    Do your inner rear axle bearings require more maintenance?

    Ever since my inner rear axle bearing seized I've been paying close attention to said bearings. I don't run in water but it appears after every two runs the inner rear bearings get crunchy while all other axle bearings remain smooth even the front inners . The rears get abused a lot or maybe it's just me

    Anyways I now check all inner bearings after every run, and plan on running near neutral camber as I've been running negative for a while. I assume negative camber puts more stress on the bearing. Anywho are you guys finding similar results?

    I had issues with my inner bearings too. I bought some Avids, and I've been using them for 3 months now. There're still perfect, no seized, or crunchy bearings for me. Good luck, just wanted to let you know your not alone.

    Ok I will consider better brand bearings

    One big mistake I did thinking oil was attracting too much dirt because dirt was caking inside the hub carrier making my bearings crunchy I decided to run my bearings dry after a rebuild and... it permanently locked up one bearing and destroyed the other ie all the balls fell out oh well

    All 4 of mine went bad. They were good at the start of my run and bad at the end. Ordered up some better bearings. On I side note I noticed that my local hobby shop has hubs that I think use a bigger outer bearing? But not sure and have not had time to look?

    As far as I know the hub that uses a larger outer bearing is our Summit carrier. As usual here are 2 parts that look identical and dangerously easy to mix up within the Traxxas monster truck family.

    Part no. / vehicle / inner bearing / outer

    5334 / Maxx / 12x18x4 / 6x12x4
    5334R / Revo, E-Revo, Summit / 12x18x4 / 6x13x5

    RPM hubs use even bigger bearings
    "Outer bearings are 6x15x5mm (stock is 6x12x4mm) [or 6x13x5mm - they haven't bothered to update their website to tell the whole truth yet.]
    Inner bearings are 12x21x5mm (stock is 12x18x4mm)."
    but in my experience the plastic is not the correct compound for this application.

    Care to elaborate on the plastic compound? I thought RPM was pretty much bullet proof? I do like the idea of the much bigger inner bearing

    From what I understand our 5334R carriers uses a metal ring/collar to capture the pillow ball, to keep from popping out like jamann said. Visually... unless there is wear on the metal it's hard to detect because everything is black and the carrier looks like one big plastic piece when in reality it's made of 3 parts bonded together. I think a lot of the squeaking noise people complain about is from this metal to metal contact.

    Ooops I made a mistake... sorry. The metal parts are only rings surrounding the pillow ball opening for reinforcement, to keep the ball from popping out and thru the plastic. The rings are snap / pressure fit? not sure. Anywho the pillow ball is in contact with plastic... no metal
