Alright fellas, I know the whole "fix my noise" approach online isn't always the best but I'm just looking for anymore opinions.
Anyway, 88 Aw4/231. Just finished up a transmission and transfer case swap and now have a severe bang/knocking. With the truck on stands and in 4wd it only occurs when hitting the brakes, when driving it occurs when turning and under acceleration. So far I've checked out these parts.
Reset and adjusted transfer case linkage
Tore apart front diff and examed internals, including, ring, pinion and Spartan locker as well as both axle shafts. Nothing abnormal
Fluid in t-case is full and fresh
Fluid in ft diff was water contaminated and was swapped, new fluid was also very milky after being in there for a few hundred feet, fresh fluid will be used upon reassembly
Axle shaft u joints are both tight and clean, lf is brand new along with shafts.
Transfer case was working fine from the previous owner and I have no issues from it in 2wd on the jackstands.
So that's where I am, anyone have anything else I should check out?
