    I'm thinking about swapping out both front wheel bearings to try and rule out a slight vibration/growling noise that I feel in the floor at around 60 mph. I've had the truck lifted and I feel no slop in the tires but a guy on here said his bearings were shot and they felt solid as well.

    Can I buy both the hub and bearing assembly already pressed together? or do I have to buy the bearing and get the shop to press it in for me?

    Or is this all I need?

    ^That's the bearing assembly, the hub presses into it. You have to either press out the existing hub from the existing bearing then re-press the old hub into the new bearing (with the 4 bolts of course) or buy a new hub (and the 4 bolts) and press it into the new bearing. Some people have been able to get the existing hub and bearing apart, I had no such luck. When I changed the drivers side I had a 3' long, 3/4" ratchet on a puller and it just bent the tabs on the bearing assembly and didn't come apart. Pretty frickin ridiculous.

    it does. I have been told you can buy that assembly at O'reilly auto parts but I can only find the "hub assembly" for the rear.

    i had to replace a wheel bearing not too long ago. i dont remember really how we did it cuz i had a guy i know help me out. i do know that all i bought was that part pictured above. it was kind of a pain in the ass getting i think the old bearing seal off of the hub, something like that, but we got it.

    just make sure it is your hub in the front that is making the vibration. I had slight vibration and i was told it was hub. I purchased a $175 hub and it wasnt that ... now i have a rear hub sitting for sale. It was by U-joints ... Let me also tell you something if you dont know anything about hubs, or if you havent changed them previously i would recomend not trying it. Its not as easy as it looks just an opinion.

    also i forgot to mention. when my bearing went i could move my wheel back and forth probably a half an inch or so. it was bad. i didnt even drive the truck till i fixed it, cuz of have so much play in the wheel, it also grinded like hell going down the road. if your bearing gets as bad sa mine was youll deffinitely know it.
    we pulled my bearing out and it was nothing but metal shavings and lose ball bearings lol..
    so if you think its a bearing you might wanna change it before it gets as bad as mine

    I hate these damn wheel bearings, they're so confusing to try and explain.

    Alright, so I'm guessing it's different for the PreRunner vs. the 4x4 given the absence of a front axle on the PreRunner. I've done it on a 4x4 and it's a pain in the ass to explain, but when you actually get your hands on it it's pretty straightforward.

    4x4: I'll reference the diagram trdparts4u sent me shown below. The wheel bearing assembly (pt#43570/80) bolts to the spindle, and the hub (pt# 43501/02) presses into the bearing assembly. The 4 bolts that connect the whole mess to the spindle (pt#90301-a0167)get sandwiched between the hub and wheel bearing assembly.

    [​IMG]

    PreRunner: I haven't done this and I can't find a diagram, so my best guess is there's a cap on the inside of some sort and the hub might be different (not splined). Without the axle, you would have just the press fit of the hub in the bearing assembly holding the wheel on.

    If I were you I would contact the guys at trdparts4u.com (info@toyotapartsales.com). They sent me that diagram and helped a ton when I was figuring it out for my truck.

    Jackpot. :thumbsup:

    And keep in mind if you can't get the old assembly apart to reuse the hub you'll need to buy 4 new bolts along with a new hub.

    You loosen those 4 bolts (17mm I think) and take the axle nut (35mm) off, then the hub/bearing assembly comes off the spindle as one unit. The 4 bolts are trapped between the hub and bearing, but they have enough room to be loosened enough to remove the hub/bearing assembly. Then you attack it with a puller to separate each piece and a press to put it back together.

    Thanks for the diagram,

    I've been doing alot of research about the front vibration/shimmy while doing about 60mph and some people had mentioned the front diff as a potential problem..not the wheel bearings. Well I changed my front differential oil last week and this little piece was stuck to the magnet. I have no idea what it is but I do know that it is not supposed to be stuck to the magnet. Could my front differential be failing?

    I'm going to create a new post on this as well..

    Thanks for everyones help :eek:

    Taco, that looks like the exit slug of a drilled hole. A metal chip made from "breaking thru" while drilling. Aluminum is famous for this. Although aluminum isnt magnetic. Im not sure what the material for the diff housing is, or if that even is an exit slug.
