My T-case has been squealing for a while, primarily when you depress the clutch to slow down, or when you are in gear but decelerating. It never squeals when under acceleration. On the way home Monday, the noises suddenly got more pronounced, a bit more clanky. I haven't driven as I am going through some elimination issues first.I drained and refilled the r380 gearbox and everything looked good (except the old oil), nothing unusual and no metal chunks. Today I am doing the same for the t-case, but am waiting for a 1/2 inch drive socket to arrive to remove drain plug first. I live in western Kenya (from Virginia) and tools and supplies are at a premium. My plan is to check the level of oil, drain anyway, remove bottom plate and inspect. I can update afterwards but didn't know if anyone had any thoughts ahead of time.
