    So did I today, (different RC) and found a bad wheel bearing. Looks like it was caused by a loose hex adapter.

    4wd, rear. Was on my crawler. I could here it every revolution of the wheel. Bearing wasn't shot, but it was worn. After inspecting it I feel it bind ever so slightly. Straight line was fine but when I turned and put stress on the bearing is when it made noise.

    grab the wheel and give it a wobble and see if its got any excess slop in it, take the drive line out, and see if the rear has slope, or feels gritty..

    steering workes ok?? doesn't stay to one direction?? as in the steering horn isnt skipping??

    They don't have to be falling apart to be bad. Take the axle, diff or what ever assmbly they are on out and put the suspect bearing in it's place. Hold the bearing in your fingers while spinning the assembly. You can feel a bad bearing when they aren't smooth. They will feel dirty or can catch a bit. If they are anything other than smooth, they are bad or on their way out.

    say its in a wheel hub, normally there's two in a hub(axle carrier)

    1)what will happen is there will be excess play, and wont hold the axle in there strait and true

    2) it will feel really gritty, almost like there is sand in it, often can mean it needs an oil, or shot)

    3) the bearing is really tight, hard to spin, wont free spin, or wont spin at all.


    hope thats a little bit informative
    theys are the signs i look for in my bearings....

    Wait.
    So my pede's tires wobble pretty bad.
    I've replaced my wallowed out plastic half shafts with mip x duty and it still wobbles.
    It seems like it's in the hub carrier but I can't tell. If I post a thread with a video explaining it could you help me? Thanks!!!

    Don't confuse the slop in the hub for a worn bearing. Almost every RC outside of a solid axle I've had has had slop in the hub to some extent. Some worse than others but it's always been there. Use my method to determine if a particular issue you are having is bearing related or not.

    The STRC aluminum hubs in my EXO are worse than the stock plastic as far as slop.

    some time yeah, like Drzoo2 stated, after marked parts often dont solve the issue. could be a heap of things, wonky rim, wonky tire, bad drive shaft, bent axle, bad hub, bad bearing(even on new cars, has happen to me), could be one of those, some of those, and in worst cases, all of the above!!!! EEEK!! hope not!!! LOL!!!
    I've even seen bad set up on a car cause issues.

    I personally, dont really rate aluminium parts, as often they can cause more problems(in my opinion), from moving the breaking point on the rig, to bad casting, incorrect angles or mounting points, and in race trucks, i've even noting a shift in balance due to the heavier then stock part.
