car dismantling yard, swapped it over but within a few thousand kms, it got much worse, not just after a few kms had been travelled. Orders 4 replacement hubs and when the arrived, jacked one side up, placed the jack stands under it, spun the rear wheel to see if I could hear the noise .... tyre was egg shaped :rolleyes: Fitted one of the spare wheels we had, problem gone, just as likely there wasn't anything wrong with the original bearing ..... Took it off the road some 50,000kms later, still didn't have any wheel bearing problems ......

    Oh yeah...., a bad tires cause a lot of noise, worries, and money. I suspect my rear axle and rear differential on my Sienna AWD at one point. It turns out a bad wear scalloping pattern on the wheel caused that especielly when decelerating.

    Putting our hand and feel it along the ridges and surface of the tires on back and forward directions often help. It is usually caused by non regular wheel cross rotations.

    In this case, the tyre didn't go out of shape until it warmed up at highway speed, the slower run through town to get home to have a look showed nothing.
    The case finally failed enough to create an egg shaped tyre, nothing obvious as far as the tread, not until it was off the car and rolled did it become obvious ..... I was actually about to do a front/rear tyre swap to see if the noise moved to rule out the tyre being the problem .... when it didn't roll as expected, the question was answered ..... should have carried out that test before I ordered 4 new complete hub assemblies ..... had projects planned to use them, then the workshop burnt to the ground ...... so that ended that .....

    I feel you man. Many of us did unnecessary replacements caused by our wrong diagnosis. That's why for something not obvious, we should asks professional to do that. And sometimes 2 or 3 opinions are needed before do any repair.

    I replaced control arm on Sienna that cost $800 in the dealership, or $500 from my local mechanics. It turns out Walmart balance the tires incorrectly. It vibrate only at certain driving condition. It was a lateral stupid balancing that misplaced the balance weight on the inner or outer side of the rims.
