Hello, could anybody advise me with my differential issue..

Unusual noise is coming from the diff, dips and delays are felt when releasing throttle and subsequent acceleration.

This constant extraneous noise presents always, but it's best at speeds 40-65 mph, the higher the speed, the higher the pitch of the sound.

Metallic clicks are also often heard when starting off. I checked the CV Axles but no backlash was found. The only play is inside the differential, if you check through the drive shaft..

The dips and delays are very similar to the late operation of the solenoids in the automatic transmission, however, my tranny and TQ are after disassembled full revision, with replaced TCM.

I bought everything but in doubt, do I need something else for diff restoration ? I bought for GM 8.6" IRS and hope it's exactly my diff.

Gear oil ACDELCO 104016 and additive for LSD ACDELCO 104003.
