Same as described, a "clunk" sound when I release the clutch. Glad to hear it's normal!

This occurs during decel then accel operation, a negative then posative driveline load / torque. I feel ring and pinion lash is the main contributor to this issue. The condition is less sever when the axle is cold and increases after it axle fluid is heated up, possablly caused by lash incease or fluid thinning out. A tighter lash can decrease the issue, but may cause axle problems during high load useage such as race operation. Another contributor is the axle front mount which is a highly loaded component near the back panel of the passanger compartment. This situation can amplefy the noise transfer from the axle to the Passanger compartment. This design was used starting in the 96 design. Pop or clunk in the 94 > 96 could be a loose crossmember or mounting at the front of the axle latter bar that was utalized in those early designs.
Clicking or popping noise under acceleration letting clutch out. Coming from rear of vehicle
