    Also i have the stock rustler bearings and they seem fine but do they need grease because I cleaned them.

    The stock bearings are sealed so they shouldn't need any lube. Another thing to watch for is the plastic stop inside the rpm carrier can rub on the bearing and cause resistance when the wheel nut is tightened. There was thread on here at one time about it, but that has been a while ago. If that is your problem then you can drill it out to just smaller than the sized of the bearing to make sure it can't contact the side of bearing seal.

    You sure about that? I thought they came with the Traxxas bearing with the blue rubber seal. If so the seal comes off so you can clean them and then re lube them with a drop or two of light machine oil.

    Interesting to know, I was under the impression they shouldn't be "unsealed" but rather replaced. Of course that was information I read on a post here on the forum...definitely good to know, and I will be giving it a try since I have a few that could use some lube or cleaning.

    Metal shielded bearings are not meant ot be opened up you will destroy the metal shield getting it off but the rubber sealed bearings are definitely made to have the seals removed for maintenance.

    what do you think of the traxxas metal sealed bearings compared to the stock blue plastic sealed? I just installed a set of the metal ones today. they seem smoother and better lubed

    You can really tell about a bearing being better lubed? Wow, wish I had that much sensitivity. I wasn't aware Traxxas sold a "sealed" bearing....... thought they were all the blue rubber type bearing that's removable and cleanable. (but I've been wrong waaay more often than I care to remember)

    the metal sealed bearing's are going to go bad just as fast as the blue sealed set. There is just no way to clean the metal sealed bearing's as good as you can the blue rubber sealed set. Traxxas doesn't use the hardest steel to make them, so they will pit and the ball's get cut up and stick. Aftermarket set's made of a good hard stainless steel would be your best bet.

    i reckon removing the seal of a bearing is ok and good but lets face it you don't need to do it very often as look how tight the sel is and anyway bearings are just too cheap to fuss over
    Does more $ = More fun?

    +1 on this.

    I've had this exact issue with some RPM carriers and had to drill out the axle holes to match the bore of the stock ones. The edge of the hole opening touched the inner part of the bearing when it seated and stopped it from spinning freely. I think RPM must have fixed this problem as my son bought a carrier set later and his were OK (i.e. had bigger holes).

    What about ceramic bearings......... now those cost a pretty penny........ can't imagine them being worth the cost. IIRC they're in the $60 price range. Anyone have knowledge on these?

    Ok I called RPM and they said to that I should drill out a small part from the middle and the bad thing is that I don't have a drill bit that big and it will cost more then the part to get a bigger drill bit..... going to buy the Traxxas stock ones now....

    You could cut this out with a hobby knife if you are extremely careful.

    Yup, the tolerances are not extremely critical, but the removal of material should be done very gradually.
