    I am trying to replace Gen 3 P410 transmission differential tapered roller bearing, but I can't find the spec. I had differential out, but the bearing is un-marked, no document available. Does anybody know this bearing spec?

    Do this is for diff. Do it require set up bearing pre load and all that like a reg vehicle diff? All that set up procedures in the manual correct? I have it for other rear ends but not this.

    Good illustration! Thank you! But I still can't find the tapper roller bearing spec on this illustration. Through physical measurement I found my roller tapper bearing is ID 50mm, OD 75mm, width 20mm. Not sure if it is enough. Anybody done this before?

    The one you buy from Toyota will have the right ID, OD, width, roller pitch and taper, steel surface treatment, and every other particular that Toyota required of their suppliers for that part.

    Usually in old days you take old bearing to local bearing dealer to match.
