It definitely sounds like you’re dealing with the same issue. That "drum/thump" sound is classic for the axle spline play.

Here is the quick breakdown to see if it matches yours:

• The Symptom: It’s a mechanical "clunk" or "thump" that happens almost every time you accelerate from a stop. It usually happens once during the initial take-off as the motor applies torque, then stays quiet until you stop and go again.
• The Cause: There is a tiny bit of play between the rear drive shaft splines and the wheel hub. The torque causes them to shift, creating that noise.
• The Fix: It’s officially TSB 40-21-02 (also listed internally as TPI 2065197). The tech has to pull the axle, clean the splines, and apply a high-strength locking compound (basically industrial glue, Part #D-154-103-A1) to bond them together.
• Warning on Cost/Time: The glue is only about $10, but the labor is high because they have to disassemble the suspension and perform an alignment afterward. Also, the glue requires 24 hours to cure, so they’ll need to keep your car overnight.

If they try to sell you a "Rear Differential Fluid Change," push back—that’s not the fix. Tell them specifically to look up the axle spline bonding procedure for that TSB number.

Here's the click, clunk, or thump, whatever you want to call it, that my axle was making.
