1997trans-am

I have a 5.3 swapped trans-am with a t56 (Tick Stage 2 (cf blocker rings, steel 3-4 fork, new 1-2 & 3-4 syncros, brass fork pads), 12 rear (spool, 4.10's, 35 spline axles).

Last night, a very loud rattling started occuring as I backed out of my driveway (the spool puts some stress on the driveline components in a turn).. Mind you, this was not a very sharp turn.

I have gone over most of the bolts in the driveline (UMI relocation bracket, adjustable torque arm)

Here are 2 videos of the sound. Can you guys tell me what you think is going on? Makes very loud clicking, rattling sound within the transmission when I rotate the driveshaft by hand (in neutral and in gear)


And


Thanks

Additional question.... can anybody verify the bolt torque for the one bolt that goes through the UMI relocation bracket, through to the poly bushing/transmission?

Thanks

Nobody?

Wondering if it could be a clutch release bearing as well.

Could be CRB. Is it only doing it on shifts?

Put the diff up on stands. Pull the driveshaft. Drive it reasonable but try and hit all fwd. gears; spillage should be minimal. Noise? If yes, you've ruled out driveline & diff.
