I have been trying to locate a pretty heavy leak in tcase. new truck and when I got under it, the tcase was pretty grimy head to toe.
I sprayed some cleaner on it, wiped it down and refilled. It was about a quart low. I then went for a little drive and came back to search for leaks.
I found that the output shaft was seal was leaking a drip was forming there.
a drip also formed on the ujoint of the output shaft where it connects to drive shaft and the output shaft housing where it bolts up to tcase looked a little wet around one of the edges.
I bought a seal to replace but output shaft seal but should I do anything further?
Should I pull tailshaft housing and reseal? I can squeeze the boot on the seal and see fluid so I assume that is the major leak spot. I'm ok with a little leaking but a decent size spot every day in the driveway may be a little much for me!
anything else I should look at or replace while I'm there?
