    I've now bought twice here on this forum from 05Taco4x4 and will buy a 3rd time when needed. I was under the belief that you can not buy a pressed into a hub assembly OEM. You can by the 3 components (bearing, hub and seal), but they must be pressed. Someone more knowledgeable than me can confirm this. The couple of shops I spoke to told me that pressing that bearing into that hub takes some care and skill and they prefer not to do it and rely on preassembled units. I had someone from a local machine shop that calls itself Bearing Service tell me the same. I determined that the unit sold by 05Taco4x4 was the easiest way to to source a hub with the NSK bearing pressed in. The most recent hubs I received were a made in China Dorman hub with a Japanese made NSK bearing. I have no experience with the TORQ or other assemblies.

    I'm glad and sad I found this thread, it's unfortunately well timed.

    Just ordered new assembled and pressed hubs from @05Taco4x4

    I've had this hum and harmonic thump that I can only really feel in the gas pedal around 40-60mph and it sounds like I have mud tires when the Cooper ST Maxx's have always been quiet.

    I was assuming either my driveshaft was unbalanced and or the tires were getting louder but now I'm feeling a little micro rumbly feeling at low speeds and confirmed last night on my way home after reading this thread when I lazily swerve during a lane change and the weight transfers I can here the noise lessen and greaten left to right left to right with the weight shift.

    Damn.

    Suppose I got my money's worth, 5 years since I got the truck, it had 170k miles and I've put on 80k more.

    Guess it's time, a bad time but what you going to do?

    Going to try and get gusseted spindles to put on with the new hubs at the same time from @m00seNUckLEz

    Does he have a web storefront? Or is this done by forum PM? How much do they cost?

    I used ones built by a member here the first time. He isn’t a member here any more.
    They were “expensive”. They failed about 3 years/34k miles.
    The second time, I was aggravated about the goods ones going “bad” so soon.
    So, I order the “cheaper” Beck/Arnley. I don’t know what Bearings they used. I didn’t look, it was 90+ degrees outstanding and I just wanted to get it done. So far, they seem to be fine. But I only have about 10-15k on them.

    I don’t know why the first ones went bad so soon.
    And I can’t/don’t blame the builder. As I said, I have no idea why they went bad?
    But I’m stubborn, and figured why spend a lot of money again, if the “cheap” ones last just as long.
    I guess I see soon enough, huh?


    If I were looking for GOOD bearings with great reviews. I’d recommend @05Taco4x4 assemblies.
    I’ve heard nothing but GREAT stuff on his stuff.

    that sucks that you bought what you anticipated to be good bearings to soon find out they were in fact bad. That justifies taking a chance on less expensive generic bearings. I would point out that changing or at least closely inspecting the seal that lives on the backside of the steering knuckle is a best practice along with properly torquing the axle nut. Both a bearing with too much preload and not enough can cause premature wear. Banging that hub assembly away from the knuckle on a 90 degree day would be most unwelcome.

    At 85,000 ish miles I replaced both front wheel bearings. Neither had failed or was making noise, but were originals.

    I purchased Timken bearings, fully greased them with Mobil 1 grease, and did the press apart, press together myself. Was not difficult, but did require fabricating an aluminum sleeve to press them on. Tightened, torqued and saftied the nuts.

    Recently, I have been getting a droning noise that happens around 40mph, diminishes a bit, then can be heard above 50 until it quiets at faster speeds.

    I too tun Michelin tires, think LTX but would need to check. Even rotated the tires with no change.
    Definitely not air conditioning as turning off / on has makes no change. Unlikely it is driveshaft since lifting or accelerating makes no change nor does shifting to neutral.

    2010 Prerunner, 88,000 miles since new. Will verify front bearings are still tight without freeplay, but suspecting it is tire noise.

    Do you have a press or did you do this with a vise and hammers, etc? I jacked the front end up to check my bearings (originals with 127,000 miles) and they feel fine. Road swerve test also negative. My noise feels more like an exhaust resonance. And it is not really rhythmic. I replaced the muffler with the Toyota OEM assembly about 2 years ago so it is basically new. No exhaust leaks that I can find. This is going to remain a mystery unless and until something gets worse. But I probably should do the front bearings anyway. They can't last forever, can they? ;-)

    Done using a press and high end torque wrench. I suspected exhaust also, but no change if increasing revs via a different gear. Even removed the serpentine belt pulleys and checked them.

    I just started getting the humming noise yesterday, so I'm looking on here for answers. 2013 TRD Sport 4x4....104k miles with a level kit installed a year ago (1.75" lift in the front). new wheels/tires installed at the same time....-12 offset, no spacers, stock size toyo AT3s. no previous road noise noted at all, i bought the toyos for the low road noise rating. bilstein 5100s up front to provide the level.

    The noise comes in at 57-63mph ONLY. I havent tried cornering yet to listen at that speed for a change. I did just change the spark plugs/cleaned MAF/clean PCV this weekend, but the noise doesnt change based on engine speed. i bumped it over to 4th gear and the rpms jumped, while the noise stayed the same. also tried with the a/c off and on, no change. There is no vibration at all, just a drone/hum sound that is new.

    I did drag my passenger side rear wheel into a curb this past weekend, caught it pretty abruptly. could that have damaged my right-rear wheel bearing? sharp right turn in an area i wasnt familiar with, ugh.....

    Rear wheel bearings will do that funky 40mph hum, diminish, and then return at a higher speed. I tracked that issue in my old 09 and it turned out to be a rear left wheel bearing...
