Hey Td4 Owners,
I need your help! After an intense off-road trip in Corsica, my Defender has come back with some damage. While still there, it became clear that the transfer case (VTG) had taken a hit — a loud knocking noise made that obvious right away. When I checked the oil, I found that the thrust washers in the diff had disintegrated, along with noticeable metallic debris. As a result, I had the transfer case overhauled and added a Torsen differential and a larger oil pan. So, the VTG is now back in top condition. I also took the opportunity to replace the gearbox extension (output shaft), a known weak point in the TD4. Unfortunately, even after these measures, things still aren’t running smoothly. I made a recording of the noise and would love to hear your opinions. Here are the main issues  :
Noises: Two noises are noticeable. One is RPM-dependent, which might point to the wheel bearing. The other is a constant "rattle," especially loud when idling or in a disengaged state. Could it be the clutch? Oil Leak: Oil is leaking from the front differential at the flange. The oil is fresh, and the differential was recently removed, visually inspected, and resealed — everything appeared normal. You'll find pictures and the link to the audio recording in the attachment.
