Inside of a toyta 8" housing there are small tin pieces within the axle tubes that I am assuming were designed for containing oil to the 3rd member. The problem is that with hard offroad abuse these thin pieces bend, fall out of there little slots, and begin rubbing on the axles. Has anybody found a solution to this problem? Does something similiar exist inside of a 9" rear end that is of stronger design that I can copy? are they really even necessary to keep in there at all? I would guess something is needed there if the factory put them there but has anybody ever run without them and not blown up their rear end? Thanks for the help.
