I'd like to know how critical you guys think these seals are?
While remembering the first 13,000 carriers were built without either seal in them, I can see it might be a problem if a carrier were parked on a serious (rediculous) slope (facing up or down) some of the oil might migrate from the diff. to the gear box, (or vicki verco)
Other than that, I suspect the oil basically stays in one end or the other.
Back in the day, they were never assembled with sealed bearings(as far as I know)
However, someone did though, decide seals were needed and modified the housing to suit, so logic dictates that there was a need.
Is anyone running a carrier that; A. has no seals in it (ie. un modified) and B., Is having problems with oil transfer? (or other issues, like oil in the speedo cable, etc.)
Rob and Michael R, are you guys doing this mod because of problems you have experienced? Or is it because you have later carriers that were made to take seals anyhow?
