TCase post-install help PLEASE - Pirate4x4.Com : 4x4 and Off-Road Forum

Hello All! My truck is a 6/1980 FJ40. I just had my tcase rebuilt , and after installing it something is 'dragging' intermittently. It causes a 'growling' noise after taking off from a stop. I disconnected the rear driveshaft, and, turning by hand with transmission in neutral; the parking brake drum(rear output shaft) will rotate fine backwards; but will only go about 1/2 revolution forward and then 'clunk' it stops. If i rotate it backwards a turn or two, i can then rotate it forward again about a half turn, then 'clunk' and it stops again. After it stops, with force it will turn forward, but with much resistance- i suppose this is where the growling sound is coming from when i drove it. To tp off my confusion- after a few times of turning backward, then forward- it will rotate fine forward and backward with no stopping?????
The parking brake is adjusted all the way off, so it is not grabbing until the lever is pulled all of the way up-just to narrow down the problem. Any help would be GREATLY APPRECIATED!!!!!!!!! thanks! Chris

What about pulling off the PTO cover and taking a look inside?

Are all the shift collars in the correct place/oreintation?

Was a gear put in backwards? Maybe a wrong spacer?

HTH???

The adjusting lever for the parking brake drum probably flipped the wrong way and is catching on the drum. take the d-shaft off, the parking brake drum off, and see if the dragging goes away.

note: if you pull the drum off, all the lube will come out of the t-case
