what are the specs of your truck? dual cases? lift? can you make a video of the noise? picture of truck? is your driveshaft out of phase? is your pinion angle correct based on type of driveshaft? toyota gear driven trans/transfer case can get noisey/rattle if these things aren't correct. there is no such thing as a brand new trans/transfer case for that truck as far as I know . did you have it rebuilt? by who?
1980 20r swapped the l43 for the w56, had the rear drive shaft shortened and balanced at a shop, tranny was not rebuilt but out of a wrecked truck not in pick in pull or a wrecking yard
Maby a old school 3" pro comp lift but can't be sure for certain. I'm not sure if the angle on the pinion is correct tho. It's a fairly straight shot. The truck is a long bed/ single T case so I figured I wouldn't need a Cv for the rear drive shaft
