Hey all - '01 Tacoma, 4wd, 104k miles, original owner, stock daily driver other than the ARB bar up front (keep the deer and elk out of my radiator!).
I've got the breather for the front diff (the one located under the hood tucked along the driver's side inside fender well) that keeps burping up gear oil.
I've pulled the one way cap on the hose, and it is functioning properly.
I've pulled the soft hose down to the hard line, and it is free of cracks and defects, and is not blocked (obviously since it is dripping!).
I've drained the front diff, and changed brands of gear oil two separate times with the mftr suggested 75w-90. No shavings or metal flakes stuck to the drain plug magnet. When refilled, I went to the bottom of the fill plug, let it settle, and replaced the fill plug. Took the approximate 1.25 quarts as it was supposed to.
At a complete loss - my mechanic thought that maybe it is indication of a seal failing somewhere on the front axle, that is small enough to allow air in and cause the breather to "burp" but on his lift I couldn't see any signs of oil leaking anywhere other than the breather hose. Right now, it is dripping a fair amount, but when I drained it there was plenty in there.
Anyone with any thoughts or suggestions?
