Do you guys agree and if so, do you think I should send the entire gearboxto Gbox along with $3,500 or should I try to replace the differential myself?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all.
I'm getting a noise from my car which I at first thought might be a wheel bearing but has been since diagnosed by a Porsche Indy as a problem with the rear differential ('99 cabrio 6-speed manual).
Do you guys agree and if so, do you think I should send the entire gearboxto Gbox along with $3,500 or should I try to replace the differential myself?
The transmission has no other issues that I am aware of. it shifts great.
It seems that the differential can be replace in-suto without dropping the entire gear box. Anyone here have experience doing this?

Above is a link to a recording of the sound the car makes. The sound (whomp-whomp-whomp) is independent of clutch position and varies with the speed of the car. its most noticeable when the engine is idling and the car is moving in neutral but i think this is because the engine noise just covers it up. The period of whomp-whomp sounds get longer and longer as i slow to a stop.
In the clip i am at first in neutral moving at say 10MPH until i slow to a stop. i then accelerate (engine noise) and then slow to a stop in neutral again (so you can hear the noise again).
TIA
